Ethereum mining still profitable?

[rednoW]

Hi, with Asus HD7990 + Block EK reach Hashrate in +50 MH/s ?

Yes, downvolt to 1.1v and set 1100/1650 on both gpus. Add 20% to power limit. Check your temps!
All can be done with windows utilities (msi afterburner, sapphire trixx or asus gpu tweak)

Your 7990 is of good quality. It can run 1100 MHz at 1100 mV.

I thought nano and ethermine was erratic at first but then I figured out how the shares work.  Your hash rate is calculated on the amount of shares you submit to the pool and at nano share diff is set to 5 billion.  So it takes longer to submit a share vs. some pools that have a low diff and submit many shares.  Luck plays it part in your earnings.  In a specific hour you could hit more or less shares in that time frame... you could find a bunch of shares and the pool hits a quick block so your reward will be high.  Like wise you could submit very few shares and the pool finds blocks but your reward will be small.

Over time it averages out so don't worry what your hash on the pool says for a specific time frame but pay attention to the average and you should see hash somewhere around your miner stated hash rate.  Generally the shorter the time for the average the more it depends on luck.  Click on the "JSON Data" on nanopool for more averages.

 Hope this helps mate!

Yes i see more averaging. But what i was pointing out from my picture was the time disappearing from the pool (i circled it) for 3 hours even though the miner was on, and then time repeating itself later where i pointed out (circled as well)

What I see in that picture is 15:03 becoming 15:3 etc... It might be time to take off the tin-foil hat...

it can
1100/1650@1.10
1090/1600@1.08
1000/1375@1.03
950/1250@0.98
Difference between first and the last is more then 100W power.
Stock voltages are ugly 1.20v
It is for ETH only. Other algos need other tuning.

What is the hash rate difference between the first and last? The total power in the first and last?

For the Moneor or qubit mining, the GPU voltage should be higher. It depends how the mining use the core and memory.

Mining of ethereum is still more profitable than the mining of bitcoin. But still, it is not anymore profitable like in past.

It is more profitable than in the past. The Ethereum price was very low in the last year. So even the difficulty has risen, you still make more profit.

I'm not talking about that old. I meant to say, like 1 month back, it was more profitable, than right now.

If you figure 20 mh per gpu the ether network has 85'000 gpu cards mining, that is A LOT of hardware.  So you have to wonder how much more can be added to the ether network or when will it become more difficult.

[Juliamit]

not profitable at all

If your electricity price is less than $0.2 per kWh, you will make profit even with the less efficient miners.

Best calculator.

Doesn't matter which calculator you use, they are all wrong, even using the proxy for better profits you're not going to earn that much. The price could go up again which would be nice, but I think the days of quick ROI for mining gear have already passed, the difficulty is pumping.

That could be the reason why we just receive 80 - 90% of the Ethereum from the mining pools as we expect.

"The calculations accounts for average network blocktime, which increases accuracy but lowers predicted profit. Don't be fooled by other optimistic calculators!"

Also try different pools and proxies if possible. Some of them might give you surprising results.

It is better to use the average network blocktime. The block time is usually faster than the target ones.

[fricircled]

I wonder if wolf0 would ever consider a semi-private group buy in an amd kernel or any other dev for that matter, that would give some of us a fighting chance against some of this increase. 

I heard Wolf0 said the Etherminer is already very efficient. So he might not bother improve the efficiency for just a few percentage.

i tried everything, but with my setup i only get not even 1 ethereum with 66 mega, when the calculator is saying 1.2
