Mining Ethereum and getting 10% stale shares?! Wth!

[liomojo1]

Any fix for this issue?

[yigga]

had the same problem. I switched to another (smaller) pool and there everything is fine. 100% efficiency.

Which pool did you jump from?

[nitrobg]

Other pools also have the same issue, they just don't report stale shares. It is totally normal for ethereum to have a small number of stale shares - they are being rewarded as well anyway.

It is a problem that the pools need to address.

I was on nanopool, had 2 cards hashing Eth and with about 55 mh I was getting miner down notifications constantly even though they were hashing fine. No shares were being found. I decided to switch from nanopool to ethermine and now I'm finding shares but my 1070 is logging 10% stale shares about 60% of the time....strange the 1060 has not logged any stale shares.

switching pools not that easy unless you have alot of hashpower due to the .05 minimum. I guess when I finally get to the .05, I'll switch and try dwarfpool. On Ethermine my hashrate is 55mh, and my calculated is 45mh, thats 20% loss......not an acceptable amount.

i have change from ethermine to nanopool to check if i can have a better hashrate. i know nanopool just dont show the stales shares but i read somewhere else that they changed the diff so less shares but bigger so maybe less stales. i will see in a couple of days

I switched from nanopool to ethermine. even if I receive approx. 5% of stale shares, I get better payout and number of shares increased 20%, comparing to nanopool.

You get more shares with Ethermine because they use a lower share difficulty. Lower difficulty =  more shares worth less each e.g. 100 shares at diff 4000MH are worth exactly the same percentage of a block as 40 shares at diff 10000MH. Using lower share difficulty for higher hash rates is inefficient because you are getting work and submitting shares more often, increasing the load on the pools stratum which can lead to stale shares.

Based on the fixed 4000MH difficulty Ethermine uses, your miner should be getting 60% more shares on Ethermine to be equal to the amount of shares at a fixed 10000MH diff for Nanopool.

nanopool diff is 5000MH not 10000MH, anyway I see better payout on ethermine.

The same situation I have too. I don't trust statistics which is displayed on the pool. I switched to another pool. All the same. The other figures but the income is the same. Let's hope that this is temporary. In any case, I do not see a better option. After hacking and the introduction of new rules I'm not going back to nicehash.

Nanopool uses a fixed 10000MH difficulty, which means it's 60% higher than what Ethemine uses.

okay, it became 10000MH since 6 of January 2018 according to their twitter, I used to mine when it was 5000MH

so... is better nanopool or ethermine?

The stale shares on Ethermine went up dramatically after the Byzantium fork back in October. I think the fixed share difficulty that Ethermine uses is too low for the 15 second block times since the Byzantium fork, which causes too many stale shares. I switched to Nanopool that uses a higher share difficulty and my estimated hashrate on Nanopool is much closer to my reported hash rate.

Nanopool doesn't report stale shares and it combines both valid and stale into calculated/SMA.

Again over 10% stale shares...
Anyone?

[murgorx]

Having the same problem as you guys! Im getting constantly 7-12-15% stale shares, which annoys me really. Last night when I saw 15% stale shares got fcking tilted and changed to mine qbic. Tell me if you find a solution.

[dennisch123]

Its getting fucking absurd, I'm at 20% stale shares for the past 60 minutes

The problem is the speed/time.

By the time you solve a problem and submit a share to the pool, someone else already solved and submited before you = stale share.
The rate at which Ethermine gets new blocks is ridiculous, so when you submit your share, we are already mining a new block.
