Great post.

How much is difference between DDR4 2666MHz and SO-DIMM DDR4 2666MHz.
Now precisely, approximately 10-20% better performance. 

I wonder if I should upgrade to 32gb 3000+MHz soon, I'm currently sitting on 16gb 2800 MHz but RAM needs have been getting steadily higher, especially with infinity fabric that gives a decent boost to performance.

I don't have resources now. I need to pay 350 euro for watercooling.
But that's parts without any waterblock. Because I have Monoblock and GPU cooling will be build on Summer.
Can you imagine 350 euro, pump-res, radiator, fittings, adapters.
 
And I really don't have 400 euro for 32GB od Dominator Platinum while computer use half of 16GB max.
I plan to update platform when DDR5 show up and than I will go immediately on 32-64GB.

thank you for this informative post

Quality thread for sure finally learned what some of those abbreviations mean

Now that you mention it that's probably the path I'll take too. Why get DDR4 when DDR5 is on the horizon and is rumored to boast a 2x increase in speed.

Thanks for the help. Finally understand it a little better. 

I would disagree with some of that graph. I haven't seen a game yet that can't run properly on ultra settings with 8gb of RAM.

Very good info.
I had a problem where I upgraded my ram and my video card stopped working. Have you ever heard of that? I am starting to dive into researching it but wondered if anyone ever heard of that.
