2048 MB DDR Server Memory Module
General Description
The CM75SD2048RLP is a Synchronous Dynamic RAM Dual Inline Memory
Module (DIMM), designed for applications in which both performance
and density are critical. The low 1.2 inch maximum height of this module
makes it ideally suited for use in 1U rackmount servers and appliances.
This DIMM includes Error Checking and Correcting (ECC) for maximum
reliability, and has registered address and control signals to enable fully
configured systems.
These modules are constructed using thirty-six 128Mx4 SDRAMs in FBGA
packages. The module also includes an EEPROM to support Serial Pres-
ence Detect (SPD) requirements. Decoupling capacitors are mounted on
the printed circuit board for each SDRAM device.
The synchronous design of these Corsair SDRAM DIMMs allows precise
cycle control with the use of the system clock. I/O transactions are pos-
sible on every clock cycle. The high clock frequency and high density of
this device enable a high level of performance to be achieved in advanced
workstations and servers.
