Cards not cracking at the same speed

[mothix]

wrong, R9 290 has a default target temp of 95C, and no amd gpu has a builtin "emergency shutdown" of 90C.

mothix, your temps are just fine. the problem is your target temp is set to 87, which means powertune will start throttling the clocks back when the gpu hits 87. this is why you are experiencing erratic speeds. you need to push the target temp back up to 95, and set the gpu clock back to 0%.

Thanks! This seems to have resolved the problem!
