Has anyone tried "performance upgrade"? It easily yields 4.7Ghz on 100%.
Mine won't post with performance upgrade at 100%
Been doing some digging on the Corsair forums. A few points of note:
1. Apparently Corsair LPX is not the best memory kit to go for on the Z170 - loads of issues - some people not even able to POST at 2133 Mhz on earlier Z170 BIOS versions. Get G.Skill instead!
2. VCCIO max should be 1.2V
3. VSA - max probably should be 1.25V. If you start seeing screen artifacts/tearing you have overcooked it (like I did)
So only hope is a new BIOS version that might improve speeds/stability.
