DESCRIPTION
HyperX HX318C10FWK2/8 is a kit of two 512M x 64-bit (4GB)
DDR3-1866 CL10 SDRAM (Synchronous DRAM) 1Rx8 memory
modules, based on eight 512M x 8-bit DDR3 FBGA components
per module. Total kit capacity is 8GB. Each module kit 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 stan-
dard electrical and mechanical specifications are as follows:
