Hello EverySingleOneOfYous,
I just setup my 6x290 rig mining talkcoin
I took that chance to upgrade AMD Catalyst to 14.6, and ADL SDK to v7
I'm using djm34 sph_sgminer, OS is a Xubuntu 14.4, system has 4GB of DDR3
First tries didn't get me over 25MH, but tweaking it a bit and BooOOom! >75MH !
Here are the interesting settings I'm using to achieve this hashrate :
"intensity" : "17",
"worksize" : "64",
"kernel" : "nist5",
"lookup-gap" : "2",
"shaders" : "2560,2560,2560,2560,2560,2816",
"thread-concurrency" : "8192",
"gpu-threads" : "4",
"gpu-engine" : "1000-1039,1000-1039,945-1039,945-1039,945-1039,938-1039",
"gpu-fan" : "30-60,30-60,35-65,35-65,35-65,40-70",
"gpu-memclock" : "1300,1300,1250,1250,1250,1250",
GPU 0/1: Sapphire TriX 290
GPU 2/3/4: Asus 290 (AMD case)
GPU 5: Asus 290X (AMD case)
tweaking Intensity was the key

Kill-A-Watt is showing 1400W
Now hoping stability will be there, but I don't see any reason why it wouldn't
Thanks again to you all,
Happy CoinTalking !
