2.14 – Installing the Memory

Before attempting to install any memory, make sure that the memory you have is compatible with the motherboard as well as the processor. For example, while PC1600 DDR modules are compatible with all DDR based motherboards, they will not work if you are required to run the motherboard and processor buses at 133MHz. For this, PC2100 DDR modules are required. Critically important is whether you’re using the recommended memory for the current board you have. For this information, please check TYAN’s web site at: www.TYAN.com.

The following diagram shows the types of RAM modules you may encounter.

Use only 184-pin unbuffered non-ECC memory for S2498.

Note: The Tomcat K7M has two DIMM sockets, which supports a maximum of four banks of DDR memory (only supports 64 MB, 128 MB, 256 MB, 512MB and 1GB technologies for x8 and x16 devices.)

2.15 – Memory Installation Procedure

When you install the memory modules, make sure the module aligns properly with the memory slot. The modules are keyed to ensure that it is inserted only one way. The method of installing memory modules are detailed by the following diagrams.
