BSOD without OC

post #1 of 5
Thread Starter 
I have an unusual problem (I think) with my PC.

Bought new July 2011
-Asus P7H55/USB 3
-Intel I5-760 2.8GHz
-Corsair 2*2*2 GB (8GB)
-HDD 300GB
-64 bit Winows 7 home premium

Bought new June 2010
-Zotac 250GTS 1G


If I cold start the PC and miss to do the BIOS OC during startup, I get BSOD in a few minutes.
Sometimes it takes 1 minute, other times it takes 10 minutes, but for sure it will crash.
I can restart it over and over again, with the same problem: BSOD. Don’t even have to start any program. It crashes idling under windows.

If I run memtest86,it reports thousands of errors.


If I go into BIOS and OC, then it works perfect. If I manage to start ASUS utilities I can even OC from
Win and it will work flawless.

I can change BIOS settings so the OC varies from 2.8 up to 3.6GHz and it still works fine that day.
If memtest86 is started again after a OC, no errors are reported.

The problems occur when I restart the next day and miss to OC.
It seems to forget the settings from the last time. MB battery?? Well it do not forget the system clock, so I assume that the battery is OK.

BIOS is flashed with newest verion (even 2 times to be sure).
Have checked Corsair SPD and voltage specs and they recommend 8-8-8-8-24 1,5 V. Tested that with the same bad result. In other words, if I tangle with the settings in BIOS, it crashes. If it is auto OC’ed, everything is fine.

Conclusion;
With OC it works very well and without OC it crashes.. I guess my problems are a bit reverse to most other over clocking freaks. It’s a bit annoying to have to OC every day.

The problems you're having point out to a faulty motherboard. Even if your rig would be 100% stable, the fact you select "auto OC" in the BIOS, works for the current session and forgets the settings until the next day - that's not right. Probably the motherboard sets something incorrectly at stock speed, likely something related to the memory settings; these setings are modified when auto OCing and if you spend enough time you may find out what stabilizes your rig.

I'm not 100% sure so you should gather more informations, others may have other thoughts. Good luck debugging and hopefully you still have warranty for the motherboard.

Check each stick of ram individually and in each slot to try and weed out any bad sticks.
