Quick Answer

A modded Fallout 4 setup wants 32GB DDR5-6000 RAM, an 8GB-plus VRAM GPU, and a 1TB NVMe SSD as the baseline. A capable SA build around R18,000-R22,000 at Evetech runs a 4K texture and weather overhaul list at 60fps-plus, the practical target for the engine.

RAM, VRAM and Storage Explained for Modded Fallout 4

Fallout 4's engine is sensitive to RAM and storage. 32GB DDR5-6000 keeps script-heavy lists and large settlements stable, where 16GB can stutter once mods stack up. VRAM stores textures; 8GB runs a solid 2K-4K list, while 12GB gives room for full overhauls. Crucially, install on a 1TB NVMe SSD: the Creation Engine streams cells, and a slow drive causes the long hitches Fallout 4 is known for in the Commonwealth. A 1TB NVMe SSD is the single most cost-effective addition here, cutting load stutter that even strong CPUs and GPUs cannot mask.

A Balanced SA Modding Build

Target a Ryzen 5 9600X, 32GB DDR5-6000, an RTX 5060 Ti or RTX 5070 (around R10,000-R17,000), and a 1TB NVMe. That holds 60fps-plus in modded Boston, which is the engine's effective ceiling regardless of GPU. If you build huge settlements, prioritise the CPU and RAM, since settlement object counts hammer the simulation thread more than the graphics card.

FAQ

How much RAM does modded Fallout 4 need?

32GB DDR5-6000 is ideal. 16GB is the floor, but large settlements and script-heavy lists stutter without the extra capacity.

Does Fallout 4 run better on an SSD?

Yes, much better. A 1TB NVMe SSD reduces the cell-streaming hitches Fallout 4 suffers, especially in the dense central Boston area.

What limits modded Fallout 4 performance?

The engine caps useful frame rate near 60fps, and large settlements stress the CPU and RAM more than the GPU. Prioritise those for stability.

TIP

Fallout 4, 32GB DDR5-6000 and a 1TB NVMe from Evetech matter more than raw GPU power. They tame the engine's settlement stutter and cell-streaming hitches.
