He who bought an RX 5700XT to mine ETH, GG, you have a very nice gaming card but nothing else. Greed explotion!!!

Just to be clear here.

Profitability , right now is dead for almost all people living in first world countries. Mining is only profitable in places where you can get Electricity at around 5cnt/kWh taxes included (i say this, because in Spain we are taxed 26%) or solar power (which also implies investment and ROI to take into account).

According to what ETH devs have said, ETH 2.0 or total POS will come in January 2020. At most you may be able to mine until February or March 2020. Not more than that. Once this happens, any algo where AMD can do nice will be destroyed. ETC (Ethereum classic) will see it's hashrate (currently 9,3Th or 9300 GH/s) more than x10 the next day. So anyone mining that coin will see his profit reduced dramatically.

All people mining ETH, will throw their machines to anything remotely profitable in the ETH algo if there is anymore than ETC or ETH. If not, then they can even try to mine NVIDIA algos the way NVIDIA guys have been mining ETH for a long time. all those coins will get their profitability REKT.

So, is it intelligent to build a mining rig? NO. AMD or NVIDIA? NONE!!! GPU mining will die with ETH, because the mining coins will be flooded with those gpus. I predict a huge, brutally huge amount of GPU in second hand to sale by 2020. So if you are reading and you are a gamer, just push a little more your card. You may be able to get Nvidia o AMD cards to play for very little.

Add to that the fact that all not resistant coins are seeing ASIC take control, so that makes GPU simply a no go.

Do you want an advice? forget about mining as a way of making some money. You are just 6 months away from the end. Enjoy it as much as possible now.

nice comments all of you,

1º i don't think it's related to tweaking cars with software. Reality is people want 24 hours non stop mining rather than sometimes crashes by pumping some more hashrate. So i totally discard that. Moreover, software tweaking is not normally the most efficent since only applies configs that are "safe". And i don't know anyone into mining without flashing bios or investing a lot of time and effort in tweaking cards.

2º Mining with only one card is not profitable. Why? not because of the card, but because the whole extra Watts you have to deal with at profit time considering your gaming machine uses (big CPU, lot of ram, rgb lightning, big fans or even AIO or water cooling solutions. I don't see the point here. profit is next to 0. And also the return of very low amount of coin mined is neglectable.

3º I think this spike of 10% from 165.000 to 180.000GH/s should be ASIC. There is no other option. You cannot pump an already inflated hashrate the equivalent of 500.000 GPU at the same time. It's simply not possible. AT all.

4º Now, the option of people turning down machines, and after a period of time , put them online is possible, but how many people should do it at the same time to get the equivalent of 500.000GPU online?? No, sorry, that does not seem the answer.
And , BTW if you support the technology, you just continue mining even at a loss. If you stop, is because not only it's not profitable at that very moment, but also you consider the situation will not get better. Why would you stop mining and then continue doing it? you could have mined more coins and if it gets better, that would benefit you. So i don't get it.

5º According to ETH Devs, according to what has been said already, January 2020 is the time for the release. The problem is that i don't really know if they will just shut ASICs in the network, or will actually go total POS with 0 profit no matter what conditions you mine because they will reduce the block reward to 0.
Remember that inflation is a fact in ETH. The sooner they begin reducing inflation, the more value the coin will get (at least, that's how markets work). Many people say that BTC , once it's all mined, will pump brutally. Can this happen to ETH??

The answer to your post is very simple:

1º I upped the post because i was the creator.
2º Because i can do it.
3º Because it's an actual issue
4º Because opening a new post when there are related to the issue already opened is actually harming the community (FYI).

Now, The amount of hashrate has been increasing, WITH NO REASON but there are big spikes that offer enough evidence to discard that a big farm has "re-entered" the market. The ETH network difficulty has spiked 23% in the last 3 months. If you had to pay 23% more anything that you commonly use, wouldn't that be a huge spike?There is no big farm for ETH with 15.000 Gh/s. This is just a well coordinated movement to destroy profit for first world countries to make it more centralized and in control of some countries. And if that was not the question, it's obviously a matter of pure profit (if the price gets to a point were you can get profit, even if it's small, people was commit to it, in an stupid movement). The profit of mining ETH is nearly 0 in countries with 0,09$/kW taxes included. There are very few countries that can make ETH profitable, and those are China, Venezuela, Argentina, Indonesia, India or south AFrica, all of them third world countries or countries in evolution.

The profit is so small, the even big farms don't win enough money to maintein their taxes and electricity bills. i've seen 4 of the biggest in Spain shut down. There are no big farms in my country due to high electricity prices, at 0.16$/kW taxes included.

Did they close, invest on solar power, and open again? Yes. So well coordinated that in 3 days 500.000 GPU join the ETH network? No, that's not possible. This is a coordinated action.Is this a massive farm with ETH ASICS?? Maybe even Bitmain using their new products against GPU miners??

When GPU mining gives you 0.20$ per card per day, to see 15.000 GH/s join the market, is just a disaster. But this is the key question: even with ETH at less than 100$, we were still above 135.000GH/s. I don't think people are so stupid to mine at a loss. So the most viable option, is that most of that hashrate is being mined with solar power. 
 

it's clear in the quote. I said 15.000gh/s not 15Gh. 15.000GH/s in the GPU mining world are a huge amount of GPU's. Considering the most normal GPU card in all mining farms is the RX 570 and this card can do around 30mh/s, we are talking about an astonishing 500.000 GPU cards entered the ETH network in the last two-three days. Your data of 6 TH/s in 3 days is false, sorry. In three days it went from 165.000gh to 180.000GH/s. And yesterday, from 170.000Gh/s to 180.000GH/s.

We are not talking about big farms. A big farm cannot do that. We are talking about a very coordinated movement to crash ETH difficulty to the top, to make it less profitable and push people off due to high prices payed in first world countries, favouring third world countries such as China.

Thanks for the advice, but current situation disadvices to do that movement, though it will have to be done in January-February 2020 once ETH goes total POS. And you know what will happen right??

Brutally increasing hashrate on ETH. From 165 to 180.000 Gh/s in just 3 days. What da Fuck is going on???

Are new ASIC joining?? GPU mining at current prices is just NOT PROFITABLE in the 0.09$ taxes included (which is only possible in third world countries) . 15.000GH/s appearing in 3 days? It's simply not possible for GPU mining to achieve that number. What is happening???

in 90 days, the difficulty has increased a 23%. WTF!!!!

you don't need that info. It has already been done by others. BTC is mined nearly at 60% in china due to their stupidly cheap energy related to being a third world country. Is China a third world country? Yes. Why if they are the second country in the world with more rich people and nearly 40% of chinese people are in the 10.000 to 100.000$ income?? Well, because there are at least 500 million people poor which is 10 times more people than my country which are poor or nearly poor. That's why prices are low there.

Just to compare, you cannot live in Spain - Madrid with 750$ income. but in Shanghai or Beijing you can get with 750$ a flat + costs related, eat, transport, mobile and internet home and some nights going out. That's what tells you if China is a third world country.

BTC is brutally centralized and the chinesse are the ones taking profit.

no buys = more sells. Price drop and eventually more bear market which is bad for 95% of the people here, except for good traders which they don't care, they just adapt to the situation.

something should be wrong in your config. both of my 2x 6 RX 580 were using 850W from the wall at 1150mhz 850mv more or less and 1000mv mem. with 13 gpus you should be using around 1850W rock solid, not 2000W as you said. That is due to PSU ineffiencies. It depends on the type of PSU you use, the power it provides, if you have both of them linked and so on.  

Now, the point. You can undervolt your mem with this ideas.

1º you want less power consumption, not performance. So you go for the same voltage and same mem clock with all cards. That is at the cost of performance, so less mining power. My cards were tested individually. So, i would never apply the same numbers for my cards not considering i can extract a little more from each one. i know for a fact that all of them are giving the max performance at the lowest possible power consumption.


this are the numbers

401mh --- 1850W   59.10$ (profit) 55%  0.02682 (mined day)   0.8047 (mined monthly)   <-------- my config
390mh --- 1700W   63.19$ (profit) 64%  0.02609 (mined day)   0.7826 (mined monthly)   <-------- your config

This are average numbers.

This means that, in a investment to profit ratio, your undervolting makes sense. You use a bit less money on bills, but at the cost of mining less ETH per month than me. Who do you think is going to get more profit if the coin goes up in price?? And, on the contrary, you would win because you would be more power efficient which is very good when prices are low.

At a certain point, if the price scales, the more you mine, the more you make because that extra mined coin will be totally worth the extra electricity. In fact, i have two bios for my cards. One at 1150mhz and another one at 1240mhz, which adds like 0,3-0,5mh/s to each card.

with my config, with 13 cards, i would be doing like 406mh/s. With my 2x6 rig (12cards)  i was doing something around 376mh/s. I would never be able to obtain those numbers applying the same config for all cards.

by that time, i prefered to have more coins rather than using less electricity because it was worth. Now...well...my config would be more expensive to maintain. But if coin goes up, it would be worth that extra power.

Anyway, you can just stick with 850mv and deal with crashes or increase the ram voltage and forget about having to get the car at night to solve the issue. That's the difference.

there is a very spreaded fact that says that memory can work undervolted. My experience is that THAT DOES NOT WORK AT ALL.

To begin with, every card that i've seen is 1000mv stock on the memory (2000mhz on 580's , 1750mhz on 570's), so 850mv is an undervolt that can cause mem to not have enough power supply and crash. Moreover, this is going to happen if you overclock your memory.

So i bet if you leave it stock to 1000mv you will see less or nearly no errors.

You haven't told us your card,  asic quality, memory brand , etc, so not much i can tell you with this info, just what i said.

1150mhz for 850mv on the core, is also low. Most RX 580's will need around 887mv to work without issues though 850mv is possible for the core. I had like 6 of them around that voltage on the core (from 850-887mv). If the miner crashes, and reinitalises is a core that's too much undervolted. If you get too much errors , or your hash rate is low, or you get incorrect shares, that's normally mem issues.

go for 1150mhz on the core at 887mv
go for 2150mhz on mem with 1000mv

If with this parameters, you still get errors using HWinfo64 (or 32), this means your mem should go underclock. Then try 2125mhz and see. You must stay near 0. some errors, (small amount, can be accepted, less than 100 every hour). if it continues with errors , then 2100. This should be ok. all of my 12 cards could do at least 2100.

Normally, with micron mem you will probably do 2250mhz (all of my micron could do it, best mem for AMD). Hynix is tricky. Some will , and some will not get there. Samsung memory is really bad on AMD cards (the best on nvidia BTW).

i used custom bios + MSI afterburner to apply undervolt.

this cards will make you lose money. Almost 100% sure unless you live in a third world country where you can get kW at 0,06$. In that case you may get enough a month to drink a coffee.

This is insane. People are desperately poor, OMG.

NO. Altcoins are dead.

the normal issue: everybody undervolting memory.

DO NOT DO IT!!!! It makes crashes more often!!!

ETH will die before DAG size gets to 6gb.

But i totally advice you against investing into mining. Your profit will be next to 0 if you have 0,08$ per kW (taxes included). Above 0,10$ per kW (again without taxes) you´ll be losing money.

i don't think a guy that has sold RX 470 for 53$ is willing to invest in more gpu mining. Almost sure he forgot about it.

it's not profitable at all. you can make 0,2€ per day per card at the cost of big electricity bills and high room temps in summer. You could argue it's good on winter to heat up the house, but not in summer at current prices.

But is incredible for me, is to continually see the ETH network hashrate and difficulty increase.

Either three things:

Or people are mining at loses because they consider that in the future they can get profit if the coin bumps (mine to hold)

Or people have very very low price per kW because they live in third world countries where electricity is so cheap that the profit, even small, is important (example: Venezuela)

Or people are using ASIC (which the fuc*ing devs don't want to crash in the ETH network) and are mining 480mh/s at 850W which are numbers that GPU miners cannot even dream of.


So no, if you sell, you just give up. And it's the smartest thing to do nowadays.

some tips here.

1º DO NOT UNDERVOLT MEMORY. Specially if you are mining ETH. My experience is that ETH is a highly intensive algo that needs to work with ram. If you undervolt errors and crashes can occur.

2º Moreover, some ram needs more voltage to work. If you overclock and at the same time undervolt ALL OF THEM JUST NOT CARING ABOUT DIFFERENCES IN QUALITY, YOU WILL GET CRASHES. Every one of my 12 cards was tested individually with the max stable clocks at 1mv on memory.

3º this action allowed me to push ram to the max getting in some of them 2250mhz on the memory, which makes a huge bump in performance. To be clear here. a card doing 2050mhz mem and 1150 mhz on the core, will do something about 30 ish on ETH. If you can do 2250mhz it will go to 31,4mh/s. If you go for 1240core and 2250mem you can expect around 32 ish.

So, the only way to squeeze more performance is either this two things:

1º bump ram voltage to 1mv and test individually your cards to see how much you can do without too many mem errors. You can allow to have errors, but not much. ideally 0. but you can get around 1000/day. if they are micron, i can almost assure you that with 1mv you may be able to do 2250 on almost all cards, since micron memory is the best for AMD polaris cards. All of my cards with Micron do 2250mhz at 1mv.

2º if you want to get extra performance at the cost of more heat and power consumption, you can try 1240mhz on the core at 881mv or maybe a bit more (depending on ASIC quality of the cards).

there is no other way.

simple answers.

Can they know that a bios was modified? YES, ABSOLUTELY. I could do it myself. You only have to read the bios, and watch the numbers. A technician is used to deal with that numbers, so he will detect it almost instantly.i'm not familiarized with your cards, but with my sapphire cards (btw, the best AMD cards you can buy) i would detect the bios mod very fast.

Why is it necessary 85% fans?? my rigs worked almost 1,5 years without stop, and the worst card i had, the MSI RX 580 8gb ARMOR, was the only card that needed 75% fans only in summer with ambient temps in the room of 33ºC and it never went above 75ºC (which is a fairly normal working operation for this cards).
All the other cards only needed 35 to 50% rpm fans. Depending on your place and conditions, this actions may vary. For example, my 2xMSI RX 580 8gb GAMING X only need rpm at 40% to hold 55ºC operating temp for months at 33ºC ambient temp during summer. They are very good , but Sapphires are better.

Huge amount of scammers today.

Technical analysis says we are very near a dump again. BTC will dump to 8,5k. ETH is seeing huge resistance in the 225$, which means noone values the asset more than actual value. This is NOT A BULLRUN, JUST A BULL TRAP.

Go and search for TA. Don't think WHAT YOU WANT TO THINK. Think what it is, and act consequently. This situation is a clear BEAR MARKET AGAIN.

If you don't act right now, you´ll suffer.

mmm....big farms react almost instantly. changing their algo can be done almost automatically with their software. There are people outthere that can switch coins with one click. Moreover, they can also tell the computer to switch to certain algos during certain times. They load profiles directly on the miner (not bios) and as soon as they load the miner, the program gets the card working.

I myself was able to switch from ETH to ETC miles away from my house when i was mining back in 2017.

Now..... i don't normally help people with issues, but i´ll give a few tips in case they can help.

the sweet spot for RX 470-570 (mines were 570's ) is:  1150 mhz on the core, 2100 mem. AFAIK 470 and 570 are almost the same card, but 570 is a bit better, to be honest.

My experience is that you should not undervolt the memory. My Sapphire RX570 nitro+ cards did crash a lot if i undervolted the memory, so i left them at 1000mv stock. 850mv on the memory...well...maybe it's ok for 2000mhz, but take into account that RX 570's nitro+ at 1750 stock mem clock had 1000mv stock.

Now, the voltage.

i have 3 RX 570's nitro+ 8gb

1º 1150/2250 831-837mv core/ 1000mv mem 31.4mh/s
2º 1150/2190 831-837mv core/ 1000mv mem 30,8mh/s
3º 1150/2125 831-837mv core/ 1000mv mem 30,3mh/s

They were stable for months at this settings. I tested for two days all of my cards before going into the mining rig. i programmed the bios in all of them and i tweaked as much as possible the voltages except for memory. ETH is a pretty intensive algo with the memory, and i prefered to forget about having problems with undervolting. I suppose your undervolt saves you some money.

my 2x6 mining rig are off. and they will continue to be off for a large period of time. I will only turn them on if i can get 100$ profit per month or more after electricity bill, which i think will not happen this year.  At current prices , and the very expensive cost per kW i would be losing around 15 $ for month with bills of around 350€ or a bit more in summer due to fans having to work hard in my room to deal with heat, specially where i live.

So....yeah...mining is not worth for me.

There will never exist an altcoin season like the one of 2017. Why? Because by that time, BTC predominance was 55%. Now it's 66% and increasing. This means many many people are leaving altcoins and investing directly into BTC.

Want numbers? here you are.

While BTC is like 3-4% profit in last month in absolute terms of 30 days (not max and min values), ETH has dropped 24% in same BTC conditions.

Forget about Altcoins. Most of them are going to die. 95% at least. BTC is getting big investments. And Altcoins only see massive sells across the board. So deal with it. And do it now. Your money is in danger.
