DESCRIPTION

HyperX HX421S14IBK4/16 is a kit of four 512M x 64-bit (4GB)
DDR4-2133 CL14 SDRAM (Synchronous DRAM) 1Rx8, memory
modules, based on eight 512M x 8-bit DDR4 FBGA components.
Total kit capacity is 16GB. Each module kit 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
14-14-14 at 1.2V. Additional timing parameters are shown in the
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.

PnP JEDEC TIMING PARAMETERS:

• JEDEC/PnP: DDR4-2133 CL14-14-14 @1.2V
DDR4-1866 CL13-13-13 @1.2V

• XMP Profile #1: DDR4-2133 CL14-14-14 @1.2V

FEATURES

• Power Supply: VDD = 1.2V Typical

• VDDQ = 1.2V Typical

• VPP - 2.5V Typical

• VDDSPD = 2.25V to 3.6V

• On-Die termination (ODT)

• 16 internal banks; 4 groups of 4 banks each

• Bi-Directional Differential Data Strobe

• 8 bit pre-fetch

• Burst Length (BL) switch on-the-fly BL8 or BC4(Burst Chop)

• Height 1.18” (30.00mm)
