edit: I went ahead and ordered it. Thanks for your help RS. I'll be reading and re-reading your posts and all 106 pages of this thread too.. at some point.
Cheers!
Let me know if you have problems setting it up. There a ton of users here who can help you and some of them may even recommend better pools or maybe their experience will differ from mine. Also, my other posts regarding trying to predict the value of Bitcoin and ASICs are purely subjective/guessing (it was more of a discussion and not supposed to come off as factual - don't pay much attention to those
).
Keep us updated regarding overclocking on that Lightning card.
Hey Russian, you think Btcguild would be better to go with? What is your average btc per day at your hashrate?
I'm in slushs pool right now I think...bitcoin.cz. I am getting about 0.35btc per day at 650 Mh/s.
Ya, I use Slush's too sometimes (when the pool luck rate hits 40-50%, because then it can ramp up to 130-150%+ and from 40-> 100% you get a higher reward rate). But because the opposite happens when Slush's pool hits 130-150%, you lose a lot of efficiency when it drops back down to 40-60% (it's like a roller-coaster). This is why it makes it difficult to measure Slush's average rate. Some days I get 0.35, others barely 0.30.
Last week I again tested the pool efficiency and I keep getting the same results @ 680Mhash/sec in terms of pool rankings. I don't reach 0.35BTC because my system is not always pegged at 99% since I use my PC for other things too (running the internet, watching movies/videos, etc.). That's why your system is probably beating mine if your GPUs are ALWAYS mining and doing nothing else at all.
I decided to do a
2-day average to get a more consistent reading (1150mhz 7970) and over those periods did no gaming or anything GPU intensive (but still browed the internet, watched youtube, etc.).
All 2-day averages are after fees:
BTCGuild = 0.686 (or ~0.343 per day) (after 5% fee)
MTRed = 0.677 (or ~ 0.3386 per day) (I put a manual fee of 0.5% here)
Deepbit = 0.655 (or ~0.3275 per day) (using the Pay-per-Share method)
Slush's Pool = 2-day average isn't consistent enough for this pool (the highest day I got was 0.34336496). But then I got 0.29076656 and 0.30387096.
I am going to Washington next month for 5 days. I am thinking of testing 1 of these pools again for 5 days straight with GPU at 99%. I am leaning towards Slush's Pool since it's so inconsistent and testing it for 5 days would give a better daily average.
If you have been running Slush's all this time, it doesn't hurt to try another pool. 0.35 BTC / day is very good though for 2 stock 6950s if that's your true average (and not a good day at Slush's).
Using
this calculator, 650 MHash rate would give a maximum of 10.65 BTC per month (0.355 based on a 30-day month). You are getting 98.6% efficiency according to that (0.350/0.355), which is incredible. For example, the current 30-day efficiency of Slush's is just 94% using today's data.....and their 7-day average is a disappointing 91%.
