MB intel s5520sc + dual xeon W5580 boot problem

Hi guys.

I assembled the parts but the system doesn't boot, I can only see black screen - no way to go the BIOS- (PSU starts ON, Hard drive runs, standby led on MB is on, alert leds (cpu and ram) are OFF on the MB)

The 8 leds array on the back seem to report error 4 (it stops there), alias “Early processor initialization where system BSP is selected”

Configuration:
- MB: Intel s5520sc (on the front panel only power button is connected)
- CPU: XEON 2xW5580 (I ‘m trying with only 1 CPU)
- RAM: 1 Gb bank on slotA1 ( tried to change, I tried without)
- 24 pin power is linked
- 2 x 8 pin eps 12v power connector is linked
- only vga connected
-the only connector not linked is the “Auxiliary Power Supply Signal Connector (J9K2)”, alias 5 pins connector for PMBus (is it necessary to boot?).

do I have to buy the intel PSU with 5 pins Auxiliary Power Connector ?
do I have to buy the whole Intel chassis?
Do I have to throw all away?

Please help me I tried everything!


Thank you for any help, I’m new to server boards and dual CPU.

Did you contact Intel? They should be able to answer your questions.

hi lawrencelaw.
thank you for your post.

I will try changing RAM.
However I cannot get the BIOS... I think RAM test is done later in the POST. So I expect that RAM problem will be the following one, after I can get the BIOS screen !!!

Neither the keyboard seems to be working (caps lock doesn't change state).

Thank you also to ghislainG.
I did not asked to intel cause I got MB from german, cpu from US and after i got them it i learned the meaning of ES.
So I expect that they will say to buy intel chassis and return the CPU...

However I can see many people on the web using other chassis (mine in cosmos 1000s, like a few other...) and I don't want to think that chassis can make the difference. but may be I will buy, as I don't know how to resolve.

This night I will update BIOS, BMC, FRUs and so on....
I don't like the poorness of info about this MB....
Next time I will get a TYAN or asus, I expect very less problems.

I changed the ram, but problem is unchanged.
Now I will buy the intel chassis (I'm waiting for it).
I will tell you the results....

bye

hi bipi
I bought intel certified ram
I bought intel chassis
I changed MB
The problem is the same.
I must assume that both cpus are faulty.
an expert told me that are engineer sample; I didn't know. The one who sold them to me did not declare it (he is from kansas, I am from italy). I will never buy so expensive system; every problem is $multiplied by 10, and benefit are *1.2.

hi Jafang
I bought cpus on ebay from poisonr (topeka,kansas -avoid this seller, he is not honest- I must assume, and now he changed his nick, now he is "windowkeys" )
My pc is still not running. I have to test them with ASUS mb, I'm still waiting for it.
The system is now running with a xeon E5502, so system is ok. they are cpus that are not ok on this setup.
I hope asus mb will solve the problem, otherwise I want to see poisonr-windowkeys in jail.
I will swim across the ocean to give him kicks in his coconuts.

I will let you know.
If you have news please write...
