I could use some guidance please.

I downloaded the new PM 5.3b to mine ETC again with some of my AMD 470 4gb cards. I have a test rig up with Win10 and 20.4.2 drivers installed. I have two cards that are the same except one is 8Gb and the other 4Gb. The 8gb card works fine of course, however, the 4Gb card only finds invalid shares.

Not sure if my image will show up or not but I tried to embed an image.

Any ideas why the 4Gb card only finds invalid shares? I even dropped the mem clocks on the 4Gb card and added more power to see if that would help and it did not. I am about to install SMOS to see if that helps, but would really like to run Win10 if possible.

Just installed PM with SMOS and it is doing the same thing.

Anyone willing to take a guess?
