Gateway 9415 Installing memory, ■DIMM banks must be populated in order, starting with Bank, DIMM banks must be populated using the following guidelines:

Installing memory

Your server supports from 256 MB to 16 GB of total memory. Supported DIMM sizes include 256 MB, 512 MB, 1 GB, 2 GB, and 4 GB.

Caution Modules must be installed in banks in identical pairs. Use only DDR2-400 compliant, 240-pin, SDRAM registered ECC, DIMM memory modules.

Memory modules must be installed in pairs to completely fill each bank and the banks must be filled in order. If memory is installed incorrectly, your server will not start.

Caution	When using Dual Rank (double row) DIMMs, a maximum of four loads
	per memory channel is supported. This means a maximum of four
	dual rank DIMMs can be populated on this system board.

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 1.■Dual rank (double row) DIMMs must be populated before single rank DIMMs.
