DESCRIPTION:
Kingston's KHX5400D2K2/512 is a kit of two 32M x 64-bit (256MB) DDR2-675 CL4 SDRAM
(Synchronous DRAM) memory modules, based on four 32M x 16-bit DDR2 FBGA components (per
module). Total kit capacity is 512MB. Each pair has been tested to run at DDR2 675MHz at low
latency timing of 4-4-4-10 at 1.85V. The SPDs are programmed to JEDEC standard latency timing
of 4-4-4-12 at 1.8V. Each 240-pin DIMM uses gold contact fingers and requires +1.8V. The
electrical and mechanical specifications are as follows:
