Can anyone advise on if setting cpu power phase control on an ASUS mobo from 'standard' to 'optimized' would help with system freezes under virtually no load to light/moderate loads? My 3570k seems to have become very slightly unstable over the last week or two without any other system changes. I have tried increasing the offset by +0.035 without success. The freezes only seem to happen under virtually no load to light/moderate load and not under heavy load. I'm currently at 4.3ghz with a max voltage using offset mode of 1.248v. So far changing from standard to optimized seems to have worked although I'm not convinced. LLC is set on 50% high, PLL overvoltage is disabled, all c states are enabled (tried disabling all bar c1 to no avail) and cpu current capability is 110%. I'm convinced it's the cpu as I had the exact same issue previously when the offset wasn't quite high enough. I thought this wouldn't be an issue as perhaps the cpu was wearing in after a year and so maybe just a +0.005-0.010 increase in offset would be needed - no luck with this. The freezes seem completely random and have occurred in firefox, on just the desktop, l4d2, ac4 menu screen and once in bf4 with virtually nothing on screen so I again suspect moderate load.
