Ok so I have a few changes that I've made to the AMD miner.
I made some changes that should make it a little more stable. I can run an R9 280x all day if the intensity settings are low, around 16 and 1 gpu thread of course.
I also fixed up the config a lot. The "devices" setting is no longer required, unless you need to disable a card or cards. Then you will need to list specific devices that should run in that section.
You no longer need a setting for every card. 1 setting works for all cards now.
You can also have say 2 settings for one section and 1 for another and everything works
For Example
"gpu-engine" : "1080",
"gpu-memclock" : "1250,1500",
"gpu-shaders" : "1280,2048",
"gpu-threads" : "1",
works as it should.
You also no longer need the config file if you don't wish to use it. You can put the settings in the .bat file.
For Example:
setx GPU_FORCE_64BIT_PTR 1
SKMiner.exe --connections 127.0.0.1:9325 user x password x --algorithm sk1024_djm
This is all you need now to start the miner. You SHOULD put other settings in though. Otherwise your performance will be low
A list of all of the optional settings are here:

https://www.dropbox.com/s/h2lcngoudtbuv5w/SKMiner.7z?dl=0Great update ! I will test today with 280x !
Edit: Tested with MSI Amd R9 280x 3GB Twin Frozr. Well, I found 1 block
My first block with AMD ( I will send my block reward to BitSlapper . He is good and helpfull , so he deserve it
Not much but that is all I earn with AMD ). Hashrate is varies. From 25Mhs-35Mhs /GPU. Everythink was good in first 3 hours and after that hashrate drop from 35Mhs to 0Mhs ( zero
) and after that jump back , but just to 6-8Mhs . I also tested with AMD Sapphire 270x Dual-X 2GB, with 4 GPU in rig. Total hashrate was ~55Mhs ( that is not so bad ). Unfortunately no blocks was found! After about 2hour of mining , the miner crash and in the background the miner found xxx blocks and every block was rejected by network. The total power consumption for 4 x 270x was from 450w to 550w, and I think that 550w is too much
and mining CSD with AMD is not profitable at the moment. Maybe if someone make some optimization for amd miner or if price jump ....
So, that was my little review. I just share my experience and I hope I helped to someone
Here is my config file for Amd Msi 280x.
