SPECIFICATIONS *Power will vary depending on the SDRAM used. HX426C16FB2/8 8GB 1G x 64-Bit DDR4-2666 CL16 288-Pin DIMM Continued >> kingston.com/hyperx FEATURES HyperX HX426C16FB2/8 is a 1G x 64-bit (8GB) DDR4-2666 CL16 SDRAM (Synchronous DRAM) 1Rx8, memory module, based on eight 1G x 8-bit FBGA components per module. Each module 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 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: CL(IDD) Row Cycle Time (tRCmin) Refresh to Active/Refresh Command Time (tRFCmin) Row Active Time (tRASmin) Maximum Operating Power UL Rating Operating Temperature Storage Temperature 16 cycles 45.75ns(min.) 350ns(min.) 29.25ns(min.)
