DESCRIPTION Hyper X HX421S14IBK4/32 is a kit of four 1G x 64-bit (8GB) DDR4-2133 CL14 SDRAM (Synchronous DRAM) 2 Rx 8, memory modules, based on sixteen 512M x 8-bit DDR4 FBGA components. Total kit capacity is 32GB. 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 Pn P Timing Parameters section below. The JEDEC standard electrical & mechanical specifications are as follows: Pn P JEDEC TIMING PARAMETERS: JEDEC/ Pn P: DDR4-2133 CL14-14-14 @1.2V DDR4-1866 CL13-13-13 @1.2V XMP Profile 1: DDR4-2133 CL14-14-14 @1.2V SPECIFICATIONS CL (IDD) 14 cycles Row Cycle Time (t R Cmin) 46.5ns (min.)
