Title: Something does not seem right (mining)
Post by: Kohta on August 25, 2011, 01:24:52 PM
I try to keep my loyalty to one mining pool, and so far i have, i'm showing between 1,050 & 1120 Mhash/s - or according to GUIminer 1085 MHash/s total, during my last two 24 hour pools my income has seemed extremely bad.

I have 1x5970, and 2x 6870, with a single 6870 being RMA'ed, so my 5970 & 6870 are giving the 1085, i expect another 280-300 Mhash/s when i get my other 6870 back (totaling aprox. 1300 Mhash/s)

Running around forums i noticed alot of people having 2 or 3 5870's or 5850's which is around or less than my Hash rate and claiming to make 1.0 - 1.5/24 hours, my last two 24 hour payouts were:

24 hour payout #1 = 0.138
26 hour payout #2 = 0.222
and it looks like my next 24 hours is going to be about 0.206

At this rate, i am not even payign for my light bill,i can't run my PC's for free, otherwise i'd go do F@H, if i could get some advice on what's wrong that would be great, Thanks in advanced.

Only 0.2BTC for 24h?
You should really use another pool. Which one are you using?

It's called Bitclockers, the only other place i have an account with is deepbit, but i only tried it for a few hours because i wasn't sure about the options provided in comparison to my rig's they have Pay per share, and Proportionate (sp?) they both seem like the same thing to me, but my rig's hash rate could impact it one way or the other somehow.

Rig#1 - 5.0ghz 2600k / Radeon HD 5970 (Stock)
Rig#2 - 3.7ghz AMD Phenom II 965 / Radeon HD 6870 920/1150
Rig#3 - 3.2ghz 7750 Kuma / Radeon Hd 6870 920/1150 (currently RMA'ed)

But i'm glad you think that outcome is pathetic because it really doesn't seem right to me either.

It could be extreme bad luck, but the stats doesn't say so: http://bitclockers.com/blockhistory
So... I don't know... Try Deepbit(chose proportionate) for a while and maybe come back on Bitclockers later to see if it changed

Ok, thanks for the advice, i'll give it a try, i;m not really biased to one pool or another, and i'm not saying bitclockers is bad, i'm just not understanding the low rate of pay so far, for all i know it could be user error.

I have about 1.7g/h, and have made around 0.8 via btcguild in the last 24h. They've had some bad luck recently, and I would expect normally to get around 0.9 to 1.0 per day at current difficulty. You can calculate approximately what you should get here: http://www.alloscomp.com/bitcoin/calculator.php

The thing is though, the bigger the pool the more consistent the payouts. Atm if you were to mine solo, you might not see anything for months. BTCGuild is pretty big and they're still quite heavily affected by luck.

None of that proves your pool owners are completely honest (or not). I go for the bigger pools for just that reason.

according to that calculator with the difficulty at 185701 and 1085 Mhash/s it would take 82731 days, 2 hours, 36 minutes? so i would never find a coin solo lol.

I guess you have a point, i should pull my head out of the box and thinking about it, i keep thinking these guys setting up these pools are like company's with warranty's and backed by the BBB, i'm in the wrong mindset, the only other thing that scares me is google search is lit up with deepbit and DDoS attacks, on the other hand they have 5000GHash rate, i think i need to do a bit more reading and digging before i ask many more questions, specifically about how luck works.

A good rule of thumb I've found is:

Divide your KH/s (NOT the MH/s) rate by the current difficulty and you will get roughly the amount of BTC you should be making per 24h at best, assuming that:

  • You are running the miners non-stop
  • You mine at one of the big 3 pools (Deepbit, Slush, or BTCGuild) where the variance is small. If you mine at a smaller pool, you might get lucky days and unlucky days.
  • Your pool is not pool-hopper-friendly. Else you may lose a 10-30% of your possible earnings. See the relevant discussion in the Mining category


So with your 1085 MH/s you should be making around 1,085,000/1,805,000~=0.6 BTC per day at best.

Did you try pps I been with thesse 2 pools , abcpool.co and btcpool24.com with pps rate .00002769 per share and 0% fee,
Just average your shares per hours x 24 x .00002769 = btc/day

My 4x6970 >> 1600mhash and I get around .90-.95 a day, my average is .035 - .04 per hour
Abcpool will pay for Invalid shares  and btcpool24 pay 1.95 btw if u find a block, these pps pool might take week too find a block but who care since you on pps mode

Have you checked your stales? Also I would advise bitminter at the moment as they are giving away a 5% bonus for the next 52 blocks

i make almost that much with a single 6950 at btc guild... try that, i like their interface... 6950s are great cards for a great price btw if you're looking to expand

Huh that's a pretty nifty conversion... I've been taking my hashrate in MH/s and using 2^32 hashes/share, 86400 sec/day, and expected <difficulty> shares/block with 50 btc/block... heh.

Thanks for all the information and replies, for some reason i couldn't make more than 0.3 with bitclockers, and i believe it's because it is score based (i could be wrong), this is "supposed" to be awesome to keep pool hopping down, but the pool hopping still happened's there, around 500-1,000,000 shares there are 800+ workers and 500-600 GHash/s, after that point there are maybe 250-300 workers and 200 Ghash/s, and with that small amount of people, 1 mil to 2 mil shares takes 8-12+ hours and this is where everyone in the pool starts to loose money.

To break it down, from 500 - 1 mil shares on bitclockers, i start to avg. aprox 0.1 btc for the entire block (expected payout) at ~1200 MHash/s, once that 1 mil-ish mark has been passed you see workers and Hash rate for them decline, at this point my btc for the round will start to increase again, typically it will then take between 6 and 8 hours to complete a block on average with them even though it looks like they are paying per share, except i believe if they paid per share by assuming each share is worth 0.0xxxxxxx btc then it doesn't explain why your total goes down over time once you stop mining or become disconnected, other than it being score base, but unfortunately those people who are hopping on between 500 and 1 mil shares eat up the majority of the shares for everyone else, so by the time the block is completed, someone like me gains 0.2-0.3 btc, 8 hours is GOOD from what iv'e seen with them, where-as it has taken 24-32 hours before, i have a family to feed, like i stated above i can't run my PC drawing 1000 watts 24/7 and make $2 a day.

Hopefully no-one will think "less" of me for going to another pool just because it's lucrative, just in the last 24 hours iv'e turns about 0.6 btc which is an enormous turn over in comparison for me. I know other people suggested some alternatives and they all sound promising i just am ready to settle down into one mine, as long as the GPU's are paying for there own time running i'm A-OK with that.

But so far i have seen how a pool works either with or against you, in the simplest way you are one or the other in this scenario, you are either pulling your own weight while the big guys are completing the blocks, or you are being a stepping stone for the bigger crunchers to help complete blocks faster for them at the cost of your shares, atleast those are the 2 sides of the fence i have been on and i perfer to pull my own weight.

-So here is another question i have, i wanted to explore and teach myself how to set up a solo miner, well i did get everything all set up but the GUIMiner said the difficulty was "1", assuming that wasn't an error i checked the calculator and ti stated i'd find a block at my current Mhash/s in about an hour with a 95% chance, which i didn't find anything in 3000 shares/~2 hours, I don't really understand how that works, i doubt it's a difficulty of 1.

For now my mining is a bit inconsistent because of the hurricane, it keeps knocking the power out, here's hoping it will clear up soon for many reasons other than BTC mining.

I've used bitclockers, it pays proportional. If your proportion is small you can expect a small payout. I never noticed any funny business there.  I think that you should log exactly how much time you spend mining on various pools. Measurement is the hallmark of science. Measurement is what you need to optimize your payout.  Once properly measured, proper decisions will become apparent.

I think your math is wrong. The current difficulty is 1805701.

https://en.bitcoin.it/wiki/Difficulty (https://en.bitcoin.it/wiki/Difficulty)

Deepbit is at 5,163 GH/s (more or less) and they are find a block on average every 34 minutes. At 1 GH/s it will take 5163 times longer (on average) for you to find a block solo mining, which is about 122 days.

However, a better measurement is shares/day which most miners don't provide. I use arsbitcoin.com (http://arsbitcoin.com), and they have it available on the stats page. At 1GH/s you should be producing 20,000 shares/day at 0.000027690080 per share which is about 0.55BTC/day.
