I recently built a new PC and, for the first time in a very long while, I’m using an AMD processor.
So I was curious whether—and how much—it’s possible to optimize it for everyday use.
I read a lot of posts here and watched countless videos, the information and tips were truly very useful.
So I’ll share my results (maybe they won’t seem very impressive to some - but for my current needs they’re sufficient, although I’m open to hearing suggestions on what/how could still be improved).
Let’s start with the RAM. Since I need a large amount of RAM for daily use, I’m using:
Kingston Fury Beast RGB (4x32GB DDR5), originally 5600MHz / CL40 1.25V (XMP Profile 1)
I couldn’t get the memory to run at higher speeds - there were fairly frequent crashes, so I decided to change only the timings, and the results are as follows (photo attached).
P.S. Originally, AIDA64 latency was around 80ns+.
I focused mostly on the primary timings, for the secondary timings I made only a few small adjustments, which can be seen in the ZenTimings screenshot (photo attached).
Next came the CPU. It turned out that AMD doesn’t really require much - just enabling PBO and making small per-core adjustments with negative values (I also set a temperature limit to 90°C and enabled Scalar X1, that’s all).
I used StatusCore software and HWiNFO to measure voltages and fine-tune each core. It turned out that some cores are significantly weaker than others, but overall the result is quite satisfying. Initially I used Ryzen SDT for tuning, and once the system was stable, I entered everything into the BIOS (photo from Ryzen SDT software attached).
I was surprised by how good the CPU’s results were in Cinebench R23 (photo attached).
As for the GPU—there wasn’t much to do here. I found a stable Core Clock +280 and Memory Clock +950 (photo from the 3DMark Steel Nomad benchmark attached).
And of course, before all of this, many hours were spent on system testing:
- Y-Cruncher full test including: BKT, BBP, SFTv4, SNT, SVT, FFTv4, N63, VT3 — 12-hour test, no errors
- MemTest5 (both anta777 Extreme and Ryzen 3D Anta777 tests, 5 hours each) — no errors
- AIDA64 Extreme system test (CPU/FPU/Cache/System memory) — 12-hour test, no errors
OCCT tests:
- (CPU + Memory / Medium data set / Mode: Normal) — 10 hours, no errors
- (CPU + Memory / Large data set / Mode: Extreme) — 8 hours, no errors
- (Memory / 90% / AVX2 / Threads: Auto) — 8 hours, no errors
Just to be safe regarding the GPU, I ran 3DMark Port Royal in a loop for 6 hours, which also completed successfully.
Overall, I’m quite satisfied with the AMD system—everything works fast and smoothly, without hiccups.
System:
- R9 9950X3D
- Gigabyte Aorus Master Elite X870E
- Gigabyte Gaming OC 4090
- Custom loop (3x360 / 46mm radiators)

I’d like to thank those on this Reddit page who share a lot of truly useful information, especially helpful for beginners 🙂
In any case, I’d be happy to hear suggestions—maybe there’s still some nuance I should take into account.
Thank you!
Try to get your RAM to 6000MT with CL32 or even CL34. Then set UCLK=MCLK and FCLK to 2000. Usually that's the minimal latency setup.
Also my CoreCycler detected first error with y-cruncher after 15 hours, and by the 20th hour most of cores had errors. I think it was VT3 and FFTv4 algos.
I tried setting to 6000 , but always crash and no boot , even if I set voltage to 1.3-1.35
Even at CL38?
Yes , but when I remove 2 sticks and only keep 2 (64) , then I can boot up even 6200/cl28
Ah, I've overlooked that it's 4 sticks.
Gonna need crazy vsoc to get 6000+ running
I'm new to all this. Why cinebench 23 and not cinebench 2026?
