32GB RAM helps compile times if you're running out.

Yes, but only if your current setup is causing swapping. Compilation is mostly CPU-bound, but linking and parallel builds can eat memory fast.

Large C++ projects in Visual Studio can chew through 16GB during a full rebuild. If your system starts paging to disk, your compile time goes from minutes to hours. Adding 32GB eliminates that bottleneck.

But if you already have 16GB and you’re not hitting swap during builds, more RAM won’t make your CPU compile any faster. Check Task Manager during a build. If memory usage stays below 80%, 32GB is a waste for this specific task.

Don’t upgrade until you’re sure memory is the problem.
