**2GB (1GB 128M x 64-Bit x 2 pcs.) PC2-5300 CL4 200-Pin SODIMM Kit** Kingstons KHX5300S2LLK2/2G is a kit of two 128M x 64-bit 1GB (1024MB) DDR2-667 CL4 SDRAM (Synchronous DRAM) memory modules, based on sixteen 64M x 8-bit DDR2 FBGA components (per module). Total kit capacity is 2GB (2048MB). Each pair has been tested to run at DDR2 667 M Hz at low latency timing of 4-4-4-12 at 1.8V. The SPDs are programmed to JEDEC latency timing of 4-4-4-12 at 1.8V. Each 200-pin SODIMM uses gold contact fingers & requires +1.8V.
