Yes RX580 is more power hungry then RX570, my best performance rig for 6xRX580 is 710w at 188mh. Lot depends also from card,memory and BIOS modification, like the sapphire Nitros and MSI gaming uses the least power.

Yes still seems quite low , just a sample http://prntscr.com/p2l7f8 , these are the RX580 4gb. Is your cards modified? RX580 8gb memory clock max is 2250mhz so you can try push a bit more. Also at overclock setting where is mem tweak tool insert value 30. If still face issue you can pm me and i could help you when will have free time.

How many gpus you have 6x ? If so hashrate should be over 185mh/s . Do you have screenshot of your OC settings?

Yes card seems has dual switch, just flick other side and it should work, after the system is booted flick dual bios switch back. And flash the card as usual.

Thanks mineshop.eu - I will give it a go later as me "Free Trial" is coming to an end with SMOS (which is fairly easy and straightforward to use)

Anyone have any personal opinion on what to mine with 580's?

I am in the process of saving up now for an NV rig...

Thanks

RX570/580s are most efficient for algorithms like from most popular coins Ethereum and Monero have.

I think it is possible to use any equipment with free power, just calculate cheapest price per hash and fastest return will be your best option

Really depends on your taste. Havent used SMOS for while now, as i switched on hiveos and very happy with it. Just in that time when i started to use it was much more advanced. Dont know if SMOS has integrated same main features as hive does, but if they do then hive is always first to update their software with latest features like telegram notifications, aggressive undervaluing, mem tweak tool....etc. Would suggest you to try it out, at start it seems very complicated, but when starting to use its very easy.
I have made installation guide also https://mineshop.eu/2018/07/27/how-to-install-hiveos-and-setup-for-mining/

You still save more if you would use original firmware. Reduces your power usage with asicboost and increases hashing speed. 2% from for example 18th = 0.9TH is for hive. Do you know is there any firmware without dev fee for Antminer s9?

Bitmain is locking down latest asics, so not possible to install hiveos on them. But they do have great software for the Antminer S9 i did a review on my channel.

i am running 12 gpu's and 20 ASIC's -- now I know I have considerably more hash rate on the ASIC's the GPU rigs were more expensive but they do use less power but they also make me way less per month than the ASIC's after electric cost. The only advantage I see to using gpu's is their versatility - something ASIC's have very little of. Can only switch coins if its on the same algo and if they do a hard fork that ASIC becomes a huge paperweight.

in the end though - if the electricity is free, anything will make him money - it becomes a point of which will make ROI first then.

I totally agree. crypto is very unpredictable and it is a gamble in either gpu or asic. You just dont know which direction it will go, as there is times gpu is more profitable and time where asic is more profitable. The easiest way i would say is calculate by current profitability , for example take 5000usd and calculate which equipment will be bringing the most returns and if asic would bring only 10% or less then gpu i still would choose gpu. Just cause of longer life cycle. Also if went for asics then only Bitcoin, as these miners are so advanced now, that new and much more efficient miner is unlikely.

If free power then "all in"
Latest Bitcoin miners would be the most profitable like Antminer S17 , M20s, T3....etc . Only because that Bitcoin has been a good price pump, also you have to know that these miners are lot more expensive and in some cases overpriced as it was when BTC price was hoovering around 3-4k.
GPU  miners could be faster ROI if the tide changes direction as they are still very cheap compare to latest BTC miner.
The easiest way to calculate is price per hash if free power, that way youll get the fastest roi.

We will have some introduction about staking, staking in block chain isn’t anything new. It has been talked for a while now , and also one of the top Block chains Ethereum are trying this to implement since 2016. So I will be staking some ATOM tokens on Cosmos block chain and will be showing how i am doing this. Cosmos is quite new block chain , or what people call in 3.0 block chain. Where they have some unique features where you basically can plug in any block chain into Cosmos network of block chains and make it more efficiently. In few words how I understand staking in simple way. In Proof of work chain security, you have capital , you buy for example Antminer S17. Than you connect it to mining pool, and by doing this you get block rewards depending on how big hash rate you have. So in the Cosmos Proof of stake security, very similar. You again invest your capital and buy Atom coins. Then there is these validators , similar as pow has mining pools. You send your coins to these validators trough smart contract, which is called delegation . And in this way you get part of the block reward depending on how much Atom coin you have, the more Atoms you have the bigger piece of “pie”.

So lets get in to in and stake some Atoms. First of all I would recommend you to use secure hardware wallet for this as ledger nano, what I will be doing. You want to download Cosmos app in ledger nano app store. If you don’t see it in app store you might need to enable developer mode in your settings, as it is still in development. For simplicity purpose i’m using web wallet where I will be using my ledger nano to access my wallet. You can find multiple cosmos wallets  in here https://hub.cosmos.network/

For this tutorial ill be using web wallet from this list https://lunie.io .

The next steps are very simple :

open this web wallet with your ledger nano device
you will see your wallet address there, transfer some ATOM tokens to it.
When ATOM tokens is in you wallet start staking
Click on Staking tap, choose validator you want to Delegate.
Enter amount of tokens you want to delegate and confirm transaction with your ledger nano.
It is very simple, check out the video down below this might help you more.

As soon as you will delegate your coins you will start getting block rewards on amount of coins you have. There is no fixed block reward on cosmos block chain, it will be an average 7-20% yearly. It is calculated compound interest as I would say. Depending on how many total Cosmos network ATOM tokens are staked, if they will be less then 2/3 of total amount Atom. Then the block rewards will be higher closer to 20%. If staked ATOMS will be more from total of 2/3 then you will get closer to 7%. Also you need to note that if you want to finish staking (delegating) your coins, it will take 3 weeks to arrive back in your wallet. But if you want to change to delegate your Atom to different validator it will be done without waiting. I hope it was easy to understand as it was for me 😊

Anyone has the benchmarks for mining Zilliqa  ?

If you are new to crypto currency mining or you want to find out what is current profitability in crypto currency mining , you want to stick around for this one.

Most of you who is in mining or has ever wanted to invest in mining here is for making profits. About 99% miners are looking to make some kind of profit in crypto mining, only about 1% or less here is for supporting networks. Mining might be high risk and high reward business category. As it is very unpredictable it is hard to tell what you will be earning after 1 week or one month. We can only look into mining calculators today and see what is the profitability. Because tomorrow crypto currency which you are mining, price could collapse or skyrocket. Who has been in crypto for a while now , will understand what i’m talking about. Mining profits does depend on few factors like :

• your equipment costs
  
• mining software efficiency
  
  • your equipment efficiency
    
  • your energy costs
    
    • do you have any extra costs like (rent,security,how expensive is your location, equipment cooling costs)
  
  As in any business you are looking for your ROI as soon as possible, and doing most efficient way will always be the most less risky way. Let me give you and example 2 guys (John and Noah) start mining at the same time , they buy same mining equipment for the same price. Lets say Antminer S9 , John is mining from his house garage and pays 10c for 1kwh and the Noah sends his equipment to data center and gets deal for 5c kwh all inclusive. Of course the Noah whose power is 5c for 1kwh will do his ROI much faster, so for him it will be less risky investment.
  
  Always this is not the case and there is possibility that newer mining hardware will be released. In that situation both of the guys might loose their investment , as the new hardware might be more efficient. And there wont be any profit using the previous generation hardware.
  
  Im in mining business for over 3 years now and have been trough up and downs. Have gained a lot of experience by mining and also distributing hardware. Have made big gains and also very big looses buy buying large quantities of asic mining rigs. Asic mining is the most dangerous, but people still do it as it is sometimes more rewarding then gpu mining. A have got burned a lot of on the asic equipment, but not so much with gpu miners. The beauty about gpu miners is that if you choose the right hardware there is a lot of variety coins of to choose for mining. And i could bring you stable profit.
  
  So before you get in mining , do your business plan first. Do all the calculations, think all the details trough, all the small expenses. Cause everyone case is different, someones power might be slightly more expensive. But he is using somewhere else the heat produced from mining, and saves other expenses like for example heating or growing tomatoes costs. Don’t forget also to check current mining equipment profitability, best sites to check is :
  
  https://whattomine.com  for GPU mining
  https://www.asicminervalue.com for newest ASIC miner hardware
  But be very careful about asic miner profitability, dont get flashed about seeing high profitability rating. Always remember if new miner is released on preorder, the profit will be much lower when you will receive miner. And the second thing that newer generation miner lot more efficient miner could be released by different asic miner manufacturer. In that way you might not even get your invested money back. If i would suggest Asic mining , i would say that choose to mine coins like Litecoin or Bitcoin. Because these coins are one of the oldest, and the mining has got very advanced on them. Newer generation miners wont be so often released and wont be as highly overate profitability.

  Did i miss anything ?

This price would be acceptable late 2017 or early 2018, when the mining profits where booming. The brothers rx570 and rx580, prices lot cheaper as they used to be. Got some RX570 sapphire pulse 4gb the other day for 115euro a piece.

Well this is advertised as mining card  , total bs.

Nvidia is great on mining algorithms , except Monero . And AMD from big cap coins Eth and Monero. The problem with most of Nvidia cards is that they are so damm expensive, and in most cases when you calculate hash per usd ( amd almost every time has better ratio). I have in my farm mostly amd rigs , just cause i was focused mostly on ETH and some times few rigs on Monero. Now starting to buy also 1660ti cause they are so dam cheap for grin coin gps per usd. I do believe in Grin , so thats why i mine it Have 60x 8gpu rigs in my farm so far.

man what a waste, ill rather buy 1660ti which is lot cheaper and will bring more grin. The right price could be at around 150 bucks.

Ill rather buy 3x 4gb versions for that price. Which will be lot cheaper price per hash.

Sapphire 16gb RX570 mining card testing and review. So this card was released from Sapphire about 5 month ago and currently are priced at 329 usd on their website. Which to me seems quite expensive after i have done some benchmark testing. I can see that this price has dropped as previously priced, couple month ago it was at 399 usd.

 

I’m not surprise that the price of this graphic card is drooping , as the mining profits are not just great currently on most of the AMD cards. Also the performance for mining isn’t great on this graphic card. These are the benchmarks we where getting on this graphic card :

ethereum 31.5mh/s
Monero 900 h/s
grin coin cocaroo 29 (1.8 gp/s) cocaroo 31 (0.4 gp/s)
This card has the same base line as RX570 and it has extra 16gb gddr5 memory. Currently RX570 4gb trading at 100-150usd which is more then twice cheaper then the 16gb version. This doesn’t make sense to me that this card is trading twice as expensive as the RX570 4gb version for about the same performance in mining. Yes i know that Sapphire is advertising this card as for mining grin coin on mining algorithm cocaroo 31. Which needs high end cards and at-least 8gb of memory , also this algorithm is for asic miners. But currently we do not have any asics for Grin out there, so you can use these graphic cards. This 16gb RX570 on this algorithm is very efficient yes, it does the same speed as 1080TI. But i have a really good question is it really worth it, even if it is twice as cheap as 1080ti, No it is not. The profitability is just not there. It makes more sense to buy for example (1660ti which is lot cheaper then RX570 16gb which will bring in more Grin revenue mining cocaroo 29 ).

1660ti mining profits mining grin on cocaroo 29:

Sapphire RX570 16 mining Grin cocaroo 31

So overall my thoughts on this card is, it must be some Sapphire marketing trick. Where they are trying to sell their unsold RX570 graphic cards. Where they have added 16gb more to just get rid of them. Don’t get me wrong i would also buy this card if it was priced same price as RX570 4gb as mining performance is nearly the same.
