Title: low hash rate, mining pool variance/methods Post by: iNs4nePT on January 31, 2012, 11:29:36 AM I've been mining away at a very slow hash rate: ~220Mh/s; currently doing it mostly for the fun, by my calculations it mostly just covers electricity costs. Also, my rig has been on 16/24h on weekdays plus 24/24h. After trying a few pools, i do like EMC a lot (nice features), however i wonder if with this low hash rate, a pool with much higher speeds would be more appropriate, even with some fees (less variance) Also, i am guessing that DGM is probably not the best for 16/24h operation? Suggestions welcome Title: Re: low hash rate, mining pool variance/methods Post by: jake262144 on January 31, 2012, 04:53:52 PM Why do you assume that a bigger pool will be better for you? You'll make a tiny percentage of that pool's hash power and an equally tiny reward per block.
In the long run, variance should not impact your revenue at all. Pool fees will always impact your revenue directly. Mining at 220MHash/s your card won't even generate 1.1 BTC per week. That's just over 4 BTC per month. You mustn't expect higher rewards unless difficulty drops significantly. Make sure those electricity cost calculations are ok.

I Have 290-310 Mhash and i get about 1 Bitcoin every 4 days Title: Re: low hash rate, mining pool variance/methods Post by: ram1 on February 01, 2012, 03:57:39 AM My computer is used for many things besides BTC mining and the computer is powered on 24x7 whether mining or not, so I don't allocate 100% of the electricity usage of the computer to bitcoin generation. It is harder to show a profit on a dedicated rig.
I've tried a number of different pools and I don't think it makes too much difference which a small miner uses. Recently I've been experimenting with p2pool. I don't seem to be making quite as much, but I like the concept.

Not a good guess, sorry. DGM is fine. Sure there will be variance, but your choices are lose a bit then gain a bit because of pool luck variance, or be guaranteed a 7 - 10% loss under PPS. Unless you want to try one of the 115% PPS pools. Title: Re: low hash rate, mining pool variance/methods Post by: iNs4nePT on February 01, 2012, 10:14:30 AM Thanks everyone for the comments.

Again, this is not a 100% dedicated rig and the objective is not purely making a profit, but rather pay the bills, gather some coins and *maybe* justify getting a new card sometime. Thanks again Title: Re: low hash rate, mining pool variance/methods Post by: organofcorti on February 01, 2012, 10:30:26 AM Doesn't BTC Guild use a 5% rate? Anyway, as i simply fail to don understand how anything above 100% could be right... i won't use those. Regarding 115% PPS pools, I think both Clipse and Goat are trustworthy individuals. Clipse has been around as long as I've been here and he's never done anything dodgy. But they're new pools so there'll be down time as they get up and running. If you can put up with that (using auto failback to another pool when they're down) then go for the 15% extra. Especially useful given there's bugger all proportional pools to hop anymore.

Thanks again It comes down to your nerve. Assuming an honest pool op, mining at any pool will give you the same rewards in time, minus fees. But if you can't stand the times a non PPS pool is having bad luck, go for PPS. Extras like EMC has should play a large part in your decision making as well. The only pools I wouldn't suggest you mine at *MPPS pools and prop pools (unless you know how to pool hop) for reasons I wont get into here. |
