DESCRIPTION
Kingston’s KHX1866C9D3T1K2/4GX is a kit of two 256M
x 64-bit (2GB) DDR3-1866 CL9 SDRAM (Synchronous
DRAM) memory modules, based on sixteen 128M x 8-bit
DDR3 FBGA components per module. Each module kit
supports Intel
x 64-bit (2GB) DDR3-1866 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
DDR3-1866 at a low latency timing of 9-11-9-27 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. The JEDEC
standard electrical and mechanical specifications are
as follows:
