Ml 350 G5 Memory slot problem

[Lmbyte]

Hi,

From yesterday, "Server fails to boot, all DIMM LEDs illuminate amber".

I have test the solution from the forum but not work.

If I put the pair of memory in slot 4D and 8D, always work and boot (This two pair of slot is never populate)

If I put the two pair of memory in 3E,4D,7E and 8D with 512 Kb DDR2 PC2-5300 EEC, always work

If I put the two pair of memory in 3E,4D,7E and 8D with 512 Kb DDR2 PC2-5300 EEC and a 1GB DDR2 PC2-5300 EEC, have work one time without any error in ILO, but in the second time of boot all DIMM LEDs illuminate amber.

If I put the memory that work in 1A,2B,5A and 6B all DIMM LEDs illuminate amber.

I'm sorry for my English, but I cannot diagnose the problem

Thanks
