Memory Upgrade for HP AlphaServer GS1280
HP AlphaServer GS1280 memory upgrade specification, AlphaServer GS1280 maximum memory, memory speed, and memory upgrade options.
Upgrade memory on HP AlphaServer GS1280 upto a maximum of 8GB RDRAM memory per CPU supported
Keep these points in mind when installing a memory option or replacing a RIMM:
1. Each CPU can have one or two groups of four RIMM modules connected.
2. An optional fifth RIMM (RAID option) may be selected for redundancy. One RAID option must be selected for each four RIMM memory options on one CPU, but
RAID options do not have to be selected for all CPUs.
3. All the RIMM modules connected to one CPU must be the same size (e.g. 256 MB) and speed specification (e.g. 800 MHz)
4. Given CPUs are only compatible with the memory part numbers shown below:
1.3 GHz CPU, HP Memory Part: 3X-MS7AC-xx (1066MHz)
1.15 or 1.0 GHz CPU, HP Memory Part: 3X-MS7AB-xx (800 MHz)

HP AlphaServer GS1280 Memory Upgrade options.
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 AlphaServer GS1280 has 8 Sockets per CPU 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.
