DESCRIPTION FEATURES Power Supply: VDD = 1.2V Typical HyperX HX421C14FB/8 is a 1G x 64-bit (8GB) DDR4-2133 CL14 VDDQ = 1.2V Typical SDRAM (Synchronous DRAM) 2Rx8, memory module, based on VPP - 2.5V Typical sixteen 512M x 8-bit FBGA components per module. Each module VDDSPD = 2.2V to 3.6V kit supports Intel Extreme Memory Profiles (Intel XMP) Nominal and dynamic on-die termination (ODT) for 2.0. Each module has been tested to run at DDR4-2133 at a low data, strobe, and mask signals latency timing of 14-14-14 at 1.2V. Additional timing parameters Low-power auto self refresh (LPASR) are shown in the Plug-N-Play (PnP) Timing Parameters Data bus inversion (DBI) for data bus section below. The JEDEC standard electrical and On-die VREFDQ generation and calibration mechanical specifications are as follows: Dual-rank On-board I2 serial presence-detect (SPD) EEPROM 16 internal banks 4 groups of 4 banks each Note: The PnP feature offers a range of speed and timing options to support the widest variety of processors and chipsets.
