Have had my q6600 overclocked for about 6 months, no problems, rock stable 3.4 ghz, 8x425, runs prime95 forever and ever no errors on any of the 4 cores, but recently a strange problem has occured..

On rebooting, the motherboard resets the overclock to standard, well 8x 266mhz, like its a failed overclock...

Mobo is a Giga P35 DS4R Rev 2.1

Ram is spot on, 1063 instead of 1066, so should be fine..

prime 95 still runs on all 4 cores no problem, if I shut down and turn on, 90% of the time it works fine...

temps fine, vcore 1.4v watercooled, 38-40 degrees underload..

anyone have any ideas? seen this before?
 
Which BIOS?

Gigabyte are known for releasing the odd BIOS that does that now and again, tho they've been pretty decent recently.
