For OBS Studio, the store listing gives 4 GB of RAM as a minimum and 8 GB as recommended. Those are software-level requirements, not a guarantee that a computer can stream smoothly. There is no established universal RAM amount for live streaming: the work you do alongside OBS, your encoder, resolution, frame rate, and scene complexity all matter.
What OBS’s RAM figures do—and don’t—tell you
The OBS Studio store listing states 4 GB RAM minimum and 8 GB recommended for its listed Windows and macOS requirements. The listing’s publication date is not shown in the available information, and these figures are not workload-specific recommendations for streaming a game, recording locally, or running complex scenes.
OBS’s official system requirements article, dated August 25, 2021, does not specify a RAM capacity. It cautions: “Having a compatible system does not guarantee that it is capable of streaming or recording using OBS Studio.” In other words, meeting the listed minimum—or even the recommended baseline—does not prove that a particular setup will perform well.
How your streaming workload changes the answer
There is no official RAM-by-workload chart for the combinations below. Use them to identify what to test on your own computer, not as evidence for a specific capacity requirement.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
| What you plan to do | What to consider |
|---|---|
| Run OBS with a simple scene | This is a lighter workload than running a game and a more elaborate production at the same time, but the available guidance does not give a measured RAM requirement for it. |
| Stream while gaming | Consider the game and OBS together. A requirement for OBS alone does not establish what the combined setup needs. |
| Stream and record locally | Local recording adds another task to the streaming workflow. The available guidance does not quantify its additional memory use. |
| Use multiple sources or browser-based overlays | Scene complexity is one factor OBS identifies when discussing system demands, but no source provides a RAM figure for a particular scene. |
OBS says CPU requirements vary with the encoder, resolution, frame rate, and scene complexity. Twitch also notes that x264 encoding is CPU-intensive and that higher resolution and frame rate require more encoding power. Those statements explain why RAM alone cannot predict whether a stream will run well; they do not establish extra RAM amounts.
Don’t confuse system RAM with VRAM
System RAM is the computer’s main memory. VRAM is memory on the graphics card. Twitch’s guidance for 1440p and dual-format streaming includes GPU and other requirements, but does not state a system RAM requirement. A GPU or VRAM requirement should not be treated as a RAM recommendation.
Rank #2
- 5-in-1 USB-C Hub: Experience comprehensive connectivity featuring a Power Delivery input, two USB-A 2.0 ports, a USB-A 3.0 port, and an HDMI port. (Note: The USB-C power delivery input port is only for connecting an external wall charger to power your laptop and cannot power peripheral devices.)
- 90W Pass-Through Charging: Achieve optimal charging with 90W pass-through power to your laptop, supported by a total input of 100W, with the hub reserving 10W for operational efficiency. (Note: Wall charger not included.)
- Quick Data Transfers: Accelerate your productivity with rapid data transfers using a high-speed 5Gbps USB 3.0 port and two 480Mbps USB 2.0 ports.
- 4K HDMI Display: Enhance your visual experience with a hub capable of delivering 4K resolution at 30Hz in both mirror and extend modes.

Note: This device is not compatible with Linux.
- What You Get: Anker USB-C Hub (5-in-1, 4K HDMI), welcome guide, 18-month warranty, and our friendly customer service.
How to decide whether to upgrade
- Check the software baseline. Compare your computer’s installed RAM with the OBS Studio store listing: 4 GB minimum and 8 GB recommended. Treat those figures as the listing’s requirements, not as a promise of smooth performance for your workload.
- Write down what runs during a stream. Include OBS, any game, local recording, scene sources, and browser-based overlays. The more you run together, the less useful an OBS-only baseline is as a prediction.
- Assess the whole setup. OBS’s stated factors include encoder, resolution, frame rate, and scene complexity. Check these alongside RAM rather than assuming that a memory upgrade by itself will resolve performance problems.
- Check upgrade compatibility before buying. Confirm the memory type, form factor, and supported capacity for your computer or motherboard. Desktop DIMMs and laptop SO-DIMMs, as well as different memory generations, are not interchangeable. Without the exact PC or motherboard model, no particular kit can be recommended.
What high-resolution guidance says about RAM
Twitch’s surfaced 1440p guidance names OBS Studio 32.0 or newer, GPU, operating-system, display-resolution, and upstream-bandwidth requirements. Its dual-format guidance lists supported broadcast software, GPU and driver, upstream bandwidth, and track counts. Neither surfaced set of requirements states a system RAM amount, so they cannot settle how much RAM a particular 1440p or dual-format setup needs.
