DESCRIPTION
HyperX HX426C15FBK2/8 is a kit of two 512M x 64-bit (4GB)
DDR4-2666 CL15 SDRAM (Synchronous DRAM) 1Rx8, memory
module, based on eight 512M x 8-bit FBGA components per
module. Each module kit supports Intel® Extreme Memory
Profiles (Intel® XMP) 2.0. Total kit capacity is 8GB. Each
module has been tested to run at DDR4-2666 at a low latency timing
of 15-17-17 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.
