Memory Marked as Failed

Posted on 2007-10-16

I've got a server with a Intel SE7525RP Motherboard and 1x Corsair 1GB ECC DDR2 Memory chip on it.
The server has lately started to give an error when I reboot it.

Before it goes into Windows (while loading the BIOS) it stops and give me the following errors:

1.  Error (8502) Bad memory in DIMM 1A
2.  Error (8508) All memory marked as failed. Force all memory back online [PRESS F2)

I have replaced the memory chip and I still get the same error

Any ideas on what this can be?

    Maybe the slot went bad or you got bad replacement RAM. First reset your BIOS to defaults, maybe you changed some memory timing value to a wrong one. Then run memtest86+ on all modules separately, and also in different slots. You'll find memtest86+ on the UBCD.

    Dear all

    I found the problem... I replaced the ram chips. After that I still got the same error on when I boot saying that the memory in slot A0 is marked as failed.

    I went into the BIOS. There is a option rescan memory <DISABLED>. I enabled it and the problem was gone!!
