Level 2 External Static RAM (SRAM) Cache
The motherboard you purchase may either have 0KB, 256KB, or 512KB.
Most likely you will have two cache chips onboard (see "Map of Mother-
board" for locations), then you have 256KB pipelined bust SRAM cache. A
cache module can be used to upgrade the 256KB version to 512KB and the
0KB version to 256KB or 512KB.
IMPORTANT: You must set jumper 16 "Total Level 2 Cache Size Set-
ting" on page 9 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.
Compatible Cache Modules for Motherboard PCB 1.01
NOTE: Motherboard PCB 1.0 can only use ASUS CM1 Rev. 1.6 to up-
grade the 256KB version to 512KB. 0KB version can use all modules for
upgrade to 256KB or 512KB except the ASUS CM1 Rev. 1.6.
