NOTE
To remove an internal removable flash memory drive, push down on the locking collar to unlock the
drive before you remove the drive.
The server supports 1.5 V, 240-pin, 1 GB and 2 GB PC3-10600 or 4 GB, 8 GB, and 16
GB PC3-8500 double data-rate (DDR) III, registered synchronous dynamic
random-access memory (SDRAM) with error correcting code (ECC) DIMMs. These
DIMMs must be compatible with the latest PC3-10600 or PC3-8500 SDRAM Registered
DIMM specifications.
The server supports up to eight memory cards. Each memory card holds up to eight
DIMMs.
At least one memory card with one pair of DIMMs must be installed for the server to
operate.
When you install additional DIMMs on a memory card, be sure to install them in pairs.
The DIMMs in each pair must match each other.
You do not have to save new configuration information to the IMM when you install or
remove DIMMs. The only exception is if you replace a DIMM that was designated as
disabled in the Setup utility Memory Settings menu. In this case, you must re-enable the
row in the Setup utility or reload the default memory settings.
When you restart the server after you add or remove a DIMM, the server displays a
message that the memory configuration has changed.
Memory cards in connectors 1 and 2 support microprocessor 1, memory cards in
connectors 3 and 4 support microprocessor 2, memory cards in connectors 5 and 6
support microprocessor 3, and memory cards in connectors 7 and 8 support
microprocessor 4.
There are four memory power buses, which are split among the eight memory cards.
Populate the memory-card connectors to match the microprocessor installation, in the
following order: 1, 7, 3, 5, 2, 8, 4, 6. (Microprocessors must be installed in the following
order: 1, 4, 2, and 3. See "Installing a microprocessor" on page 67 for more information.)
