HyperX HX424C12SB2K4/16 is a kit of four 512M x 64-bit (4GB) DDR4-2400 CL12 SDRAM (Synchronous DRAM) 1Rx8, memory modules, based on eight 512M x 8-bit FBGA components per module. Total kit capacity is 16GB. Each module supports Intel XMP (Extreme Memory Profiles). Each module has been tested to run at DDR4-2400 at a low latency timing of 12-14-14 at 1.35V. The SPDs are programmed to JEDEC standard latency DDR4-2133 timing of 15-15-15 at 1.2V. Each 288-pin DIMM uses gold contact fingers.
