I seem to have a very good 5820k on a X99 deluxe, can boot and windows stable at 4.9-5ghz and games for hours at 4.8ghz (even IBT stable for 10 passes of very high) but it crashes in realbench and x264 stress test at 4.7ghz. This is a problem for me because I upgraded largely to do x264 encoding lol.
I keep getting 124 and 101 BSODs which are usually vcore, but I truly don't believe it is because there is no difference between 1.32 and 1.4v for stability. Maybe a little more vcore helps slightly. Here are my settings that I cannot get stable:
4.7ghz
1.3 - 1.4v
PCHIO 1.625
VCCIO 1.2
CPU Cache 1.23125
pch core 1.2
vccio cpu 1.2
CPU Input voltage: 2.15
Optimized cpu phase power control
140% cpu current capability
Auto cpu vrm switching frequency
CPU llc 9
Have tried with LLC on auto as well as manually levels 8 and 9, seems to make no difference.
Temps are great, have a nice water setup. Never hits 80c in x264 or realbench.
VRM temps are getting hot, around 78-80c.
I am totally out of ideas, is it the board? Should I return it and get the Rampage? I really want 4.8ghz stable for 24/7 use.
