Bumping the thread, got the same problem with mine. Judging by the time this topic was created and still no firmware i’d better return it, which is a shame, because the mouse itself is lovely.

So, I contacted Razer support and they told me to ask for a return with Amazon. I asked them if this issue was widespread or it was only an issue with some mice. Looks like a firmware update won’t fix it, they haven’t mention it. I think I’m going to send it back to Amazon and buy a new one, if it still occurs, I don’t know what to do. I’m a little bit disappointed because I already put corepad grips on it and I have to rebuy some again.

Hi guys, I’ve got the same issue, I just bought a brand new DeathAdder v3 and I have a bug that :

125hz is 16hz

500hz is 60hz

1000hz is 125hz

2000hz is 250hz

4000hz is 500hz

8000hz is 1000hz

I mean, what’s wrong with this mouse ? I did unplug and replug it and it solves the issue, but when I boot, hz are low.

Any luck? Same problem for me! Upvoting for more visibility!

A new mouse has just been bought, connected to a completely clean Windows OS, polling rate 125Hz, restarting the PC does not help ... How to solve this problem?

I tried to install Synapse v3 - the result is the same, but now if I poke and plug the wire into the USB again - the polling rate is 1000Hz, and if I restart the PC - I see 125Hz again on the desktop and in games .. ...I'm very upset, apparently this is a marriage  ....

exact same issue That Post Creator gave infos on.. it might be a software issue maybe on Synapse?  

Someone changed usb port and solves, you can try it.But it didn’t work for me.

Hey man did u ever find a solution to this issue? having a similar issue

Similar problem here mouse is perfect in every way i am just trying to set up 8k polling rate but with no luck yet btw i use to own the deathadderv3 pro but i replaced it with the lamzu and this wired version with bunge is much better but the only issue is the 8k
