Icue making my computer lag and internet speed slow


Recommended Posts

I been having this issue for awhile now and i tried a bunch to fix it and nothing works but shutting down icue.

I notice when icue is running and connected my pc will lag stutter and the lights on my keyboard and headset will stutter and freak out. I also notice its slowing down my internet speed i have gigabit internet and when icue is running im getting speeds of like 50 over 70 highest 120 over 150. I turn off icue and shut it down my speed jumps up to gigabit speeds.

I dont understand how a company can just let this kind of thing stay around for so long. I seen post from years ago saying the same thing and it seems like they never fixed it. Honestly at the point if i cant find a fix on the forums that im just going to get rid of all my corsair stuff fans headsets keyboards and just go with razer.

mobo msi meg ace z490

cpu i7 9700k

gpu msi rtx 2070 super oc

i would try a clean uninstall;


1. Open your computer's Control Panel.

2. Open the Programs and Features options.

3. Select Corsair Utility Engine in the list, and then select Uninstall.

4. Press Window Key + R to open the Run command.

5. Type %appdata% and press Enter.

6. Delete any Corsair folders in the window that pops up.

7. Return to the Run window and type %localappdata%.

8. Delete any Corsair folders in the window that pops up.

9. Open File Explorer and navigate to C:\Program Files (x86)\ for iCUE 3, or C:\Program Files\ for iCUE 4.

10. Delete any Corsair folders in that folder.

11. Type Regedit in the Run window and then click OK.

12. Go to HKEY_CURRENT_USER\Software\ and delete the Corsair folder.

13. Go to HKEY_LOCAL_MACHINE\SOFTWARE\ and delete the Corsair folder.

14. Restart your computer.

15. Download a new installer file for iCUE from Corsair.com and reinstall.
