Hope this is in the correct area.

Let me begin:

I have

EVGA SR-2
2x Xeon E5620 (overclocked to 3.5 GHz 24/7)
Corsair AX1200 PSU
2x GTX 670 4GB
2x Cooler Master 212 EVO CPU coolers
24GB Corsair XMS3 9-9-9-27 1333MHZ RAM

Built in december 2012, almost a year old now. Running stable and perfect all this time. Browsing ebay a few weeks ago, I find Xeon X5650s for incredibly cheap, they are formerly $1000ish 6 core 3.06 GHz turbo processors. Naturally I jump on the deal and figure it'll be a nice little upgrade for my PC and I's anniversary =P

Plopped them both in the SR-2, go to boot... bam, nothing, no beeps, just an FF code on the POST LED display.

They're not ES chips, both are SLVB3 SSpec.
Cleared CMOS before putting the chips in...

Tested each CPU in the primary CPU slot without a companion in the secondary CPU slot, both of them booted (at least past FF, I didn't go any further because I didn't have heatsinks on for this diagnostic, too unweildy and time consuming to take them on/off for every test)

I put my E5620s back in that I've been running a year stable... and they both together in SMP boot just fine, I'm talking to you on the system right now...

Do you guys have any clue what my issue might be? I really want these damn Xeons to work together, they're like feuding siblings or something ATM. -_-

Yes, clearing the BIOS would wipe everything.
But I've never had the opportunity to play with dual xeons before, so I'm back to calling the customer support line to see if they have any suggestions.
Sorry I can't be of more help.

Wild guesses, but..
What about a BIOS update?
Any notes about the X5650 in the motherboard's manual or website documentation?
Are you overclocking the X5650's too? Or starting with default profiles.
I'd be tempted to call the support number for the motherboard and ask them if they know anything.

I have the newest BIOS available from EVGA... I started everything from blank, I didn't even get to the BIOS to overclock the X5650s, I would've eventually, I didn't make any profiles for my current E5620s at least, and I cleared the CMOS before installing the new X5650s, wouldn't this also remove the profiles?

I dont remember ever saving any overclocking profiles, but perhaps the motherboard is trying to load the E5620's overclocked profile on the X5650s...
