It is one card with 2 GB RAM. I edited the .bat file to:

clpts_x86-64 -u username.workername -p password -t 0

but still having the same problem. It keeps repeating:

Connected to server using x.pushthough(xpt) protocol
The login is configured for and unsupported algorithm.
Make sure you miner login details are correct

The command is:

clpts_x86-64 -u username.workername -p password -t 0,1

My card does have 2GB RAM

I have a Radeon HD7770 and am having problems running the miner. The readme file says that "5000 and 6000 HD cards work, but aren't very fast," what about 7000 series?

When I launch the miner, I get the following:

Messages during compilation of program for device 'Capeverde'
LOOP UNROOL: pragma unroll (line162)
repeated 4 more times.

Connected to server using x.pushthough(xpt) protocol
The login is configured for and unsupported algorithm.
Make sure you miner login details are correct

Any ideas or solutions?
