Need Help with CGMiner settings

[dog2bert]

I am running a HD7970 and HD 7950 on Xbuntu but only getting around 360 kh/s

What can I change to help out

Here is my config file:
{
"pools" : [
    {
        "url" : "http://pool.50btc.com:8332",
        "user" : "",
        "pass" : ""
    }
]
,
"intensity" : "19",
"vectors" : "1",
"worksize" : "256",
"kernel" : "poclbm",

I have similar issue for Bitcoin mining with combination of HD7970 and HD7950 is getting only 550mh/s on xubuntu 12.04

I did not write a config file but while Logging I used I9 and auto gpu and auto fan

[dog2bert]

Did anything fix the issue?

[dog2bert]

What settings should I use for a HD7950 ?

[ghcoin]

try
"gpu-threads" : "2",

[ghcoin]

should
"kernel" : "poclbm",
be
"kernel" : "sha256",
?

You have a mix of sha-256 and scrypt settings here.

It look like you are trying to mine a sha-256 coin (BTC,PPC,TRC,FRC...etc). AS for the kernel I normally use "diablo", but try them both to see what works better for your hardware.
Try:

Code:

{
"pools" : [
    {
        "url" : "http://pool.50btc.com:8332",
        "user" : "",
        "pass" : ""
    }
]
,
"intensity" : "5",
"vectors" : "2",
"worksize" : "256",
"kernel" : "poclbm",
"lookup-gap" : "0",
"thread-concurrency" : "0",
"shaders" : "0",
"gpu-engine" : "1030",
"gpu-fan" : "0-85",
"gpu-memclock" : "1500",
"gpu-memdiff" : "0,0",
"gpu-powertune" : "0,0",
"gpu-vddc" : "0.000,0.000",
"temp-cutoff" : "95",
"temp-overheat" : "85",
"temp-target" : "75",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "2",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}

If you want to mine scrypt(LTC,FTC,NVC....and just about every new coin) here is a basic setup. However scrypt requires much more tuning. At least check to make sure the shaders match your cards.

There are a couple of lists you can find doing a search for Litecoin mining hardware that will give you a better idea on how to dial it in.

If thread concurrency is set, it overrides the shaders option. If you use the shaders option (like below) CGminer will try and guess the best concurrency based on the values in shaders. One uses concurrency directly for optimal fine tuning.

Code:

{
"pools" : [
    {
        "url" : "http://pool.50btc.com:8332",
        "user" : "",
        "pass" : ""
    }
]
,
"intensity" : "13",
"vectors" : "2",
"worksize" : "256",
"kernel" : "scrypt",
"lookup-gap" : "2",
"thread-concurrency" : "0",
"shaders" : "2048,1792",
"gpu-engine" : "1030",
"gpu-fan" : "0-85",
"gpu-memclock" : "1500",
"gpu-memdiff" : "0,0",
"gpu-powertune" : "0,0",
"gpu-vddc" : "0.000,0.000",
"temp-cutoff" : "95",
"temp-overheat" : "85",
"temp-target" : "75",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "1",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"temp-hysteresis" : "3",
"shares" : "0",
"scrypt" : true,
"kernel-path" : "/usr/local/bin"
}

Thank you so much for the suggestions.

I will be mining for bitcoins BTC
