That's regardless of Asetek makes all the AIO's that get rebranded by the third party guys (Asus, Corsair etc) Arctic is a brand that is renowned at making excellent cooling I've noticed that most of the time, even in IDLE, I have a voltage between 1. It's an offset, so lower values = higher clocks at lower voltages. The limiting factor is the instability of the core, which is greatly affected by temperature. 0500v and Generally speaking for a while now I was just running the 5950x stock with a negative voltage offset of about . -Asus TUF Gamming B500M-4x8gb Crucial Memory-750w Power Supply. Curve optimizer is not technically an undervolt it’s a boost curve offset the voltages used are still determined by your standard motherboard limits and other PBO settings My 5950x has a lower single core score which reflects a Ryzen 5950X temperatures and voltage Ryzen 5950X temperatures and voltage. Let’s continue and set a -30 Curve Shaper for all temperature points at Medium Frequency. Thread In the PBO menu try using curve optimizer to set a neagtive offset which should bring the voltages down a bit. For example, pushing the voltage, on a godly binned 3900/3950x, that can run real 7nm voltages (less than 1. Probably you guys have more experience on this. I always run prime 95 to test for system stability and was horrified at the temperatures I was getting. If max healthy voltage is i/e 1. I tested 3 new 5950X during the last two months, and none of them were stable at stock settings. On full load it'll behave as constant 1. Instead of cranking the PBO Scalar to 10x you should've tested it with 1x, then 2x etc to see what gives you the best behaviour. You didn't say which MB you have but with most you can access BIOS, set manual voltage control to Negative Offset and enter -0. Set CPU voltage offset mode +0. 875GHz) So it seems But doing a negative offset should be safe, but it's unlikely to do much more than cause less boosts or crashes if it's a Ryzen 3000 chip with only all core offsets. I bought it two month ago in Germany from a local got some insight from a good chap over on Reddit who told me to try PBO again with CO but give the bad core a POSITIVE offset. 0% gain in multicore performance realized with optimized settings (PBO2+Curve+Boost) 12. Theoretically this should finally allow overclocking Increase it by 10 amps until crash/thermal throttle/scores are lowering which can be done on desktop with Ryzen master, then pull it back to the last best results. 05000/ 1. Now my questions are: Best way i to use and apply negative Voltage offset in BIOS, typically -0. adaptive + offset core voltage 1. SoC at 0. Ryzen 9 5950X Curve Optimizer to 5. moab600, Oct 7, 2022 #3. 7-5. Bios : 7C35v1D2(Beta version) ANYWAYS, Quick and dirty. Apply the offset and observe your system’s behavior. Step One. Stable and well, so voltage is set a bit above what is needed for 99% of chips just to ensure that even the 1% worst-performing chips are stable. Joined Nov 27, 2023 Messages 2,635 (6.

Thank you . What Curve Optimiser does is apply a voltage offset, positive or negative, to each individual (or not) core’s I present you my results done on 5950x with offset mount ALFII 420 AIO as cooling solution and NT-H2 paste. Finding out minimum offset values down to +/-1 is tricky, days of running CoreCycler. (5950x) Since I reduced them, no more crash at idle. When I I know most chips won’t do 2000 fclk (seems less common on the 5900x than 5800x or 5950x, and not strictly lowering the voltage, it’s not like a negative offset undervolt. For the 5950X this value is very important because given the chance your CPU will not hesitate going there given the workload. r/Amd Hi there guys, just an small post to gather some curve optimizer negative offsets on your AMD Ryzen 5000 series. More posts you may like r/Amd. All the best ASRock TSD Try with some (-0. Using Asus DOCS transition at 80 amps and EDC of 90 on 5950x I can hit and hold 5200mhz effective single and 4730 effective all core in R23. Mannually overclocking with low voltage or set vcore offset Reply reply With a voltage offset larger than -0. Instead of fixing the high voltage with a negative voltage offset you decided to apply a (way too low) static voltage and then decided to overvolt the SoC. 05v core offset, some can get away I tried different LLC, different negative Voltage Offsets, and while all did lower voltages, it also came at a cost of performance based on how the PBO curve works. Though honestly I'd just disable PBO, with my 5600 the difference between PBO on/off (4. Jump to Latest 141 - 160 of 269 Posts. New posts Search forums. Don't tune CO before dropping EDC, it will result in instability. Motherboard: ASUS Tuf x570-Plus (WiFi) BIOS Version: 3405 RAM: 4x16GB CORSAIR VENGEANCE LPX 3600MHz CL18 PSU: Kolink Continuum KL-850PL Please take note that this offset voltage may not be the same for your chip as I discovered higher core count CPUs can do -0. The only way to keep the system stable is to increase offset voltage on CPU on about 0. I don't have my parts yet, so I'm also a newbie to this. 8800/ Edited* I updated my voltages I run a 5950X on Crosshair VIII Formula primarily for encoding with Handbrake. 25V, you'd go 1. With that, you can try to find lowest voltage (highest negative offset), starting with -5 or -10 all core. 8mhz . The CB23 Run the CPU and voltages at stock. I put in the sub timings from DRAM calculator, pushed voltage to 1. 5950X. 00625 or +0. Site CPU: 5950X MB: ASUS X570 E-Gaming RAM: Gskill 3600CL18 32GB There are also negative voltage offsets or 'counts' that may or may not help. All Cores will allow you to undervolt each core at the same negative offset. SKILL Trident Z DDR4 Hello y’all, I’m just a little concerned with the temps and voltages of my new Ryzen 9 5950x. 050mv Set LLC to the 2nd lowest level Load windows and run cinebench r20 in both single and I am very much worried looking at the temp. 0500) the curve will actually chop from the output voltage or there is some odd relationship between all the cores and Real talk. 1 SOC, 1. Out of the box my temps on the 5950x Forums. My temperature remains 75C and sometimes rises above 80C. I am also running CPU voltage offset - 0. With stock clock settings and that negative voltage offset I was seeing reported clocks of 4725 mhz but effective clocks of Setting any kind of voltage offset absolutely demolishes performance by CPU not boosting properly. Only set pbo enable exit that go on cpu voltage enable offset mode negative and press minus key. When setting Curve Optimizer to -15 for multi-threaded workloads, the voltage is reduced by 6mV by simultaneously increasing the TLDR: The system slowly and progressively became more unstable, disabling PBO and adding a +0. Dependent on mobo, chip and BIOS, I've found best results are typically between -0. Discussion Running into some really odd behavior since getting my new 5950X. 35 fit voltage and there never will be. Enabling PBO was the solution. 05 to - 0. The CO offsets are different, you need to start from scratch. I was totally perplexed why light loads would sometimes crash on my 5950X (just the app not even BSOD) but heavy loads were rock solid stable for extended periods of time with aggressive memory overclock, even at -30 Use curve optimizer to offset the voltage a bit should partly reduce the operating temp. With 5000 series the curve optmiser will allow the good cores to have less Temps don't break 70C on CBR20 With PBO I'm hitting way higher temps and voltages and scoring around 10,000, plus drastic voltage fluctuation, not stable adaptive changes to loads. On stock settings, the cpu goes 50-55 degrees on idle. These settings gave us an average I use curve optimiser and each core is tuned, Scaler x1, no vcore cpu voltage offset. 1 below) So further undervolting my best cores was a bit too much and I got some errors running the single core test in SSE,AVX and AVX2. But notice that don't offset too much, particularly for core 0 and core 1, because those two are frequently boosting to 4. 4v voltage. It needs good testing though. System Those temps are fine for Zen3 processors specially under an air cooler. Zero OC. In the BIOS Setup of my motherboard, in addition to the obsoleted Vcore offset and the new Curve By default, my motherboard sets it to Level 5 (lowest voltage Don´t worry about it. i know its overkill but i mostly game on my rig and sometimes i stream, currently running the 5950x, rog crosshair viii extreme MB and corsairs h170i That offset voltage looks like the right one to me. My 5950x+B550 Tomahawk+4x8GB B-die won't post with RAM at > 3466 no matter what SOC and DRAM voltages I set. 12/day) System Specs. I've also done it with Manually setting VDDCore with "+" offset for droop to get to higher frequencies but I do what another poster said. 3 and 1. 9. 948v Vddp at 0. I'm guessing that there's a toggle that I'm missing. Of course, you can reduce the clock value too but for me, the best results came with undervolt. It varies from case to case as not all CPUs are created equal. The lower your curve offset the more clocks you get for a given voltage. 0875 offset with PBO turned completely off. Running a 5950x at -10 all cores with +200mhz boost and x4 scalar, get 10. BIOS\OC Tweaker\Voltage Configuration CPU Core/Cache Voltage set to "Offset mode" Offset voltage(mV) set to -100 to meet your -0. 4k FFT tests would push temps to 90c, my cores would go waaay past 4ghz and the CPU was using >175w of power! Try -18 all core, offset the CPU voltage with -0. The graph sharply rises as the frequency increases. the whole reason for people to go with a negative curve offset is to lower voltage per core and in I wonder wich offset for this processor is normal. 097/ 1. 05 - 0. On my 5950x my two best cores can reach 5200 while others on ccx1 do 5050-5100. Start with a conservative negative offset value (e. 03v That should give you pretty close to the highest clocks you can get with PBO For my 5950X I run 280 PPT, 210 TDC and 190 EDC; but I am doing so with CTR which allows me to force much lower This make sense why the problems are mostly observed with the 5950X where all the cores are enabled. Oct 16, 2017 9,876 2,662 62,790.

I'm not It’s called the “Curve Optimizer” and lets you modify the factory programmed Voltage-Frequency Curve when using PBO. It gets closer to 65C if I let it run through Cinebench R23. 000 in Cinebench R23, What I meant is start the curve optimizer with a negative voltage value, it should boost the R9 5950x/Skylake 6400: Processor: R9 5950x/i5 6400: Motherboard: Now trying to increase the negative offset on the low boosting core did not seem to make any difference. Thread starter redc0de; Start date May 13, 2024; R. With LLC and Offsets: AC: 4. 9GHz+. So a core with a -30 offset will run faster than a core with a -20 offset with the same power draw. CPUscrub. 2V+0. 0625V I saw "clock stretching", or the CPU claiming to run at a higher MHz than it really does (Core Clock is noticeably higher than Core Effective Clock in HWiNFO while My 5950x idles at 50-60C and only hits 80+ under synthetic load. This also make sense why negative voltage offset is making it stable, as it can't boost to unstable 4. 35V and the maximum boost I've seen it get to is 4. Sort by: Best. It is the only voltage 'proven' to not degrade or damage your chip long term. 00V SB Voltage 1. Here is a Before and After. 65GHz) is negligible for gaming I got the Ryzen 9 5950x, and I have been trying to push it to see the max frequency it can run (having seen that a lot of people out there seem to easily because if I was stable at -15 all cores without any voltage offset, then going to -16 is just a 3 to 5mV difference from what I understand (each increment in CO is 3 to 5mV The benchmarking scores I get are similar / the tiniest bit higher with the offset dialled in. Think of offset as voltage reserve you can use when needed. ----- I have a brand new 5950x paired with DDR4000 and a gigabyte AORUS x570s. For Just put together a new build and ive noticed that my 5950x is boosting for no reason, just idling watching youtube/twitch its boosting itself to 4. It's a long and grueling process to get the most of. Additional voltage would only cause the performance to deteriorate and no manufacturer wants that. Doing it manually per core and finding the The maximum voltage range, allowed by standard condition, is dictated by the silicon quality of the chip itself. The better your cooling the lower u can go. View attachment 2468214. 75, scalar 10x and no override/OC and see how it goes. R5 5600X-(Bykski CPU-RAY-ON-M)_ROG STRIX B550F-Gaming_RX6900 XT- I've reduced it and increased it by 0. 3v, I did this with my 5950X quite successfully - use the Offset voltage with a negative value. Is using curve optimizer and voltage offset redundant? upvote The 5950X ram at crazy high voltages all the time and caused it to be 70c on idle for me. 3 on 1 CCD and 4. Just like how many many 5950x chips wont reach 1900mhz FCLK without throwing WHEA errors and having So for the previous example you might get 1. Even with C-states disabled. Joined 6 Feb 2019 Posts 19,000. 5800X/5900X/5950X all beating or losing So i lowered the frequency at 4400Mhz and the Voltage to 1. The actual voltage is going to be different to that, and assuming there is only a single voltage set for all cores it will be based on the highest voltage requested among the cores and possibly other parts of the die. so. 4GHz (please provide all the values for volatges for in between speeds if poissible). 25v mem, and jedec timings (not XMP or DOCP - it's just to hopeful to dial in lower timings without significantly increasing voltage). Chip overclocks well with standard PBO and also with CCD overclocking, The frequency even dropped if the voltage offset was too high. The processor also doesn't get warmer than 55C in a ~26C room when running a game. 35v. The logical procedure would be to set an Offset to 0. To make them 1:1 to start how much do I +increase voltage on all cores in the CO per step of negative offset voltage. 05v, Custom power plan and negative offset voltages is great for Ryzen 3000 (3900X) temps, check it out . 17500/ DRAM Voltage 1. 1 GHz, PBO and Only the voltages for frequencies between 4800 and 5700 MHz are affected. 2x360mm custom loop.

Reapply XMP. This gives another 62. I'm still doing more testing to validate The 5950x is definitely a completely CPU: Ryzen 9 5950X | Motherboard: MSI MEG B550 Unify-X With Curve Optimizer set to -25 it was necessary to add a voltage offset of +50 mV in order to keep the system stable. I can run my 5950x with most of my cores at -25 offset, (Rated) to 3200MHz, updating chipset driver, updating NVMe driver, adding a small offset voltage to Vcore and Vsoc (something I saw on AMD's forums). CLDO VDDP to 0. Check ZenTimings to make sure your infinity fabric speed isn't applied wonky. Unless you intentionally override the voltage by using either the voltage offsets or the manual mode, the CPU is being delivered whatever it is asking. EDIT: Fixed the curve optimizer value, confused it with the clock speed offset value. 700v, vddg at 0. 9ghz and around 1. It's not uncommon for me to run 7-10 days at constant 90%+ CPU load. 2. 27 Jul 2021 at 12:19 #9 Grim5. 935V. Currently, I I'm running an undervolt with all cores set to negative 16 offset and PBO on in the hopes that I can So it I'm working on undervolting my build (5950X / ASRock X570M-Pro4, small mobo with not-great VRMs and not-great cooling so undervolting is kinda important for me). Credit Information: Ryzen 9 5950X Curve Optimizer to 5. . Most of this has to do with the fact that the CPU will still turbo boost to the maximum frequency under light loads. Set mhz override upward 1 notch a time, until you get instability and adjust CO offests to At the end of the day I went with his 3rd option and set voltage offset to -. Save Share you may be going to far negative for the calculated Fitness of the silicon to attempt to boost to the frequencies you are expecting. Use Ryzen Master to identify Second I noticed when I was applying a voltage offset with a positive sign and say 50mv (+0. Depending on your CPU’s cores and your system configuration, the automatic optimization process will take around 30 to 60 minutes and may restart your system a few times, (Dark Hero VIII + Ryzen 5950x) Quad rank Ram Setup results in memory errors in AMD 500 & 400 Series 03-31-2024; Undervolting my Z690 - Intel Extreme Tuning Utility not allowing me to change the voltage offset.

But when I do this in the Bios MSI, I start the computer and my core voltage is blocked at 1. Aleksandar Miljkov said: Here are my results after a bit of fiddling, using a 5950x. 05 offset, and set boost clock override to +50 and cpu is stable through OCCT test. If I configure a + Offset for the CPU voltage (where it adds the specified offset voltage to the standard voltage), it seems to eliminate the issue. what should be the voltage valus for all cores (I use 30 cores continuousely) 4GHz to 3. However, I managed to get should I keep CPU offset at +0 RAM is doing 3600 Mhz 14-15-14-32. You should definitely go in the BIOS and attempt something like 1. For a start, the 5950x, whilst possible to work with an a320 mobo, will throttle like hell. I tested with default, PBO settings and cor0 was also unstable with any negative offset. When I play games like Apex Legends or Halo Infinite, my CPU goes up to 75-85 degrees. 1 or -0. In BIOS, the offset thing is negative 30. A small -voltage offset seems to help too (-0. your motherboard might allow you to use "Offset Mode". Reply reply More replies.

Pretty happy but do I have room to improve and is the negative CPU voltage offset a good idea? Core Voltage: Auto with offset below CPU Offset Voltage: -0. Go U can see in CPU-Z voltage offset and PBO2 is working. Also, under external voltages settings in the OC tweaker tab, I set CPU_SOC Voltage to fixed mode and the fixed voltage to 1. too low of LLC causes too big of a droop which may require significant base voltage to overcome (technically nothing wrong with big droop, just difficult to set voltage and may have high idle temps due to high base voltage). Please go to the below BIOS path to set the CPU offset voltage. 234v offset, my voltage would still be within the community recommended 1. 5mV offset over the Precision Boost The 5950X's issue isn't that it can't boost high because of limits Basically, you're just doing a bit of a under volt with a voltage offset per core to help bring temps down for better PBO boosting. Thanks again! Reactions: freeagent. It is running very hot overall, web browsing can push it to 60C. 25V. It made no difference -my objective was to OC generic 2400 DIMMS to 2733. Tune CO, add in 1 notch of positive voltage offset(+0. D. I have also attempted several different negative voltage offsets, with less than ideal results on all, in balanced or power saving modes. 1 V. 15v to match SOC/Uncore. 165V, -Ryzen 5950x with 280mm Corsair AIO cooler. 123500 to ensure Asus hero VIII WIFI is not pushing too much V to the CPU The default Those Ryzen 5000 CPUs can be quite a bit power hungry if you let them behave like they want to, which is why today we're setting this R9 5950X to be more per Leave PPT. 1125v PBO Settings: everything set to Auto LLC: Auto CO Aorus x570 Ultra, Ryzen 5950x - PBO, CO I have been working through various guides and methods to find the best outcome for my 5950x. under load and Vcore voltage is a lot lower. If you monitor with Ryzen Master, the 2 CCD's should state the max clocks at the top of their active clock chart My 5950x barely hits 80 during stress testing with this setup on a 360mm watercooler, For comparison my 5950x voltage. I've used Core cycler to set up my The board is not controlling the voltage, only delivering it. Ran 2 I wonder wich offset for this processor is normal. 05 to -0.

No voltage offsets - everything on Auto. The 5950X will boost to 5. Yeah the other cores are able to undervolt more and still hit 5050-5100 stable. You didn't say which MB you have but with most you can access BIOS, set manual voltage control to If you can do your own stability testing, you can see if your vcore setting in BIOS has an offset option, set it to negative offset, and try different negative vcore offsets. 05GHz for very short periods of time under light loads with just PBO enabled. 4 volts. 1Ghz that do requires I would also highly recommend using a voltage offset for cooler temps/higher clocks. This voltage offset has fixed it (for now). With the current cooling solution it should have plenty headroom to stretch it legs. Hello! I've had a new PC beast for a couple of weeks now: - Ryzen 3900X Gegunio 5950X | 32GB RAM 3800 CL14 | 5700XT | Crosshair VIII Extreme Even a offset of -25mV would cause the CPU to have 100-200MHz lower boost clocks. later you could just try mem timings that are tighter and maybe tweak the RAM voltage a touch, And -14(or -13, dont remember) on the other. 05GHz. New posts Much to my surprise when I went in and tried to tweak the voltages clocks with BPO and the best temps and a work around for the Offset Voltage issue. Edit: Lowered voltage with negative . 35000(for my Ballistix Max)/ VDDG CCD Voltage Control 0. My 5950X has been rebooting a lot recently. 25 full load), 5950X - Lowering SOC Voltage at 0. The scalar is supposed to increase the voltage in most scenarios. Also keep in mind that doing offset voltage will eat into the pbo budget (specifically edc) and you will get lower overall clocks. I have settled on an all-core OC - my go-to value is 4200 with a very small positive offset voltage. Reapply Rebar. I've got a 5950x and +25MHz with -5 won't even load the OS even with positive voltage offset. 38V max when it boosts its nocked about 10 degrees C of the temp and it still boosts to 4. 1V setting. This maximum frequency becomes unattainable a lot sooner with lower voltages than with lower frequencies. Drop EDC to 90 or 100. drea. 05, on standard and offset. Yeah that's how my 5950X was at first too. so it should lower all voltages up to that amount. 075 My 5950x Asus Dark Hero MB 2x16gb g-skill neo Z 3733mhz 14-14-14-28 1. 35GHz, Single core: 5. Undervolting is extremely useful to lower down heat produced by the processor but as you'll come to learn with Ryzen 5000 and PBO you will also get a performance boost. When I try it, my motherboard's 'CPU' LED is lit, 5950X Strange Idle Voltages 1. in Intel 700 & 600 Series 03-04-2024 But that is a big difference. CPU Core Voltage Auto/ CPU SOC Voltage Manual/ -VDDSOC Voltage Override 1. So using negative numbers, you are under-volting and essentially allowing the CPU to boost higher over the range of allowable voltages (up to I thought Curve was a map between voltage and frequency. 5900X can have the weaker cores just disabled. It allowed me to reduce temps while keeping an all-core overclock of 4200 MHz. 885v Vcore offset -0. Share the default pbo settings are using too much voltage, either use curve optimizer or a 5950X -30 all core curve, +200 Mhz offset H150i 360mm AIO Asus X570 Dark Hero 4x8GB DDR4 3600 CL14 Asus Strix OC 3080 Ti EVGA 1600G+ 13xAL120 V2 Uni fans Link You can combine both PBO and offset voltage to tell the VRMs to supply more or less voltage than what the CPU requests; Lower Voltage will lower temps; but is a testing intensive process. 8GHz and a 4. 949/ VDDG IOD Voltage Control 1. 45V GPU PColor 6800xt Red Devil Cpu cooler Be quiet Dark Rock Elite PC case That negative offset is highly dependent on the chip. I don't have an 5950x, running a 5800x. 05 GHz. Asus TUF Gaming B550 PLUS/Ryzen 9 5950x + Arctic Liquid Freezer II 360/some different DDR 3200 16 + 16 GB/GeForce RTX 4080 Making a negative curve will cool your CPU but that allows more room for your 5950x to boost even higher and that is the method behind pbo. Soldato. Set 0. 1 with 71 full load temps with 11168 cr20 28965 cr23 multi core score and 629 cr20 1612 cr23 single core score. 45/4. Disable CSM. 4GHz all-core load. I'm a little worried about these temps, so I want to try to undervolt it so my t In fact while the advertised boost speed of the 5950X is an already impressive 4. That is your fit voltage. Reply reply Top 1% Rank by size . All default voltages apart from RAM. 05V), but that might depend on the workload. First thing I'm gonna do once I replace the CPU is to report here. Computer Type: Desktop GPU: GTX 1060 3GB CPU: RYZEN 9 5950X (Hyper 212 Black, push-pull). , Cinebench, Prime95) to As it seems PBO2 sets the voltage offset already via silicon FIT. 000v Thus, I concluded that if I add +0. 0625V. I’m not Don't use voltage offset. As a consequence, you'll have constant 1. 3. Those temps are fine for Zen3 processors specially under an air cooler. Same boat, can’t figure it out. First off, in the BIOS it’s stating that it’s idling at 50C and the voltage is at 1. The only sure thing is that voltage for a given clock speed is lower. The simple fact is that regardless of which A320 you happening to be testing with you will have throttling due to the VRM's over heating. Click to expand Set CPU Core Voltage to Offset Mode, then set CPU Offset Mode Mark to + and CPU Offset Voltage to 0. Click to expand thanks get about 1. This leads to higher frequencies due to larger margin to the voltage ceiling and increased power budget. (DARK HERO ASUS) Share Add a Comment. Seems a lot of people run into that issue. 1325 mv This kept the 5950x chugging along happily without the mobo slamming 1. In light tasks, like videos games, I have 6/7 cores boosting at 5050mhz and all the other between 4875mhz and 4975mhz. freeagent Conclusions for this system: PBO2 settings are not linear, there is a sweetspot you need to determine empirically 6. Grim5. Originally turning off C-states fixed the issue, but over time the reboots have slowly crept into my normal day to day idle. 38v - 1. After a few days of tinkering I can get +100Mhz to boot into windows and run stable by having CPU voltage -. 5950x Curve Optimizer settings and Cinebench24 Results Offset -30 During Cinebench24 test offset -30 Asus TUF Gaming B550 PLUS/Ryzen 9 5950x + Arctic Liquid Freezer II 360/some different DDR 3200 16 + 16 GB/GeForce RTX 4080 0 Likes Hi, I need to conduct engineering simulations on my 5950x and it runs continuously for weeks. 5k/620 on You can, but there are problems with the two main options, fixed override and negative offset, that won't let you get very far. Leave CPPC Preferred Cores enabled for 5950x. I ended up settled on Clav's method and using these limits 300PPT, 221EDC, 165TDC. The 5950X was an option too but is also more expensive and I don't really need all those cores, nor two golden CCXs. System Name: The Workhorse: Processor: AMD Ryzen R9 5900X: Motherboard: Gigabyte Aorus B550 Pro: But whatever i do the 5950x never boosts past 4. I guess because I lowered my voltage This is a seperate behavior from the 140+ EDC voltage reduction or the super low EDC bug exploit. In Windows, on the latest chipset drivers, the AMD Power Plan is gone. I am a bit confused because every guide I have seen thus far talks about how it is difficult to do much with CO on the 5950X due to the binning. 1 8 of 14 Go to page. There is no 5950x chip with a 1. 2V with occasional "voltage boost" to 1. 38v vcore in bios with LLC during load leveling out at 1. 5 volts to the cpu. I could probably push it higher to +125, or +150 - but the consequences for pushing it too far are quite severe; at +200, I could barely My theory is that it lets you add a voltage offset to the curve which affects what voltage the CPU thinks is required for each frequency. After that, please press [F10] to save the setting. 0125 depending on MB BIOS). 9 GHz, the factory programmed frequency limit is all the way up to 5. 95V in bios ZEN timing reads it as 0. I came to the conclusion that the CPUs were not defective but that the voltages were miscalibrated. You don't want unstable voltages. After setting it to 0. Open comment sort The 5800X did 2033 relatively easy but the 5950X is very difficult to get to 2000. With Curve Ryzen 9 5950X PBO Core Voltage Help overclocking Ryzen 9 5950X PBO Core Voltage Help. 1 GHz, PBO and overclocking. [edit] important: set scalar to X1, and leave it there. 03 volts long term? it will make the vi VId peak above 1. 1-1. Question though, wouldn't a core voltage + offset help stabilze the curve? From general r/overclocking knowledge, leave everything at auto, run p95 small fft avx2 and check the hwinfo svi2 tfn core voltage sensor. My two best cores needed a positive voltage offset on the 3 CPUs. 25V=V+O, where V is voltage and O is offset, i/e 1. New posts. For now, I use Which is why I have my boost offset set to +75, as that maxes my CPU at 4925 Mhz. By Eggicus Roundplumpius May 20, 2023 in CPUs, Motherboards, and Memory. Questions I have relating to the problem: Correct. May your frequencies be high, In a practical example, one core runs at -25 but at higher voltage than another Computer Type: Desktop GPU: RTX 3080 Ti CPU: RYZEN 9 5950x 16 CORE 32 THREADS Motherboard: GIGABYTE X570 Aorus Master rev 1. miffy wiffy Active Member. My particular use case for my 5950x build is to serve as an AOSP build machine, Try dumping the LLC if your CCX are causing problems , if its at level 1 try 3 max might be the dips in voltage. 45 V. Stable at -30 curve optimizer all cores pbo 285-190-280 x10 +200mhz with negative offset voltage -0. Anyway thank My theory is that it lets you add a voltage offset to the curve which affects what voltage the CPU thinks is required for each frequency. 0500V offset. It does keep it from boosting higher than 5. Leave TDC. 25v That should massively improve your temperatures as well. CPU: Ryzen 9 5950X | Motherboard: MSI MEG B550 Unify-X | . 1ish on the other using PBO, I AMD Ryzen 5950X Motherboard Gigabyte Aorus Master v1. Upvote 0 Downvote. Onasi. You can adjust starting and all voltages by introducing "Negative Voltage offset" in BIOS, typically -0. 1v. 125V but my 6 core CPU loses performance at that offset. Hopefully the issue doesn't continue to degrade any further. Record the I’m just a little concerned with the temps and voltages of my new Ryzen 9 5950x. But I assumed your curve would be not impacted by any PBO limits. 05V. g. Turn I'm having issues with my used Ryzen 5950X crashing. , -5 or -10). 050 offset on e-cores 8 core ratio x52 uncore ratio x43 PL1 125W, PL2 175W (all my benches were running at 175) Then on XTU the only thing I changed was processor cache voltage offset from 0 to -50mV. While the speeds will differ, the 5600x should exhibit a similar pattern. Asus ROG Crosshair VIII Dark Hero-Ryzen 5950X-Noctua NH D15 Chromax Black-4x8GB 32Gb GSkill DDR4@3600-Asus TUF RTX 4070ti Super OC-Solidigm P44 Pro 1TB-Solidigm P44 Pro 2TB-Super Flower 1000W Leadex SE Platinum [QUESTION] hit -30 on 5950x many cores, wanting to add a negative global vcore offset. Maybe try tweaking SOC voltages and perhaps try a more aggressive LLC setting too.
