You should watch powermeter and try to lower powerstage or undervolting and if it takes less wattage and its stable then ok.
If not then try to rise powerstage first.
Anyway this works as powestage+undervolt so if you have 900mv at powerstage 7 and second case on powerstage 3, then this 3 will take less wattage.
I dont know exactly what happening, i just know from experience that it behaves like that
Each GPU has own tolerance for undervolting.
Even 6 indentical GPUs from the same part are totally different. Once could undervolt to 900 while other to 850 remaining stable.
Every GPU is very separate case Also risers are important.
Bad risers i think can result in less stable voltage and can cause problems.
In this word there is milion cases that something will go wrong
What i need to do? Thx
I need reebot rig to get new update?
I want to take a look on your rig.
Can you forward ssh port to your mining rig ang give it to me VIA EMAIN (not here !)
Or prepare team viewer to ay windows that is in he same network as your rig ?
Also send me rig name and email of this rig.
I have very little cases that this update fixed maaany cases but also caused new problems that didnt existed before.
Also try rebooting our rig and see if that will fix your problem ! (it might).
If not then write to me to email.
