Brand New EVGA SR-2: ?Wierd? POST errors

Purchased two X5650's for supermicro dual xeon mobo
but then discovered EVGA SR-2 and then the ES L5640 hoot.

Now have two ES L5640's but need to burn new Bios.
The X5650's will be sold, but only after I burn the Bios for ES L5640's

Only using a single X5650 to burn the Bios so the other X5650 can be sold as new in the box.

System is currently bare bones:
(1) X5650 in CPU 0 socket with CPU 1 jumper in off position,
(2) GTX 275 video card,
(3) Single 1TB SATA
(4) Six working DIMMS from X58 Mobo (until new RAM arrives):
Kingston 2GB DDR3 1333MHz
The 12GB are in all the red DIMM slots, 1, 3, and 5
(5) Enermax Revolution85+ 920W Power supply with
8-pin EPS12V for CPU 1 and 4+4 pin EPS12V for CPU 0
as well as 6-pin PCI-E plugged in for both CPUs'

Config 1:
-------------
GTX 275 in Slot 5
POST error code 2E: Initialize output devices

Config 2:
-----------
Move GTX 275 to Slot 1
POST Error code C7: Early CPU initialization exit

WTF? Single CPU is OK? Right?
An ideas? I am stuck right now? What next?
 
Many more tests have occurred since original post.

Bios was reset multiple times by removing the CMOS battery, but same C7 POST error
Also ran each CPU alone, with appropriate disable jumper, but same C7 POST error

Paranoia checking for bent LGA1366 pins

Performed SAME TESTS placing both X5650 CPU's in Supermicro X8DTN+ dual xeon motherboard.
We are using the on board video with this MoBo.
But we get SAME beep code with Supermicro as with the EVGA SR-2.
Also noticed North and South bridge heat sinks were incredibly hot.

Conclusions:
1) The X5650 CPU's have been damaged, or
2) The memory is incompatible with the CPU's

Right?

Finally, a friend brought his memory over to perform some tests.
Demonstrate problem in Supermicro mobo
Pulled out EVGA SR-2 again, plugged in a CPU and heat sink and wired it up again.

BUT IT BOOTS JUST FINE!!!!!!!!!!!!!!!!!!!!!!!!!!

CTRL+ALT+DEL to reboot and get into BIOS, but no action.
OMG we forgot to connect the keyboard.
Connect KB and reboot
POST Error code C7: Early CPU initialization exit

Remove KB: Boots fine
Connect KB: C7: Early CPU initialization exit
......
Remove KB: Boots fine
Connect KB: C7: Early CPU initialization exit

The PS/2 plug got bent while rolling case over.
Just using this old PS/2 KB for the tests
I assume there was a short circuit in PS/2 plug
The KB is now in the trash.

BTW: The L5640's are now in and running great.
Might hang on to X5650's for a while though

How amazing that a fault keyboard could cause a POST error pointing to a faulty CPU
Always hated these cryptic POST messages
Four days of wasted time and effort
 
good to see you got it all working now.. time to join the [H] F@H team and put those puppies to the real test :D
 
Thanks for that
[H] F@H team? ... more info?

The puppies will get some severe testing cranking 24/7 on CFD (Computational Fluid Dynamics)
Multiple cores are great for this.
Top guys are running 32,000 cores on HPC clusters for months at a time.
Anyhow, air cooling is comfortable, 17 x 190 = 3.2 GHz for now.

Also, they have told me how much they are looking forward to meeting up with new 48GB friends next week.

Any idea what to do with Supermicro?
Nice MoBo, but no-one wants it.
Any way to increase the BCLK?

well with the SR-2 out all the other boards have gone out the door for consumers.. theres still server oriented people buying them though.. but no theres no way to increase the bclk on any of the other boards.. SR-2's the only overclockable server grade 2P board.. if anything id just throw the supermicro board on fleabay and see what you can get for it..

as far as F@H goes come by the distributed computing forum section.. most people are running the bigadv WU's on those things and theres tons of SR-2 help down there if you ever need it.. i think theres now about 10 people on the F@H team running SR-2 boards and a few people running the same exact processors you are running.. should give you some idea's on overclocking those processors..
