Hi there all, Recently I updated my BIOS to latest (ASRock Phantom Gaming 4) as well as installed the latest Chipset Drivers from AMD (X570). In the BIOS the only things I've changed are to switch on XMP for the RAM and then to switch PBO from "Auto" (default) to "Enabled". I was recently testing out some multithreaded games like Crysis 3 and noticed that the CPU frequency only reached to about 4 GHz rather than say, 4.2 like I expected. Is this normal or something I should be concerned about? Thanks! EDIT: https://www.reddit.com/r/Amd/comments/ckpvhc/3900x_all_core_41_ghz/ Seems like here^^^ they've encountered similar ish performance/frequency -- I don't quite reach 4.1 ghz, but it looks like when I use HWiNFO that it's at maybe between 4 and 4.1 ghz when the CPU is under load in multithreaded games.
