was waiting to do the same setup and then read this thread, 4 7990's on zcash pulling 1450w from the wall..mobo gigabyte z97.. thanks! wasnt sure if I had a mobo that would work.
Hi , if you have one more graphic card to put to see if 9 gpus will work? Put on pcie 1234 and 5 if you have time!
Did you overclock it to get this 310sol/s , which driver do you use! Mine work at 1000/1500 and undervolted to 1.13v. Or may be you gave a better cpu?
