you get credit for every share once the pool finds a block. It has not been wasted. You will be paid once the pool has something to payout. If you want daily small payments your best bet is a pool with lots of 256 hash.

I remember you commenting on it before, but it just won't work for newb pool. This isn't three years ago, miners do not have time to burn - this pool will never find its first block that way. Not only because by now that never materialised first block would need to be shared with about half the internet's worth of pool hoppers, but because the pool will never accumulate big enough hashing power for long enough time if they don't pay something/anything for people to stay. You see the number on poolpicker, you join the pool with crowd of others, dashboard says the pool is hashing at few hundred TH/s, you mine for a  day, next morning you log in to dashboard, no payment issued, nothing earned, handful of miners in pool, 250GH/s average and 200 of it is your test antminer. And it goes on like this for days. With luck like this and payment policy like this WTF would stay? You might as well just mine solo.

Was happily using the pool for months but in the last few weeks I have daily to twice daily occurrence of "job not found" glitches where whatever coin or contract being served by the pool is pointed at something stupid that serves only stales and produces rejections for hours no end.

Re: Problem with AntMiner S3 - Screenshot Available - Need Help

Your blades are not starting up, check Status->System Log and Status-> Kernel Log for errors, but it's most likely not enough power on +12V rail from PSU to start mining. Try connecting both PCI-e cables to only one blade (the one with controller, you'll know quickly which one is which - blade without controller will spin fans full blast after about 10 seconds, whereas the one with controller, providing HTTP access will properly control fan speed and produce web access to the interface )

Keep in mind, that in screenshot below the system is up for only 25 seconds, that's not enough time for blades/chips to start mining.

And just as a side note, using the same pool for all three entries will not offer any load balancing or fail over.

Both of my 1st batch S3's will overclock to 225 and beyond, at least for short time, but both hash slower at 225 and 250 than at 218.5. As in - both 5s and average GH/s figures are lower (barely reaching 400 at 225), whereas they will happily do stable throughput of 440 at 218.5.

The problem with this is that there is no way to know ahead of time what the pool difficulty is and how long it should take to find a share (unless a non-vardiff pool and you are doing the math). You could be resetting the device too soon, or waiting too long.

There is a feature in the works for BFGMiner that does something similar, only it is based directly on the difficulty of the pool and works without additional arguments.

Neat approach, but maybe the issue doesn't really need that much over engineering - even at extreme pool difficulty, if the module/chip/serial (whichever is used to send jobs to the blade) doesn't produce anything in 120 or 180 seconds (or even extreme - 300 seconds), it can be safely assumed as dead, you kind of want it reset, right? Or am I misunderstanding the issue?

I'm still at it with the random no-hashing issue I keep having everyday with my Raspberry Pi & now 8 Gridseed G-blades, up from 6 G-blades, new 6FT USB Cables (down from 10 & 15 footers).  And again, I even replaced the hub with a new Turcom 24 Port USB 2.0 Monster USB HUB W/ac Adapter Power Station.

I have only 2 g-blades running but i seen this often before, the only way i could get the 0 hashing away was after i turned power off on the failing one and power it back up.


minerd written by siklon (cpuminer-gc3355 v1.0e) has by far the best and most reliable built in automatic method of soft resetting stale chips, it's controlled via --gc3355-timeout switch, you just specify number of seconds after no share is submitted before restarting chips, in my experience works every time and it has yet to let me down.

Pool had 20,000 BTC turnover while broken/unmaintained, surely logical step would be to introduce minimal fee (even 0.5%) and hire active developers to maintain it for a share in profits?

If you look on the Middlecoin site at miners results you'll see that anyone who mines regularly is paid regularly and the results are more or less in line other script pools. If someone says that the pool doesn't pay they look silly to anyone who checks it out.
 

I think what the others are pointing out is that if the coins you mined today, at the moment, take several weeks to clear and trade, then you are only paid "regularly" because you bet on the pool long enough to get paid. Yet as nice as it might be (to be paid, regularly, eventually, if you wait long enough)  the payment issued in this fashion is neither truly "regular" nor of any use to anyone who mined with the pool for today's prices.

Miners today hash for earnings and earnings only, any pool is only as good as today's payment and any pool that requires some sort of pledge of loyalty long term before those earnings are released is neither good for the miners wallet nor should it be actively popularized or encouraged to join.

Scenario where middlecoin payments are incidentally delayed due to automatic systems failing and exchange/payments lagging is detrimental to miner and will result in losses.
Scenario where middlecoin payments are consciously delayed due to the system being designed to withhold exchanged payments in order to improve statistics in falling market by creating "lag" and issuing payments at last weeks levels is detrimental to miner and will result in losses.

By far the cheapest option is the old good Dell server PSU N750P series. Modifications to run as stand alone 12V power supply are extremely well documented on the net, it's available everywhere for less than 20 Euros or 15 GBP. Very high and stable output, designed to work 24/7, slim and less bulky than ATX, very low losses (around 7-9W), runs cold and quiet. All you need is two 6 pin cables of modular type, cut one end of each cable, one short insulated wire to bridge pins A1 and B6 on PSU to trigger auto power on, one jumper across A1 and B1, one jumper across B2 and C2 (to stop the fan from spinning full blast in emergency mode). And it just so happens that the +12 and ground output blades perfectly match with 6.3mm female crimp connectors, so adapting 6pin cables couldn't be any easier. I then use short piece of heat shrink tubing around each blade connector to provide snug insulation. 20 minutes of work tops, less than 30 quid in parts.

Our sha hashrate is relatively low. Because of this, we haven't hit a block. Once we hit a block, you'll get paid out on your shares submitted. I am looking at integrating the sha hashrate to a larger pool if the hashrate doesnt start to pick up.

With all due respect, but maybe it's the other way round. Your hashrate is low because you don't pay dailies. Few times when I checked your pool total would go up to few solid PHs then drop back to single antminer throughput at the end of the day - people are led to you by poolpicker numbers, then at the end of the day they check their balance, payments are not appearing, mining is not paid, so they move their rigs away. BTC is a game with very short lifespan, no miner will stay with pool that doesn't pay out daily or at least weekly for work done. Waiting for a lottery block won't break me, I only had one antiminer pointed at the pool as a try out, but if larger entity left fleet of spondoolies hashing away at your ports and didn't get paid 24 hours later, at last nights payout level per GHs - the figure they calculated their income/ROI for that day at, they will never be back, because the only reason they joined the pool was for todays payout figure they found on poolpicker, not something you may eventually pay a month or three years later. It wouldn't be sustainable to do the mining the way you want it done. Just food for thought.

What's the situation with sha-256 payments? I had a test rig pointed at sha-256 pool for few days , it was probably over a month ago, majority of that time pool was mining BTC. My mined shares appeared as "Estimated Coins" on dashboard, that figure is continuously shrinking by the day to smaller and smaller sum, but it has never moved to "SHA-256 Balances" section and never translated to any payout?

Ok I understand. I found some really cheap PSUs ( Tecnoware ) 500W PSU for 25€....what you guys say about that? If they are ok to use, I would use 1 on each miner.

As I wrote, a really cheap 550W PSU in my case was just a waste of time and electricity and single unit ended needing two of them. If you don't want soldering/modding server power supplies you need to invest in proper single rail PSU that either has constant wattage (24/7) figure in specs or is rated at twice the power you need (750W for single S3)

A lot depends on quality and efficiency of the PSU. My S3's arrived today, I only had generic ATX 550W PSUs handy (pci-e wires for server PSUs didn't arrive on time), I hooked it up to generics and a single S3 unit wouldn't power off a 550W PSU. I had to split the load between two 550W PSUs. I then plugged one 550W watt PSU powering only single blade of A3 (one with WRT/config card) into socket with load and voltage reader and a single blade running off some generic chinese power supply is drawing 249W, so far cry from manufacturers figure of 360W per unit, 180W per blade. Obviously losses on 12V rail in this particular PSU must be epic, but fair bet that 750W version of PSU with such terrible design wouldn't be able to power two S3's, you could barely power up one.

Not only that, but according to poolpicker.eu it's average return is in line with other script pools for the last few weeks. Of course, all script pools are doing crap now... But my point is that middlecoin is supposedly doing it with both hands tied behind it's back.

This might have more to do with the way poolpicker calculates or perhaps is even led to arrive at its daily numbers. For example poolpicker for quite some time lists coinking as the top choice in SHA-256 section, however as far as I'm aware coinking isn't actually paying dailies for BTC mining. And without actually issuing daily balance payouts for BTC mining the pool couldn't possibly reach its poolpicker listed daily SHA-256 payout figures. I know this first hand as I run one asic miner for few days to coinking's sha256 pool and my account hasn't been paid for those few days of BTC mining for about a month now, with payment estimate figure in dashboard mysteriously shrinking every day to now a fraction of the original estimate. Several posters here confirmed they had similar experience with that pool, we even posed the question to the owner or one of the owners of coinking on this forum and he chose not to answer any of us.

So either poolpicker base the estimates on numbers released specifically for them by pools, rather than actual mining, or maybe some pools are clever enough to pay little differently to the right account in order to make daily statistics look a little better. Obviously this is purely my speculation.

I agree with middlecoin being in auto pilot mode at the moment, it took forever for my test run balance to move from "Immature Unexchanged" to "Unexchanged" field and nothing moved any further for days. Looking through the stats you can clearly see payments are being issued daily at 2:30 in the night, but it looks like exchanging mechanism (rather than payout) triggers only if address balance is high enough (probably around 0.01 BTC). I always have a dedicated test rig pointed at the pool before committing to a larger scale mining - and I've seen this abandoned/auto pilot mode many times - p2pool.org has few coins with active users but last payouts 4 or 5 weeks ago, couple of my test runs on mega multi pool vanished into black hole, although, to be fair, some coins/pools have such scarce traffic that it might be just some verification issue or unmaintained setup stuck on preforked settings or similar. I just presume most of those pools are some sort of student ventures set up in dorms that remain abandoned until school year starts or something.

Re: GTX 750 ti OR GTX 750

750Ti every time, preferably in "SC" variant. Keep in mind though that even if you mine most profitable coin with it, current ROI per card is around 500 days.
that the number you get, if you don't try to think about what you mine... (using your brain helps a bit at that level...)

edit: if you need 1 year and half to make 120euros... may-be it is better to stop mining...  Grin
you will probably make more with a metal detector on the beach... (or just saving one euro everyday... actually this solution will pay you 3 gtx750ti over your 500days)

Oh, I though the calculation was actually quite optimistic - 750Ti does about 2700kH in X11, 2000kH in X13 or so? At approx 60W @ modest 12 cents per kWh. If he bought the card today, the most profitable coins of the day this very minute are what - HIRO or RZR? Hashing power of single card will allow him to mine anywhere between 15 and 30 cents worth of such coins a day after deducting 17 cents of electricity? Each $169 card paid by 30 cents returns a day.... not very far off.

Are you talking about Gridseed orbs or Gridseed G-Blades?

Mining BTC on Gridseed orb would be pointless, they only do about 8 GH/s at 50W+, so 5 of them would do 40 Gh/s at 250W. You can get better equipment (with higher hash rate and lower wattage) for the money.
