Thermaltake TOUGHRAM RC 16 GB (2x8GB DDR4-4000)

The Thermaltake TOUGHRAM RC 16 GB comes as 2 modules of 8GB each with 16GB of DDR4 on board. Operating voltage sits at 1.35V. It is rated at 4000 MT/s with a CAS latency of 19, working out to a true latency of about 9.5ns. 16GB gives you enough headroom for modern AAA titles; 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 $159.99 price tag places it squarely in high-end territory.
