8GB 1G x 64-Bit DDR4-2666 CL15 288-Pin DIMM

SPECIFICATIONS

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. kit supports Intel® Extreme Memory Profiles (Intel® XMP)

Each module has been tested to run at DDR4-2666 at a low

2.0. latency timing of 15-17-17 at 1.2V. are shown in the Plug-N-Play (PnP) Timing Parameters section below. The JEDEC standard electrical and mechanical specifications are as follows:

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.
