Best setup I could find for a 280x results in the following:

here's the .conf for cgminer:

{
"pools" : [
   {
      "poolname" : "",
      "url" : "",
      "user" : "",
      "pass" : ""
   }
]
,

"intensity" : "10",
"vectors" : "1",
"worksize" : "256",
"kernel" : "keccak",
"keccak" : true,

"gpu-threads" : "1",

"gpu-memclock" : "1200",

"failover-switch-delay" : "60",
"failover-only" : true,
"no-pool-disable" : true,
"no-submit-stale" : true,

"log" : "5",
"log-dateformat" : "0",

"queue" : "0",
"scan-time" : "1",
"expiry" : "10",
"hotplug" : "0",
"shares" : "0"
}

cgminer will not lower the vddc settings by itself. I do that externally using ASUS GPU Tweak. I own an ASUS R9 280x-dc2t.

Hope this helps. Good luck!

thanks!Your conf gave me 30 mh/s more per card!
