What it is and What it Does

Intel invented the first RAM chip, the Intel 1103 in 1970. They had started work on it in 1969. It was only 1 KB. You can read more about the invention of the Intel 1103 Here.

RAM allows for you to multitask. RAM does not speed up single task. RAM stores memory the CPU needs to retrieve quickly. The speed of the RAM is how quickly the RAM stores and retrieves this memory. RAM timing is the Latency of the RAM. The Lower the number for RAM timings the lower the latency.


How it affects APUs

An APU is an Accelerated Processing Unit. Recently AMD released Ryzen APUs. APU have discrete graphic cores. RAM is very important to get right with the APU. In the Case of APUs you want a higher speed if it is all you'll be gaming on for awhile. A higher speed will get you a higher frame rate in games on APUs. However if your going to game on a GPU, there is no need to get a higher speed of ram.

RAM and Video Editing

RAM does not affect the Rendering Speed for video editing. Those are bound to your CPU and GPU. The More RAM you have though does affect how you’ll be able to work. If you want work with just 1080 p then 16 GIGs is enough. 4k just 32 GB is all that is needed.


RAM and Video Games

Video Games do need RAM and as the years have gone the days of getting by with 4GB are long gone. The minimum now is 8GB but I honestly wouldn’t be surprised if it goes to 16 GB. Why would you need so much?

I personally have 32 cause I do video editing. However I’m also a ReShade Expert and user. For those you that doesn’t know ReShade is a Shading tool for Games. That’s the simple version. Anyway it runs with in the game so by me having more RAM allows my work with ReShade to go a lot easier.

Consider the fact: When your gaming on PC, your typical launching the game by Steam or Origin or GOG. These Launchers are running in the background and have overlays. These use RAM.


Getting the Right RAM for your motherboard or laptop

Before you buy RAM, you need to check to see if it is compatible with your motherboard or laptop. Just cause your Motherboard takes DDR4 RAM does not mean it will work with all DDR4 RAM.

Crucial, G-Skill, and Corsair have tools to search for RAM by Motherboard. Doing this will allow to find ram that works for your motherboard.

There is an older guide on GURU3D forums you can also read. It is from 2004 but the information in it is still relevant in ways.

Hardware Canucks Video: 16 GB vs 32 GB vs 64 GB RAM is a good video showing how ram affects gaming and video rendering.
