Razer Synapse 2 vs 3: Which Works With Your Device?

Razer Synapse 2 and Synapse 3 are two different driver/software suites for Razer peripherals, and the version that works with your device depends entirely on the hardware you own. Synapse 3 is the newer, unified platform for most Razer products released after 2017, while Synapse 2 remains the only option for many older devices. To find out which one you need, check your product’s support page or the label on the bottom of the device—but this guide explains the differences, compatibility, and how to choose correctly.

Background: Why There Are Two Versions

Razer Synapse is the configuration software that lets you remap buttons, adjust DPI, set lighting effects, and store profiles on the cloud. Synapse 2 launched around 2012 and was designed for the products of that era, such as the DeathAdder 2013, BlackWidow Ultimate 2013, and Naga 2014. Synapse 3 arrived in 2017 with a complete rewrite, introducing a new engine, Chroma lighting integration, and support for newer devices like the Huntsman keyboard and Basilisk mouse.

The two versions are not interchangeable. Synapse 3 cannot detect most pre-2017 devices, and Synapse 2 cannot control newer hardware. Razer maintains both because they never wrote a backward-compatibility layer. If you own a device from the transition period (roughly 2016–2018), you may need to check the product’s specific support page—some devices like the Lancehead were released with Synapse 2 support but later received Synapse 3 updates.

How to Identify Which Version Your Device Needs

The most reliable method is to look up your exact model on Razer’s official support site. Each product page lists the required software version under “Downloads” or “Compatibility.” Alternatively, you can try installing Synapse 3 first; if it doesn’t detect your device, uninstall it and try Synapse 2. Here are some general guidelines:

• Devices released before 2016 (e.g., DeathAdder 2013, BlackWidow Ultimate 2016, Naga Epic) require Synapse 2.
• Devices released after 2018 (e.g., DeathAdder V2, BlackWidow V3, Basilisk Ultimate) require Synapse 3.
• Devices from 2016–2018 may support either, but often only one—check the product page.
• Some legacy devices like the Razer Mamba 2012 have no Synapse 3 support and never will.

If you have a Razer laptop or a device that uses the older “Razer Surround” or “Razer Comms” software, those are separate programs and not part of Synapse.

Key Differences Between Synapse 2 and Synapse 3

Synapse 3 is more than a visual update—it changes how profiles, lighting, and macros work. Here are the main differences:

• Lighting: Synapse 3 uses the new Chroma lighting engine with more effects and per-key customization on supported keyboards, while Synapse 2 has a simpler set of effects.
• Profiles: Synapse 3 stores profiles in the cloud by default, but also allows local storage on the device’s onboard memory (if the device has it). Synapse 2 also has cloud profiles, but the sync mechanism is older and less reliable.
• Macros: Synapse 3 supports more advanced macro recording with conditional logic and delays, while Synapse 2 is more basic.
• Interface: Synapse 3 has a modern, modular UI with a “Modules” section for add-ons like Chroma Studio, while Synapse 2 is a single-window tabbed interface.
• Updates: Synapse 3 receives frequent updates and new features; Synapse 2 is in maintenance mode with only critical fixes.

How to Choose the Right Version

Start by identifying your device model. If you have the original box or the device itself, look for the model number (e.g., RZ01-0254 for DeathAdder Elite). Then go to Razer’s support page and search for that model. The downloads section will show either “Razer Synapse 2” or “Razer Synapse 3” as the required software. If you are unsure, you can also run the Razer Synapse installer—it will scan your system and tell you if it finds a compatible device.

If you have multiple Razer devices, you may need to install both versions. For example, if you have an old Naga Hex (Synapse 2) and a new BlackWidow V3 (Synapse 3), you can have both installed simultaneously. They run as separate services and do not conflict. However, you can only control a device with its matching software—Synapse 3 will not control the Naga Hex.

Common Problems and Solutions

Many users encounter issues when switching between versions or during installation. Here are some typical problems and fixes:

• Synapse 3 doesn’t detect my device: First, ensure the device is plugged directly into a USB port (not a hub). Then go to Device Manager and uninstall the device driver, then replug. If that fails, the device likely isn’t supported—check the product page.
• Synapse 2 won’t install on Windows 10/11: Older Synapse 2 versions may have compatibility issues. Download the latest Synapse 2 installer from Razer’s site (not a third-party). Run it as administrator and disable antivirus temporarily.
• Both versions installed but neither works: Uninstall both, reboot, then install only the one you need. Sometimes leftover files cause conflicts.
• Cloud profiles not syncing: Log out and log back into your Razer account, or check that the correct profile is set as active.

Cost and Alternatives

Both Synapse 2 and Synapse 3 are free to download and use. There is no premium tier. However, you must create a Razer account to use cloud storage and some features. If you prefer not to use Synapse, some devices have limited onboard memory that lets you store one profile without software, but you still need Synapse to configure it initially. Third-party tools like AutoHotkey can remap keys, but they don’t control lighting or DPI settings.

Frequently Asked Questions

Can I use Synapse 3 with a device that only supports Synapse 2?

No. Synapse 3’s driver architecture is completely different, and it won’t recognize devices that were designed for Synapse 2. You must use Synapse 2 for those devices.

Is Synapse 2 still safe to use?

Yes, Synapse 2 is still officially downloadable from Razer’s website and receives occasional security updates. It’s not being actively developed, but it’s not discontinued either.

Can I install both Synapse 2 and Synapse 3 at the same time?

Yes, they can coexist. Install one first, then the other. They use different services and don’t interfere. However, you may see two icons in the system tray.

Why does my device work without Synapse installed?

Most Razer devices have basic plug-and-play functionality. They work as standard HID devices, but you lose custom DPI, lighting effects, and macro buttons.

How do I know if my device has onboard memory?

Check the product specifications on Razer’s site. Devices like the DeathAdder V2 have onboard memory, while older models like the DeathAdder 2013 do not. If it has onboard memory, you can save a profile and use it on another computer without Synapse.

Will Synapse 3 ever support old devices?

Razer has not announced any plans to add support for legacy devices to Synapse 3. The hardware is too different, and it would require significant driver work that Razer has not committed to.
