unknown beep code from s3420GPLX

Hi,

I just assembled a motherboard s3420GPLX with Intel XEON X3470 (2,93 GHz) and 2x 8GB RAM DDR3 - 1333 1.35v (Crucial CT8G3ERSLD41339.36FMD), placed in the blue slots. Video remains blank, and I hear 6 beeps after powering on.

After pressing the power switch again to power off the computer, there are some beeps again (high and short): 1 - 5 - 4 - 2

(The LED lights are changing during that. If it could help to tell, I need instruction how to read them.)

I could not find any information about these beep codes, and so I wonder what might be wrong and how to correct it. Can anybody help me with this?

TIA.

Re: unknown beep code from s3420GPLX

1-5-4-2 is a Power Fault. See the article http://www.intel.com/support/motherboards/server/s3420gp/sb/CS-031462.htm Intel� Server Board S3420GP — 1-5-4-2 Beep Sequence when changing Intel� VT Settings in the BIOS

If that doesn't help, check your power supply and chassis against the http://www.intel.com/support/motherboards/server/s3420gp/sb/CS-031016.htm Intel� Server Board S3420GP — Tested chassis list

Re: unknown beep code from s3420GPLX

Hi,

I tested it again, and the 1-5-4-2 beep sequence when switching off has gone -don't know why.

What still remains is the 6 beeps during power up and the black screen. Meanwhile I figured out that the LEDs are flashing in a repeating loop like this:

a) Power On

b) 0001 1101

c) 0111 1101

d) 1101 0111 & 6x beep

e) GOTO b)

What does that mean?

Re: unknown beep code from s3420GPLX

Since I now found the User's Guide, I guess I made a mistake when reading the diag LEDs. I watched them from the front side, but I since I read the User's Guide, am not sure if I had to read it from the rear side.

Viewed from the front:

LEDs Hex Desc.

""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

0001 1101 0x1D n/a

0111 1101 0x7D n/a

1101 0111 0xD7 Trying boot selection

viewed from rear:

LEDs Hex Desc.

""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

1011 1000 0xB8 resetting the removable media device

1011 1110 0xBE n/a

1110 1011 0xEB Memory Test Error: Memory failed Hardware BIST

If it is correct to read it from the rear side, it would make sense, because memory Built-In Self Test fails. does that mean that the memory modules are defective, or maybe that they don't match, e.g. regarding timing -or is it not possible to make a reliable statement? For choosing the memory modules, I trusted in the PC Configurator at my dealer's web site (alternate.de).

TIA.

I checked http://serverconfigurator.intel.com/sct_app.aspx# /SctTHOL/16723/Intel%C2%AE%20Server%20Board%20S3420GPLX%20%28S3420GPLX%29 Server Configurator Tool , and although there are some Crucial DIMMs on there, I don't see any PC3-10600.

Re: unknown beep code from s3420GPLX

Hi Dan,

thanks a lot. What I see there ist that all RDIMMs are 1.5v. The modules I got are labelled 1.35v. Maybe that makes the difference?

What could convince me was a table of the beep codes (and their descriptions, of course). I don't know what the six beeps during POST will tell me. Do you have an idea whre to find this info?

TIA.
