16GB helps, but it’s not a magic fix for microstutters.

Yes, 16GB can reduce microstutters on an older CPU like the i5-8400, but don’t expect it to solve everything.

Modern games are RAM hogs. 8GB is borderline, and when your system runs out of physical memory, it starts swapping to disk. That causes sudden hitches—exactly the kind of microstutter you’re trying to kill. 16GB gives you breathing room so the OS isn’t constantly fighting for free pages.

But the i5-8400 itself can be a bottleneck in CPU-heavy scenes, especially at low settings or high frame rates. RAM won’t fix that. Also, a slow hard drive or background apps chewing up resources can cause stutters regardless of capacity.

So: upgrade to 16GB if you’re still on 8GB. Just know it’s a solid improvement, not a cure-all.

Check your pagefile usage in Task Manager before buying. If it’s sitting at 90%+ during gaming, that’s your culprit.
