**4GB (2GB 256M x 64-Bit x 2 pcs.) DDR3-1600 M Hz CL9 240-Pin DIMM Kit** Kingstons KHX1600C9D3X2K2/4GX is a kit of two 256M x 64-bit 2GB (2048MB) DDR3-1600 M Hz CL9 SDRAM (Synchronous DRAM) memory modules, based on sixteen 128M x 8-bit DDR3 FBGA components per module. Each module kit supports Intel XMP (Extreme Memory Profiles). Total kit capacity is 4GB. Each module kit has been tested to run at DDR3-1600 M Hz at a low latency timing of 9-9-9-27 at 1.65V. The SPDs are programmed to JEDEC standard latency DDR3-1333 M Hz timing of 9-9-9 at 1.5V. Each 240-pin DIMM uses gold contact fingers & requires +1.5V. ** Features**
