SDRAM Performance
The V437216C04VDTG-75 memory module is
organized 16,777,216 x 72 bits in a 168 pin dual in
line memory module (DIMM). The 16M x 72
registered DIMM uses 18 Mosel-Vitelic 16M x 4
ECC SDRAM. The x72 registered modules are ideal
for use in high performance computer systems
where increased memory density and fast access
times are required.
