Corsair Vengeance LPX 32 GB (4x8GB DDR4-2666)

The Corsair Vengeance LPX 32 GB ships as 4 modules of 8GB each with 32GB of DDR4 on board. It is rated at 2666 MT/s with a CAS latency of 15, working out to a true latency of about 11.3ns. Operating voltage sits at 1.35V. 32GB gives you enough headroom for gaming plus heavy multitasking and content work; past 3600 MT/s, extra frequency brings diminishing returns.

Builders shopping for older AM4 and LGA1700 boards that top out at DDR4 will find this high-end DDR4 option easy to justify. Its $189.00 price tag places it squarely in high-end territory.
