DESCRIPTION
HyperX HX426C15FB/8 is a 1G x 64-bit (8GB) DDR4-2666 CL15
SDRAM (Synchronous DRAM) 2Rx8, memory module, based on
sixteen 512M x 8-bit FBGA components per module. Each module
kit supports Intel® Extreme Memory Profiles (Intel® XMP)
2.0. Each module has been tested to run at DDR4-2666 at a low
latency timing of 15-17-17 at 1.2V. Additional timing parameters
are shown in the Plug-N-Play (PnP) Timing Parameters
section below. The JEDEC standard electrical and
mechanical specifications are as follows:
FEATURES
• Power Supply: VDD = 1.2V Typical
• VDDQ = 1.2V Typical
• VPP - 2.5V Typical
• VDDSPD = 2.2V to 3.6V
• Nominal and dynamic on-die termination (ODT) for
data, strobe, and mask signals
• Low-power auto self refresh (LPASR)
• Data bus inversion (DBI) for data bus
• On-die VREFDQ generation and calibration
• Dual-rank
• On-board I2 serial presence-detect (SPD) EEPROM
• 16 internal banks; 4 groups of 4 banks each
• Fixed burst chop (BC) of 4 and burst length (BL) of 8
via the mode register set (MRS)
• Selectable BC4 or BL8 on-the-fly (OTF)
• Fly-by topology
• Terminated control command and address bus
• Height 1.340” (34.04mm), w/heatsink
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.

All Kingston products are tested to meet our published specifications. Some motherboards or system configurations may not operate at the
published HyperX memory speeds and timing settings. Kingston does not recommend that any user attempt to run their computers faster than
the published speed. Overclocking or modifying your system timing may result in damage to computer components.
