Description
The V437464C24V memory module is organized
67,108,864 x 72 bits in a 168 pin dual in line
memory module (DIMM). The 64M x 72 registered
DIMM uses 18 Mosel-Vitelic 64M x 4 ECC SDRAM.
The x72 registered modules are idealforuseinhigh
performance computer systems where increased
memory densityand fast access timesarerequired.
