DESCRIPTION

HyperX HX426C15PB3K2/64 is a kit of two 4G x 64-bit (32GB)

DDR4-2666 CL15 SDRAM (Synchronous DRAM) 2Rx8, memory

module, based on sixteen 2G x 8-bit FBGA components per module.

Each module kit supports Intel® Extreme Memory Profiles (Intel®

XMP) 2.0. Total kit capacity is 64GB. Each module has been tested

to run at DDR4-2666 at a low latency timing of 15-17-17 at 1.35V.

The SPDs are programmed to JEDEC standard latency DDR4-2400

timing of 17-17-17 at 1.2V. Each 288-pin DIMM uses gold contact

fingers. The JEDEC standard electrical and mechanical

specifications are as follows:
