Hi,
One of my cards sometimes fluctuates the current level shown in GPU-z

The normal current lievel VDDC Current is 93-94 A (Amps).

However the card sometimes falls to 76-77 A for a few seconds and comes back to the level earlier.

Is this normal ? Or it something wrong perhaps with my PSU ?

PS: I recently had one of my burnt cards replaced so don't want the same situation again.

Which PSU are you using and how many cards?

Vcore being a fix value, when the load from the gpu goes down the only thing that can be reduced is amperage. check if gpu load is also lower when the amps go lower.

Will do and update.

UPDATE : GPU load remains stable at 99%. What else could be causing the fluctuation in current ?  Huh

Try switching the PCI power connectors of the card and see if the same card that keeps getting his current drop.

Ok now the VDDC voltage seems to be fluctuating !! Is it the power supply ? Should I continue mining ?

Hey the above update is not correct. The GPU load is fluctuating after kept it running for a day. Someone please help. I don't want to burn/damage my cards.
