Help with a 3070 only giving 30MH/s

Hi,

I just got my first 3070. It’s a gainward phantom.
Updated my rig to lastest HiveOS, and latest nvidea drivers

If I leave default values on my 3070 I get around 27 MH/s.
Using many different settings I found in the forum I manage to go up to 33 MH/s, but this card is suposed to get me up to 60 MH/s

Right now using CORE -600 MEM 2800 PL 125 I get 33 MH/s which is the ax I’ve gotten out of it.

Here’s info about the card

As said I have tried many configurations with similar results. None going higher than 33 MH/s.
I have tried different ports on the motherboard
I have tried turning off all the other cards and leaving just the 3070
I have tried with different power cables

I have search for this specific card on the internet, and I don’t find anything in particular that’s wrong with the card.

This card is LHR, but if I understand correctly with nvidia 470 driver it shouldn’t be an issue, right?

Anyone has any idea what could be wrong?

For documentation sake. LHR card are not completely unlock at this point Sep 2021, but gminer higher than v2.6 can unlock around 70% of the mining power for ETH and other coins.
