T710 memory config

Question

Hi, Apologies about this as I know this has been discussed millions of times. I have a T710 with 12Gb of ram running in Optimixed mode. I purchased another 12Gb which matches the existing RAM from Crucial (single rank 2Gb PC3-1333) but I am struggling to get it to show up or the server to boot sometimes. The existing memory is in 1-4-7 on both banks of dimms (I have 2 CPUS) I tried 2-5-8 no show. I just upgrade the bios to 6.4.0 too Can someone offer advise on which config I should use with my RAM. Currently I am getting mem error on boot as slots 1-4-7 aren't available in advance eec mode. In addition to this the config in the openmanage software shows Memory Operating Mode Configuration Optimizer DIMM_A1 DDR3 - Synchronous Unregistered (Unbuffered) 2048 MB DIMM_A2 DDR3 - Synchronous Unregistered (Unbuffered) 2048 MB DIMM_A3 DDR3 - Synchronous Unregistered (Unbuffered) 2048 MB DIMM_A4 [Not Occupied] DIMM_A5 [Not Occupied] DIMM_A6 [Not Occupied] DIMM_A7 [Not Occupied] DIMM_A8 [Not Occupied] DIMM_A9 [Not Occupied] DIMM_B1 DDR3 - Synchronous Unregistered (Unbuffered) 2048 MB DIMM_B2 DDR3 - Synchronous Unregistered (Unbuffered) 2048 MB DIMM_B3 DDR3 - Synchronous Unregistered (Unbuffered) 2048 MB DIMM_B4 [Not Occupied] DIMM_B5 [Not Occupied] DIMM_B6 [Not Occupied] DIMM_B7 [Not Occupied] DIMM_B8 [Not Occupied] DIMM_B9 [Not Occupied] The RAM I purchased is Crucial CT2704708 6GB kit (2GBx3), 240-pin DIMM Upgrade for a Dell PowerEdge T710 System Have I made a booboo??

According to the specs you provided, the Crucial memory is registered:

Crucial 6GB Kit (3 X 2GB) PC3-10600 DDR3-1333MHz ECC Registered CL9 240-Pin DIMM 1.35V Low Voltage Single Rank Memory for Dell PowerEdge T710 Server Mfr P/N CT2704708

You will need UDIMM's to match what you already have.
