Title: Noob GPU mining - problem with Slush's pool Post by: IDiggityBC on April 13, 2013, 02:55:24 PM Hey all,
As the title suggests, I'm new to BTC and currently GPU mining until ASICs make it totally worthless. I've got 3 total miners at 2 different locations working in Slush's pool. 2 of them were working fine as of a couple of days ago, but now only my main one is earning shares. [1st IP]: ~250 MH/s, earning shares [2nd IP]: ~30 MH/s, stopped earning shares; ~8 MH/s, never started earning shares. I really wish I could get the miners at the 2nd site earning shares, as I'm losing out on about 10-15% earnings potential. Any advice welcome. Happy mining!

So assuming each PC is assigned as a different worker, are all the settings the same? I know slush pool has been having issues recently. Setup a backup pool with 50btc.com or somethin like that (I would suggest BTC Guild, but they have too many users and would be paying a good amount in fee's) Title: Re: Noob GPU mining - problem with Slush's pool Post by: IDiggityBC on April 13, 2013, 05:06:17 PM Yeah, each machine has its own worker assigned, all pointed at stratum.bitcoin.cz:3333
Just confusing that the 30 MH/s working was working fine until 3 days ago... The two that aren't working probably have the same external IP, as they are part of a massive university network. GUIMiner shows them hashing, just not earning shares. How can it be that they connect to stratum but don't earn?

Unless the university has strict policies, try a different pool Title: Re: Noob GPU mining - problem with Slush's pool Post by: IDiggityBC on April 14, 2013, 01:47:12 AM Very strange.... I got it to work in a command prompt window running poclbm at the command line exactly ONCE today with Slush's pool. Got 3 or 4 shares over several minutes. Have tried both poclbm and Guiminer several times with both Slush's pool and BTC Guild with no success. No shares accrued :(
In either case, the poclbm output reads: 8 MH/s (~0 MH/s) [Rejected: 0/0 (0.00%)] |
