lol someone is stealing my hash rate. on two rigs gpu 1 have a same hash rate of 1mh/s
Either is claymore or windows.
I guess they are 4GB GPUs, if so read a few pages back
Yes, you are right. I see, 4gb cards are outdated.
You can try and set your -eres 1 and see if it makes a difference but the issue is that the GPU0 (basically the GPU in the main x16 pci 3.0 slot) loads more of the windows resources into the GDDR. Hence its on the brink of completely maxing out its capacity. Hence why your other GPUs are working.
If you have any GPUs that are >4GB then put those in the main GPU0 slot and each of your GPUs which are 4GB should still mine temporarily. However your time is limited, you can try Windows 7 or Linux and buy you more time.
However eventually you just gotta upgrade to the 8GB models to get around this.
