can anyone share settings for cgminer and kessak for R9 290x thanks.
Config is real easy. Intensity 12-14 (12 is usually best). Set your fans the way you like them, memory to stock speeds, and your engine clock as high as it'll go (1025-1050 is usually stable on a 290/290x without dicking with voltages, 1100 if you want to over volt).
Don't worry a thing about all the other usual scrypt cgminer settings...no thread concurrency to set, no workspace, etc.
Keccak is all about clock speed. You should see about 450-500 with a 290/290x, and you'll love how much cooler your cards are, and how much less voltage you're pulling from the wall compared to scrypt. Kills me to see Maxcoin drop below .0004, because I loved mining that shit.
