2x256mb Mushkin Black Level 2 PC3200 - in Dual Channel, CPU Inteface Enabled.
200@2-2-2-11, 2.65v (2.6v BIOS - I'm sure it could do it at 2.5v, but for some inexplicable reason, my board has 2.6v as the lowest vdimm setting...)
217@2-2-2-11, 2.75v (2.7v BIOS)
233@2-2-2-11, 2.98v (2.9v BIOS)
235@2-2-2-11, 2.98v (2.9v BIOS)
all memtest stable, except for 235. It starts to error after about an hour in memtest. I'm not sure if it's necessarily the memory or the chipset (mem controller part) that's crapping out. I can't test with dividers to find mem max because the dividers are totally screwed on my board, and result in no post, no matter what divider I use.
