2 versus 4 units with 64GB RAM for the 3900x processor
I’m evaluating the upgrade options for your system. You’re considering two G.Skill configurations: one with four 16GB modules at 3600 CL16 and another with two 32GB modules at 3600 CL18. Some advice suggests that adding more RAM might put extra load on the memory controller or limit performance gains. Based on typical performance trends, the four-module setup could offer better stability and potentially higher sustained speeds compared to the dual-32GB configuration. However, your specific use case with an Asus Crosshair 8 Wifi Mobo matters—consider workload demands and thermal management. It might be wise to test both configurations under real conditions to see which delivers the best results for your needs.
I would say, just grab the two 32gb units, yes, that's correct. Using four sticks would put more strain on the memory controller. With two sticks, you can overclock more effectively and achieve better stability.
When adjusting memory manually, using two sticks performs better than four. If you only turn on XMP and never revisit memory settings, four sticks will be slower.
It will. Not only are the timings tighter, but it should benefit from being quad rank while 2x32gb is only dual rank (unless it's the stacked kit which is super tall, but those barely appear in the market) It's also because people want to pair those older CPUs with 16gb memory (so 2x8gb). I doubt anyone still on AM4 will need more than 32GB when DDR5 becomes popular.
