The L2 cache is a tall card which is above the CPU socket and to the left of the B1 RAM socket. PTP 225s come with 1 MB cache (eight large square "data" chips and two small rectangular "tag" chips). The logically identical 9500 mobo (same ROM, anyway) comes with 512 KB of nonremovable cache (four "data" chips and two "tag" chips). The XLR8 upgrade is designed to be compatible with both soldered and carded cache. You can manually turn the mobo cache off, using the XLR8 control panel. Should your L2 cache be larger than your backside cache, then it is often better to leave it in, thereby giving you 64 KB L1 cache, 512 KB L2 cache and 1 MB L3 cache (the original L2 cache becomes L3 cache in this case). -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
