Installing the Memory

The IB865 CPU card supports two DDR memory sockets for a maximum
total memory of 2GB in DDR memory type. You can install unbuffered
& non-ECC DDR DIMMs. It supports DDR266/333 when installed with
CPUs that have clock speeds of 533MHz. It supports DDR266/320/400
when installed with CPUs that have clock speeds of 800MHz. The board
provides dual channel functionality for its DIMM slots. DIMM1 is for
one channel and DIMM2 is for the other channel. Enabling dual
channels can increase data access rates.
Basically, the system memory interface has the following features:
Supports two 64-bit wide DDR data channels
Available bandwidth up to 3.2GB/s (DDR400) for single-channel
mode and 6.4GB/s (DDR400) in dual-channel mode.
