1MB 15ns cache SRAM kit for 486 and Pentium machines. Tested working. Beware of fake SRAM. I also have single SRAM ICs for sale, and can make up different kits. This listing is for: 8 x 128K*8 ICs (32-pin) 1 x 64K*8 IC (32-pin) Your motherboard may need another 64K*8, or a different IC configuration altogether. Ask if you need different ICs and I can make up a custom kit for you (512K, 256K, etc). Check your motherboard manual or TotalHardware99 for the required cache ICs and jumper settings. Picture is just for reference. Actual chips may be different, compatible models.
