Hey there.
I have an older DL160 G6 server, which came configured with 2 x 4 GB ram.
I got 2 other identical memory sticks (Samsung 1x4R, 10600R ECC, 4 GB). So all 4 dimms are identical.
The first 2 were installed in the usual 3A slots for each CPU.
I have added the extra 2 in the 6B slots. The system boots, shows 16 GB of memory in BIOS, but when the SO finishes booting it restarts, a red led lights on the front, and bBIOS says Unrecoverable ECC error on slot 6B on CPU0.
At first i thought the 2 new DIMMS were deffective, but after moving them to 9C (leaving 6B empty), the system boots and wotks just fine, with all 16 GB available. So i have come to the conclusion the 6B slot on CPU0 is deffective.
Now for the question. Can i populate more slots on this server, skipping 6B? I do not have other DIMMS at my disposal at the moment, so i cannot test. But is it possible to have for example 6 x 4 GB dimms, placed in 3A,9C,2D slots for each CPU? leaving 6B empty.
