SPECIFICATIONS

DESCRIPTION

FURY KF426S16IBK2/64 is a kit of two 4G x 64-bit (32GB)

DDR4-2666 CL16 SDRAM (Synchronous DRAM) 2Rx8, memory

module, based on sixteen 2G x 8-bit FBGA components per module.

Each module kit supports Intel® Extreme Memory Profiles

(Intel® XMP) 2.0. Total kit capacity is 64GB. Each module has

been tested to run at DDR4-2666 at a low latency timing of 16-18-18

at 1.2V. Additional timing parameters are shown in the

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.
