My Haswell Setup

[Lloyd_mcse]

So I tried prime 95 last night, on 4.2 and it crashed with in 3 minutes every time. The error was CLOCK_WATCHDOG_TIMEOUT which I am led to believe is an error related to the CPU?

I tried it again with a higher voltage and it lasted for 10 minutes so I left it overnight. Woke this am and it had crashed.

When it was on 4.3 with low ram it went through all night without issue. As in out of the box before anything was changed.

So it was stable at 4GHz and the RAM at 1800.
Try 4.2Ghz with the RAM at 1600MHz for the moment. And leave the voltage at 1.200v CPU Core Voltage.

EDIT: I added a screenshot of CPU-Z to My Haswell OC thread
