Hello everyone. My 280x are giving me only 2.15 mh/s. My settings are :

{
"pools" : [
   {
      "url" : "stratum+tcp://limi.maxminers.net:5555",
      "user" : "xxxxx.3",
      "pass" : "x"
   }
]
,
"intensity" : "18",
"vector" : "1",
"worksize" : "64",
"kernel" : "bitblock",
"thread-concurrency" : "8192",
"lookup-gap" : "2",
"gpu-threads" : "2",
"gpu-platform" : "0",
"kernel-path" : "/usr/local/bin"
}

Also i would like to add that i have four cards and only 4gb of ram so maybe that is a problem? I see everyone is getting about 2.7 mh/s or 2.8 mh/s Does anyone have any idea what could i do to get that performance?

How many cards did you have?
For more than 4 GPUS use the latest drivers from Windows Update.
If you're using 1-4 GPUS try to install Catalyst 14.7 RC:

And try this settings:

Quote

{
"pools" : [
   {
      "url" : "stratum+tcp://limi.maxminers.net:5555",
      "user" : "xxxxx.3",
      "pass" : "x"
   }
],

"name" : "x15",
"algorithm" : "bitblock",
"intensity" : "20",
"hamsi-expand-big" : "1",
"gpu-threads" : "2",
"worksize": "128",
"temp-cutoff" : "95",
"temp-overheat" : "90",
"thread-concurrency" : "8192",
"shaders" : "2048",
"api-listen" : true,
"api-allow" : "W:127.0.0.1"
}

Don't forget to add this lines in your *.bat

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
sgminer.exe --config "name.conf"

On the end... you can try to overclock your GPU core at 1050-1150MHz (HW must be 0).
