HyperX HX421S13IB/8 is a 1G x 64-bit (8GB) DDR4-2133 CL13
SDRAM (Synchronous DRAM) 2Rx8, memory module, based on
sixteen 512M x 8-bit DDR4 FBGA components. Each module
supports Intel® Extreme Memory Profiles (Intel® XMP) 2.0.
This module has been tested to run at DDR4-2133 at a low
latency timing of 13-13-13 at 1.2V. Additional timing parameters
are shown in the PnP Timing Parameters section below. The
JEDEC standard electrical and mechanical specifications are as
