DESCRIPTION
FEATURES
HyperX HX428C14SBK2/16 is a kit of two 1G x 64-bit (8GB)
DDR4-2800 CL14 SDRAM (Synchronous DRAM) 2Rx8, memory
modules, based on sixteen 512M x 8-bit FBGA components per
module. Total kit capacity is 16GB. Each module supports
Intel® XMP (Extreme Memory Profiles). Each module has
been tested to run at DDR4-2800 at a low latency timing of
14-15-15 at 1.35V. The SPDs are programmed to JEDEC
standard latency DDR4-2133 timing of 15-15-15 at 1.2V.
Each 288-pin DIMM uses gold contact fingers. The JEDEC
standard electrical and mechanical specifications are as
follows:
• 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 1.36” (34.57mm)
XMP TIMING PARAMETERS
•JEDEC: DDR4-2133 CL15-15-15 @1.2V
•XMP Profile #1: DDR4-2800 CL14-15-15 @1.35V
•XMP Profile #2: DDR4-2666 CL14-14-14 @1.35V
