The V437432S24V memory module is organized 33,554,432 x 72 bits in a 168 pin dual in line memory module (DIMM). The 32M x 72 unbuffered DIMM uses 9 Mosel-Vitelic 32M x 8 ECC SDRAM. The x72 modules are ideal for use in high performance computer systems where increased memory density and fast access times are required.
