Can anyone help me getting vertminer-0.5.2 working with a R9-280x GPU?
Using the following CFG file:
{
"pools" : [
   {
      "url" : "stratum+tcp://vtc.give-me-coins.com:3337",
      "user" : "usao.GPU1",
      "pass" : "x"
   }
]
,
"intensity" : "8",
"worksize" : "256",
"lookup-gap" : "2",
"gpu-threads" : "1",
"expiry" : "30",
"scan-time" : "5"
}
Getting the following errors:
Error -4: Enqueueing kernel onto command queue.
GPU0 faulre, disabling!

Seems to me, you don't have enough memory (RAM) or the other solution would be :  Increase your Virtual memory as the following: Initial size: 8192; Maximum size: 8192
Hope that will help
Cheers
