Well,

I'm venturing into the overclocking world. Before I overclock the 8800gtxs I thought I should get the rig cpus up as high and stable as I can. I've managed to overclock the opterons to 3.17ghz fully stable under all conditions. I will bench mark this weekend. I can get get the clocks up past 3.25ghz, but I notice some weird bahaviors. I clocked back down to 3.2ghz, couldn't find anything wrong, but felt paranoid - so I throttled back to 3.174ghz. No issues. Rock solid.

Since these are dual cores each, I'm concerned that ther are timing issues that I have not taken into account.

How high has anyone managed to get a two socket dual core opteron 2220s to go? How much overhead is there really?

THX in advance.
