DESCRIPTION

HyperX HX421C14FWK4/64 is a kit of four 2G x 64-bit (16GB)
DDR4-2133 CL14 SDRAM (Synchronous DRAM) 2Rx8, memory
module, based on sixteen 1G x 8-bit FBGA components per module.
Each module kit supports Intel® Extreme Memory Profiles
(Intel® XMP) 2.0.
been tested to run at DDR4-2133 at a low latency timing of 14-14-14
at 1.2V.
Plug-N-Play (PnP) Timing Parameters section below. The
JEDEC standard electrical and mechanical specifications are
as follows:

Note: The PnP feature offers a range of speed and timing options to support
the widest variety of processors and chipsets. Your maximum speed will
be determined by your BIOS.
