Hi All

I bought a second hand GTX 1070 and when running in claymore miner I get this error:

GPU #7 got incorrect share. If you see this warning often, make sure you did not overclock it too much.

I have not overclocked it but on contacting the previous owner he says that he did using MSI Afterburner.

I am currently trying to get Windows 10 working on my mining rig so that I can undo this but I am a bit unsure about how this works.

Am I correct in thinking that overclocking does not actually save anything to the card? If this is the case then any settings the previous owner applied will not be on the card.

Does anyone have any suggestions as to how I can fix this issue?

In a related question I was hoping to apply overclocking settings to the cards in windows and then re-boot into linux and have the cards run using those settings. Is this possible?

Thanks
