Hey all :)

So I’m planning on building another PC this holiday season. I do a lot of video editing in Adobe After Effects aswell as 3D modeling in Cinema 4D.

I’ve read a lot of benchmarks comparing render speeds in after effects based on how much ram you have.

I’m planning on building my PC with an i7 7700k and initially installing 16gb of G-Skill Trident RGB ram. However, I’m wanting to buy a second kit of 16 GB down the road in order to increase my render speeds and have a total of 32GB.

I know that there is a risk with mix-matching kits of ram and the fact that they might not work but I’d rather do that than spend 2x as much money right now.

But my question is, the 7700k has a “Dual channel memory controller”. So how many sticks of ram can I use with this cpu then?

MOBO: ASRock SLI killer Z270

Go with the 8700k instead. A better cpu can help render speed more than RAM.
Now to answer the question, on a dual channel board, running dual channel RAM is always more optimal. But it does not have much effect on render speed. You can start with 2x8gb and then add another set of it down the line. Ofcourse mixing RAM is a 50-50 proposition, but it does work most of the times if you go with a similar set of kit. More of a trial and error thingy here.

You can use as many modules as you have sockets. In your case, 1 to 4. I will run in in single channel mode, 2 or 4 will run in dual channel mode. Three modules will depend on the processor you are using. I think the 770k supports "flex mode" bit I might be wrong. In Flex mode you would get 2 modules running in dual channel mode and one module running in single channel mode. In the case of 4 modules, you'll have two dual channels.

Each module has a 64-bit wide bus to the memory controller in the CPU. But Dual channel makes that appear to be 128-bits wide to the memory controller so it can read/write 128 bits at a time.

You can use as many as the motherboard supports. If you have 4 slots for memory on a dual-channel motherboard, that means you could have 2 sets of dual-channel memory at the same time. *(2 sticks make up dual-channel)

Get the same exact memory when you get the second set and you should be fine. Some say it may not work, but there is a very small chance that it won't work.

Also, I don't think more memory would help with render speed. It may prevent lag when editing if you're using all 16GB, but rendering time wouldn't be affected.
