The
1.9.2 Dual channel configuration
The four DIMM sockets are arranged in two channels: DIMM1 & DIMM2 in channel A; DIMM3 & DIMM4 in channel B. To enable dual channel operation, please install a matched pair of DIMMs in DIMM1 & DIMM3 (green sockets). If additional memory is to be used, another matched pair of DIMMs have to be installed in DIMM2 & DIMM4 (pur- ple sockets).
"Matched pair of DIMMs" means: same in speed (DDR266, DDR333, DDR400), same in size (128MB, 256MB, 512MB or 1GB), same in chip density (128 Mb, 256Mb or 512Mb and same in CSA latency. Any other memory configuration will result in single channel memory operation.
1.10 Memory Installation Procedures
To install DIMMs, first make sure the two handles of the DIMM socket are in the "open" position. i.e. The handles lean outward. Slowly slide the DIMM module along the plastic guides on both ends of the socket. Then press the DIMM module right down into the socket, until you hear a click. This is when the two handles have automatically locked the mem- ory module into the correct position of the DIMM socket. To remove the memory module, just push both handles outward, and the memory mod- ule will be ejected by the mechanism in the socket.
