Memory options

IMPORTANT:
mix these two types causes the server to halt during BIOS initialization.
The memory subsystem in this server blade can support RDIMMs or UDIMMs. Both types are referred to as
DIMMs when the information applies to both types. When specified as RDIMM or UDIMM, the
information applies to that type only. All memory installed in the server blade must be the same type.
The server blade supports the following DIMM speeds:
•
Single- and dual-rank PC3-10600 (DDR-1333) DIMMs operating at 1333 and 1066 MHz
•
Quad-rank PC3-8500 (DDR-1067) DIMMs operating at 1066 MHz
Depending on the processor model, the number of DIMMs installed, and whether UDIMMs or RDIMMs
are installed, the memory clock speed may be reduced to 1066 or 800 MHz. For more information on
the effect of DIMM slot population, see "General DIMM slot population guidelines (on page 33)."

Memory subsystem architecture

The memory subsystem in this server blade is divided into channels. Each processor supports three
channels, and each channel supports two DIMM slots, as shown in the following table.
