Streaming while gaming puts your PC under dual pressure — running the game and encoding video simultaneously. Insufficient RAM causes frame drops, encoding lag, and stream stutters. This guide covers exactly how much memory you need for every streaming scenario.
RAM Requirements for Streaming
Streaming adds memory overhead on top of whatever you are streaming:
| Scenario | RAM Needed | Breakdown |
|---|---|---|
| Stream only (Just Chatting) | 8-12GB | OBS (1GB) + Browser (2-4GB) + Chat (500MB) + OS (4GB) |
| Game + Stream (casual) | 16-20GB | Game (8-12GB) + OBS (1-2GB) + Chat + OS |
| Game + Stream (AAA titles) | 24-28GB | Game (16-20GB) + OBS (1-2GB) + Overlays + OS |
| Game + Stream + Discord + Browser | 28-32GB | Everything above + Discord (1GB) + Browser (2-4GB) |
| Dual PC (streaming PC) | 16GB | Capture card + OBS + Chat + Browser + OS |
Single PC Streaming — The 32GB Standard
For single-PC streaming (the most common setup), 32GB has become the standard:
- Modern AAA games use 14-20GB of RAM while streaming. 16GB total is no longer enough
- OBS Studio with multiple scenes, overlays, and alerts uses 1-2GB
- Stream chat bots and managers add another 500MB-1GB
- Having Chrome open for chat monitoring, stream management: 2-4GB
- 32GB gives comfortable headroom and eliminates dropped frames from memory pressure
- DDR5-5600 or DDR4-3600 is ideal — streaming is more capacity-sensitive than speed-sensitive
OBS Studio Settings That Affect RAM
Optimise OBS to reduce memory usage:
- Software encoding (x264): Uses more CPU but minimal RAM (~200-500MB)
- Hardware encoding (NVENC/AMF): Uses GPU encoder. Slightly less RAM than software
- Canvas resolution: 1080p60 uses less memory than 4K downscaled to 1080p
- Source count: Each scene source (webcam, game capture, browser source) adds memory
- Browser sources: Each browser source is essentially a Chrome tab (100-300MB each)
- Tip: Close unused scenes and disable sources when not in use to free memory

Frequently Asked Questions
Can I stream with 16GB of RAM?
For less demanding games (Valorant, League of Legends, Minecraft), 16GB works. For modern AAA titles while streaming with OBS and Discord running, you will experience memory pressure and potential frame drops. 32GB is strongly recommended.
Does RAM speed affect stream quality?
Minimally. Stream quality is determined by encoding settings (bitrate, resolution, encoder) and CPU/GPU performance, not RAM speed. 32GB at moderate speed beats 16GB at fast speed for streaming every time.
Dual PC or single PC for streaming?
Single PC with 32GB+ RAM and a modern GPU (with NVENC) is sufficient for most streamers. Dual PC setups are only needed for competitive gaming where you want zero encoding overhead on the gaming PC, or for very complex stream productions.
Does streaming use more RAM than recording?
Slightly. Streaming adds network buffer memory and often includes additional overlays, chat sources, and alerts. Recording typically uses less memory but more storage I/O. The difference is small — 1-2GB at most.
