HyperX HX426C16FB2/8 is a 1G x64-bit (8GB) DDR4-2666 CL 16 SDRAM (Synchronous DRAM) 1Rx8, memory module, based on eight 1G x 8-bit FBGA compnents per module. Each module supports Intel Extreme Memory Profiles (Intel XMP) 2.0.Each module has been tested to run at DDR4-2666 at low latency timing of 16-18-18 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.
