NOTES: After June 1996, systems with 256-KB cache have cache installed directly on the system board and are not upgradable (no cache card connector or cache upgrade sockets). Systems with 512-KB cache use a 512-KB cache card.
The only 32-MB SDRAM DIMMs validated for use in this computer are the following:

Samsung KMM366S403AT1-G2
Hitachi HB526A464EN-10
Samsung KMM366S403AT-G2
Toshiba THMY644021AEG-12A
The system may not recognize other 32-MB SDRAM DIMMs and may fail POST.
When the system memory size is increased above 64 MB in a system with the Intel® Pentium® VX chip set, the system slows down. The problem is the cache limits of the chip set. The second-level (L2) cache can store (cache) memory only for accesses made in the lower 64 MB of main memory due to the size of the cache tag. If more than 64 MB is installed in the system, any memory access to data above the 64 MB is not cached. The system runs cacheless for memory accesses. The Microsoft® Windows® operating system uses pages of memory throughout the entire memory space so some accesses fall above the 64-MB region, which causes a decrease in performance. In effect, instead of getting a performance gain for adding more memory to a base 64-MB system, in many instances the performance is slower.
Additionally, many games that use MS-DOS® extenders are loaded at the top of the memory space so all accesses to the code are cacheless.
