DDR4 3200 vs slower for a ryzen rendering machine?

[r4sh1d]

I'm building a pc for my wife for her school graduate projects (3ds max design, Vray, tons of rendering, Photoshop & Sketchup.).

I grabbed a 1700 and plan on overclocking it to 3.8 hopefully. I'll be buying a Gigabyte AB350M-GAMING 3 and will need a 2X16GB kit.

Assuming in the QVL list, would I see a difference between 3200 vs 2666 vs slower 2400?

For example, I can get this for $190 elsewhere

Or should I pay $40 more for this?

Based on Legitreview, there's a difference. But does it matter if the machine is NOT going to be used for gaming?

pugetsystems has an old review (2013 I think) and it showed that it doesn't affect productivity software that much.

Edit: I understand that since 2X16GB kits are going to be dual rank, I'll be limited to 2400 speeds anyway, at least for the time being; correct? Is it worth it to spring more $$ for higher speed RAM now?
Thanks!

Unless you go for some single rank ram i would not count on going much over 2400-2666 speeds.

Thanks for the input, just hate that the prices were lower a few months back for DDR 4 32GB!

Right - and aren't almost all 16GB chips dual-ranked?

I'm not sure if Ryzen "does better" with 2x16GB dual rank vs 4x8GB single ranked.

Yeah thats a tough one, dual rank 2 dimms vs single rank 4 dimms.

Time will tell i guess.

Pretty sure all 16GB modules are dual ranked.

If I remember correctly AMD PR docs said 2 dual ranked modules would work at faster speeds compared to 4 single ranked. 2400 vs 2133.
