Static RAM (SRAM) for Level 2 (External) Cache
The motherboard you purchase may have either 0KB, 256KB, or 512KB onboard.
If you have both onboard cache chips (see "Map of Motherboard" for locations) and
a Cache Expansion Slot, then you have 256KB. If you only have onboard cache
chips, then you have 512KB. An "ASUS" or "COAST" cache module can be used
to upgrade the 256KB version to 512KB. The 512KB version cannot be upgraded
any further. If there is no onboard cache, you may install a SIMM cache module of
either 256KB or 512KB.
IMPORTANT: You must set "Total Level 2 Cache Size Setting" jumper on
page 8 when changes are made to your cache size.
Insert the module as shown. Because the number of pins are different on either side
of the break, the module will only fit in the orientation as shown.
