Somehow my super stable tune got the best score with-in same HW (very careful and safe side tune!)
Tune:
ASRock b850i ITX (sf850 2025) 1 case fan.
AMD 7800x3d
• no preset, PBO – Advance, 85c, CO -30 all beside core2 -20!
• bclk 102.0 (sets Fclk 2040mhz, Uclk 3060mhz, mem clock 3060mhz=6120mts)
• CPU_SOC up .02 so 1.22v just to be safe (should not be needed)
• iGPU, spectrum, safe boot and other useless functions off to reduce latency and background load
ASRock 9070xt Steel Legend (Hynix mem)
• -75mv, 2718mhz Fast, +6% (+10% drops fps abit)
Corsair Vengeance 2*16gb cl30-36-36-76 6000mts
• Expo0 sets above values, before bclk
——————————
All bench marks passed
– Cinabench 18998
– prime95, Blend
– OCCT CPU & CPU+RAM (AVx512 and AVX2 and SSE)
– CoreCycler Small FFT, SSE 2+h and avx512 large FFT 3h
– Y-cruncher over night.

My system seems to be not pushed to the limit
– bclk could def go to 103, if PCIe clock is decoupled? So we get ram 6180mts=3090mhz and Uclk too
-
Fclk can be manually set to 2033 safely, so that we get 2033*1,03=2.094mhz
-
CO can def be pushed to -33 or -35 on best 2-3 cores and likely -23 or -25 on the worst one core!
-
2/3/3 ratio fully maintained and locked
But I’m very happy.
• Warzone 4k Extreme Native 100fps locked, 10ms stable (+/-0.1ms), cpu 63c hot spot 35-40% util! gpu 85–95% util 48c, hot spot 65-71c, and vram 78-80c!!
Love it! If you see any mistakes or better ways to tune system, please tell me, I’m pretty novice
