Yes, but only if your assemblies are actually large enough to need it.

SolidWorks keeps a lot of data in memory—geometry, mates, configurations, feature history. If your assemblies regularly exceed 3,000–5,000 unique parts, or you’re running complex simulations alongside, 32GB can swap to disk and your machine starts crawling.

64GB won’t make simple assemblies faster. It’s a headroom play, not a speed boost. If you find yourself waiting minutes for opens or rotates to respond, check your RAM usage in Task Manager. If it’s pegged near 100%, 64GB is the fix.

But don’t skip the CPU or GPU. SolidWorks still relies on single-core clock speed for most modeling tasks, and a professional GPU (not a gaming card) makes a bigger difference in some views. RAM is only the bottleneck if it’s actually full.

Your mileage may vary, but if you’re hitting the limit, 64GB is a worthy upgrade.
