Hi
I have a ROG STRIX X670E-E, AMD 7950X CPU with newest 1602 BIOS, 192GB RAM running Debian Linux - doing "number-crunching" (large scale map data processing). Everything runs stable and smooth.
Now, as I already have this nice motherboard, I decided to give "AI overclocking" a try, but my experience was not really satisfying. I used my own application as benchmark (runs 5h: first 1.5 h it is running on 1 core, the rest is multi-core capable and pushes to 100% CPU for 3.5 h, all 16 cores are maxed out).
Now as a baseline (before enabling AI overclock), I got a runtime of 299 minutes. Temperature of the CPU was around 95°C so I guess I ran into thermal throttling.
After I enabled AI and run the benchmark several times (always rebooted to BIOS after each try), the runtime of my benchmark INCREASED - it is always around 310 - 315 minutes now - so 5% slower. Temperature is lower, approx. 85°C now - so there is still some thermal headroom, I guess.
Also the IDLE power (= running Linux, CPU load is almost 0%) was 47W before, now it is 62W.
My questions:
- Has anyone also used Linux - or is AI overclocking a Windows only thing?
- Do I have to go into BIOS now-and-then, so new settings/learning get applied? Or is it just "tuning" in the background if enabled?
- Can I still change other parameters in overclocking (e.g. enabling C-States or Medium-Load-Boostit) or will that disable AI Overclocking?
- Why is the temperature of the CPU lower now, I like to get to the 95°C limit? (My fan setup reached 153 points in BIOS)
- Why is IDLE power jumping from 47W to 62W - does this AI feature use so much processing power internally? Or what is using that power?
