The M710HD's manual lists some examples of memory configurations, but that is by no means the list with the only supported options. So just because 36GB is the highest shown example with a single CPU, that doesn't mean it's the highest actual supported option.  If 2 processors support 12 x 16GB RDIMMs, then 1 processor will support 6 x 16GB RDIMMs. Just keep in mind the other memory rules (e.g. cannot mix UDIMM and RDIMM).
Hi, I am planning to upgrade two of PowerEdge M710HD blade to maximum possible memory size, but both servers have single CPU. Because of some application and OS license limitation I cant deploy second CPU, I follow up with dell Japan support and they came with, max size 4X9=36GB, which I already have. I just would like to double check that in case of single CPU max memory size go up to 36 GB or we have any other options? I purchase 16 GB X 16 dimms from dell and we provide service tag before we place purchase order.  Binaya
