Configure Cache Memory The Atlas PCI-II motherboard supports 256
KB, 512 KB or 1 MB of L2 cache memory. Cache
memory is either surface-mounted
SRAMs or a
standard cache memory module.

Important
The Atlas PCI-II works with either the SMT cache
memory or a cache module, but not both.
If the surface-mount cache memory is used, the cache
module socket must be empty.
If a cache module is used, make sure that Pins 2-3 of J30
are shorted.
The cache module used must conform to the Intel
COAST Version 1.0 specification. A 160-pin cache
module connector is mounted on the motherboard.
Cache Jumpers J16, J26, J28, and J30 are three-pin bergs that select
the external cache size and type.
SMT Cache The Atlas PCI-II motherboard is shipped with 256
KB of L2 secondary cache memory arranged as
surface-mounted 32 KB x 8 SOJ chips.
