Ive got an Opteron 170 CPU in my system. See my sig for the rest of my system specs. I just recently got into overclocking so I'm no expert on the subject.
Heres what is happening. I have been running my CPU at 2.5GHz. At stock the CPU runs at 2.0GHz. I've also been running the RAM on a 1:1 divider at 250MHz. Aside from a little excess heat everything has been good to go. Although I never got around to running memtest, the CPU ran stable for 10 hours of Prime95 with small FTT's. I ran two instances of Prime95 with affinity set for each instance to each core. No problems for 10 hours.
Anyway, I also had a TV card in my PC. I just built this PC about 2 weeks ago and everything in it is new including the TV card. I went to bed last night and everything was good. This morning I get up and the computer will start, (fans running, CCFL's lit) but I get no video, no POST, no beep codes, no HDD activity, no nothing except for fans, CCFL's, and a few seconds of activity on the XMS RAM LED's. Finally after trying various things to fix the problem including reseting the BIOS through the jumper, and removing and exchaning the RAM modules I start taking things out. After taking the TV card out, the PC boots right up, (albiet at default speeds because I reset the BIOS). I put the TV card in another one of my computers and the other computer did the same thing as this one. No video, no POST, ETC.
So next I reboot, go into the BIOS and reconfigure the BIOS for my OC"d settings. After saving the BIOS settings and rebooting, Windows will only make it to the XP logo screen and goes into an endless reboot in which it reboots everytime it gets to the XP logo screen. I go back into the BIOS and put everything back to default and the PC boots into Windows fine. Why won't the PC overclock anymore?
Since I have an A8N32-SLI board I set the overclocking options in the BIOS to 10% pushing the CPU to only 2.2GHz. The memory also got pushed to 220MHz but stayed at its default timings of 2-3-2-6 instead of my OC'd timings of 2.5-3-2-7. With the 10% overclocking option on, Windows boots fine. But again, at my previous OC settings I can't get Windows to boot.
So what do you think happened? Overnight my TV card dies and now the PC won't OC to it's previous settings. The PC was off all night so It's not like it got zapped or anything. Its on a surge protector and I turn the PSU completely off so even the board isn't getting juice.
Any ideas? I even did a clean reinstall of Windows but that didn't help. It still wont OC to its previous state. It's my understanding that this CPU should be able to get 2.8 or even more so 2.5 isn't THAT extreme of an OC. Is it typical for a CPU to OC for a while and then poop out like this? I don't have the slightest idea of what happened.
Any comments are welcomed. Thanks in advance.
