Hi, all. I am new to building computers and am currently working on a high-end build for both gaming and prime crunching (with Fermat probability testing). Large amounts of RAM are helpful for a "pre-testing" phase of these Fermat tests with more = better. However, it is my understanding that increasing RAM to four sticks from two nearly invariably reduces speed by a large amount. Are there motherboards that are more optimized for four sticks of RAM? I have my eye on the new 28 CL 2x48GB 6,000 Royal Neo. However, I assume I would not want two of these kits and that when four sticks of RAM are used they should be purchased as a kit of four rather than two kits of two. If it helps, I am likely getting the 9800x3d for my CPU. Thanks!
