Two rigs with 6 x RX 580 works different

[drale]

Hi, my friend has two rigs with 6 GPUs RX 580 sapphire nitro 8GB.

All two rigs ware working perfectly for months, but last month one rig works 10% weaker and few days ago it is 50% weaker!
Settings are all the same on both rigs.
Take a look screen shots:

the  effected rig has been updated with the recent w10 update. Revert back to the previous driver should get the rig back to normal again.

bro try to uninstall your amd driver then reinstall blockchian driver or adrenaline driver

because  windows update  Is sabotaging your driver

Yes right, like what the masters suggest above. That most likely it happened because the GPU's driver crashes with the latest w10 update.
It's ever happen to me, the solution clean uninstall driver (delete folder AMD also) and revert back update w10.
For the future do not update w10 again.

Do you know if the Nvidia users are also affected by this update? Because I have nvidia card in my computer with which I do mining occasionally, but I have not notice any irregularities when it comes to hash rate.
Maybe it would be better to revert to previous update, and not to wait the moment when this problem starts appearing?

I often had problems like this when I tried to find the perfect overclock settings. Restoring the original settings (mem, core) didn't help really but unistalling/reinstalling drivers always fixed the issue. Use DDU for it.

Seem like everyone agreed, suspected this issue caused by Windows updates. Yeah, that's related to driver issue after Windows update. Few people have the same problem with latest windows update, and here are a few things that can be your solution (has posted above but in a separated post)

- Clean your driver (using DDU) then reinstall the drivers. If it doesn't work,
- Revert your Windows (before the last updated)
- Some people reinstalling their Windows, using old ver of Windows 10

THANK YOU MY FRIENDS!!!

Only I have done is reinstalling AMD drivers and rig works again perfect.
Also I installed Win Updates Disabler v1.4 on both rigs, to prevent similar situations!
