I have a brand new server. The motherboard is Intel S2600CP4, two 8-core Intel E5-2600 processors. RAM is 8 DIMM slots of 8 GB each (KVR1600D3D4R11SK4/32GI, I installed them into the blue slots), Power supply is 1050W Corsair.

Most of the time the server won't start up - the fans are spinning, but I don't have video signal. And it keeps restarting on its own every 3 mins. But maybe after 30 mins it will eventually load and show something on the screen. I even was able to install ESXi 5.0 (vSphere) on it. It recognizes both CPUs and all of the 64GB of RAM. But even then it worked only for around 5 hours and than restarted on its own. Also, before it starts successfully, it makes beeps "3-2"

What's the problem? That's a very expensive peace of hardware and I can't afford purchasing a new motherboard/CPU.

By the way, on the front panel the "System Status" LED is constantly amber (not blinking), even when the server started successfully. And also in the BIOS I can see lots of "processor 01 unable to apply microcode update 8160" fatal errors.

Please help me with issue, I will really appreciate this!

Try updating the BIOS/Firmware. And/or call your vendor. Also, what exact CPU's are you using? –  MichelZ Jun 18 '12 at 15:20
I've chatted with Intel customer support and they said that my chasis is not Intel-certified and could cause a problem. But I don't think it could be the case, because it has 3 good fans and plenty of airflow. Also the RAM I have doesn't appear to be tested by Intel. –  Ilya Suzdalnitski Jun 18 '12 at 15:38
Are these memory modules supported in this configuration? –  Tom O'Connor Jun 18 '12 at 15:53
"Chassis certification" sounds like Snakeoil. –  Tom O'Connor Jun 18 '12 at 15:53
@Tom O'Connor: They're good Kingston Server ECC modules that are supported by my motherboard. However they're not "tested" by Intel. –  Ilya Suzdalnitski Jun 18 '12 at 16:01
