*Update* 6/27/06 - I'm now using an OCZ GameXStream 700 watt PSU and I still have the exact same problems. I think my only conclusion now is that this motherboard is either faulty, or Abit is total crap for overclocking. To make a long story short, this mobo won't break 2.6 ghz (stable or otherwise) with ANY multiplier using my opteron 165. This is a proven chip, as stated below, that will easily do 2.7ghz on stock cooling. My CPU voltage doesn't seem to dictate my overclock at all. In fact, unless I bump the voltage on the 1.8V NB and HTT, I can't overclock above 2.2ghz. Abit denied any problems with this motherboard and told me never to overclock.
Are there ANY Abit employees on this forum?

I have an opteron 165 that I had previously in a MSI K8N Neo2 Platinum and it OCed to 2.7ghz without breaking a sweat on air cooling. Now as I installed the AT8 32X, I tried to repeat my overclocking success on this board to NO avail. After playing around with my vcore and realizing that it wasn't doing a darn thing, I got the bright idea of reducing my HTT voltage and see what happens. Keep in mind at this point I'm running 271x9 @ 1.4vcore and 1.4 HTT voltage. I bumped the HTT down to 1.35V, no post. Ok, well then I changed my FSB frequency from 271 to 255 at 1.3V HTT, it posts no problem. After playing around and making sure I wasn't imagining things, its very clear that the HTT voltage at 1.4 will only allow my FSB to be around 270. I tried using uguru in windows and its an instant lockup. I have experience OCing and I have made sure my ram is not part of the equation, its at DDR200 and 2.5-3-3-7 timings, its rated for 2-3-2-6 at DDR400... Anyhow, any help would be appriciated, I just need to figure out if this is defective or if a bios update will solve my problem.
