P5W DH Deluxe - big problem :(
Hi. I have a weird problem with my P5W DH Deluxe, bios 1602. The rest of my setup: E6600 @3.2GHz (8*400), Zalman CNPS9500 LED, 2x1GB Kingston Value 800MHz DDR2, ASUS GF 7950GT 512MB, 2x300GB Seagate 7200.8 @RAID0, SB Audigy 2, Corsair 520W PSU.
When I first set up my rig, I tested it both at default speed and overclocked @3.2 (8*400). For testing I used several hours of 3DMark, Orthos Prime (x2), games, video encoding etc.
It worked perfectly @400*8 for about two months, temps were ok (and still are), never above 62 C under full load.
Now I'm experiencing lockups, usually after about 5-10 minutes under full load, and I have to hit the reset button. After that, the mobo usually won’t boot so I have to turn it off and back on again. It then says something like “overclock failed, enter setup”. If I just try the previous settings in bios (just hit F10 and save) it almost always locks up again, however if I reset the multiplier to 9 (default) it boots at 3.6GHz!!! at the same voltage, and I enter bios setup again, lower the multi to 8, it then boots and works normaly at 3.2 GHz. Until the next time it locks up.
I’ve tried upping voltages without success (temps are not too high, I also tried running with case open), so I’m guessing it has to do something with the multiplier, because it runs normally @ 9x and lower FSB.
It’s like it locks up just because multilpier has been changed from the default value (like the mobo doesn’t “like” that), however I haven’t seen anyone else having such a problem. I must say again, it used to work normally before, at same voltages, temps, settings.
Any ideas?
Thanks.
p.s. would you recommend the latest bios 1707?
