ok, now it sees CPU 2 on boot, but says it has an error so it wont initialize it.

put CPU 2 in slot 1 it works but CPU 1 in slot 2 is mad...
running standalone is fine.

will try spare MB.

I think i have the power modules... the other card mouned on the CPU adapter card, both CPU cards were original CPU 1 (differente machines) no impact?
