Exterior of video games and common looking, skilled purposes are likely to hog essentially the most RAM.

The quantity on the finish notes the reminiscence’s velocity. The good thing about sooner reminiscence is easy: Extra cycles per second means the module can learn and write knowledge sooner.

It’s not so simple as shopping for RAM sticks with the next quantity, although. DDR4 reminiscence modules are all rated to run at 2133MHz, and it doesn’t matter what modules you purchase or what they’re rated for, they’ll run at 2133MHz out of the field. That presents an issue in case you purchased reminiscence rated for 3200MHz. The velocity your RAM is rated for is simply that: a score.
