DESCRIPTION
HyperX HX426C16FB3 is a 512M x 64-bit (4GB) DDR4-2666
CL16 SDRAM (Synchronous DRAM) 1Rx8, memory module, based
on eight 512M x 8-bit FBGA components per module. Each
module supports Intel® Extreme Memory Profiles (Intel®
XMP) 2.0. 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: FACTORY TIMING PARAMETERS
