DESCRIPTION
FEATURES
HyperX HX421S13IB/4 is a 512M x 64-bit (4GB) DDR4-2133 CL13
• Power Supply: VDD = 1.2V Typical
SDRAM (Synchronous DRAM) 1Rx8, memory module, based on
eight 512M x 8-bit DDR4 FBGA components. Each module
• VDDQ = 1.2V Typical
supports Intel® Extreme Memory Profiles (Intel® XMP) 2.0. This
• VPP - 2.5V Typical
module has been tested to run at DDR4-2133 at a low latency
• VDDSPD = 2.25V to 3.6V
timing of 13-13-13 at 1.2V. Additional timing parameters are
• On-Die termination (ODT)
shown in the PnP Timing Parameters section below. The JEDEC
standard electrical and mechanical specifications are as follows:
• 16 internal banks; 4 groups of 4 banks each
• Bi-Directional Differential Data Strobe
• 8 bit pre-fetch
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.
• Burst Length (BL) switch on-the-fly BL8 or BC4(Burst Chop)
• Height 1.18” (30.00mm)
PnP JEDEC TIMING PARAMETERS:
• JEDEC/PnP:
DDR4-2133 CL13-13-13 @1.2V
• XMP Profile #1:
DDR4-2133 CL13-13-13 @1.2V
