Thank you. I am using the latest 1.11 firmware and the difficulty is set to 8192, so the latest improvements on the Titan side did not help.
I use Vardiff and it seems to work just fine with 1.11. 1.10 made my die randomly get sick forcing me to have to restart the system to get them working again. But things have been running nice with 1.11. I just hope we get scrypt-n or any of the x11,x13 ect ect to help beef up profits. $27 a day kind of sucks.
