Choose the following RAM Memory Upgrade for IBM eServer xSeries 445 8870. 

How much memory can I upgrade my IBM eServer xSeries 445 8870 to and what is memory type it takes?

You can upgrade your IBM eServer xSeries 445 8870 upto a maximum of 64.0 GB, with maximum of 4GB per slot in 16 (8 banks of 2) memory slots. The IBM eServer xSeries 445 8870 takes the PC2100 Registered ECC DDR SDRAM DIMMs. An optional xSeries 445 SMP Expansion Module can be installed to support additional processors and another 16 DIMM sockets for a total system memory capacity of 64 GB. Memory Type.

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 IBM eServer xSeries 445 8870 has 16 (8 banks 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.
