Kingston's KHX1600C9D3K3/12GX is a kit of three 512M x 64-bit (4GB) DDR3-1600 CL9 SDRAM 2Rx8 memory modules, based on sixteen 256M x 8-bit DDR3 FBGA components per module. Each module kit supports Intel XMP (Extreme Memory Profiles). Total kit capacity is 12GB. Each module kit has been tested to run at DDR3-1600 at a low latency timing of 9-9-9-27 at 1.65V. The SPDs are programmed to JEDEC standard latency DDR3-1333 timing of 9-9-9 at 1.5V. Each 240-pin DIMM uses gold contact fingers and requires +1.5V.
