7800x3d curve optimizer reddit What am I doing wrong? I'm We learnt this back when Curve Optimizer came out for Ryzen 5000. I previously used DOCP I with no custom settings beyond that except maybe a tune down from 6200 MHz to 6000 MHz. with 102mhz eclk and curve optimizer -16 -15 -25 -22 -19 -20 -23 -31 i get 18. Each step is around 3-5mV. I can confirm, curve optimizer set all core at -39 and after gaming sessions my pc just randomly restarts. With the advanced boost curves these CPU's have, manual voltage adjustments are only really useful for static manual clocks. After bios reset i set -10 for negative curve and temps going down and boost is almost 200Mhz up Get the Reddit app Scan this QR code to download the app now 7800x3d Curve Optimizer Clock Stretching . 8 all core, but it'll be doing that at thermal throttling. Since using Buildzoid's settings, I've been able to push the Curve Optimizer offsets much further (everything was previously about 5-10 points lower) with less instability. Maybe a bug since I set it to optimize per core and it took 1 hrso it had to be doing something with that hour . 10. You can however play with Curve Optimizer (CO), and set a negative offset for the cores. Cooler: Dark Rock Pro 4 - fan curve set to Standard Case: Pure Base 500 FX MB: Asrock X670E Steel Legend Results: CO disabled: 17473 points, max. After you've set it to -20, go to Windows and run Cinebench or something. This means that the limited amount of voltage available to the 7800X3D is maximised, and the voltage won't droop under load. 5ns latency (which is sensitive to background apps, make sure everything is closed and don't even move PBO, then go to Curve Optimizer (or C. Coincidentally, I just took at look at my per core curve optimizer settings for my 5800x. Help (CPU) Hello good people of reddit. Positive CO is an overvolt, and negative CO is an undervolt. I don't understand how this curve works on CCD0 with cache. ), then select something like "all cores", and then select "negative" and set it to -20 at first. 1, boost clocks 4. Latest version missing auto-detect Curve Optimizer feature for 7800X3D (Start Optimizing button replaced by Validate Offset) Reverted to version 2. I would prefer to keep things stock clocks or better. Many people would get stable under heavy loads in Prime95 etc, but then have crashing when left idle. 5k cinebench multi, same single core as you 1850-1860. To test CO properly, you must do it single threaded. I bought a 7800x3d, and so far I really enjoy it. Imo, a few hours is nowhere near enough to properly test Curve Optimizer settings. very impressive, just wish it would persist after reboot because I'm gonna forget. my ram is a bit better, 6200mhz, 380 trfc, 36 on secondaries, 20 tfaw, 66032 97205 65739 read/write/copy, 58. Planning to try again at a lesser offset. I did some quick testing and found some interesting info I thought I would share. Trying to finish refining the curve optimizer on a 7800x3D 7800X3d and curve optimizer issue Hello, I come to you because I encounter a problem with the PBO and the curve optimizer on my 7800X3D, in fact as soon as I modify the curve optimizer to put it at -10 (low value) on all core, the system is unstable and cinebench 2024 crashes, windows is not stable either. After disablimg curve optimizer everything is stable. To grossly oversimplify, it is like an adaptive voltage offset that scales with the power requested. All the configuration here has been tested, over 168 hours on OCCT Prime95 and AIDA64 Core 0 = -40 (Rank 5 Core) Core 1*= -40 (Rank 1 Core) Core 2= -31 ( Rank 4 Core) Core 3**= -31(Rank 2 Core) Core 4 = -24 ( Rank 7 Core) Core 5 = -30 (Rank 3 Core) Core 6 = -31 (Rank 8 Core) Core 7 = -31 7800x3D Curve Optimiser tips Just upgraded to a 7800x3d and I'm blown away by this cpu's efficiency and perf uplift from my 5800x. 2) Activate PBO. Negative will decrease temperatures and positive will increase them. Basically curious how high the negatives can go on the best cores. With a -30 offset it'll do 4. Windows event viewer indicates a Kernel-Power issue, however PSM is not the issue here. Ryzen Master provided the following values which were ridiculously low (-45 to -49). . I also believe it's disabled for x3d CPU's. Pbo curve settings in the negative reduce the power draw that each core can receive when they demand power. wow thanks, curve optimizer does well. I'm trying to set PBO + curve optimizer and coming from a 5900x and reading a lot of guides, it looks like best cores should not be able to have lower negative offset than the other ones. Aug 7, 2024 · My stock CB score is 18300. Curve optimizer set at -20mV resolves this, however I find it concerning the stock config raises OCCT issues on Core #6 that go away after setting the curve. I lost 10c not only in all core cinebench but also in cyberpunk and new world. I did what the other poster did and started with -30 on all cores for my 7800x3d. 2. -30 seems to be considered "winning" the silicon lottery but how far can it go? Do you care about 1000 points in Cinebench at the cost of stability in games? Go curve optimizer -30 You're better off doing memory overclocking on the 7800X3D, and you're not going to get more than 5% in most cases from that either. This allows the cores to run cooler with less power input, which ironically gives them more thermal headroom to boost higher with lower temps. Also for the most stable Curve optimizer vaIues I would strongly recommend using Ryzen Master's curve optimizer scan per core. You can manually adjust settings if you wish after but let it do it's thing and set the values in your Bios. When you add those two values together, they give you your PBO offset. Couldn Try reset bios. I have a 5900x but what works very well for me is using Ryzen Master as it lets you do the tweaking on the fly. O. Oct 27, 2024 · Curve Optimizer tunes the CPU's voltage/frequency curve, if you decide to adjust it you should also be prepared to run a slew of stress tests to prevent random reboots caused by instability. 7800X3D Curve Optimizer . Hi, When im running a -30 curve optimizer on my 7800X3D, i get Cinebench r32 scores in the 17K', and when i bump it up to something like -15 or stock, im in the low 18K's. 8 GHZ So I've been wondering what kind of returns curve optimizer gets with the 7800x3D, as the artificially low max clock speeds limit it a bit compared to the non-3D parts. There's enough guides on YT for this. I set -25 negative curve for every core and +200Mhz positive boost and no difference. In my case, that is "39". and it's all -30. 7900x3d btw. I started messing around in curve optimizer because my 7800x3d doesn't seem to really be boosting single core at all above multi core, and by default was doing like 4. Under "Curve Optimizer" change the sign to "Negative" and then you should apply as high a number as is stable. Just performed some tests on my 7800x3d and i wanted to share some results from Cinebench. In my case that is "39". The performance boost from curve optimizer is most likely in the 2-3% range, upper end is 5% May 5, 2023 · 1) Max out the LLC for your CPU Vcore. I've tried -25, -30 but those are unstable. Max out the LLC for your CPU Vcore. Here is my configuration in bios for the curve optimizer. It will take a while to go, but you'll end up with values in the CO All Core Value and Difference Offset Value. Test between each change, rinse repeat until you're content. Left it like this: Go to Advanced View, Curve Optimizer on the side, then set Curve Optimizer Control to All Cores and then click Start Optimizing. Activate PBO. 3) Under "Curve Optimizer" change the sign to "Negative" and then you should apply as high a number as is stable. Point 2 might get you better all-core values. Hello ive had my 7800x3D for like 6 months now and ive been running curve optimizer -30 all cores since that was what pretty mutch everyone recommended, everything has been running well with zero issues but now all of a sudden ive been getting crashes to deskop in the games i currently play (rust/GZW) after playing around with it -25 all cores seems to be fine. 2367 and ran the auto-optimizer Many paperclip jump-starts later, I realized it was a waste of time. Decided tested curve like these 0-0-0-0-0-0-0-28 etc every core but cpu sha3 not getting bsod, then i decided increase curve by 1 in last core (7) and test cpu sha3 and overall i passed 100 times cpu sha3 without bsod with value on last core -13. 6 on both single and multi-core. Been messing around with CO try to lowers the temps and gain some more efficiency but I'm finding the cores vary drastically what they can handle without throwing WHEA errors etc. Using -15 on CO yields me the same score. I have similiar problem with 5700G. It's stable and good enough for me. Also the curve optimizer has way more effect on temps of my 5800x3d than my 5800X ever did. Apr 29, 2024 · THEN and ONLY THEN you can start OC'ing, using the curve optimizer, RAM EXPO settings etc running stability tests all along and making sure you don't get performance regression. Been gradually learning/tuning my new PC since I built it over the past few weeks part by part. temperature (c): 88. This means that the limited amount of voltage available to the 7800X3D is maximised and the voltage won't droop under load. How to test curve optimizer undervolt on 7800x3d? Help (CPU) How should i test the 7800x3d? i do not know how to setup prime 95 or corecycler,i just set a temperature limit to 80 and -30 pbo + amd expo on,i seem to be crashing pubg for example to desktop,3dmark timespy test and cinebench can run forever x670e tomahawk msi board List your curve optimizer gold core negative offsets. rvsjy mngf zsgiv jatv myfgxe dvfk zaayd uwjwcl bmn spdpn
