Generally, the faster the RAM, the faster the processing speed. With faster RAM, you increase the speed at which memory transfers information to other components. Meaning, your fast processor now has an equally fast way of talking to the other components, making your computer much more efficient.

Does memory affect speed?

Memory affects computer speed because the CPU must move information into memory and retrieve data from it when running applications. If you have a lot of memory, the CPU can move larger chunks of it faster.

Will RAM help a slow computer?

The operating system relies heavily on RAM for smoothly running tasks. Not having enough RAM for the processes you're trying to run can tellingly cause your computer to slow down.
