Mining Performance of AMD Radeon Pro Duo

No benchmark looks to be available and i think it's due to the fact that this card looks to be very expensive and quantity is limited. However, the pro duo seems to be a radeon fury x2. So you can ...

GPU works but cannot find a solution

You should try to remove the latest drivers, meaning 16.4.1 as they are known to suck and install the 15.12. I have no idea as to why but if you do, feel free to answer this question

Hashrate is extremely unstable. Why?

The variance in your effective hashrate is caused by the pool calculating your rate based on the number of shares you submit in a given period. If you're lucky you'll submit an above average number ...

How is average network hashrate determined?

While I can't tell you how ethstats calculates the average network hash rate, I can tell you that they almost certainly don't use reported values from nodes. Firstly, it would be difficult for them to ...

Ethminer reporting low hashrate vs benchmark

This happened to me and here's what I did to fix it. I'm on Windows 10 and was using NVIDIA CUDA 7.5. I was benchmarking at 17MH and mining at 5MH. By Downgrading to CUDA 7.0 I starting mining at ...

GDDR5X mining memory clock issue

Is Mining with hashrate 100 KH/s on my computer same as 100 KH/s on cloud mining?

At the moment it looks like 100KH/s would earn about 0.0008ETH a day. You can find a mining calculator here: https://badmofo.github.io/ethereum-mining-calculator/ that will give you an idea of how ...

How calculate mining hash rate from JUST difficulty and change in block creation times?

I think you mean: D = H * ΔT In which case: H = D / ΔT Which gives you: 1,096,303,811,407,388 / 4 => 274,075,952,851,847 Or 274,075.95 GH/s (Or thereabouts. It looks in the right ball park.)

What to do about low hash rate on EthOS with RX 580s?

I had exactly the same issue on my Sapphire RX580 Nitro+ 8GB cards on the latest Ethos. I expected the stock BIOS to achieve 24-25MH/s, but instead got only 18MH/s on the quiet BIOS or 20MH/s on the ...

Lower than expected hashrates with HD7990

I believe that is essentially what your card is. I know for sure it is two gpus on one board, so perhaps the 7970 and r9 280x are essentially the same gpu, so your 7990 is 2 r9 280x. Claymore does not ...

If me and a friend mine on different computer, how can we not process the same hash when mining?

If you and your friends have the same deterministic algorithm (with the same inputs) to find a hash, then yes, 5 computers are as powerful as 1000 or 1. That is why hashing algorithms are designed to ...
