AMD Opteron processor with Direct Connect Architecture
DDR 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 400 MHz (PC3200) or 333 MHz (PC2700) DDR memory only. Main memory is
directly connected to the processor through the Direct Connect Architecture. There are 8 DIMM slots which provide 6.4 GB/s
bandwidth per processor. It can support a maximum of 8 GB of RAM with one processor installed, 32 GB of RAM when both
processors are present.
Memory must be added in pairs. Match DIMM pairs by size and type.
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).
MAXIMUM MEMORY
Supports up to 32GB of DDR SDRAM, in a configuration of 8 GB per processor (over 12 GB requires dual CPUs).
POSSIBLE MEMORY CONFIGURATIONS
Not all memory configurations possible are represented below.
