I need a really good large RAM for a PC I want to get built meant to render Blender Cycles.


  • Compatibility with the MSI X399 board.
  • Compatibility with the (non-OC'ed) AMD Ryzen Threadripper 1950X.
  • No more than 4 modules with a combined capacity of 32GB.
  • Price preferably 300 USD or lower
  • The next up on the list of Hardware to specify is the case and then only the CPU cooler is left and you are (finally) done :)

It turns out that finding 4x8GB of DDR4 RAM with 2666 transfer speed for 300USD or less is impossible. However, I barely found this RAM, the G.Skill Ripjaws 4 2400 32GB for 300USD.

  • It is compatible with the board and CPU listed (which both easily support this RAM speed)
  • It is within the appointed budget of 300USD.
  • Reviews of higher-clocked variants appear to look good for this series of RAM
  • Being 4x 8GB it can make use of the 4 memory channels of the Threadripper
  • With 15 cycles of delay, it's not the lowest-latency RAM but it should easily do the job
