KRX3200AK2/1G

1GB (512MB 64M x 72-Bit x 2 pcs.)

Registered PC3200 ECC CL2.5 184-Pin DIMM Kit

DESCRIPTION:

Kingston's KRX3200AK2/1G is a kit of two 64M x 72-bit (512MB) DDR400 CL2.5 SDRAM
(Synchronous DRAM) registered ECC memory modules. Total kit capacity is 1GB. The components
on each module include eighteen 32M x 8-bit (8M x 8-bit x 4 Bank) DDR400 SDRAM in TSOP
packages. Each 184-pin DIMM uses gold contact fingers and requires +2.6V. The electrical and
mechanical specifications are as follows:
