PowerEdge M710HD blade Max supported memory size with single CPU
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.

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).

You have the maximum amount of RAM that a single CPU will handle in the M710HD. The addition of a second CPU will allow more RAM than 36GB.

Hi Dev Mgr,
Thanks for your message, My HW details are as below:
Bios: 1.0.3
System memory type: ECC DDR3
Memory operation mode: optimizer mode
I insert 16GB 4RX$ PC3L - 8500R -7-10-F0 in 8 slot it suppose to give me 128 GB but it just give me 32 GB and while power on after the DELL logo it gives me message Maximum rank count exceeded. So what will be the fix for this and Dell Japan tech support keep saying its only support 4X9=36GB, which I also think bit strange.

Hi Dev Mgr,
6 slot with 16 gb memory with one CPU works fine so please ignore my last message.

Dev Mgr,
One more question, why it only support 6 Dimms any special reason. It means with single processor and 16 GB memory we only can populate up to 96 GB of memory.

Since the Intel Xeon 5500 series, the memory controller is in the CPU. So the dimmslots next to each CPU socket are connected to the memory controller in that CPU. So if a socket doesn't have a CPU, the dimmslots next to it are not going to give you anything.
