FEATURES
FURY KF426C16BBK4/128 is a kit of four 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 128GB. 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. Each 288-pin
DIMM uses gold contact fingers. The JEDEC standard
electrical and mechanical specifications are as follows:
