Upgrading Cache Memory - TYAN TITAN I Manual

3.12 Upgrading Cache Memory

The S1461/3 main board comes standard with a 256KB 2nd level cache. It
uses 8pcs of 32K*8 SRAM's Y ou can upgrade the cache to 512KB with
64K * 8 SRAM to improve system performance.
NOTICE: The 64K*8 SRAM chip is longer in length than the 32K*8
chip. Do not insert the 32 K*8 SRAM chip into the top four pin
holes of the socket, it could cause serious damage to your SRAM
chips. Refer to the diagram below.
All SRAM chips must be 15ns (nanoseconds) or faster. The chart below
shows the chips you need for each configuration.
