Memory Module Specification
DESCRIPTION:
ValueRAM's KVR533D2Q8R4K2/4G is a kit of two 256M x 72-bit 2GB (2048MB) DDR2-533
CL4 SDRAM (Synchronous DRAM) "quad rank" registered ECC memory modules. Total kit
capacity is 4GB (4096MB).The components on each module include thirty-six 64M x 8-bit
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:
