Installing The Memory - TYAN Tomcat i845GV S2198 User Manual

2.10 – 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 S2198.
Note: The Tomcat i845GV has two DIMM sockets, which supports a maximum of four banks of
DDR memory (only supports 64 Mb, 128 Mb, 256 Mb, and 512 Mb technologies for
x8 and x16 devices.)
