WTF!? Im already running Prime95 for 9 hours and 30 minutes without crapping out. I used 14x249 instead of 14x251. Disabled LAN, USB, Serial and COM stuff in BIOS. But only things it gave me was Prime95 not BSODing but erroring. By dropping HTT 2Mhz it's rock solid again

So... How the hell is this possible, my CPU has been stable at 14x251 pretty well when I just got it but now it's not? Though I can live with the 30Mhz drop although if this crap happens again Ill send either the mobo or the CPU back for RMA. Ive a spare Gigabyte 790FX DQ6 mobo which has a broken 4th RAM slot. Been lazy so didnt RMA it yet, but Ill do that soon so I'll have a back up mobo if this happens again.

Thx for the help though, any comments about this strange behaviour is welcome though.
