Memory needs to be fast as it directly affects the speed of the processor(or, at least, its rendering times in Corona, which is all that matters to me), and you need to check its been tested with your motherboard (Check the manufacturers QVL lists for tested ram and pick from there, should be found on their websites and lists ram that they have actually tested with the motherboard).
Hi, are there any benchmarks or test/comparisons to support this? When you say speed of memory is it timings or the actual frequency? A friend of mine tested cinebench scores of 2990wx at different memory frequencies and the results were completely negligible
I am also about to build a 2990wx rig for rendering so don't want to waste money on expensive RAM modules unnecessarily
Thanks for the info.
