SPECIFICATIONS
DESCRIPTION
HyperX HX426C15FB/4 is a 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.
kit supports Intel® Extreme Memory Profiles (Intel® XMP)
Each module has been tested to run at DDR4-2666 at a low
2.0.
latency timing of 15-17-17 at 1.2V.

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.
