Hmm, yeah I should probably try that (I was avoiding it).
Will let you know results.
It's currently running on the new CPU now - purring along.
Ideas?
Q1: Does this mobo require an Intel branded PSU (Like what's provided in an Intel Chassis) to properly operate in Dual CPU mode? I.E - Does the mobo require the AUX PSU 5-pin header to be actively connected to a PSU?
Q2: If yes, will any of these fit to the ATX PSU standard screw configuration? And do they have the 5-pin AUX output?

No the 5-pin AUX cable is not required to power up the server.
You may want to check if any standoffs underneath the board are in wrong positions. Also check CPU socket 2 carefully for bent pins, as they're quite fragile.
AHA!
I had a P4 connector *NOT* a P8 connector in the second CPU +12v header - probably should have clarified that to begin with eh?
The mobo obviously treats the P8 as 2 x seperate P4's and errored because half the P8 had no voltage across it.
Thanks for your assistance Edward - nice to know Intel still helps people with gear that's 2 generations old, much appreaciated.
