Armory Crate is ASUS's software for managing RGB lighting on compatible devices

Armory Crate is a free application from ASUS that lets you control LED lights on ASUS motherboards, graphics cards, RAM, and other compatible hardware. If your PC components have RGB lighting built in, Armory Crate is usually the tool you'll use to change colors, brightness, and lighting effects. The software connects to your hardware through your motherboard and lets you adjust everything from a single dashboard on your computer.

The software works only with ASUS components that have RGB connectors or built-in lighting. If your lights are from a different manufacturer, you'll need that company's software instead. Armory Crate is free to download from ASUS's website, and it doesn't require a subscription or account to use the basic lighting controls.

Key Takeaways

  • Download Armory Crate from ASUS's official website and install it on your PC before you can control any RGB lights.
  • Your RGB components must be physically connected to your motherboard via RGB headers or have built-in lighting for Armory Crate to detect them.
  • Once installed, open Armory Crate and navigate to the Lighting section to change colors, brightness, and effects for each device.
  • If Armory Crate doesn't detect your lights, check that cables are seated firmly in the motherboard headers and that your components are powered on.

Download and install Armory Crate on your computer

Go to the ASUS support website and search for "Armory Crate" or navigate directly to the downloads section. Select the version for your operating system — Windows 10 or Windows 11 are the most common. Download the installer file to your computer.

Run the installer and follow the on-screen prompts. The installation is straightforward and takes a few minutes. Once complete, restart your computer. Armory Crate will launch automatically after the restart, or you can open it manually from your Start menu or desktop shortcut.

Connect your RGB components to the motherboard

Before Armory Crate can control your lights, your RGB devices must be physically wired to your motherboard. Most modern ASUS motherboards have RGB headers — small connectors labeled RGB_Header, RGB1, or similar. Check your motherboard manual to locate these headers; they're usually near the front panel connectors.

RGB cables from your components (RAM, fans, coolers, or case lighting) plug into these headers. Each header can control one lighting zone. If you have more RGB devices than headers, you may need an RGB hub or splitter, which also connects to a motherboard header. Make sure all cables are pushed firmly into their connectors — loose connections are the most common reason Armory Crate won't detect lights.

Open Armory Crate and locate the Lighting section

Launch Armory Crate from your Start menu or taskbar. The main window will show several tabs or menu options. Look for a section labeled "Lighting," "RGB," or "Aura" — the exact name depends on your motherboard model and Armory Crate version. Click on it to access the lighting controls.

Armory Crate will scan for connected RGB devices and display them as separate items. You should see your motherboard, RAM, graphics card, fans, or other components listed if they're properly connected and powered. If nothing appears, move to the troubleshooting section below.

Change colors, brightness, and effects for each device

Each RGB device in Armory Crate can be controlled individually. Click on a device to select it, then you'll see options to change the color, brightness, and lighting effect. Most versions let you pick a solid color from a color wheel or palette, adjust brightness with a slider, and choose from preset effects like breathing, pulsing, or rainbow cycling.

Some effects sync across multiple devices — you can set all your RAM and fans to the same color and effect, or keep them independent. Experiment with the settings to find what you like. Changes take effect immediately, so you'll see the lights respond as you adjust the sliders. Once you're happy with your setup, Armory Crate will remember your settings and apply them automatically when your PC starts up.

Troubleshoot if Armory Crate doesn't detect your lights

If Armory Crate opens but shows no RGB devices, start by checking the physical connections. Power off your PC, open the case, and verify that RGB cables are fully seated in the motherboard headers. Look for bent pins or debris in the connectors. Reseat each cable firmly and power the PC back on.

Next, make sure your components are actually powered. Some RGB devices draw power from the motherboard header itself, while others need a separate power connection. Check that any power cables to fans or coolers are connected to the motherboard or power supply. If you've recently updated your BIOS or motherboard drivers, update Armory Crate as well — older versions sometimes don't recognize newer hardware.

If you're still not seeing devices, check the Armory Crate settings menu for an option to rescan or refresh connected devices. Some versions require you to manually trigger a device search. If one specific component still won't show up, it may have a separate control method — some graphics cards and RAM modules have their own RGB software that runs alongside Armory Crate.

Sync Armory Crate with other ASUS RGB software

If you have multiple ASUS products with RGB lighting, you may also have separate software like ROG Aura or GPU Tweak. Armory Crate can often sync with these programs so all your lights respond together. Look in Armory Crate's settings for an option to enable synchronization or unified lighting control.

Some components may still require their own software to function fully. For example, an ASUS graphics card might need GPU Tweak installed to control its lighting independently. Having both programs running is normal and won't cause conflicts — they communicate through your motherboard to coordinate the lights.

Frequently Asked Questions

Why does Armory Crate show my device but the lights won't change?

The device may not be powered or the RGB cable may be loose. Power off your PC, reseat the RGB cable firmly into the motherboard header, and restart. If the lights still don't respond, try a different motherboard RGB header to rule out a faulty connector. Some devices also have a physical power switch or jumper on the component itself — check your hardware manual.

Can I use Armory Crate to control non-ASUS RGB lights?

No. Armory Crate only works with ASUS components. If your lights are from Corsair, Razer, Lian Li, or another brand, you'll need that manufacturer's software instead. Some third-party RGB hubs can work with Armory Crate if they're connected to an ASUS motherboard header, but this varies by product.

Do I need to keep Armory Crate running for my lights to stay on?

No. Once you set your lighting preferences in Armory Crate, the settings are saved to your motherboard. The lights will stay on and display your chosen colors and effects even if you close Armory Crate or restart your PC. Armory Crate only needs to be open if you want to change the settings.

What if my motherboard doesn't have RGB headers?

Older motherboards or budget models may not include RGB headers. In that case, you can't use Armory Crate to control lighting. Your RGB components would need to be controlled by their own software or a standalone RGB controller, if available. Check your motherboard manual to confirm whether RGB headers are present.

Can I control my RGB lights from my phone with Armory Crate?

Standard Armory Crate is PC-only and doesn't have a mobile app. Some newer ASUS motherboards support ROG Aura Creator, which offers limited mobile control through a companion app, but this is separate from Armory Crate. Check your motherboard's feature list to see if remote lighting control is supported.
