Hi there,
I'm trying to build a PC for game development and mostly using Unity and Unreal plus some minor 3D software. I know 13900K is a good CPU for build and compiling of game projects but in memory terms I have no Idea which one should I choose. I don't like overclocking the system but I like to use XMP.
So I've chosen a Corsair dominator 32*2 5600 but the retailer suggest using the 5200 one. he mentioned the higher frequency memories are not as stable as 5200 and may face blue screens and crashes. So I'm asking if he is right or should I get the 5600. Also the mainboard I chose is Asus prime a wifi d5.
Thanks
