Memory
Has 3 banks of 2 SIMM sockets, which will accept 4-/8-/16-/32-/64-MB SIMMs up to a maximum of 320MB (Acer's memory chart only went as high as 2x32MB, 2x64MB, 2x64MB, so I don't know if the board will accept all banks filled with 64MB SIMMs). Each bank must contain two identical chips (ie 2x 4MB or 2x8MB) though memory can differ between banks.
Issue - After upgrading memory beyond 64MB the memory count only shows 32MB or 64MB. This is a known problem and can be cured by downloading the latest version of the BIOS from Acer's website.
Cache
You might notice that the board does not come with an external second-level cache. This is because the second-level cache is already integrated in the Pentium II CPU card. The CPU card may come with 256-KB or 512-KB second-level cache size. Cache is not upgradeable.
