CGMiner crash

[Lethn]

I'm sure I'm doing something really dumb that I'd normally spot but it's been so hot here I'm too tired to think properly, would appreciate it if someone could take a look at my settings, my miner starts up and then just crashes when I try to connect to the 50BTC pool.

color 0A
cgminer  -o pool.50btc.com:8332 -u username -p password --intensity 12

Two things to try:

• Put "http://" in front of the pool URL
• Try pool URL "stratum+tcp://stratum.50btc.com:3333"

Also, change your intensity argument to the shorten version, -I

Thanks, I'll give it all a shot it's cooled down finally now so I can think straight lol

Edit: well it's not crashing now but it's not running like normal either which is strange because I can get it mining fine on litecoin alt. currencies etc.

I switched to GUIMiner and I'm getting the error "ValueError: need more than 1 value to unpack"

aw nuts, I thought I had it for a second but then I got this

This is your GPU returning invalid hashes from it's kernel. This is because new drivers are crap for older cards.

- Uninstall AMD APP SDK

- Uninstall AMD Catalyst Install manager: choose "uninstall all software", make sure you have only a VGA driver after restart.

- Manually remove these files not removed by the installer; any other obvious ATI files with the same file date:
  C:\Windows\System32\amdocl64.dll
  C:\Windows\System32\amdoclcl64.dll
  C:\Windows\System32\OpenCL.dll
  C:\Windows\SysWOW64\amdocl.dll
  C:\Windows\SysWOW64\amdoclcl.dll
  C:\Windows\SysWOW64\OpenCL.dll

- Install just the Catalyst 11.11 driver package (no SDK is needed; the AMD APP runtime is included with driver)

- Mine just a bit slower on your 6870 than a 5830 would.

Better:
- use cgminer
- set phatk worksize to 256 and underclock GPU RAM to 300MHz for best power efficiency and higher hashrate

Thanks, I'll try and see if it works.

I managed to get bitminter client working comfortably now, I just wanted to mine some Bitcoins so I could pay for a new webhost that shouldn't suck
