Installing Memory - Gateway E-9220T User Manual

Installing memory

When you upgrade your server memory, make sure that you install the correct type of
memory in your server. Your server supports from 256 MB to 8 GB total memory. Supported
DIMM sizes include 256 MB, 512 MB, 1 GB, and 2 GB.
Caution
The BIOS configures the memory controller to run in either single channel or dual channel
mode, depending on the following:
If one or more fully populated DIMM banks are detected, the memory controller
■
will run in dual channel mode.
If only a single DIMM is present, the memory controller will run in single channel
■
mode.
DIMM banks must be populated using the following guidelines:
DIMM banks must be populated in order, starting with Bank 0.
■
Dual rank DIMMs must be populated before single rank DIMMs.
■
When using Dual Rank (double row) DIMMs, a maximum of four loads per memory
■
channel is supported, and therefore a maximum of four dual rank DIMMs can be
populated on this system board.
Memory modules must be identical in each bank. Use only
DDR2-533 MHz, ECC unbuffered, 240-pin DIMM memory modules
in 256 MB, 512 MB, 1 GB, or 2 GB sizes.
Memory modules must be installed in pairs, to completely fill each
bank, and the banks must be filled in order. If you have memory
installed incorrectly, your server will not start up.
