Everything is at stock for now (except see below), no OC yet.
I was having failures with P95 with stock settings after 3 - 5 minutes. So I changed CPU Margin Enhancement from Optimized to Performance, and after that P95 worked for hours with no problems. BTW I was having zero other failures -- games working fine (WOW, Assassin's Creed, Mass Effect), etc. No BSODs at all before or after I changed CPU Margin Enhancement. I've only been running all the test suites to establish baseline before OC'ing.
