looking forward to seeing what settings you change omnidragon.
still struggling here with my UD4...
It got through last night, but I powered down and re-added my capture card and it's unstable again. removed the card and it's still unstable. The only other thing I did was install a 3rd party firewall - and yes I've tried removing that too....
At this stage I'm convinced it must be the board/BIOS itself... I've put everything into my 1366 system and it's stable (although I can't quite put in exact same config).
Also had issues with F7B - for some reason after a few resets I will get a BIOS checksum error and be pushed back to F3. So have stopped at F6 for now.
I've run memtest twice on every DIMM stick, once separately, and then 1 by one adding to the system.
I've disabled LAN and Audio in the BIOD to no avail - they are both now back on so at least I can enjoy them when the system doesn't idle.
I've also disabled Turbo Mode, USB3, eSata3 and removed some of the wake events.
Is very frustrating - only happens when it's idle - and nothing in the logs.
