Hey there, friends. I just finished setting up my brand new Ryzen 7900X on the Asus X670E-F motherboard and ran stability tests with everything set to default. The only change was enabling XMP/DOCP for RAM in Asus Bios. The system performed well, scoring solid results in Aida64, Cinebench, and Prime95 over an hour on Windows 11 22H2. I also ran the passmark memory tester and Windows memory diagnostic—both passed without issues.

I’ve been trying to tweak the Asus Enhancement settings inside Precision Boost Overdrive, but Cinebench keeps crashing when I hit the thermal limits at 70°C, 80°C, or 90°C. The curve optimizer with PPT 180W and aggressive negative cycling didn’t help either. I’ve also tested different BIOS versions and chipset drivers, but the problem persists.

Have someone with more experience a look? I’m pretty confident I got one of the best 7900X builds possible. Here’s the full spec list: AMD Ryzen 7900X (IGPU), Thermalright Peerless Assassin 120 SE (air cooler), Asus X670E-F, Corsair Vengeance RGB RAM at 6000MHz (non-Expo), Asus TUF ATX 3.0, 1000W PSU, WD Black SN850X.

For the Ryzen 7000 series, the ideal operating temperature during boost is around 95°C. It's best to avoid setting a strict thermal cap and let the processor manage its own temperatures naturally.

It's possible you're relying on an air cooler, which might prevent you from achieving a negative curve for better CPU cooling. Your aim is to reach 180 watts while keeping temperatures at 85°C. The older AMD Athlon X2 5000 models were simpler, but now Intel's 6700K series is more complex—making it harder to understand their performance characteristics.
