Dell PowerEdge M620 memory upgrade specification, PowerEdge M620 maximum memory, memory speed, and memory upgrade options.

Upgrade memory on Dell PowerEdge M620 upto a maximum of 768GB in dual processor configuration
PC3-8500/10600/12800 DDR3 REG ECC/ECC memory .(ECC supports 10600-1333MHZ speed only ), with maximum per slot in 12 Sockets/Processor (Total 24 Sockets with 2 Processor) memory slots. The Dell PowerEdge M620 takes the PC3-8500/10600/12800 DDR3 REG ECC/ECC memory .(ECC supports 10600-1333MHZ speed only ) Memory Type.

Dell PowerEdge M620 Memory Upgrade Specification
Standard Memory Maximum Memory Memory Expansion CPU Type Model/Chipset
8GB(Removable) 768GB in dual processor configuration
PC3-8500/10600/12800 DDR3 REG ECC/ECC memory .(ECC supports 10600-1333MHZ speed only )
12 Sockets/Processor (Total 24 Sockets with 2 Processor) Intel Xeon processor
System supports Max of 4GB ECC memory /slot
The system supports up to 12 DIMMs per processor (up to 24 DIMMs in a dual-processor configuration). The M620 has four memory channels per processor, with each channel supporting up to three DIMMs.
The M620 supports a flexible memory configuration, according to these basic rules:
Speed: If DIMMs of different speeds are mixed, all channels across all processors operate at the slowest DIMMís common frequency.
DIMM type: Only one type of DIMM is allowed per system: UDIMM, RDIMM, or LRDIMM. These types cannot be mixed.

What are memory sockets or slots and how are these divided into bank?

 

Memory Sockets or Slots are the place where memory RAM modules are inserted in the motherboard. The Dell PowerEdge M620 has 12 Sockets/Processor (Total 24 Sockets with 2 Processor) memory expansion slots. A memory bank is a group of memory expansion sockets, a bank must be completely filled with memory modules of the same size and type in order for the system to recognize and address the memory. i.e. :

2 sockets (2 banks of 1) This indicates that there are 2 memory slots. These are divided into 2 banks, and each bank consists of one memory slot. So you can add memory one piece at a time for the system to use.

3 sockets (3 banks of 1) This indicates that there are 3 memory slots. These are divided into 3 banks, and each bank consists of one memory slot. So you can add memory one piece at a time for the system to use.

4 sockets (2 banks of 2) This indicates that there are 4 memory slots. These are divided into 2 banks, and each bank consists of two memory slots. So you must add memory two pieces at a time (they must be the same size and type of memory) in order for the system to benefit from the upgrade.

8 sockets (4 banks of 2) This indicates that there are 8 memory slots. These are divided into 4 banks, and each bank consists of two memory slots. So you must add memory two pieces at a time (they must be the same size and type of memory) in order for the system to benefit from the upgrade.

12 sockets (3 banks of 4) This indicates that there are 12 memory slots. These are divided into 3 banks, and each bank consists of four memory slots. So you must add memory four pieces at a time (and they must be the same size and type of memory) in order for the system to benefit from the upgrade.
