4GB (2GB 256M x 72-Bit x 2 pcs.)
DDR2-533 CL4 ECC 240-Pin DIMM Kit
DESCRIPTION:
ValueRAM's KVR533D2E4K2/4G is a kit of two 256M x 72-bit (2GB) DDR2-533 CL4
SDRAM (Synchronous DRAM) ECC memory modules. Total kit capacity is 4GB. The
components on each module include eighteen 128M x 8-bit (32M x 8-bit x 4 Bank) DDR2-533
SDRAM in FBGA packages. Each 240-pin DIMM uses gold contact fingers and requires
+1.8V. The electrical and mechanical specifications are as follows:
