Memory module
You must install at least one module in any of the two slots. Each module can be installed
with 256MB to 1GB of memory. Based on Dual DDR structure, when only one DDR
SDRAM DIMM is available, please insert it to DIMM1 slot, rather than DIMM2 slot, in
case that the system may not boot.
Do not remove any memory module from its antistatic packaging until you
are ready to install it on the motherboard. Handle the modules only by
their edges. Do not touch the components or metal parts. Always wear a
grounding strap when you handle the modules.
