TX750W and Overclocking Failure

Recommended Posts

I have a new build with 12 gig of Corsair Dominator memory which works fine, an Asus P6T mb, an i7-920 overclocked to 4.0ghz, and a TX750 PSU. The problem is that after overclocking everything runs fine until I do a complete shutdown. I can restart from within Win 7 with no problem, but when I startup after the PSU has been off for some time I sometimes get a "overclock failure" message and the system fails to boot up.

 

Someone who is quite experienced and helped overclock my system said it could be the mb is sensing an improper voltage after a complete shutdown when the PSU is cold, but works fine when it is warm. Any suggestions?? Thanks. Tom

Are you able to duplicate the same issues with the CPU running at the default speeds? It's possible that the PSU could be causing an issue when cold booting, but its also just as possible that the issue may lie with the motherboard or graphics card. If you only have the issues when overclocking the CPU, then it may just mean that the overclock is not stable. Have you done any stress testing with the overclocked CPU?

No, I have not had the problem with default settings, only with the various overclock steps up to 4.0. However, when I try to reboot after the failure message, it fails to reboot unless I turn off the PSU button on the back of the PSU. When I do this first, it boots up fine.

 

It was suggested that I try running PRIME 95 and CORE TEMP. Will these test for stability? I am new to all of this. Thanks.
