    Your memory is the main prob because with the CPU/memory divider set at 1:1 (400) it's right on its spec'd limit so set the divider for 5:4 (320) and that will get ya further plus make sure that ya have the AGP/PCI buses locked (66/33). Ideally if ya goin' to be serious about overclockin' then go and get ya self some fast timed PC3200 (2-3-2-6) as that will give ya plenty of headroom to work at 1:1. There is no way to unlock the CPU's multiplier though and the FSB is ya only option.

    533 strap does not have a divider option below 1:1 - this means no 5:4, and no 3:2.

    Pick up some PC3200 RAM and it should suit you well for overclocking, also that looks to be a mobo supporting the 800mhz FSB CPU's and one of them at stock will outdo ya 533mhz FSB OC'd.

    Are you really sure your AGP and PCI busses are unlocked?

    I thought they were fixed on that board...
