Razer Synapse 4

Now can switch ANC on/off or ambient, but cannot adjust ANC level in Synapse 4 version 4.0.86.2601160905 and beta version 4.0.86.2511170410.Synapse 3 and Audio app are correctly. Since 02-Nov-2024, I reported this issue to Razer Support staff.By the way, last month (10-Dec-2025) Razer Support staff replied me that they tried to fixed.What are Razer doing?

Linked Games and Auto Profile Switch no longer works after an Synapse Update (Jan 2026), profile switch doesn't affect the apps i'm using. i did a clean install to the software, the linked games now takes forever to scan games and i can't even add programs to it.

Hi everyone,My device: Razer Blade 18 (2024) – Intel i9-14900HX / RTX 4080 / Windows 11 Home I’m having an issue where Razer Synapse doesn’t start automatically with Windows, or if it does, it launches very late after the system boots. Until Synapse finally loads, my keyboard shows random lighting effects instead of my saved Chroma profile. Here’s what I’ve already tried (without success): Enabled “Start Razer Synapse on system startup” in the settings. Checked Task Manager → Startup tab (Synapse is enabled). Made a custom Task Scheduler entry to start Synapse at login (with and without delay). Set Synapse to run as administrator. Verified that Razer Synapse Service and Razer Central Service are set to “Automatic” and running. Reinstalled Synapse completely (including deleting leftover Razer folders from AppData and Program Files). Despite all this, Sy

The audio equalizare in Razer synapse 4 is not doing anything to my sound, cant modify anything, the problem started 3-4 days ago. 

The problemAfter the recent Razer Synapse 4 update, somewhere around the end of April - the beginning of May, my laptop settings tab became completely blank.Exactly the same blank tab as in the image in the topic at the link:https://insider.razer.com/razer-synapse-4-55/kraken-v3-pro-tab-is-blank-70072?postid=236934#post236934Only in my case, instead of "kraken v3 pro" it was my laptop "blade 16".The solutionI managed to fix the problem this way:Delete the "Razer" folder in the directory - "C:\Users\%username%\AppData\Local\"; Open "System Settings -> Apps -> Installed apps -> Razer Synapse (three dots, click on modify)". Click "Repair" in the app that opens.The same actions can be seen in the following videos:https://youtu

Synapse 4 is garbage it doesn't work half the time and the other half it keeps crashing, i have never used such a buggy software in my life, its literally reseting all my profiles to default even if i re-import them or create new ones, if i switch profiles for a differnet game its keeps jumping back and forth from 1 to the other, why this is even available yet is beyond me, cant use Synaps 3 installer "Server access unavailable" im using the Razer Tartarus V2 and its completely un-usable with Synapse 4, why could they not allow us to use Synapse 3 locally i dont understand, those that still have synapse 3 can use it locally 

I’ve seen some others have had some problems with installing Synapse 4, but the fixes either I can’t implement because they’re too technical (using PowerShell) or they don’t work for me (closing any Razer processes in Task Manager).Does anyone have any recommendations for a fix that works and isn’t technical?

Hi, I’ve been trying to recreate Sequence Macro like functionality in Razer Synapse. But for some reason it doesn’t really work well. Any ideas what’s the best way to create a macro like this:  

Synapse 4 – Tartarus Pro 8-Way Input Issue (Still Unresolved)I’ve been dealing with an issue in Synapse 4 affecting the Tartarus Pro for nearly a year now.Functionality that worked reliably in Synapse 3 — especially 8-way directional input (diagonal movement) and simultaneous key combinations — is no longer usable in Synapse 4.Since Synapse 3 has been discontinued, there is currently no fallback option.The issue has been documented through multiple support cases (logs, video evidence, cross-system testing) and has also been reported by other users in the community.Most recently, Razer Support stated that it cannot currently be confirmed whether this behavior is a known issue or an intentional change — nor if or when the original functionality might be restored.After nearly a year, this lack of clarity is difficult to understand.Is anyone else experiencing the same behavior?Any feedback or confirmation would be appreciated.

In Synapse 4, Ultra-Low Latency mode is currently not usable. In the text description for it it says “… as low as ~10ms.When disabled, enjoy gaming grade latency ...” when in fact it should be “… as low as ~10ms. When disabled, enjoy gaming grade latency ...”See screenshot attached.  The forgotten space here makes my BlackShark V3 headset unusable because the absence of the space prevents me from enjoying gaming grade latency. In fact, I haven’t been able to enjoy anything at all after identifying this.ProductSynapse 4Software Version4.0.86.2512101100 REPRODUCTION STEPSConnect any Razer headset product that is compatible with Ultra-lo

I’ve been dealing with a Razer Synapse 4 issue affecting the Tartarus Pro for over a year now.Functionality that worked reliably in Synapse 3 — especially 8-way directional input (diagonal movement) and simultaneous key combinations — is no longer usable in Synapse 4.This is not a minor issue. It represents a clear functional regression.The currently suggested workaround (switching to 4-way input) is not a viable solution, as it significantly limits the usability of the device to the point where it is no longer usable for its intended purpose.At the same time, there is no option to return to Synapse 3, as it has been discontinued.This issue has not only been observed by me, but has also been reported multiple times across the community.At this stage, the question is no longer whether the issue exists — but:Is this a known, unresolved problem —or a deliberate change in functionality within Synapse 4?Given the repeated comm

After updating to Razer Synapse 4, my internet connection started dropping for ~30 seconds approximately once per hour. Other devices on the same router (Wi-Fi) worked fine during the drops, confirming the issue is on the PC side.After extensive diagnostics using Windows event logs, I identified the root cause:The following Razer services spam the Windows network stack with hundreds of "hostname changed" events every minute, which eventually causes the connection to drop:- Razer Chroma SDK Server- Razer Chroma SDK Service- Razer Chroma Stream Server- Razer Game Manager Service 3EVIDENCE:With Razer services running (April 23, 2026):Windows event log Microsoft-Windows-NetworkProfile/Operational showed dozens of Event ID 4004 firing every single minute — hundreds per hour, all with "hostname changed: true".With Razer services stopped (April 26-27, 2026):Only ~40 events over two full days, all corresponding to normal

When i try to upload on workshop Chroma effects it dosent upload it works on profile  and macro but not uploads i dont know if its on my side or if its the s4’s problemDid razer stop doing razer chroma effects fixes?I try to find more Chroma effects profiles but its none. Does none buy v4 (Yes i know the switch problem but still)Edit: Tried even with a brand new chroma profile dident work still. Restarted the program also i did.

I’ve already sent this to support but I thought I’ll put this here too.This is an issue I have only on Synapse4.Basically, when ever I cycle keymap(I use 1 as main and 2 for some obscure shortcuts) and use it, Synapse can randomly overwrite the 2nd keymap with the mapping of 1st’s.Here’s a video of me reproducing this issue by spamming keys while cycling, but this has happened multiple times when I’m using Tautarus normally and I don’t spam keys.My temporary solution for this is to dupe the preset so I can switch to it when it happens, delete the original and dupe the dupe for next time...

For a while now Razer Synapse 4 was working great and I had no issues with it but today I opened it and it started to crash over and over a few seconds after opening - at one point it looked like it was going to try to install an update but then it said installation failed and crashed. I tried restarting my laptop and also uninstalling synapse and going to the website to download the latest version of the installer and reinstalling it but this also failed. I am running on a razer blade 18 (2024) with rtx4090 and intel core i9 14900hx on windows 11 latest udate

Hello,I would like to report what appears to be a regression in Razer Synapse 4 regarding macro execution speed, compared to Synapse 3.I am using onboard memory profiles with macros created previously in Synapse 3.When Synapse 4 is completely closed, the macros execute instantly with no noticeable delay, exactly as configured (0 ms delay). However, as soon as Synapse 4 is running, a significant delay appears between macro actions - even when the macro itself is set to 0 ms delay.I have prepared two videos that clearly demonstrate this difference in macro execution speed:• Synapse 3 (fast / no delay): https://youtu.be/NsiYelsQUrk• Synapse 4 (noticeable delay):

I’ve got Asus Vivobook laptop, Windows 11 and Synapse 4 installed.Almost everything was just fine until one of the Windows updates.Sound became crackling, distorted with unstable loudness levels.I’ve tried everything, have texted to support: they just said that my earphones were faulty so I got to return them on warranty… I did it, got a new pair and..The issue is still there.Whenever I turn off “Turn on audio enhanements” in Windows settings the problem dissapears along with better sound, eq and stuff. So it’s not an option.So I tried the following:removed everything with razer tool installed synapse 3 instead of synapse 4Everything WORKS JUST FINE.Installed Synapse 4Issue came back.Also I’ve reinstalled every sound and chipset driver in System, manually clean registry and still no results.Seems like Razer Software can’t work properly with Windows up

Sound quality on my Razer Kraken headset has become completely terrible. I’ve tried uninstalling Synapse 4, turning off all effects in the control panel, etc. I’m about ready to throw away this headset and buy a new one from a different company. Is there a cleanup tool that will delete everything and then I can try again before I throw this in the trash? This is so disappointing considering how expensive this headset was.

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

I want my CTRL key to also send U key presses, but I want it to keep it's original behavior. My Corsair keyboard has an option called "retain original input" which makes it exactly do what I want.I tried to setup a macro on my CTRL key in razer synapse but the issue is it will send CTRL and U but then I cannot "hold" CTRL (to crouch in-game for example), it blocks the original behavior completely.Is this not possible in synapse ?

I'm using a Razer Blade 18 2025 laptop. How do I set Razer Synapse 4 to not overwrite the icm color profile I added in Windows 11? I set the color profile via color management in Windows 11, save it as the default profile. After restarting, whenever Synapse 4 starts, it overwrites my profile with the default profile in Synapse 4. It worked fine for me on the previous installation, but I don't know why it's not working for me now? I noticed that I previously had a custom color profile filled in directly in Synapse 4, but now there is an empty field, see the picture. I'm using a graphics card in optimus mode. Can you please help me? Thank you! 

I ran into an issue with Razer Synapse 4 not showing wireless battery percentage for 2 different wireless models. Both are listed as officially supported and backwards compatible with Synapse 3 and both had the same exact issue with no battery percentage displaying. I uninstalled Synapse 4 and reinstalled Synapse 3. BAM! I can now see all wireless mouse battery percentages. I attempted to troubleshoot with support but it took way too long to get valuable responses and I’m not interested in downloading a software log capture tool. Will check out Synapse 4 at a later date perhaps.I thought I’d post this for anyone who has a similar problem as all of the threads I’ve seen are requesting PM’s and don’t show a resolution status or troubleshooting steps.
