Horrido Posted August 2, 2005 Posted August 2, 2005 :confused: So without a known good CPU or a known good MB there is no way to tell? If so, I will have to guess on my warrenty return? Quote Share this post Link to post Share on other sites More sharing options...
Dexx Posted August 3, 2005 Posted August 3, 2005 When you say 'bad', do you mean overclocking limit? To see what is limiting your overclock, drop your cpu multiplier down low (eg 7X) and run your memory at half speed (eg 200|100). You should be able to pump the HTT speed way up. If you cant, then its likely that your board is limiting you. Quote Share this post Link to post Share on other sites More sharing options...
Horrido Posted August 3, 2005 Posted August 3, 2005 I'm sorry - that wasnt very clear. By 'bad' I mean dead. My sytem won't post. I'm confident that the PS is good, and am fairly confident the memory is servicable. With only CPU, memory, speaker and the PS hooked up, I get no post or beeps. Standby LED is on, but no dram LED. Pressing power cause a 1/2 sec flash on the keyboard LED, other than that, nothing happens. Fans will not spin up. Initially there was momentary movement of the fans, but this only happens after the board has rested for a while. CMOS has been reset. System was stable for 7 months, then one hot day, died in the middle of a game. So I think either the CPU is defective, or the motherboard.

red930 Posted August 3, 2005 Posted August 3, 2005 Send back the one that's closest to being out of warranty first. This should give you time to get the replacement back for further testing.

I saw this ss: http://valid.x86-secret.com/show_oc?id=27056 Are NF4 boards supposed to hit about that high? Quote Share this post Link to post Share on other sites More sharing options...
