We just received ours ... 42m/h atm @ 370w ... mainly due to the 16.5.3 driver ...

The way of deriving the information can be found here. So via the console, function getNetworkStats( sampleSize //!< [in] Larger n give more accurate numbers but with longer latency. ) { blockNum = eth.blockNumber; // Save this value to atomically get a block number. blockTime = (eth.getBlock(blockNum).timestamp - eth.getBlock(...

it does seem the above mentioned lists are no longer available. so try this one, its up to date and recent. GPU hash comparisons

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 imagine that, as fury x looks to be around 30MH/s, this card would be 60MH/s. However for the same hashrate you can use 3 radeon r9 290 with some oc and it will ...

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

Here is a Perl script that will calculate your average hashrate and display the important lines in your ethminer log files: ℹ 21:19:58.840|ethminer B-) Submitted and accepted. ✘ 20:23:53.048|ethminer FAILURE: GPU gave incorrect result!` This script works on Linux and Mac OS X as the Perl interpreter is available on these platforms by default. For ...

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 connect to all nodes. This would be okay if they were to connect to all the nodes with substantial mining capacity, but I don't think all nodes report a speed. ...

there is a database of GPU different models and their hashpower (with the usage conditions) check http://www.mininghwcomparison.com/list/index.php

Try this one: http://cryptomining-blog.com/category/mining-hardware/ Though it is not perfect, it covers most of the GPUs.

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 20MH. Note that I originally installed 7.0 but I believe an NVIDIA's autoupdate updated me to 7.5. So even if you have 7.0 installed, try reinstalling it. Best ...

You do mention that you have specified the opencl switch at start. Did you specify -G in the ethminer parameters? This is required for ethminer to mine using your GPU. Here's the relevant ethminer --help : Mining configuration: -C,--cpu When mining, use the CPU. -G,--opencl When mining use the GPU via OpenCL. --opencl-platform <n> When mining ...

I'm getting about 25 MH/s with a GTX 1070. I'm not overclocking mine but I'd be kind of surprised to see 40, averaged over time. My understanding with GDDR5X is that the specs are better but the software is just not optimized for it yet.

If I understand you correctly, you're asking how to calculate the "lottery of probability P" of being chosen and the "ticket cost C" with PoS. I'm not sure what you mean by using hash rate and total difficulty to calculate these values in PoS - I'm not sure these concepts make sense in a PoS context. That being said, the "lottery of probability P," in PoS, ...

I was pretty sure the answer was already on here, but here is a new answer: Ethereum and Monero use different ways of hashing to secure the blockchain (Ethash vs CryptoNote). The computational difficulty of hashing depends on the hardware and the algorithm itself. For example, imagine if I measured how many pairs of three-digit numbers you could add ...

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 of shares and the pool will show your effective rate as being higher than usual. Conversely, if you're unlucky and submit fewer shares in a period then your ...

mininghashrates is a database with GPU hashrates that can be filtered and searched.

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.)

Without looking in too much detail, I'm going to speculate that it's due to the difficulty adjustments related to the originally planned Difficulty Bomb. (See: What is the "difficulty bomb" and what is the goal of it?) The EtherScan chart to look at would be the one showing how the block time increased in a series of steps (due to the increased ...

Check your drivers and make sure that you have it set to “Conpute” mode. Also make sure that you are using signed drivers with the atidag patcher to make sure any modded bios is accepted by the windows drivers. I was running at 31 Mh/s but with too many memory errors I am now currently running at 28.6 Mh/s with close to no memory errors.

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 Boost BIOS (via card BIOS switch). After some investigation I found that (using the Boost BIOS) lowering the core and mem clocks to spec rates (1257Mhz core, ...

You can use a Poisson table to determine how many blocks you can expect to find in a given amount of time. For example, at 1 Gh, the expected value of how long it will take you to find a block is 9 days (Network difficulty is ~800TH and you have 1GH/s, so 800TH/(1GH/s) = 800000 seconds). So in a 27 day period, assuming difficulty does not rise, you can go to ...

I have a hd7950 recently purchased used to fiddle with AMD mining, as I have only used Nvidia 1060 on Ubuntu up to now. Mine runs around 11.5Mhs stock. I havent tried to overclock it yet, but I believe its that slow as the DAG has grown. BTW 3G is fine for the DAG, Im mining right now, dual mining Eth and Sia on that card at the same time with Claymores dual ...

3GB is not enough any more since DAG file got bigger recently

I have the same problem. My card started at about ~19MH/s and after a few minutes it dropped to 11MH/s and stays there. Bought it last week to works as 3rd gpu into my rig; zcash mining seems more profitable for it at this rates...

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 work as random as possible. That increases the chances of the machine running the algorithm to find a solution that nobody has found.

This is a zcash hash rate list, but it is pretty comprehensive. I use mainly to check wattage usage.

I've yet to find a definitive answer as to why GDDR5X memory sucks so bad for mining, and I've been looking everywhere. It would seem to be a simple driver problem, but it must be a big enough issue because for the 1080 Ti's, they switched back to GDDR5 memory. I actually have 3 MSI GTX 1060 Gaming X+ which use GDDR5 memory, but get a big memory speed ...

Most (all?) mining pools will not show your worker until it has generated at least 1 share. If you are CPU mining, you will probably have to wait an eternity before you get a share. CPU mining is very, very slow. You need at least 1 GPU, and even then it might take several hours before you get a share and the pool displays your miner.

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 much a given hash rate will earn. 100KH/s is a very low hash rate. You should avoid cloud mining as they tend to be scams of one kind or another however if you ...

I have a 980 Ti and I only get 5 MH/s on Win 10. The GTX 610 is probably going to be way under that. nVidia cards are terrible for mining compared to AMD cards presumably because of the difference in how they implemented OpenCL. I doubt they are producing much more ETH than the cost of the power it takes to run them.
