Video editing is one of the few tasks that genuinely eats memory, especially once you stack 4K timelines, colour grades and effects. For SA creators, the right RAM amount is the difference between a smooth scrub and a spinning cursor.
Quick Answer
For 1080p and light 4K editing, 32GB of DDR5-6000 is the practical floor, while serious 4K and multi-stream timelines want 64GB. On a R80,000 build, 32GB DDR5-6000 CL30 keeps Premiere and DaVinci Resolve responsive, and a fast NVMe scratch disk matters as much as the RAM itself.
RAM Targets By Editing Resolution
1080p projects run fine on 32GB; 4K with multiple streams, lots of effects or motion graphics pushes toward 64GB. DaVinci Resolve in particular leans on both system RAM and GPU VRAM, so 32GB plus a card with 12GB or more VRAM is a balanced pairing. A R80,000 plan should buy a 2x16GB DDR5-6000 kit now, with two slots free for a clean step to 64GB.
Storage Speed Is The Hidden Half Of Editing
RAM holds the active timeline, but a fast NVMe Gen4 SSD (5,000MB/s or faster) is what stops playback stutter when scrubbing 4K footage. Keep media, cache and the OS on separate drives so the editor is not reading and writing to the same disk. Without quick storage, extra RAM alone will not fix laggy 4K scrubbing.
GPU And CPU Share The Load With RAM
Resolve offloads colour and effects to the GPU, while Premiere leans on the CPU and RAM for playback. DDR5-6000 CL30 on AM5 keeps the pipeline fed, and matched dual-channel sticks are essential since single-channel memory throttles render and playback alike. Buy the capacity first, then the speed.
FAQ
How much RAM for 4K video editing?
64GB is the comfortable target for serious 4K work with effects and multiple streams, while 32GB handles 1080p and light 4K. Pair the RAM with a fast NVMe scratch disk to avoid playback stutter.
Is 16GB enough for video editing?
Only for short 1080p clips with few effects. Modern editors and 4K footage quickly exceed 16GB, so 32GB is the realistic minimum for a smooth experience in Premiere or DaVinci Resolve.
Does my GPU or RAM matter more for editing?
Both, in different stages. DaVinci Resolve leans heavily on GPU VRAM for grading and effects, while playback and caching lean on system RAM. A balanced rig pairs 32GB or more with a 12GB+ VRAM card.
