Up to you on whether to stay at 400 or drop back to 390. I really don't know if the differences matter much in terms of noticeable performance. It's 80Hz on the CPU and 20Hz on the RAM.....2.5% Like I said before, I'd leave it at 400MHz and +50mV because all the frequency numbers are more "even"
Nice to see that under "typical" load (Witcher 3) your temps are at 62C. That wouldn't concern me at all. Keep in mind, IBT or Prime95 are "power virus" programs that stress your system like a Folding program would. That kind of load/heat is not typical in everyday use.
I also just noticed that your CPU fan is at 1650rpm in all your screenshots. Is that 100% fan speed or?
Well, VCORE OFFSET values options are: AUTO, 0, 50, 100, 150, so 50mV is the lowest increase value available.
As for the CPU fan, I checked both specs and BIOS...looks like 1650RPM is the highest rotation value available.

Otherwise the next step up (150 mW) only causes one cores temperature to jump 78c, as long as all 4 cores stay under 85c I wouldn't worry. Every so often check the temperatures make sure everything is a-ok (dust build-up/fan spinning.)
Temperatures look fine to me for your recent post.
All in all, things seems to run well and fast...it's good to know temperatures are acceptable for you both...so I guess I'll keep my PC like this, and I'll keep its temperatures under control, as you said.
Once again, I want to express my sincere gratitude to you both. I really don't know how I would have done without your help!
