Ryzen master curve optimizer per core or all cores

Ryzen master curve optimizer per core or all cores. We also had intended to test with ASUS’s automatic overclocking in AI Suite 3, but it’s a relatively inelegant tool by comparison that just set all cores to 4. Ryzen 7 7800X3D B650 GAMING X AX V2 G. However, when using this script, and with +0 MHz Boost Override, I needed to go down to -9 on one core to have it run stable (on the other hand, another core was Aug 5, 2021 · Thanks for the clarification I thought the adjustments, per core or per entire curve, were mV adjustments. The primary functionality of this feature is to tune the AVFS curve of the entire CPU or specific cores of the CPU such that the tuning overrides the fixed curves that they are fused with, resulting in an increased CPU performance. Try testing the undervolt in Windows with stress tests, or monitoring idle temperature using HWiNFO to see if the results are worthwhile. My setup: Ryzen 7 7800X3D AsRock B650M Pro RS 2x24GB G. After rebooting, I'm sitting here trying to find some way to run the Stress Test that I know Ryzen Master has. After finishing the CO Optimizer, it set all my cores to -20, but once again, it bricked my system after restarting it, thanks Ryzen Master! I was really curious to see what is bricking it, so I went it, and Yolo-ed CCD0 to -30 per core. Tested in cinebench R23. Q: The core I select in Ryzen Master isn't the same as here! A: Yes, Ryzen Master starts it's core numbering with 1. I don't think tuning curve optimizer on a single core basis is a great method for finding a stable curve. 2.

Currently testing it is looking good so far. Rinse and repeat (hope you get the idea). " This button means that any change to one core changes them all to the same value. Potential Performance Boost: Optimized voltage can result in higher boost clock speeds. If you applied -10 in core optimizer, you are adjusting the curve by negative 10mV. If you use -30 on all cores and then do +200 you'll get crashes. If you were to cool the CPU with chilled water (-5C or so), you would probably see lower temperatures from tweaking curve optimizer. 204V offset (min selection) on the BIOS. g. Per-core CO tuning was better than all-core. and now I have changed to -30 all core, with 50Mhzboost, PBO limit motherboard (not done any fine tuning (per core setting with lower value for best core e. 5 MHz, an Fmax boost override of -200, and a per-core Curve Optimizer ranging from +10 on Cores 2, 3, 5, 6 to +25 on core 0.

Usually your 'best core' and 'second best core' as shown by Ryzen Master will need to have less negative curve applied, and the rest of the cores can have less voltage (so higher negative curve optimizer value). 0, agesa 1. Hi all, sorry if this is expected behaviour but doesn't seem to make sense to me. 0的Curve，但FFTSize模式无论是用默认的Huge还是隔壁lacisess和摸摸卡大佬推荐的Heavy、Large模式，都能在Curve Per Core Negative 21、18、23、21、14、14，FFT=Auto模式下跑完10轮而 then i enabled all cores in CCD0 with curve value above for every core and run CPU SHA3 and get bsod immediately. Only single-core boost reaches 4. Clicked on Core Optimizer section, clicked on Per Core, clicked on Start Optimizing. Chose to test per-core and after a hour of testing it came back with a -30 on all six cores. In this case, cores 04 and 06 were the best. Each core has multiple V/F curves that vary depending on load on the CPU. 0 GHz, it would now request 1. I will show you the BIOS configuration in a minute. Focus on effective clocks. Set the CPU affinity and test each core individually. 8. So I've gone into the BIOS and set the curve optimizer to -25mv on 4 of the cores and -30mv on the two strongest cores. It's too bad PBO2 doesn't have a per-core MHz limit, because it seems like raising the curve primarily serves to prevent single-threaded workloads from clocking too high. 9. It took about an hour for my 5600X so may take longer for higher core Sep 8, 2024 · Per-Core or All-Core Optimization: You can apply optimization to individual cores or your entire CPU for granular or blanket adjustments.

Adjusting all cores does work and have a measurable effect but now i wanna go deeper in the topic and set up a "per core" setting. My PC rebooted and Ryzen Master came back up and started tuning CO. So my question is, is it normal that my best core can handle such a low negative offset, lower than the "regular" cores? Hey, I just wanted to share a quick overview over the results I got, with like no effort at all. This is a beginner's guide updated with the latest techniques. ) just maxed out CO in negative and reduced boost. The result was, that each core was set to -30 and that seems to be the lowest undervolt possible. Tests needed to properly validate per core PBO are described in the "guide". Curve Optimizer will tweak the voltage/frequency curve so that the processor can run at a higher frequency at the same voltage. After all 6 tested, ran all 6 cores with affinity for 30 minutes to verify high-heat stability. Ryzen Master per-core curve optimizer recommended -30 for all cores. 49v. I ran each core against OCCT with 2 threads, and affinity to both threads for a single core at a time. Best tunes comes with default settings and scalar off. I tried a quick and dirty all-core -18 and I noticed some instability (mainly in Hogwarts Legacy but also in Genshin) so I decided to try and use Ryzen Master and its auto curve optimizer.

AMD Ryzen Master Advanced View provides for up to four profiles to store custom user-defined configurations for both the Ryzen™ CPU, integrated Radeon™ graphics and DDR4 memory. Lately I've been toying up with PBO2 with my 5600X. The nature of how curve optimizer works means that you are more likely to have instability when your system is idle than at full load (even when testing only one core). Only AMD knows why, it's not the industry standard. Maybe it's geared towards AGESA 1. Ryzen master just overwrites the settings in bios so I would disable auto OC (and everything else to default) in master before changing BIOS settings Right now Ryzen master doesn’t support curve optimizer This isn’t manual all-core OC, all this is doing is undervolting and raising the max boost speed so that the CPU decides to run at higher clock speeds while managing its voltage. 0) : Amd (reddit.

The reason you do curve optimizer is because at stock from factory, AMD has a specific V/F curve that basically fits all cores, despite some being better than others, and by using per core you can tune this curve for each core specifically. The all-core setting is only as good as your worst core, which is typically the “preferred” cores per Ryzen Master. If Ryzen Master hits -30 for your cores, you’ve got a golden chip. "Core 6 (CPU 12)" respectively means it's running on the 7th core (remember, zero-based!) and 13th virtual CPU. Choose all cores or per core and click "Start Optomizing". So I set them all to -6 and started from there. Why do I still use Offset Undervolt? I cant do - 30 all core curve optimizer, crashes. All core said to set to -22, per core gave me -25 on all except for core 2 at -21 (2nd best core).
