OC Problems


In Runtime
Just recently I was OC'ing my processor, an AMD 4600+, and I started getting BSOD's. That's the summed up version.

I have OC'd my processor many times, through the Ai Booster program my mobo came with, an A8N-SLI Premium, and through the bios, too. Here's my problem though, I have never had any problems with ocing through the Ai Booster, it'll go to 2640, from 2400. However, just recently when I OC'd through the bios, I got my first ever BSOD in XP Home.

I OC'd it to 2600, which was perfectly stable, then 2650, which seemed stable at the time. I finally got it to 2750 after much tweaking with the settings, when I got my first BSOD. I lowered it to 2700 and it was up and running for a while. Played CSS for a while before I got yet another BSOD. I lowered it a few more times gradually, and yes, more BSOD's. I'm sitting at 2672 at the moment, and all seems well. The BSOD's aren't a hug deal, they happen at random times during gameplay, but I want to find out how to get a stable OC.

Sorry for this, but here's some CPU-Z info.

Why exactly am I getting BSOD's? I'm definitely not a pro overclocker, though I have done research. Anything I'm just missing? Any useful tips? Thanks in advance.

If you need any more info just ask.


Fully Optimized
im wondering that myself. i have a 5600+ and i cant get any higher than about 3.150GHz without BSOD's

Some games just do not cope well with overclocked systems, even if it's stable under stability testing.

What you really should do after overclocking though is a stability test. Run Prime95, and if it doesn't crash after 10+ hours, you're good. If it does, your VCore is either too high or low depending on your temperatures, which you should be monitoring carefully.
