Yeah I can around 1.48v VCC Sense (1.43-1.44v actual) for 5.3Ghz. Temps in the mid 90's tho.. can't even touch Prime95 or it'll throttle over 105c. I tested it with realbench and some gaming and it doesn't WHEA error or crash but temps are so high I can't run it 24/7 so that's why I'm going direct die. Even 5.2 @ 1.41v (actual 1.35-1.36v) is pushing it a lot with AVX Prime going to 95-98c and some games pushing well over 70c which I don't like as it's winter and ambient in the summer can get way way higher even with my A/C.Can you pass r15 without cpu cache errors @ 5.3ghz on ur current 10900kf, if so how much voltage does it take? I have tested 2 newer 10900ks and they were both terrible. One couldn't pass r15 @ 5.2ghz without errors with 1.4vs (1.36 actual). The other cpu was barely any better. It seems like its alot harder now to get a decent bin.
That whole socket sense we talked about is nice but there's a reason it stayed cooler, it also is impossible to stabilize for some reason. I have been having so many weird crashes and BSOD's even that I gave up on it and went back to VCC Sense cause at least there I can trust that it's solid.
