Solved Matching ram to mobo and cpu

September 15, 2018 at 17:08:12
Specs: Windows 7 x64, 32GB
just acquired a asus x99 deluxe with i7 5820k
I have other parts to get it up and running except ram
I was thinking g.skill 2400mhz 16gb
4x4gb or 2x8gb,which is better?

but then checking on 5820k specs I see it's DDR4 1600/1866/2133
so now I'm thinking I need to get 2133mhz ram to run in tune with the cpu?

I will be trying to overclock sooner rather than later does mhz make a difference?

Is there a sweet spot of ram for this combo?

✔ Best Answer
Both the CPU & board officially support DDR4 2133MHz. The board also supports 2400MHz thru 3200MHz by overclocking so if you intend to overclock the CPU, you should get RAM rated higher than 2133MHz. Also, the board & CPU supports quad channel so 4 x 4GB would probably be the best way to go. If you look at the benchmarks in the article below, it really doesn't make that huge a difference, but as the reviewer said, "there’s just no reason to give it up".
