Description
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.
