Read MT/s and CAS latency when comparing the profiles. Match capacity to the workload and use one suitable channel/kit arrangement rather than buying on a speed label alone.

Buy enough memory for the work first, then choose the speed and physical fit. I’d start a modern gaming or work build at 32GB, move to a matched 64GB kit for larger creative projects, and consider 96GB when editing or rendering genuinely needs it. Keep AM4 DDR4 separate from AM5 DDR5.

Capacity solves a different problem from speed. When the working set no longer fits in RAM, the PC has to move data through storage and responsiveness can suffer. A faster 32GB kit does not turn into 64GB. For an editing workstation with several applications open, useful capacity deserves the first share of the memory budget.

Choose the purpose below for the direct shortlist. Each section also links to its detailed buying guide and the complete matching PC build. If you are starting from an empty desk, use the beginner’s complete PC guide first.

Add a catalogue DDR5 kit to an AM5 tower in PC Builder and compare the estimated complete-build cost alongside the capacity advice here.

I’d start the serious editing route at 64GB, and examine 96GB for heavier 4K projects or work shared with After Effects. Puget’s current Premiere recommendations are substantially higher than the old assumption that every 4K editor needs only 32GB. Capacity should follow the timeline, codecs and applications, rather than the resolution printed in a generic parts-list title.

For a mixed Blender workstation I’d choose 64GB, with 32GB as the smaller-scene learning route. Geometry, simulation caches and the other creative applications all need system memory. This is separate from GPU VRAM: installing more DDR5 does not turn a 16GB graphics card into a 32GB one. Keep both capacities visible when planning a large scene.

For an everyday work PC, I’d choose a matched 32GB kit and stop there unless the applications say otherwise. It gives useful room for a browser, meetings and ordinary productivity work without turning the office basket into a workstation memory project. A premium RGB kit is a visual choice, not a requirement for a spreadsheet or video call.

In a compact air-cooled build, I’d choose the memory alongside the cooler. The 32GB Crucial route is the starting point; a matched 64GB kit is useful for the creative version. The important physical measurement is the installed module height and the cooler’s front fan, because lifting that fan can turn a nominally suitable heatsink into a side-panel problem.
