5 Reasons 64GB RAM Is Overkill for a Plex Transcoding Server

Hardware transcoding uses the GPU, not RAM Hardware transcoding shifts the heavy lifting to your GPU or iGPU. RAM does not handle video encoding, so extra RAM won’t improve transcoding performance.

Plex rarely needs more than 8GB total Even during multiple simultaneous 4K transcodes, Plex typically uses under 8GB of RAM. Servers with 16GB often sit at 30% utilization under load.

8-16GB is plenty for a dedicated Plex machine If you are running only Plex on that machine, 8-16GB is enough. 64GB is wasted capacity.

The money is better spent elsewhere That $100+ could go toward a better GPU, more storage, or a bigger SSD for your media cache. Those upgrades will actually improve performance.

Extra RAM only helps if you run other heavy apps Unless you plan to run a dozen VMs or a RAM-hungry database alongside Plex, 64GB is just a flex with no function.
