I have a laptop with a GTX3060 and it was the LHR version. Needless to say Dell did not reveal that little detail when I ordered it.
I did not think a laptop GPU what get caught up in NVidia's anti-miner games.
Mining ethash and getting only 4.3 MH/s I decided to install the 470.5 drivers that does not limit the has rate but it would not pass the compatibility check and therefor not install. So after calling the people at NVidia that came up with this LHR every unflattering name I could think of I took a step back to think this through.
I decided to bypass their installer and go the old school method of updating the drive via Device Manager and it installed with issue.
Fired up Phoenix Miner and with a stock setup I am now getting 32.077 MH/s
So if you run into the same issue just update the driver via Device Manager.
Select the Have Disk and browes to the folder with the drivers and make sure to select "Let me pick...". this will allow up to scroll through the list of card and select your.
I have always been and NVidia fan but after this I am seriously think to going the AMD route in the future.
