poclbm "failed to subscribe"

[bloodlust80]

Hello

I have an ubuntu 12.04 server with an ATI radeon 7770.

I have the AMD drivers installed, and pyopencl installed.

However, when I run poclbm to try and connect to slush's pool, I get

localhost:8332 07/04/2013 19:45:02, Failed to subscribe                         
localhost:8332 07/04/2013 19:45:04, IO errors - 1, tolerance 2

(I am connecting via stratium proxy and my user/pass details are fine).

What am I missing?

its got something to do with loging into the pool check your username make sure its a "." seperating your username and miner name also re check password and stratum.bitcoin.cz:3333

sorted.

Thanks

I'm a mining newbie, connecting to slush's pool via poclbm with GUIMiner.

I have been mining successfully for about four weeks. It is now showing as a connection problem. I have not changed anything, but for a few days before it quit working, my hashrate fell by about a third. Not sure if that's related. Anyway. Here's my error log:

I just fixed a similar problem by switching from the GUIminer defaults for Slush's pool to "other" and manually entering stratum.bitcoin.cz:3333 and now I'm hashing fine. However in your case Taoimean I think you have played with some settings as it is searching for an AMD card whn you have an Nvidia. Also not to insult you but mining on an Nvidia card is like 95% of the time not profitable, and mining on a laptop is asking for an explosion.

[Taoimean]

Switched it to 'other' and put in the info manually as you suggested and it is working fine now, back on its original (though admittedly still poor) hashrate. As for profitability, I'm really in it for curiosity more than profit. I had read that nVIDIA cards were essentially useless, and I can't afford a better rig. I also keep an eye on my laptop temp and don't run the miner 24/7. Thank you for the warnings. I'm definitely still learning.

What are you getting, about 6MH/s? You are using more in electricity than you will ever make and are probably shortening the lfespan of your laptop. Even if you look at the temps, mining is a large strain for shitty laptop gpus.

[Taoimean]

Electricity is included in my rent for the same amount regardless of how much I use, and the laptop in question is an otherwise out-of-commission one that would be gathering dust otherwise. Still, I don't plan on mining long term. My hashrate is actually even worse than that- 3.7 Mhash/s.

Wow, thats 62 whole cents per month, assuming you run it 24/7. Give up and stop wasting the planets resources.
