System Memory
Four 240-pin DIMM sockets are provided that support DDR2 400/533 MHz, non-ECC, unbuffered memory
modules in 256MB, 512MB, 1GB, and 2GB sizes, which may be installed as single DIMMs if desired. The
two memory channels are interleaved: Addresses are ping-ponged between the channels after each cache
line (64-B boundary). For dual interleaved mode, DIMMs must be installed in matched pairs, installed in
sockets with identical color (e.g. locations DIMM1 and DIMM3, then DIMM2 and DIMM4). If a total of 4GB of
DIMMs is installed, the maximum available memory will be approximately 3.24GB, with the balance of the
address space being consumed by other resources in the system. A complete list of tested memory is
available from the RadiSys web page
Memory Installation:
This motherboard includes four 240-pin slots with 1.8V for DDR2. You must install at least one memory bank to ensure
normal operation.
Installation of DDR2 Memory
1. There is only one gap in the middle of the DIMM slot, and the memory module can be fixed in
one direction only. Unlock a DIMM slot by pressing the module clips outward.
2. Align the memory module to the DIMM slot, and insert the module vertically into the DIMM slot.
DDR2 Memory bank
128 Pins
112 Pins
3. The plastic clips at both sides of the DIMM slot will lock automatically.
CAUTION
Be sure to unplug the AC power supply before adding or removing expansion cards or other
system peripherals, especially the memory devices, otherwise the motherboard or the system
memory might be seriously damaged.
