DESCRIPTION

Kingston’s KHX8500D2K4/4G is a kit of four 128M x 64-bit 1GB (1024MB) DDR2-1066 CL5 SDRAM (Synchronous DRAM) memory modules, based on sixteen 64M x 8-bit DDR2 FBGA components per module. Total kit capacity is 4GB (4096MB). Each module kit has been tested to run at DDR2-1066MHz at a latency timing of 5-5-5-15 at 2.2V. The SPD is programmed to JEDEC standard latency 800Mhz timing of 5-5-5-18 at 1.8V. Each 240-pin DIMM uses gold contact ngers and requires +1.8V. The electrical and mechanical specications are as follows:

Row Active Time (tRAS) 39ns (min.) / 70,000ns (max.)

Single Power Supply of +1.8V (+/- .1V)

Power 2.025 W (operating per module)

UL Rating 94 V - 0

Operating Temperature 0° C to 55° C

Storage Temperature -55° C to +125° C

FEATURES
