Can't run miner on 1066, see error message. Can't run more than 4 gpu to work....
Tested new t-rex - it works fine with 12 gpu rig and does more hashes.
what kind of error message are you getting ?
will get a 1066 next week... in anycase for now the 1066 is faster on t-rex
4 gpu's is a little strange, you should get 6 without any problem, after you just need to run 2 instances...
