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

i have this VGA
VGA Sapphire Ati AMD Radeon HD 7770 Core 1000MHz Memory GDDR5 4500MHz 1GB DVI HDMI DP

and even if it works slower than others, i get 460-470 c/m with algorithm 1

with clock GPU at 1180 MHz
mem clock 1300 MHZ
power control 10%

i may say the new miner has improved 20-30 c/m but i'm not so sure

i created a bat with a code like this
<your path to the file>\clpts_x86-64.exe -o ypool.net -u user -p passw -t 0 -a 1
pause

i hope someone can find it useful
