Quick Answer
For Adobe Premiere Pro, DDR5 capacity beats DDR5 speed every time: 32GB is the practical floor and 64GB is the real upgrade for 4K timelines. A 64GB DDR5-6000 kit at Evetech sits around R2,800 to R4,500, and that capacity jump matters far more than chasing 7200 MT/s.
Why Capacity Wins For Premiere Pro
Premiere holds source footage, previews and effect caches in memory, so it fills RAM fast on multi-layer 4K sequences. On 16GB you will see playback drops and constant cache flushing the moment you stack Lumetri, warp stabiliser and a few adjustment layers. Move to 32GB and most 1080p and light 4K work runs cleanly; jump to 64GB if you edit long-form 4K, multicam or heavy After Effects round-trips.
A 6000 MT/s CL30 kit is plenty. Editing is bandwidth-light compared with capacity-hungry, so a 64GB DDR5-5600 kit at the right price beats a 32GB DDR5-7200 kit for this workload.
SA Buyer Notes
On AM5 (Ryzen 7 9700X, 9800X3D) stick to a 6000 MT/s kit so the controller stays 1:1; Intel Core Ultra editing rigs tolerate 6400 MT/s comfortably. Budget roughly R1,400 to R2,200 for 32GB and R2,800 to R4,500 for 64GB at current Evetech pricing. Pair the RAM with a fast NVMe scratch disk, because slow storage will bottleneck your timeline long before memory speed does.
FAQ
Is 32GB enough for Premiere Pro in 4K?
For short 4K clips and 1080p projects, yes. For long-form 4K, multicam or After Effects work, 64GB removes cache thrashing and keeps playback smooth, so heavier editors should plan for it.
Does DDR5 speed matter for video editing?
Capacity matters far more. A 6000 MT/s kit is ideal; spending extra on 7200 MT/s gives almost nothing in Premiere compared with adding more gigabytes.
Should I run four sticks or two for editing?
Two sticks of 32GB run cleaner and hit rated speed more reliably than four sticks. If you may go to 64GB later, buy a matched 64GB kit upfront rather than mixing.
Confirm your platform takes 64GB and add a matched DDR5-6000 kit at Evetech before your next 4K project so Premiere stops flushing cache mid-edit.
