Memory options This server contains eight memory cartridge connectors in each processor memory drawer. Each memory cartridge can contain eight DIMMs, for a total of 128 DIMMs, for a maximum memory configuration of 2 TB. The server supports the following DIMM speeds: • Single- and dual-rank PC3-10600 (DDR-1333) DIMMs operating at 1066 MHz • Quad-rank PC3-8500 (DDR-1066) DIMMs operating at 1066 MHz Depending on the processor model, the memory clock speed may be reduced to 1066 or 800 MHz.

Memory options
This server contains eight memory cartridge connectors in each processor memory drawer. Each memory
cartridge can contain eight DIMMs, for a total of 128 DIMMs, for a maximum memory configuration of 2
TB.
The server supports the following DIMM speeds:
•
Single- and dual-rank PC3-10600 (DDR-1333) DIMMs operating at 1066 MHz
•
Quad-rank PC3-8500 (DDR-1066) DIMMs operating at 1066 MHz
Depending on the processor model, the memory clock speed may be reduced to 1066 or 800 MHz.
DIMM support
The server supports the following DIMMs:
•
Single- and dual-rank PC3-10600 (DDR3-1333) DIMMs operating at 1066 MT/s
While single-rank DIMMs are supported, HP recommends dual-rank and quad-rank DIMMs since
they provide significant memory throughput and better memory protection (Online Spare memory
mode) over single-rank DIMMs.
•
Quad-rank PC3-8500 (DDR3-1066) DIMMs operating at 1066 MT/s
Single-, dual-, and quad-rank DIMMs
To understand and configure memory protection modes properly, an understanding of single-, dual-, and
quad-rank DIMMs is helpful. Some DIMM configuration requirements are based on these classifications.
A single-rank DIMM has one set of memory chips that is accessed while writing to or reading from the
memory. A dual-rank DIMM is similar to having two single-rank DIMMs on the same module, with only
