DFI LP JR X58 32nm Xeon support

[rinma]

Hello, was just wondering if any of you guys are running X56xx Xeon on DFI X58 motherboards?
I have DFI LanParty JR X58 T3H6, and just got Xeon X5650. But the thing is it won't even POST. Actually it acts like there's no CPU installed - shows same error that I haven't seen before (L-state). Just to be sure i tried to start it without CPU and debug code was the same.

I updated CPU microcode manually (added 206C2 string) and flashed the motherboard but still same thing. Even left it unplugged and without the battery overnight to clear CMOS but nothing.

Motherboard is working, Core i7 920 works perfectly fine.

Any ideas?

I've seen this but can't find any additonal info about it.
