Dude I can't thank you enough.
I was struggling yesterday to configure my miner cause what's written at the beginning of this thread wasn't helping and I managed to get my rig last night to 4 MHs per GPU on my R9-280x-es but with your compiled miner and your config I'm getting 14MHs+ per GPU
I cannot get this stable at all with my 280x's Could you share your conf? Would really appreciate it. Get dead/sick workers and windows crashes
Run intensity 20, core clock 1050, memclock 775... Nothing else...
Go up in steps of 10 on core clock until you find breaking point...
