Description
The V437432E24V memory module is organized
33,554,432 x 72 bits in a 168 pin dual in line
memory module (DIMM). The 32M x 72 registered
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.

Serial Presence Detect Information
A serial presence detect storage device –
E2PROM – is assembled onto the module. Informa-
tion about the module configuration, speed, etc. is
SPD-Table for modules:
written into the E2PROM device during module pro-
duction using a serial presence detect protocol (I2C
synchronous 2-wire bus)
