Chapter 1 Motherboard 7KM400MN
The motherboard supports a maximized 3GB memory. It pro-
vides three 184-pin unbuffered DDR sockets and each supports
64MBto1GBDDRmemorymodule.
1.6.DDR SDRAM Installation
The motherboard operates with Socket 462 for AMD AthlonTM
and DuronTM processor. The CPU should always have a Heat Sink
and cooling fan attached to prevent overheating.
CPU Installation Procedures for Socket 462
1. Pull the lever sideways away from the socket then raise the
lever to a 90-degree angle.
2. Locate Pin 1 in the socket and look for the white dot or cut edge
in the CPU. Match Pin 1 with the white dot/cut edge then
insert the CPU.
3. Press the lever down to complete the installation.
