Opencl is what I am using.

Edit: Tried it again and it didn't reboot the computer this time, but it made the screens go black for a few seconds.  I may have to use this on another computer when I network them together because mining drastically harms my frame rates when I am trying to play Rift at the same time as mining.

I found a bug.

I have an ATI card and an nVidia card in the same computer. GUIMiner only looks at the set of devices from platform 0, but with two such cards, the platform also needs to be specified. In my case, the ATI card is under --platform 0, and the nVidia card is --platform 1. So, GUIMiner should support both platform and device selection. Those with only one platform would not worry about this, but those with two or more platforms would not have trouble.

I should also point out that with more than one platform installed, GUIMiner refuses to work at all, so I'm using poclbm on its own.

Please help

Hmm, will do.  I didn't overclock and I'm using the latest drivers, but I'll poke around and see what I can figure out.  Thanks for they help. 

Hi, I'm new to pool mining...Im using GUIMiner with m0mchil, I keep getting "Connection Problems" on one or two of my cards while the others are all running fine, I simply stop and start them and they connect fine...is there anything i can do to mitigate this?

No errors are showing in the console.
No packet loss to deepbit, 130ms ping.

Thanks ahead of time for your help.

zzzz nice catch, didnt notice that, will try that out hopefully fixes things

for cards i have mostly HD 5850s

I was wondering if its possible to mine via proxy through GUIminer.
Im having a big ass ISP that is pulling various crap on me lately... i seriously need help.

thx

Please do.
I think its not rare of having ISP dificulties [blocking certain important ports, etc] proxy would be awesome.

thx a lot

To fully automatic start mining:
1. Put shortcut of GuiMiner to Autostart (Start>all programs>autostart)
2. At Sumonary tab on Guiminer check autostart function
Then it will start everytime u turn on PC.

An option to detect, if GPU becomes idle (ex. due to driver crash) and restart PC would be perfect.
