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 HP Pavilion 521n has 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.
