Thermaltake TOUGHRAM XG RGB 64 GB (2x32GB DDR4-4000)

The Thermaltake TOUGHRAM XG RGB 64 GB ships as 2 modules of 32GB each with 64GB of DDR4 on board. It is specced for 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.

Once memory clears 3600 MT/s, frequency gains taper off, so the 64GB on offer here is the spec that counts for gaming plus heavy multitasking and content work. DDR4 pricing in the premium tier makes this a sensible pairing for older AM4 and LGA1700 boards that top out at DDR4. Expect to pay around $549.99, which lands it among premium options.
