ok , I will post mine, with my 280x Saphire dual-x, as u can see in this picture, its rock solid, 0 HW, and very very stable

As u can see i get 366khas over each GPU, and a Work utility over 90%, I use Bamt 1.5 modified by me, with 13.12 ATI drivers, Sgminer 1.4.1 recompiled by me, with new kernels and modified .bin files, if the comunity asks for it, I could share my distro too, so people can burn it, and get it done in an instant, but i will have to remake it a bit, so i can make it special for GNS xDD, and translate it in english ( I have it in spanish mostly for my friends here in my town )

my config is :

{
"pools" : [
   {
      "url" : "stratum+tcp://gns.pool.mn:3333",
      "user" : "",
      "pass" : ""
   },
   {
      "url" : "stratum+tcp://gns.eu.stratum.coins4everyone.com:3474",
      "user" : "",
      "pass" : ""
   }
]
,
"gpu-fan" : "0-100",
"auto-fan" : true,
"temp-cutoff" : "84",
"intensity" : "13",
"worksize" : "256",
"kernel" : "xfear", ( U HAVE TO CHANGE THIS to   "kernel" : "scrypt",  or delete the line simply, I can share the BIN files that this kernel generates too, if someone wants them )
"lookup-gap" : "2",
"thread-concurrency" : "8192",
"gpu-threads" : "2",
"gpu-engine" : "1020",
"gpu-memclock" : "1500",
"api-listen" : true,
"api-port" : "4028",
"nfactor" : "11",  ( IF u USE VERTMINER DELETE THIS LINE TOO )
"shares" : "0",
"kernel-path" : "/usr/local/bin",
"api-allow" : "W:127.0.0.1"
}


I hope someone is helped with this conf file

put a little more volts on your cards and use older drivers 13.xx not 14.xx

You should try to use cgminer. If it can't help decrease HW error, we will test again with some other configs.

Did you try our config in the first page?
