DESCRIPTION
HyperX HX318C10FB/8 is a 1G x 64-bit (8GB) DDR3-1866
CL10 SDRAM (Synchronous DRAM) 2Rx8 memory module,
based on sixteen 512M x 8-bit DDR3 FBGA components. This
module has been tested to run at DDR3-1866 at a low latency
timing of 10-11-10 at 1.5V. Additional timing parameters are
shown in the PnP Timing Parameters section below. The
JEDEC standard electrical and mechanical specifications are
as follows:
