Overclocking Issues

[XboxodX]

I have a ASUS M2N-SLI mobo and a X2 3800+. I can get it to overclock to 2.1ghz without issues, but if I go any higher that that (while bumping up the voltage of course) it becomes unstable. Could the AMD driver be interfering with the overclocking. I ask this because I have the voltage set at, say 1.45v in the bios, but CPU-Z says its running at like 1.3v. PLease help.

BUMP, please I need help.

cpuz will always say a lower voltage then what you set in bios. when under load, the cpu uses more power, if the on board power system cant keep up the voltage sags.

That's weird because in my rig cpuz always reads the vcore much higher than what it is set in BIOS.

Are you playing with your ram at all? Technically with a 100mhz overclock you shouldn't be having a problem but you might want to play around with it and see if it's actually your cpu thats the problem.

Well, I got it to 2.3ghz stable, and I shut it off for the day, but when I came back tonight and I booted it up, it wouldn't post and I have to reboot it to get it to post. Then it started to read at 2ghz in CPU-Z and in the system options menu. I got it stable by lowering the ram's speed, as their is no divider option on this mobo. I don't know what's wrong with it.
