figured out the mem divider issue. I had subtimings manually adjusted and board likes them left to auto, at least for my memory.

I can run now 450fsb at 1:1 memory default mch, fsb, pci-x voltages, and I think default cpu voltage. However anything past that gets hard. 475 posts bios but nothing past. Even 6x multi. I took off NB heatsink and applied paste, no help.

Going to try some 6300 cpus I have lying around. Think I'm at cpu limit .
