How much memory can I upgrade my Dell Precision Workstation 690 (750W Chassis) to and what is memory type it takes?

You can upgrade your Dell Precision Workstation 690 (750W Chassis) upto a maximum of 32.0 GB (64.0 GB w/option memory riser cards), with maximum of per slot in 8 (2 banks of 4) memory slots. The Dell Precision Workstation 690 (750W Chassis) takes the PC2-4200/5300 Fully Buffered ECC DDR2 SDRAM FBDIMMs. Memory may also be installed in pairs for Dual Channel DDR2 memory performance (4 banks of 2). 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 Dell Precision Workstation 690 (750W Chassis) has 8 (2 banks of 4) 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.
