What's the best hardware for mining ethers?
For the highest hashrate per GPU, the answer is the AMD HD 7990 (minimum hashrate 43 MH/s), followed by the AMD R9 Fury X (minimum hashrate 28 MH/s).
The HD 7990 was released in 2013 and is harder to purchase from stores as this series has been superseded by the R9 series released in 2015. Internally, the HD ...
The DAG started at 1 GB at the time of the Frontier launch, and increases by approximately 0.73x per year. That puts the current size at roughly 1.35 GB as of mid-January 2016 (feel free to comment with an exact link if anyone has one).
Following the same crude approximation:
The 2GB limit will be hit around mid-December 2016
The 3GB limit will be hit ...
short answer too, that will take the exact opposite stance as @nicolas-massart ;)
in the long run you'll be always better off mining solo, ever because you get uncles and pay no fees
pool mining reduces your variance, period.
this reddit post is quite interesting, it's basically @vitalik-buterin asking as to why people mine in pools.
It's not true for ...
Even now, GPUs are not used for the EVM. Mining is simply deliberate busywork, a way to spend computational resources with an easy way to prove that it happened in retrospect. Smart contracts and the EVM are totally done by the CPUs of every full node.
Post-Casper, GPUs likely won't be used at all. Casper does not require heavy computation, let alone ...
Short answer : don't try to solo mine with less than 100MH/s.
You will almost never get reward as, during the time you will spend mining, the difficulty raise will lower your luck of mining a block so much that you will finally never mine one.
: note this value gets higher as the time passes.
Not sure if this question is off-topic, but broadly speaking, there are a few things that affect a GPU's performance given a particular algorithm being executed (for mining Ethereum and otherwise), assuming adequate power being available:
instruction pipeline performance,
The faster the GPU ...
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 ...
Generally speaking, the answer to this question is almost always "Yes."
I've yet to see a situation in which this was not the case. You may have difficulty (but not impossibility) mixing CUDA (Nvidia) and OpenGL (AMD) mining modes, but even Genoil's ethminer is equipped to handle this case.
My 2 x Gigabye R9 390X + motherboard, CPU, drive + fans consume ~ 700 watts (measured with a power meter at the wall) - see Is CPU mining even worth the Ether? . My GPUs are only slightly overclocked.
Your 390 and my 390X have a 275 watts thermal design power (TDP) - see http://www.pcper.com/reviews/Graphics-Cards/Sapphire-Nitro-Radeon-R9-390-8GB-Review .
You might have a misconception here:
running a full node does not require mining and is only supporting the network without you getting any (monetary) reward. It has no high bandwidth requirements (runs on my private internet access and I can still stream movies etc) and almost no CPU or GPU requirements (unless you sync from scratch then it takes a bit of ...
For people who're having this problem with a headless Windows box:
ethminer must be started from the system, not via Remote Desktop and there should be a dummy plug or a real monitor connected to one GPU.
This is how I solved it:
create a bat file which starts ethminer
press Windows + R -> type "shell:startup" -> ENTER
put a link to your .bat file in the ...
Finally fixed my issue. Here's what I had to do:
From the BIOS, I had to set the motherboard to use PCI-e graphics (it was set to use onboard graphics).
I had to make sure I plugged any monitor into the GPU on the 16x PCI-e slot (I have an ASRock BTC Pro motherboard, and there is on 16x PCI-e slot, and 5 1x).
With that done all seemed to magically work.
It's very easy to calculate reward probability with a little information. What is the Network's Global hashrate, Blocks/day, and your percentage of the global hashrate. Because of the law of averages and luck involved in hashing algorithms, your variance in hitting a block time-wise will average out over the higher amount of set data.
Simply divide your ...
I've gone to the link http://www.mininghwcomparison.com/list/index.php?brand=both and filtered for 7990 and the top 5 entries relate to Ethereum mining:
Clicking on More Info on the fourth entry, then clicking on Config provides the following information:
So this miner is using a Powercolour HD7990 with the core ...
Based on your 19 Mh/s figure and the Ethereum Mining Calculator, you should be getting about 0.0040128644455329 ETH per hour, 0.0963087466927896 ETH per day or 0.3210288 ETH for 80 hours.
As you are mining with Nanopool, you should be able to check your statistics from their statistics page. Here is an example showing the account for a miner with 1,428.0 Mh/...
You can do a few things.
Move your keystore to the new rig
If you move the whole folder, the new rig should mine to the same etherbase by default.
Set the new rig's etherbase to your wallet or old etherbase
The command in geth is miner.setEtherbase(0x123...)
Transfer all of your ether to your wallet, and start from scratch on the new rig.
No. This is not possible, nor is it a good idea.
Individual computers are often not powerful enough to mine Ethereum blocks.
This is why people mine in pools (for example nanopool)
Mobile phones have significantly less powerful processors (and graphics units) so as to keep costs down.
The issue is to do with the DAG file size, which is loaded onto GPU memory in order for the ethash algorithm to call pieces of it during the hashing process. The DAG file grows with time, so as it gets bigger graphics cards will become obsolete if they can't hold the full file in their memory.
While this seems like a pain, this memory-intensive ...
Just a side node, I use ArchLinux on all my devices, but when it comes to mining I just use a stock Ubuntu installation because they have the best proprietary driver support.
So without answering your question regarding the driver itself, I would recommend stepping out and (if that's possible for you) consider running Ubuntu and maybe you have the chance to ...
To my knowledge there aren't big differences in drivers version, buy ymmv
On a side note, you can check this website for a list of configurations / drivers info and hashrate.
Please note that the reported hashrate is what it is at the time it is reported so it's rather useless in my opinion since the difficulty changes over time, etc. I mined at 23MH/s ...
