Overclock resets itself on my P965-DS3P?

Been running quite happily at 400 x 8, vcore at 1.3v, RAM voltage +0.05 but off late it just randomly seems to reset the FSB to 266, no other real indication in terms of boot-up weirdness. I originally primed the above for a couple of hours no probs. Primed it last night for an hour and no errors, didn't have time to prime for longer.

Have increased the RAM voltage to +0.1, also set MCH and FSB to +0.05 to see if it improves things but has anybody else had similar where stable suddenly becomes unstable?

EDIT: Just did a proper search and found that others have had similar problems so have a few things to try tonight, also forgot to mention that I also upped the vCore to 1.316 or something around that range. Will know when I get back home today if things are OK.

EDIT2: Thought it might have been my aged PSU, used to run the rig off an Enermax 430w jobbie but recently updated that to a Corsair HX520.

not sure if this is the same issue i had on P35 DS3R, but the bios wouldnt hold the OC even tho it said enabled in BIOS. Was fixed by a CMOS reset and reconfiguring BIOS after.

Thanks for the input, I'll also give that a go tonight.

Quick update, looks like the following has fixed it as it's still running at 3.2:
