mixing memory in server x3650 M4 7915

2019-10-16, 15:06 PM

I have a problem and I am not sure if I can install the memory 16GB (1x16GB, 2Rx4, 1.35V) PC3L-10600 CL9 ECC DDR3 1333MHz LP RDIMM and memory 8GB (1x8GB, 2Rx4, 1.35V) PC3L-10600 CL9 ECC 1333MHz LP RDIMM, exactly I would like to know if is possible to mix memory  with different size. 

 

Currently my server has 16x 8GB memory, and I would like to add 8x more 16GB

Hello mixing memory size is not a problem.  In this case the important aspect to verify is that the memory used is the same specifications ie protection technologies, voltage and bus speed. 

 

The exception to this satement is that if memory mirroring is used, DIMMs must be installed in pairs (minimum of one pair per each CPU), and both DIMMs in a pair must be identical in type and size.

 

Could you supply the part number of the memory that you are using and also which you would like to use so we can make sure this is a tested option? 

 

Please make sure that the memory protection technologies you are going to use is the same as what was previously used.  As mixing different types of memory (UDIMMs, RDIMMs, HyperCloud DIMMs, and LRDIMMs) is not supported.
