First Boot: No Beep Code or Display

Hello. Been using these forums for reference for a while and have finally come across my first issue that I have been unable to find an answer for.


Experience: I am fairly green when building computers but have some experience and have been reading a lot.


My build (fairly high-end):

Motherboard (server board): Intel S2600CP4
CPUs: Intel Xeon E5-2680 (two)
Cooling: Corsair H80i (two)
RAM: Kingston 16GB KVR16R11D4/16I (two sticks)
SSD: Samsung 840 EVO 500GB 2.5”
PSU: Corsair RM1000 POWER SUPPLY,80
Case: Cooler Master Cosmos II


Issue: I am attempting my first boot but receive no display or beep codes (no beeps at all - even with no memory inserted). Case and CPU fans turn on, system-status LED is green indicating OK, no POST LEDs appear to be on, 5V LED is on, cooling unit appears functional.


Trouble-shooting so far:

I have gone through the list indicated here: http://www.tomshardware.com/forum/261145-31-perform-ste...

Except for unseating the CPU and re-checking the pins (I will do this tomorrow).

(Other) things I have tried and recorded:

Verified monitor works on other PC
Tried: 1 stick of RAM on each CPU, 2 sticks on master CPU, 1 stick on master, no sticks inserted
Removed SSD and DVD drive
Reset CMOS
Verified power connections to motherboard are solid
Performed paper-clip test on PSU using a digital multimeter
Finally have reduced system to a "breadboard" setup having my motherboard, 2 CPUs with cooling units, and PSU connected on an anti-static surface outside my case

Nothing I have tried has changed the fact that I cannot get beep codes or a display to appear.


I would greatly appreciate any advice to further check. I spoke briefly with Intel tech support and upon hearing that no beep code was issued with the RAM missing they proposed the motherboard may be faulty. However I would like to verify this as best as I can before waiting 2 weeks for a new one.

Thank you!

If no RAM is on board and your not even getting a error code, most likely the Mobo or one/both Xeons (you have two) is shot or misconfigured. I would just try with one Xeon first but I would say RAM time

Thanks for your response. I tried booting with just one CPU today without any change, and then swapped it with my other CPU and same thing. I doubt both CPUs would be shot so I'm thinking it must be the mobo. I'm going to contact Intel.

Thanks again.

Turns out the server board shipped with a BIOS version too old to support my v2 processors. It requires a BIOS update.
