I'm in the process of upgrading my older PC build using a mix of new, existing, and traded components. Currently, I have a choice between using my 16GB (2x8) DDR4-2133 RAM or my 16GB (2x8) DDR4-3200 RAM. My motherboard can support all four sticks, but I'm debating whether it's better to run the faster 3200MHz sticks alone for a total of 16GB or use all four sticks for 32GB at a slower speed. My usage includes casual gaming at 1080p and some 3D CAD work, along with games like Skyrim and Borderlands 2, and I'm looking to give Helldivers 2 a shot in the future. I'd love to hear your advice!

Your power supply is also a key factor here. If it’s old, it might struggle with all that hardware, especially during heavier workloads. Just a little heads-up!
It really depends on what you need for your workloads. If you're mainly gaming and doing some 3D work, 16GB might be enough. But if you notice your RAM usage is maxing out, you might benefit from the extra capacity, even if it runs at a slower speed. Monitor your usage while gaming and working to get a better idea!
Exactly! If you find that your RAM isn't nearing its limits during your typical use, sticking with the faster sticks could be the way to go.
In real-world use, running the faster two sticks should give you better performance for most tasks. For gaming, dual-channel setup typically suffices, and four mismatched sticks might not be worth the hassle unless you're really pushing the limits of capacity.
Right! Most consumer setups hit a ceiling with dual-channel, so matching speeds is less critical unless you’re gaming at extremely high settings.

Haha, it's been around since I built this rig in 2016! Definitely something to consider moving forward.
