Kingston's KHX1600C9D3K2/8GX is a kit of two 512M x 64-bit (4GB) DDR3-1600MHz CL9 SDRAM (Synchronous DRAM) 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 8GB. Each module pair has been tested to run at DDR3-1600MHz at a low latency timing of 9-9-9-27 at 1.5V. The SPDs are programmed to JEDEC standard latency DDR3-1333MHz timing of 9-9-9 at 1.5V.
