Razer Synapse

When I turn on my PC every time and I open razer synapse, the program doesn’t detect my Razer Blackshark V3 unless I unplug and then plug back in the USB dongle. What should I do? 

My issue is very similar to the one in this thread as in that there is no light on the Basilisk V3 but on my keyboard, the blackwidow v4 the rgb works fine. I have attempted to follow the same reinstall instructions but to no avail

The cooling pad does not work after the firmware update. Only the red light blinks, it doesn't check the temperature, and it doesn't work at all. I deleted and reinstalled Synapse 4 and even formatted the PC. What on earth was this update for? Please take quick action.

I can't add any games to Linked Games. The games are visible in the list (under the + button), but nothing happens when I click the "ADD" button. When I find the game (exe file) myself using "Browse", nothing happens either.This feature is essential and if you have multiple profiles, you can't set anything up automatically!Does anyone have the same problem?Can anyone help?Thank youOperating System: Windows 11 Pro 24H2 (build: 26100.3194)Razer Synapse: 4.0.86.2502180127Connected hardware: Huntsman Elite, Naga Pro, Mouse Dock Chroma

If you have problems:BSOD randomly due to kernel level issues. Any browser web pages crashing with SYSTEM_ACCESS_VIOLATION error. Any programs (especially games) may be random crashed without a specific reason.And also:Laptop with intel cpu 13th or 14th gen. Any updates for system / firmware / drivers / programs - not solved issue. System tools dism / sfc / chkdsk and RAM memory scans - not found any problem.Then most likely next actions will help you fix these problems. TL;DR:Install Intel Extreme Tuning Utility (only Windows 10+). Go to "Advanced View", then to "Advanced Tuning". Set "Performance Core" values so that the panel on the right displays the values as in the screenshot for the underlined parameters, and click "Apply".That's all you need to fix it. Don't be afraid to change the values; the new parameter value will be highlighted, letting you know if it's the right one. They won't be applied until you click "Apply." You can also completely undo all changes by returning to "C

So as the title says, these are what I am using. I am setting up a default profile and I realize this mouse only has 1 onboard memory. That being said I have to ask, how do I save a single profile to the onboard memory. I have 3 profiles but I m only using one, but in synapse 4 I see no icon or anything to “save to memory” like I’ve seen in synapse 3.As some back history, I am dual booting Linux and windows. While the keys default to the profile I pick which is default from the factory, all numbers to its corresponding mouse button number. When I use that profile I get 2 results.Windows everything works as it should….1 is button 1, 2 is button 2 and so onLinux I have buttons duplicating numbers, such as button 5 and button 9 on the mouse output as number 3.I realize there is no  support for Linux, I am just trying to set a profile to stay in memory s the default setup, and go to Linux and it should stay as that As a side note I have tried the linux razer apps as well as piper, all of w

I’m recently bought a Huntmans V3 Pro Mini to connect to my mac mini along side a viper v3 pro for when I decide to do some cloud gaming.  The Viper is identified and connected in Synapse (V4) but the huntsman does not seem to want to show as connected, even though I am typing with it right.  I just am unable to use any of the additional functionality ie. set the arrow keys to the right side shift keys or change the color in Chroma.I’m not sure I can do.  I’ve uninstalled and reinstalled Synapse.  Disconnected my keyboard multiple times.  Delete the devices from Synapse and let it get identified and reinstalled but it still wants to show as disconnected.  

Greetings, since I started using Razer Synapse 4, and unrelated to living in Türkiye, I've been experiencing issues with the macro section. Previously, I could set delays like 0.002, but after adding a period (.), it started directly printing 0. This was resolved by changing the decimal point grouping and the decimal symbol to a period (.) or comma (,) in the additional region settings in Windows' region settings. Today, when I tried to create macros again, the same problem occurred, even though it was happening yesterday. This is really frustrating me. I kindly request that the administrators allow me to create delays here like in the Synapse 3 macro system. Otherwise, I'll go crazy. I need these macros for my work, but I can't seem to figure it out. Please help!

Hi everyone,I recently contacted Razer Support regarding an issue with Razer Synapse 4 crashing a few seconds after launch (case handled by Rex from support). I was informed that the team is aware of the problem and currently working on a fix that will be released in an upcoming update.I just wanted to ask if anyone else here is experiencing the same issue, and if there are any updates or temporary workarounds that have helped.Thanks in advance for any info or suggestions!

Hi there,posting this because the usual “clean reinstall / use the Razer cleaner / check services” advice did not fix anything.Issue:Razer Synapse 4 stopped loading correctly on Windows startup. The Razer tray/container starts, but Synapse itself does not fully launch. Opening Razer manually shows that Synapse is not running or only partially initialized.What I already tried: Full uninstall of the Razer package Razer cleaner tool Fresh reinstall Windows Fast Startup disabled Razer Elevation Service set to Automatic for testing Task Scheduler delayed startup None of that fixed the real issue.What the logs show: RazerAppEngine.exe is running. RzEngineMon.exe is running. Razer services are running. Synapse installer log shows “installation complete.” But launching only RazerAppEngine.exe starts the tray/container, not the actual Synapse module. The important finding:Razer’s own launcher log shows Synapse is supposed to be started with:--url-params=apps=synapseWhen I run

Hello,I am using a Razer Seiren V3 Chroma with Synapse version 4.0.63.2605250927.I would like to ask about the RGB lighting behavior of the microphone.When using the Audio Meter effect under "Quick Effects," I can set the source to "Default Recording Device," and the RGB lighting correctly reacts to my voice (microphone input).However, in this mode, I cannot customize the Audio Meter colors.On the other hand, when I use the Audio Meter effect in Chroma Studio, I can customize the colors as desired, but the RGB no longer reacts to microphone input. Instead, it only reacts to system playback audio such as YouTube videos, music, or game sounds.What I would like to achieve is:RGB lighting reacts to my microphone input (my voice) RGB colors can be customized through Chroma StudioIs there currently a way to configure this behavior in Synapse?Additionally, is there any option to make the Audio Meter effect in Chroma Studio use a recording device (microphone input) instead of playback audio?Th

I would like to report a reproducible issue with the Razer Tartarus Pro on Synapse 4. After a cold boot, the Tartarus Pro fails to output default keyboard binds and custom keyboard binds. The device is still detected by Synapse 4, profile switching appears to work, and macros can still work. Keyboard-output binds do not function until the Tartarus Pro is unplugged and reconnected. The issue appears to occur when the previous shutdown was initiated using Windows shutdown.exe with a timeout value greater than zero, for example: shutdown /s /t 60 Microsoft documents that when the shutdown timeout period is greater than 0, the /f parameter is implied. Microsoft also documents /f as forcing running applications to close without warning users. The issue does not appear to occur when using a full shutdown with no timeout, for example: shutdown /s /t 0Windows commands - shutdownThis suggests the issue may be related to Synapse 4 or the Tartarus Pro driver stack not handling Windows forced app

Why Synapse 3 say: ‘Hey, download Synapse 4, we will keep your profiles and macro’s and put them in Synapse 4 for you.’ Then, you open Synapse 4, and there is nothing there -.-...

Hello, after installing Razer Synapse 4 and uninstalling Synapse 3, I encountered an issue where the Chroma profile does not switch to the one set in the Linked Games tab/module when launching a game. Have someone else encountered this problem or is that just me? And do you have solution for it?Thanks! 

someday i installed razer synapse 4. it was perfectly working for over a half year. one day my hedephones razer blackshark v2 didnt connect to the pc(they were working but i couldnt change setting). after some time synapse stoppped opening. i delete all files connected to the razer and set my pc to factory setting(with all my files). i reinstalled synapse and it still doesnt open. i did all things from guide on youtube and it didnt help. my website version of synapse also doesnt see my devices(basilisk v3 and blackshark hyperspeed v2)

Everytime I press the mute button on my headset, my mic volume drops to 0.I’ve seen that a lot of people have this issue and although I tried everything to fix this problem, there is no solution yet so I’m waiting for Razer to correct it…

Hello,I recently purchased a Razer Wolverine V3 Pro, and I am currently unable to use it properly due to a critical issue with Razer Synapse.The controller is detected, but Synapse is stuck on "Loading" / "Syncing Profiles", and no changes are applied to the device at all. This makes core features like remapping, RGB, and stick calibration completely unusable.Key Issues:No settings are saved or applied to the controller RGB lighting does not change Button remapping does not work Stick calibration and deadzone adjustments do nothing Synapse remains stuck syncing indefinitelyMajor Concern:The required Synapse services are missing entirely from the system:Razer Synapse Service (missing) Razer Central Service (missing)Only the following services exist:Razer Elevation Service Razer Game Manager Service 3This indicates that Synapse is not installing or registering its core services correctly.Troubleshooting already completed:I have already performed extensive troubleshooting, including:Multi

Dear Razer Support Team,I am experiencing an issue with my Razer BlackShark V3 Pro headset microphone.Details of the problem:  - When Razer Synapse is uninstalled, the microphone works normally.  - Once Synapse is reinstalled, the microphone stops working completely.  - I have already updated both the headset and dongle firmware to the latest versions.  - The device is recognized by Windows, but the microphone input remains at zero.  Could you please advise on further troubleshooting steps or provide a patch to resolve this issue? I am happy to share logs or perform additional diagnostics if needed.Thank you for your assistance. 

Just bought a new Barracuda Pro headset and a Viper V3 HyperSpeed mouse. Whenever I launch installer for Synapse, I get Server Access Unavailable. Went through all of the troubleshooting steps found online with no luck. Tried to updated BIOS, turn VPN on/off, turn Firewall & Windows defender ON / OFF,  add exceptions etc to firewall, change IPV4/IPV6 settings,  launching installer through earlier versions, trying to install other razer apps first (can’t install anything, same error every time), made sure network drivers and windows is updated, tried wired connection, tried mobile hotspot, WIFI, removed all razer devices and their drivers. Probably forgot to mention a few more since I’ve been at it for hours.Literally nothing seems to make a difference and at this point I’m losing hope which is a shame since there’s so much of the headset features locked behind Synapse and I just bought them today. Any help would be greatly appreciated!

Razer Synapse 4 just randomly crashed on my PC a few days ago, and since then, no matter how many times i reinstall it, it crashes on launch every time, and i think it is because it doesn't have the services that it needs to work. It only ever installs the Razer Elevation Service, and I think it cant install them because it can't get the services package from assets.razer.com, or something. It also just doesn't install the C:\Program Files (x86)\Razer\Razer Services\ folder on my PC. Does anyone having a working synapse 4 installation and has this folder so i can install it through cmd or powershell? Maybe through google drive or something. 

Since the update V4.0.86.2605190956 of Razer Synapse on Windows, the button 9 of the Razer Naga V2 Pro mouse cannot be modified at all. Here’s what button 8 looks like, what is expected: And here is button 9. Notice that the turbo function simply isn’t present: Since turbo was activated prior to this update, it still works. However, this update changed something in the behavior which make the function behave extremely herratically. To fix it I had to tone down the turbo on the button 8 for scrolling up. However, due to this bug I cannot do the same for button 9. A partial fix comes in the way of closing Razer Synapse completely. Even though both of these function uses Razer Synapse, closing it seems to make it behave non-herratically as it did before. However, I change between two profile often so having to re-open Razer Synapse, change profile and close it again is not convenient at all.

I'm experiencing an issue after logging into Razer Synapse. There's an undeletable default app profile that seems permanently saved in the cloud. It syncs back to my local device every time I log in, and it sometimes prevents me from adding new profiles.
