Memory Module Specifications
KVR400D2D4R3K2/8G
8GB (4GB 512M x 72-Bit x 2 pcs.) DDR2-400
CL3 Registered 240-Pin ECC DIMM Kit
DESCRIPTION
ValueRAM’s KVR400D2D4R3K2/8G is a kit of two 512M x
72-bit 4GB (4096MB) DDR2-400 CL3 SDRAM (Synchronous
DRAM) “dual rank” registered ECC memory modules.Total kit
capacity is 8GB (8192MB). The components on each module
include eighteen stacked 512M x 4-Bit (thirty-six 256M x 4-bit)
DDR2-400 SDRAM. Each 240-pin DIMM uses gold contact
fingers and requires +1.8V. The electrical and mechanical
specifications are as follows:
SPECIFICATIONS
Clock Cycle Time (tCK) CL=3 5ns (min.) / 8ns (max.)
Row Cycle Time (tRC) 55ns (min.)
Refresh to Active/Refresh Command Time (tRFC)
105ns
Row Active Time (tRAS) 40ns (min.) / 70,000ns (max.)
Single Power Supply of +1.8V (+/- .1V)
Power 5.310 W (operating per module)
UL Rating 94 V - 0
Note: The module defined in this data sheet is one of several configurations available under this part number. While all configurations are compatible, the DRAM
combination and/or the module height may vary from what is described here.
