Kingston's KHX18C11P1K2/16 is a kit of two 1G x 64-bit (8GB) DDR3-1866 CL11 SDRAM (Synchronous DRAM) 2 Rx 8 memory modules, based on sixteen 512M x 8-bit DDR3 FBGA components per module. Total kit capacity is 16GB. Each module kit has been tested to run at JEDEC DDR3-1866 at a low latency timing of 11-11-11 at 1.5V. Additional timing parameters are shown in the Pn P Timing Parameters section. Each 240-pin DIMM uses gold contact fingers & requires +1.5V.
