Less heat and fan noise decreased. 1. Standard risk/benefit caveats apply, the difference between a 3. The Ryzen parts tend to be a bit cheaper, with slightly lower CPU performance (~10%), but a much better iGPU (~50%). Undervolting won't affect your turbo boost performance. Hey, I just got a RBS 2018, and I was wondering if anyone has settings that they can share with me for ThrottleStop. Throttlestop helps though!

However, I noticed that I did not have any thermal throttling at all (except for 5-10 seconds after temps reach 90+ C under stress test) and that it was purely power limit throttling. My best multicore cinebench R15 score with these undervolts is 638, up from 530~ I've used phoronix test suite asmfish and the results were staggering, below show an asmfish score without undervolting, all cores where utilized under ~2000MHZ clock-rate,score was 7259033 Using the following intel-undervolt conf I was able to run all of the asmfish test without problems, and all cores gained extra 650MHZ on ~2650MHZ, here Dec 12, 2018 · After undervolting, I only have TDP throttling.
