P.S. if it freezes on idle ,try different LLC or disable C3 and 6, if it doesn't freeze under default settings than it's a bad OC
I have already said like 10 times. I get random freezes with UD5H + 2500k that don't occur while stress testing. It will pass 20 runs of IBT and Prime at 4.5ghz, then just random out of nowhere, the system will freeze once or twice a day. I set the system to stock speed and load BIOS defaults and it still happens. That's all there is to say about BIOS settings.
Like I previously mentioned, the system normally runs with a DPC latency of 4:
Then out of nowhere, once an hour or something, I get some 2400DPC spike as outlined in the post below, so there are clearly some problems with 2500k and this board right now. I never had any DPC spikes on my Asus i5-760 build, and all of the components from it were used on this except CPU + motherboard.

BTW IBT isn't as strong as Prime95 is for SB/IB You can IBT for 50 loops and then try prime95 and get done within the first 10minutes.
Now don't set anything after you load optimized defaults, run everything at stock, even memory and test again. If you still have issues and your PSU isn't messed up, then RMA the board.
I'm not going to say it's "impossible" for there to be a PSU issue, but it's highly unlikely when I transplanted this PSU from an i5-760 build that worked flawlessly gaming for hours 1 day before putting it in this UD5H. The freeze also occurs at random, sometimes at load, sometimes while just browsing the web. It doesn't occur while doing 20 runs of IBT so it seems even less likely to be a PSU issue.
