Seems like a good deal for 32GB of RAM. I am in the market for DDR3 - but thought I would post this whilst I saw it!
HyperX HX430C15PB3K2/8 is a kit of two 512M x 64-bit (4GB) DDR4-3000 CL15 SDRAM (Synchronous DRAM) 1Rx8, memory module, based on eight 512M x 8-bit FBGA components per module. Each module kit supports Intel Extreme Memory Profiles (Intel XMP) 2.0. Total kit capacity is 8GB. Each module has been tested to run at DDR4-3000 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
