PowerEdge R510 Memory Upgrade

I have looked through a lot of similar posts but still am unsure of how I should approach this.

We have a PE R510 Single CPU with 3x8GB memory modules.  Current Memory Operating Mode is Optimizer.

Current Configuration (according to OMSA):

DIMM_A1: 8GB DDR3

DIMM_A2: 8GB DDR3

DIMM_A3: 8GB DDR3

DIMM_A4: Empty

DIMM_B1: Empty

DIMM_B2: Empty

DIMM_B3: Empty

DIMM_B4: Empty

I have 2x16GB modules on hand and am wondering if it is possible to add these 2 modules to this server to increase available memory.  Is it possible and if so what slots would I add them to?

Thanks

Kevin

Hello.

The R510 quite unique in its memory set up. It has 3 channels, CH0, CH1 &CH2 with 4 slots. See diagrammatic illustration below:

The memory must be the same on the same channels and the population of the DIMMs is in the order A1, A2, A3 &A4. Try populating the slots as follows;

A1 &A4 = 16 GB

A2 &A3 = 8GB

See pages 114 - 119 of the users' guide for more information: http://downloads.dell.com/manuals/all-products/esuprt_ser_stor_net/esuprt_poweredge/poweredge-r510_o...

Let me know how this works out.

Thanks Robert.  That makes sense.  It may be a few days before I try it but I will report back with how it went.

RE: PowerEdge R510 Memory Upgrade

Hi Robert,

It did not work, during boot there was a message along the lines of A1, A2, A3 must be the same.  Booted into windows fine though.  I tried a few different combinations but in the end I realized it was a Windows Server 2008 R2 Std server so it only supports 32GB of memory.  Just used the 2 16GB modules in A1 and A4 and that's working fine.

Thanks for your help.

Nice to know that you figured it out! See link for more information on Windows Server OS memory limitations: https://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).aspx
