Supports up to 64 GB of DDR2 SDRAM, in a configuration of 32 GB per processor (over 32 GB requires
dual CPUs and Quad Ranked DIMMS when supported).
NVIDIA Nforce Professional 3000 Series
DDR2 SDRAM ECC REGISTERED MEMORY
This chart does not represent all possible memory configurations. Each AMD Opteron processor has an
integrated memory controller that supports ECC Registered 667 MHz (PC2 5300P) DDR2 or ECC
Registered 533 MHz (PC2 4200) DDR2 memory. Main memory is directly connected to the processor
through the Direct Connect Architecture. There are 8 DIMM slots in total, with 4 DIMM slots per processor,
each processor offering a memory bandwidth transfer rate up to 10.2 GB/s. Over 32 GB requires dual
CPUs, and will require 8 GB DIMMS (when available)
Memory must be added in pairs. Match DIMM pairs by size and type. Use only HP tested and validated
memory
In a single processor configuration, install the first DIMM pair in socket set 1 (blue sockets), and the 2nd
DIMM pair in socket set 3 (black socket).
In a dual processor configuration, install the first DIMM pair in socket set 1 (blue sockets), the 2nd DIMM
pair in socket set 2 (blue sockets) and, if required, the 3rd pair in socket set 3 (black sockets) and the 4th
pair in socket set 4 (black sockets).
The memory sockets are laid out on the mainboard as below:
