DIMM installation rules:

For servers with eighteen (18) memory slots: There are three (3) channels per processor; six (6) channels per server There are three (3) DIMM slots for each memory channel; eighteen (18) total slots Memory channel 1 consists of the three (3) DIMMs that are closest to the processor Memory channel 3 consists of the three (3) DIMMs that are furthest from the processor DIMM slots that are white should be populated first Do not mix Unbuffered memory (UDIMMs) with Registered memory (RDIMMs) Do not install DIMMs if the corresponding processor is not installed If only one processor is installed in a 2CPU system, only half of the DIMM slots are available To maximize performance, balance the total memory capacity between all installed processors It is not required, but it is recommended to load the channels similarly if possible You can only have up to eight (8) ranks installed per channel You can only install two quad-rank DIMMs per channel You can only install two UDIMMs per channel; if available, the third slot in the channel must remain empty Populate DIMMs from heaviest load (quad-rank) to lightest load (single-rank) within a channel Heaviest load (DIMM with most ranks) within a channel goes furthest from the chipset For memory mirroring mode, channel 3 must be unpopulated. Channels 1 and 2 are populated identically For lock-step mode, channel 3 must be unpopulated. DIMMs in channels 1 and 2 will be installed in pairs. The paired slots will be 1,4; 2,5; 3;6 on a 3DPC system or 1,4; 2,5; on a 2DPC system No mixing DIMM voltage; all DIMMs must be the same voltage DIMM slot/capacity/populated speed table DIMM Type -> Registered Dimms (RDIMMs) Unbuffered with ECC DIMMs (UDIMMs) DIMM Rank -> Dual Rank (2R) Quad Rank (4R) Single Rank (1R) Dual Rank (2R) DIMM Capacity -> 2GB 4GB 8GB 2GB 4GB 8GB 1GB 2GB 1GB 2GB DIMM Native Speed (MHz) -> 1333 1333 1066 * 1066 * 1333 * * 1333 SLOTS THAT CAN BE POPULATED 18/12 slot servers 18 18 18 * 12 * 12 * * 12 * MAXIMUM CAPACITY (GB) 18/12 slot servers 36 72 144 * 48 * 12 * * 24 POPULATED DIMM SPEED (MHz) 1 DIMM Per Channel 1333 1333 1066 * 1066 * 1333 * * 1333 2 DIMM Per Channel 1066 1066 1066 * 800 * 1066 * * 1066 3 DIMM Per Channel 800 800 800 * * * * * * * * - not supported by HP at this time.

NOTES:

Mixing DIMM speeds is allowed, but the system processor speed rules always override the DIMM capabilities If you do mix DIMM speeds, the memory bus will default to the minimum clock rate of all DIMMs in the system - even if the slower DIMM is on the other processor If you install 1x 1066MHz DIMM in channel 1 and 1x 1333MHz DIMM in channel 2, you still run at 1066MHz If you install 1x 1066MHz DIMM in channel 1 and 5x 1333MHz DIMMs with 1 DIMM Per Channel (DPC) in each of the other channels, you run at 1066MHz If you install 3DPC in one channel (if applicable) and 1DPC in all other channels, you run at 800MHz 95 Watt CPU's are required for 1333MHz DIMM speeds. All other CPU's are capable of up to 1066MHz References to the above MHz speeds are for the various speeds of DDR3 DIMMs; 1333 refers to DDR3-1333, etc. DIMM slot and configuration diagrams
