Memory
This motherboard includes two, 184-pin, dual in-line memory module (DIMM)
sockets. You can install corresponding PC 3200 (DDR400), PC 2700
(DDR333), or PC 2100 (DDR266) memory modules. You must install at least
one memory module to ensure normal operation. If you install two modules,
they must be the same speed. Mixed memory modules from different manufac-
turers is not recommended.
Installation of DDR Memory
1. There is only one gap in the center of the DIMM socket, and the memory
module can be fixed in one direction only. Unlock a DIMM socket by pressing
the module clips outward.
2. Align the memory module to the DIMM socket and insert the module verti-
cally into the DIMM socket.
3. The plastic clips at both sides of the DIMM socket will lock automatically.
