When upgrading memory DIMMs 1A and 3A must match. DIMMs 5B and 7B DIMMs 2C and 4C and DIMMs 6D and 8D must match and must be installed as a pair. When DIMMs 1A and 3A are populated the system is automatically configured for 2: 1 interleaving. When all 4 banks are populated the system is automatically configured for 4: 1 interleaving. When four six or eight DIMMs are populated with identical DIMMs the system is automatically configured for bank interleaving

NOTE: In the online spare configuration the ROM automatically configures the last populated bank as the spare memory. If only banks A and B are populated bank B is the spare bank. If banks A B and C are populated bank C is the spare bank Online spare memory is configured through RBSU.

NOTE: Mirrored Memory uses mirrored banks to provide a high level of memory redundancy. Customer chooses to implement or not: User selectable via BIOS and default is off.

1. A dual inline memory module (DIMM) consists of a number of memory components (usually black) that are attached to a printed circuit board (usually green). The gold pins on the bottom of the DIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a DIMM are not connected to each other.
2. Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered or Fully Buffered modules). Standard DDR3 240-pin DIMMs are currently available in DDR3 PC3-8500 SDRAM. Additional speeds will be added as the technology becomes available.
3. The number of black components on a 240-pin DIMM can vary, but it always has 120 pins on the front and 120 pins on the back, for a total of 240.240-pin DIMMs are approximately 5.25 inches long and 1.18 inches high, though the heights can vary. While 240-pin DDR3 DIMMS, 240-pin DDR2 DIMMs, 184-pin DDR DIMMs, and 168-pin DIMMs are approximately the same size, 240-pin DIMMs and 184-pin DIMMs have only one notch within the row of pins.

1. If you are not sure what to buy or need any help, please provide your Server/Workstation Make, Model and Processor Speed and we will give you feasible advice. And also it will help us to double check at shipping that the memory upgrade is compatible.
