Hardware options installation 45
Memory options
The server memory subsystem supports only UDIMMs.
The server supports dual-rank, PC3-10600E (DDR3) DIMMs operating at a speed of 1333 MHz.
Depending on the processor model and the number of DIMMs installed, the memory clock speed might be
reduced to 1066 or 800 MHz. For more information, see "General DIMM slot population guidelines (on
page 47 )."
DIMM identification
To determine DIMM characteristics, use the label attached to the DIMM and the following illustration and
table.
