Thermaltake TOUGHRAM XG RGB 32 GB (2x16GB DDR4-4000)

The Thermaltake TOUGHRAM XG RGB 32 GB ships as 2 modules of 16GB each with 32GB of DDR4 on board. It is rated at 4000 MT/s with a CAS latency of 19, working out to a true latency of about 9.5ns. 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.

As a high-end DDR4 kit, it slots naturally into older AM4 and LGA1700 boards that top out at DDR4. At $175.99 it sits in the high-end memory kit bracket. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current memory kit prices across retailers.
