6 sockets( 3 Bank of 2) The memory module sockets are arranged in three banks on two channels (A and B). The memory module banks are identified as follows:
l Bank 1: DIMM1_A and DIMM1_B
l Bank 2: DIMM2_A and DIMM2_B
l Bank 3: DIMM3_A and DIMM3_B

General Memory Module Installation Guidelines
-If only one memory module is installed, it must be installed in socket DIMM1_A or DIMM1B.
-If two or more memory modules are installed, they must be installed in pairs of matched memory size, speed, and technology.
-The system supports both single-ranked and dual-ranked memory modules.
-If you install both single-ranked and dual-ranked memory modules, the dual-ranked memory modules must be installed in bank 1.
-Dual-ranked memory modules are not supported in bank 3.

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 1850 has 6 ( 3 Bank of 2) 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.
