DL 385 G7 memory configuration

[mihaib200]

Hi,

Someone can help me regarding the memory config for a DL 385 G7 with 2 processors?

I have a total of 32GB: 8 x 4GB (HP 4GB (1x4GB) Single Rank x4 PC3-12800 (DDR3-1600) Registered CAS-11 Memory Kit 676331-B21) and i want to upgrade to minim 192 GB.

Can I add to the existing configuration 12 x 16 GB (HP 16GB (1x16GB) Dual Rank x4 PC3-12800R (DDR3-1600) Registered CAS-11 Memory Kit 684066-B21) for a total of 224GB. It is compatible with the previous memory?

How should i balance the RAM between the 2 processors ( i have 4 channels per CPU)? If it's not possible how many 16GB do i need to obtain minimum 192 GB?

I tried with the HPE memory configurator, but the 1600MHz memory it's not listed at all, even though it is present on the memory compatibility matrix for 385 G7.

Thank you,

PS: Another question, can i mix LPDIMM (low power memory) with standard RDIMM?

Do you think this is a valid config? No LP DIMM, only Standard RDIMM @ 1600 MHz:

Channel 0: 2x(16GB DR, 16GB DR, 4GB SR)

Channel 1: 2x(16GB DR, 0GB, 4GB SR)

Channel 2: 2x(16GB DR, 16GB DR, 4GB SR)

Channel 3: 2x(16GB DR, 0GB, 4GB SR)

The online mem config is not up-to-date (is not aware of the new STD RDIMM @1600 MHZ) and is not working correctly for this server.

I did this and everything was fine.
