[ANN] profit switching auto-exchanging pool - www.middlecoin.com

[ddd1]

From 5th feb to 17feb I have gotten average 0,0106btc/mhash/24h, is this ok result?

decent.. this is from accepted hashrate rite? not from your CGminer output?

it is calculated from my cgminer WU, my WU is usually about 92% of my real hashrate.

so basicaly if I calculated btc/mhash from the total hashrate instead then it would be 0,0106*0,92= 0,009752btc/mhash.

Guys,

What can i do to decrease the reject rate of my rig? I'm getting too high reject rates

It's probably a network issue on your side - high latency (which could also be from being far away from the mining server) or frequent hiccups (very likely if you download large files without throttling it -- home routers and operating systems do a god-awful job of distributing bandwidth). What're we talking about - 5% stale?

If talking about HW errors, the solution usually is to lower intensity. Many cards won't efficiently mine Scrypt on max intensity.... often have to lower it to I 12 or 13.

Hello fellow spammers,
I have been using this pool since the start of February. At start it was bad - first day I had no payout, second day was better and third was quite rewarding. I put 2 rigs here :
one has 4x280x (upgraded to 5 @15.02.2014) and one has 4 x 290 (will upgrade to 5 soon). I am quite happy with the results (even with those low payments recently) because with almost 0 effort you can mine here decently. Your unexchanged will sooner or later turn into BTC so why all the spam and hate towards the pool manager. The guy is doing quite nicely and all of you haters and complainers are just too damn lazy to do something besides spamming. I removed my first machine from the pool so I can experiment on other currencies and try to do the job myself and I had good and bad days - last 3 days 0.07 BTC perday. So this just shows you that if you wanna profit - stop being lazy and blame it on h2o.


P.S. For those who use 290 - I had a lot of rejects @ start so I changed I from 20 to 18. I use gpu clock 980 memclock 1250 and hash 840 per card under Litecoin BAMT 1.3 with very little rejects.

What is your percentage reject rate? Mine is 1020 and 1250 with hash of 897 cgminer 3.7.2 with 8% rejects.

Having very high reject rates with new rig running 2x r9 290 tri-x runni sgminer and 13.11 beta drivers. Bat file as follows

sgminer -o stratum+tcp://middlecoin.com:3333 -xxxx-p x -I 23 -w 256 --thread-concurrency 32765 --gpu-engine 1020 --gpu-memclock 1500 --gpu-fan 85 --temp-target 88 --temp-overheat 92 --temp-cutoff 98 --gpu-powertune 20

Can't get these cards running with cgminer at all.

Any suggestions?

"-I" is too high. Start with 18/19/20. Check the hahsrate/rejects/WU and settle for the best values (depends also on what server you're hashing).

GPU and memclock might be too high as well. safer settings are 947/1250 or 975/1350 or 987/1425. Let it run a while (day or two), see if anything goes sick/dead/off. Have a good PSU?

I have 4xr9 290 cards running those setting stable and no issues, strange these cards don't like it. Tried intensity lower keep getting display adapter failed message it runs perfectly for 10 mins thn get the error. Psi is good antec 850w.

I am no expert but I would think to run 4xr9 290 you need at least 1200w, preferably 1300w.

Sorry, i am running cgminer on one rig with 4x R9 290 cards and an antec 1300w psu with the following settings

--lookup-gap 2 -I 20 -g 1 -w 512 --thread-concurrency 28456 --gpu-engine 1020 --gpu-memclock 1500 --gpu-fan 85 --temp-target 88 --temp-overheat 92 --temp-cutoff 98 --gpu-powertune 20

on middlecoin currently getting rejects of around 15%

second rig has 2 x R9 290 Tri-x couldnt get it running with cgminer so read a few threads saying sgminer is better for those cards. litecoin mining hardware comparison page recommended settings had intensity of 23 thats why i ran it at that. Currenly running that rig with the following settings:

-I 20 -w 256 --thread-concurrency 32765 --gpu-engine 975 --gpu-memclock 1350 --gpu-fan 85 --temp-target 88 --temp-overheat 92 --temp-cutoff 98 --gpu-powertune 20

on middlecoin i was getting around 40% rejects. I switched both machines over to altcoinplex just to try it out, rejects went to around 3%. With that being said no to confident with that pool, my total hashrate is 5.2mh/s and their stats page was only showing up as 3.3. Payout looks really low as well.

I=20 and rejects of 15% are normal. Go down to 19 or 18. The reason you're getting so many rejects is because the pool is changing coins frequently and you're submitting old data.

When you talks about Sgminer and an intensity of 23, you probably mean XIntensity.

XIntensity=23 is your number of shaders times 23= 2560 x 23= 58880 threads. I=23 is 2^23 times your shaders = 8388608 x 2560 = 21474836480 threads.

Also, don't use I with XIntensity, they don't go together.

Doing a little test comparing Wafflepool with Middlecoin.

System 1: 888 kH running on wafflepool (818.1 WU/m)
System 2: 1465 kH running on Middlecoin (will update WU/m later today)
Dates: from the 9th until today
Location: EU, both are using closest servers and so far basically no downtime (at least nothing that I've noticed on either) on either pool during this period.

Results so far in daily earnings per MH paid to my BTC wallet:

from the 9th until today
Wafflepool: 0,012400744
Middlecoin: 0,012222466 (forgot to take note of unexchanged)

from the 12th until today
Wafflepool: 0,012275473
Middlecoin: 0,011666822 (took note of unexchanged )

My BTC address so you can compare on your own:
http://www.middlecoin.com/reports/156hqodvbN4ugtnYMMc87c71pjRqBzPxub.html
http://wafflepool.com/miner/156hqodvbN4ugtnYMMc87c71pjRqBzPxub#


I will run this test for another week or so, but so far waffle is showing slightly higher earnings than MC does. If anyone spots anything wrong with my calculations please let me know, the data is there for you to check. This increased earning seems to do with me getting about 8.5% rejects on middlecoin + its higher fee, whereas my rejects on wafflepool is 2% and 1% fee. So it does seem that middlecoin seems better in terms of mining coins during the period I mined, but that its higher reject and fee make the overall profitability lower. The overall difference is very low though, and wafflepool is better looking imo ^^. Basically, it seems that profitability is determined by what works for you.

[kylekartan]

Anyone have any experience with Poolwarz.com?

Yes, I've been pointing my desktop (~100kh) to it for a couple weeks now for giggles. I'm not paying the monthly fee, so I don't get auto-switching, I just play with it manually. There is no automatic payout to BTC that I've seen, so I have a bunch of addresses and auto-sell's at Crytpsy. For the small volume I'm producing, it's not too big a deal, but I wouldn't want to bother with all that trading if I had a proper rig pointed at it.

Overall, it's fun to play with, but not really worth the effort, especially when compared to the ease of middlecoin.

[igroock]

The high unexchanged is fairly common. People ask about it every week.

I've been on Middlecoin continuous since last summer, and beta tested them with another address earlier in 2013.  Others pools have popped up on occasion and I've tried most of them.  Only Hashcows came close to matching Middlecoin's rate of payout averaged over a long span of time, but they haven't been the same since their holiday hack.

None of the other pools have Middlecoin's primary strength: H20dyssey's ability to sell coins when no one else can at a price no one can match.  He manually trades like a hedgefund manager instead of just relying on Autotrade. High unexchanged is an artifact of this.

Biggest example was during the Doge craze during the winter holidays.  He jumped on Doge 4 days before any other pool did, then waited to sell until Cryptsy locked up with Doge exchange issues.   Hashcows and direct Doge miners couldn't sell on their favored exchange.  People were clamoring to buy but couldn't.   H20 sold and we made a killing.  That's what your 3.88% or so fee goes to.   Well worth it.  

So don't worry about these high unexchanged values.  I love it when they get high, because at the end of the day, we get a bigger payout than if we just autosold everything like all the other multi pools out there during a market downtrend.

BTW- this isn't even close to the highest unexchanged values we've seen.

I have been on MC for over a month, and while some days are good in terms of pay, others are not, and are FAR bellow what other pools take in.

I find it scary how many of you are sitting here and defending MC like its a religious institution. If you think the last 4 days have been good payouts then you need to look again. And last time I checked these forums are here to specifically state your problems and question the pool operators. People started bitching at me for voicing my concerns and that I mentioned other pools, when I was simply comparing stats based on same days. Bottom line is something is wrong with MC. Its either mining a bad fork in a coin which it didnt mine much in the part, or a server side issue. My 10.3 mhash ran for 24 hours and I got a pitiful 0.026 payout, while my other 11.0 machine took in 0.1139 on Waffle. You are going to tell me that's normal? Sure there are a ton of un-exchanged, but those un-exchanged coins are from 5 days ago, FIVE DAYS! They could have already lost their value. That is the whole point of a profit based pool, to exchange coins as they are being mined. If I wanted to hold on to coins for that long I would mine a specific coin and just hold on to it.
I also question MiddleCoins hash rate being displayed at the bottom. I cant be the only one that switched pools in these last few days because of pitiful payouts, yet hash is almost unchanged.

I am no expert but I would think to run 4xr9 290 you need at least 1200w, preferably 1300w.

Gold standard minimum, go platinum it is worth the extra investment for security and piece of mind.

You could try to use ather bios to lower your watt, but you still need at least 1200W PSU.
https://litecointalk.org/index.php?topic=12830.0 to get better bios for 290, 290x
I am running 840KH at 250W with R9290, stock is 870KH at 300W.
840KH is with i=18, and 2% rejects.

I have upgraded bios on the 4 r9 290 cards just dropped intensity and decrease rejects to approx 3%. Do you know of any bios updates for the r9 290tri-x cards?

I have a antec platinum 1300w psu running the 4 cards. It would be drawing around 1500w at the wall. Is this safe to run long term?

You're barking up the wrong tree with criticizing my posts... I'm not one of the religious fanatics here.  I jump and split my farm to where the profit is.

The only difference is that I'm relating over 7+ months experience to your one month.  The last month and a half have been the worst I've seen at Middlecoin.  But the "Worst" is relative.  The "Worst" at Middlecoin is just below my other test miners in the competing pools.  5 out of those 7+ months, Middlecoin has been about 1 1/2 times more profitable than the next pool on my test list on average.  The reason is that it gets big spikes of payout when H20 makes the big trades that I alluded to and that skews the average up.  He hasn't made a big big trade like that this past month though.

So if I see a long term viable pool that has more profit over time then I'll definitely jump to that... and I have.  I was a big cheerleader for Hashcows before the hack-n-grab.  I'm still rooting for them.  But Atriz and NearMiss have to do something different to get themselves out of their death spiral and they haven't even gotten all the old features back yet by their own admission.
The other pools people have mentioned here are pretty promising on the face of it, but haven't proven themselves over a long timeframe.  Wafflepool for instance only JUST became somewhat more profitable in the last week and half, but that could be tied to market forces.  I'd like to see their numbers after 2 months.  Over a week and a half ago and they were woefully underperforming.

So please don't count me as one of the Fanbois... I'm just relating my experience and I jump where the long term profit is... so YMMV.

Sorry I didnt mean to quote your whole post, my comment got lost about the whole personal broken comment you made. Dont take it the wrong way

What pool have you been using besides MC?

I dabble/test a few others like Hashcows & Wafflepool. I used to 50/50 MC and Hashcows before the hack. I'm going to test trademybit and clevermining at some point and will throw some hashrate over to Scryptguild when it gets to a stable beta stage.
For now though, I have most of my GPU hashrate on MC.

For ASICs and direct BTC mining, I use my own p2pool node with Elizium and BTCGuild for backup.

[mark613]

Seems like the stats have been trickling up at a very slow rate these last 10 hours or so.  Hope we haven't been mining a forked dogecoin.

[igroock]

I believe thats been the issue the last few days. Payouts have been terrible. There was a bad fork with KittehCoin, and now Doge. I switched pools for now.

I agree payouts are horrible and Slooooooooowwwwww I stopped mining Middlecoin and *Surprise* still waiting for payout.
Unless the Dev shows there was some sort of Bug issues this past week i won't be using MC ever again.

Couldn't agree more. Everyone is telling me I am crazy, but its obvious there is some sort of issue. Just 5 days ago MC was working great, after those 5 days payouts slipped to 0.0048 per MH from 0.1140.
Real question is where the hell is H2o?

Switch to a diffrent pool... I'm on clevermining.com, admin is alive, and also on the bitcoin forum
Nice payout, and great graph.

[fcmatt]

I have to admit I am disappointed how this is going. At a certain point in time I will have to cut my losses and when asked tell others to avoid this pool.
Nothing makes much sense with what is going on. I am down about 30-40% of what I should have mined in the last 3 days and I am on track for another terrible day.
Time to change I guess. No feedback except some twits.

[ckoeber]

For the last few days there has been this nonsense called cooperation and understanding on this thread.

But now I am happy to say excellent; the whining has returned!

I knew I could count on this thread!

I would not call it whining myself but eh.. who cares.

All I know is that I just took 5 minutes to switch away from this pool as my 3-4 day experiment failed.
I would estimate a solid 30% loss in payout compared to mining an alt coin or two myself. Prob more.

The point of this pool was to pay a nice fee to the admin to manage it for me and i lost a few hundred dollars.
Perhaps I will come back if I see the graphing on the main page improve to show consistent payouts that are more then
if I just mined dogecoin non stop.

Hello fellow spammers,
I have been using this pool since the start of February. At start it was bad - first day I had no payout, second day was better and third was quite rewarding. I put 2 rigs here :
one has 4x280x (upgraded to 5 @15.02.2014) and one has 4 x 290 (will upgrade to 5 soon). I am quite happy with the results (even with those low payments recently) because with almost 0 effort you can mine here decently. Your unexchanged will sooner or later turn into BTC so why all the spam and hate towards the pool manager. The guy is doing quite nicely and all of you haters and complainers are just too damn lazy to do something besides spamming. I removed my first machine from the pool so I can experiment on other currencies and try to do the job myself and I had good and bad days - last 3 days 0.07 BTC perday. So this just shows you that if you wanna profit - stop being lazy and blame it on h2o.


P.S. For those who use 290 - I had a lot of rejects @ start so I changed I from 20 to 18. I use gpu clock 980 memclock 1250 and hash 840 per card under Litecoin BAMT 1.3 with very little rejects.

What is your percentage reject rate? Mine is 1020 and 1250 with hash of 897 cgminer 3.7.2 with 8% rejects.
