Lol @LinusTech, what is this...
You cannot fit in a dual channel kit of ram in this video for a budget of $300.
Here is a build with r3 2200g and 16gb "dual channel" 3200mhz ram. Took me like a minute to put this together.
Ryzen loves fast dual channel memory. I know that 3000g is limited upto 2666mhz speed, but you could at least get a 2666mhz 2*4gb kit. It would be a significant upgrade over the rig that you have got.
