ddr4 for a 5960x build

[stag3]

is the price premium worth it for ddr4 3200?
or is there a sweet spot like the 3000 or 2800?
i'll be running 4x4gb, most likely mushkin redline

looks like most of the 3000 and up are cas 16 and higher + 1.35v
and the 2800's are cas 15, not that you can notice it

i guess my main question is what is the optimal ram to purchase if i'll be o/c to ~4.0-4.2 ghz

there is some 3000mhz 15-15-15-35 1.35v kits for $155 from g.skill and mushkin that look good to me

It might be with 3-way or 4-way SLI/crossfire...

2400MHz, 1.2V. With the four channels, even CPU OCing >4GHz isn't going to net you any need for fast RAM. It won't hurt, just won't get you much, if anything.

The bigger the capacity, the higher the speed. That's what the ORIGIN PC Tech department told me when I was building my system. I asked why can't I choose 2666 or 2800 MHz if I configure my system with 64 GB RAM, they told me the sweet spot for 64GB is 2400 MHz with the XMP profile or for 32 GB you can do 2666 MHz and for 16 GB you can do 2800 MHz
