Topic: [4+ EH] Slush Pool (slushpool.com); Overt AsicBoost; World First Mining Pool - page 337. (Read 4382840 times)

I had this problem about 3 times in last few days. 15 minutes ago my both antminers were submitting work and nothing looked different, but for about one hour they were sending results somewhere else, because slush pool was reporting 0 shares. After reconnection everything is ok again... I really hate how many thieves are attracted around bitcoin.

Pool users should check their connections to Slush. I noticed with two miners that I hadn't submitted a share in the last ten minutes. My miners were showing that they were still connected to pool 0, but 46.28.205.80 instead of the normal address. There is talk on Eligius about a malicious player doing a man in the middle attack, it's worth reading up on.

The ones being confirmed are solved but require 100 confirmations before allowing them to be apportioned out as transferable earnings thus unconfirmed. The others are attempting to be solved.

This is a noob question, but it has had me stumped lately because it seems to be happening all the time now. Can anyone comment on long delays for new blocks showing up on the statistics page after the last one is confirmed? The miners show they are working on a block number that is higher than the last bock listed. Is it that blocks aren't listed until found and we only see found blocks being confirmed, not the ones we are searching for?  Thank you! MCTV

No, it just means that for that day average number of d1 shares per block was 3.448276 times more than expected for the day. Greater hashrate will reduce variance (the extent of the bad and good luck) but not get rid of the bad luck itself.

Hopefully it's just a glitch that they fix soon. I find the more hash power I add the lower my reward becomes. Other day seems they updated their system which is now calculated every 5 minutes for the past 60 minutes. I'm hoping this does not mean even though we mine all day and night on one block we're only rewarded for the last 60 minutes of it.

Hi,

maybe a kinda dumb noob question, sorry for that, but i wonder, if all blocks are mined and no new block(s) have been found, what are we actually doing then? I noticed yesterday (friday april 25) during a quite long time all blocks were solved and no new one was found yet. I'm just curious if we're mining of just wasting electricity.

Another quite newbe question about the etimated reward: when I was mining at 800 M/hash the estimate reward was about 0.025 or so. Then I went up to 1 T/hash and the estimate reward was about 0.025. So I upgraded to 1.2 T/hash and the estimate reward was about 0.025. Since yesterday I'm mining at 1.8 T/hash and the estimate reward is still about 0.025. Weird or what?


Thanks for your help,

Michael

i see Pool luck (1 day, 7 days, 30 days):   29%, 108%, 93% , 29 is bad is this a sign? a sign that more GH needed?

    You can save money by using any old USB Hub and old ATX PSU instead of
it's default power supply (even old 300 W PSU will give out at least 10 A which
is more than enough for 7 of any USB ASICs).
   You should open it first and check if any Caps on the ATX PSU are leaking
and replace them or just don't use that PSU.
    You just need to shorten BLACK and GREEN wires on ATX plug with a piece
of metal or copper wiring to give it a start and then solder RED Wire from any
Hard Drive / CD railing to 5 V on the HUB factory power supply jack and BLACK
(Ground) wire next to the red (one is enough) to GROUND on USB jack HUB side.
    From what I've seen all those USB ASICS tend tend to pull more power
than factory declared values and then they get really hot and pull even more.

PS. IF you have a multimer you can check which wire in HUB Stock adapter
is 5V by setting it to 20 V and then putting one pin (any) inside the jack
and the other on metal around jack , set Multimer to 20 V and put the other end of multimer (+ and - , don't matter at this point) at the end of USB Hub PSU Jack wires (ground will show 0 V).5V is inside , ground is metal around iton all models I'seen so for but always check twice before soldering the cables.

3 usb Erupters and 1 U2 Antimer are all on one hub now and I don't see them
crying for power or getting too warm (adding some cooling on them , like a passive cooling used for N/S Bridge on old motherboards with a kitchen rubber or two is also not a bad idea).

Same thing can be done on AT PSU but you don't have to shorten GREEN and BLACK wires as they mostly start by themselves and have a build in switch
Just read 10A or more on +5V , open it and take make sure caps don't look blown) and you're good to go  

Actually I was thinking to get my old HeatGun and some Cryoflux and go back to fixing all those old ATI cards with good MHash/s rate as their main flow is generally too much heat even when you don't overclok them so chips tend
to get too hot and actually desolder slightly from PCI-E card.

They still sell here for a hefty price due to litecoin mining.They will mine Litcoins
and I will mine the Litecoin miners  

P.S. Forgot about shipping cost entirely tnx for the reminder , it would go
on top of import tax which can be anything from 20 to 50 %  so no ebay or
amazon for me

I'll second that price range, got mine for $28 each on EBay with no shipping, have seen them pop up as low was $24 on Amazon.

Yeah I paid $50 each for my first 2 on ebay, but only $17 for my last one. But I'm hoping just to save up enough that i can make another decent order from minersource using bitcoin rather than continuing to throw my cash into mining unfortunately the more I spend, the less I earn on slush's pool.

I'll second that price range, got mine for $28 each on EBay with no shipping, have seen them pop up as low was $24 on Amazon.

Try minersource.net they're $19.99 and they do ship internationally (not sure what the shipping will run you).. They also have the Nano Fury II 5GH/s for 39.99.. Planning on ordering a few of those hopefully soon.

   28 Eur so around 38 $ , they're weren't that easy to find here and
I can't order from ebay because import tax here is  calculated in math
formula that would be harder to crack than any crypto formula  

Just out of curiosity how cheap? I've already purchased 7 of these from ebay and planning on ordering more from minersource, but definitely in the market for the best possible pricing.

I've been mining on slush's pool since January and always experienced this issue. They have yet to calculate my full hashrate 27.5 Gh, it rarely goes up to 23, but never stays there for long. So I'll take a shot in the dark here and assume that the speeds are lowered when the difficulty is raised. Regardless I hope this issue will be fixed before my Black Arrows arrive.

I've actually been running all of these for well over a month. I've just seen the issues in the last 48 hours. Prior to that I was seeing around 12-13 Gh/s.

I had the same problem but then I read that it's calculated at an hourly rate and now it's 10 time faster but important thing to know here is that as long your client (miner program) is accepting the new blocks you are getting the reward even if you don't see it right away.I calculated manually   You can see more info (in fact you can see ALL the info) in your stats.

If you're accepting shares you are getting reward.

P.S. Finally found a cheap 2 GH U2 Antminer     

This. It took several days for the pool to report the correct hashrate (1.6TH) in my case.

From one "newbie" to another, how long have you had the devices connected to, and operating on the pool? It took "Several" hours for my system to register the "software reported" numbers somewhat closely matched the Pool reported. I believe in the past, it may have taken up to 10 "new blocks found (resolved and confirmed) before everything looked right.

I'm running a total of 7 Antminers (mix of U1s and U2s) under BFGMiner. The software reports over 10Gh/s in the 5s decaying stat, no hardware errors, and a very low reject rate. THe pool only shows me at 7.7Gh/s. Can someone give me some possible explanations for the difference?

Thanks!
