Topic: I Bought 150+ GPUs for Ethereum mining. Think I'm Insane? (Read 2728 times)

it is very difficult to lose on video cards. They can also sell to the automotive industry, after mining. Here is Asic here is this roulette, Igar 50 on 50.

1000mV on memory is a complete waste of power and building unnecessary heat. Its not just the powersaving its bringing down temp as well

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


These cards easily hit 32~32,4 with following OC (hynix)

1180/2150
850mv core/ 850mv mem

--REF 30

I have also 4gb version which runs for months without any issues

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.

 

error 43 and you can´t solve it XD LOL noob

how long have you been preaching the end of mining? Please do us all a favor and just go. become a gardener or similar.

It`s possible to put 13 RX in one rig, but as for me - the optimal is 8 GPU per rig with Vega, 1070 or higher, and for RX450-580 or 1050ti-1060 - 12 GPUs per rig. This allows you to use one PSU per rig.

That's why the ignore user function is usefull

I recall there being driver limits with AMD cards, never tested it myself though. I never put more than 8 in a rig myself. Those boards with 8 or more pci-e slots came out more or less when mining was getting unprofitable anyway. I saw no point in investing in further hardware.

1000% wrong.

Not so long ago people speeding lies about 8 being the limit, I thing the are lying because they don't know, not intentionally.  But then there is very few real info and lot of lies. So maybe it is intentional to scare people away by putting out lot of bullshit.

And then Metroid is trolling hard for years now.

Why? We have a rig with 13 RX550 running.

With the current markets the way they are I wouldn't have done this, especially considering those cards are basically only good for Ethereum, which is going the way of the dodo. It's not just those cards, I wouldn't invest at all in GPUs right now. While BTC has almost tripled in price (it was at one point) since earlier this year, altcoins have not enjoyed the same benefit, which is where we make money as miners. Revenue is almost exactly the same as it was 6 months ago. Static revnue while BTC increases in value means we're at equilibrium.

Mining popularity has also skyrocketed, which in turn means in order to get very meaningful profit again, we would need to see a huge surge in alt/btc prices, to roughly around 50k. Assuming some of the altcoins also see the benefit from BTC. I can't imagine that happening anytime soon.

We've seen almost no new profitable pastures besides GRIN and that was knocked out within about a month and a half. Usually we get six or so per year. Formerly profitable coins are being taken over by ASICs and FPGAs with most devs not caring about their mining community disappearing.

People here seem to not understand that it's not just about being profitable. You can be profitable with 0 cost power (you shouldn't be mining with GPUs anyway with extremely cheap power), but hardware depreciates in value and most GPUs aren't going to see recoup without a huge surge in price before they're outdated again by newer hardware. Furthermore those GPUs are only making peanuts and you need tons of them to make any sort of meaningful profit (for you as a person), the profit per unit just isn't there.

ASICs have been the only hardware worth investing in for roughly the last year or so due to the hate they receive and lack of interest from a lot of miners, as well as the bloated state of GPU mining due to popularity.

It's just a matter of time for this to get fixed.
Also, you can't put 13 RX cards on one rig. The 13th card must be an Nvidia.

Some new cards are coming with a mining block, commonly known as error 43 if you modify their bios and atikmdag-patcher won't work on them. Probably manufactures dont want the bios of the cards to be modified anymore, but the interesting thing is that the card if not modified will hang every now and then if mining.

This is probably the end of mining as we know.

I tested the wattage for 1000mv memory and your insane for 13 GPUs that about 2000w! I'm achieving 390mh/s~ @ 1650w-1700w~ and just a little tuning for the GPUs. That 300w extra per rig and I have 11 RX470 rigs so thats an extra 3300w! I'd rather suffer some crashes or restarts tuning and finding stable wattage then that.


Luckily I don't have to drive anywhere since it's in my garage simply a walk. However I do still get a little stressed or annoyed because when they do go offline I don't know why, which is the big problem. I very much just want to achieve some stability but right now I haven't gone a full day without at-least one rig going completely offline :\.

@OP

At 53$ a card, that was clearly dirt cheap. I'm not sure I would have pulled the trigger, but you seem like you played the trading card well.

I always enjoy looking at other people's farms and rigs.

However if I'm honest, I do kinda see the end of GPU mining coming relatively soon, it no longer makes that much sense to me. Profits are small if not negative...especially with global warming, no one can ignore the fact that running huge farms is just bad for everyone at this point.

That said, I still mine to this day, most of my gear was purchased in 2016/2017. I personally still run about 40 of those sapphire cards (mix of 470/570s) at home in a dedicated room, but strictly on solar power. I developed my own script that monitors what my solar inverted is putting out and turns rigs on and off depending on how many kW I produce. It's been working super well for the past 9 months. I make about 4-5$ a day with 0 electricity costs related to mining.

Good luck with your operation.

The funny thing is that this is how I felt when I ran a large GPU farm. I still mine but with a few GPUs here and there and mostly for fun. Basically only betting on ETHBTC going to 0.05BTC one day and will sell it all for BTC and Hodl that.

I remember the stress of having GPUs crash and I had alerts set and was awoken many hours of the night. And when I wasn't home I kept getting alerts about crashed rigs and had to drive home, reboot the rig, and drive back. This got very stressful during the $5/day/GPU when there was alot of profit on the line.

Now that the profitability is much lower you can sleep throughout the night and not worry, because a crashed rig doesn't cost you as much as before.

It's the summ of all three together 
Some people mining at a loss, some have very, very cheap electricity, and there are some hidden asics with a company (everyone know which one)

You have to consider people with a large amount of GPUs and Asics, with 0.05 USD electricity, it's very profitable if the guy or company have 1000 GPUs for example

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.

He maybe changed the cards to the new Radeon Vega or even Rx5700 with Gddr6 memory now that the Dag epoch is at number 272.He was also smart selling them because Eth will not be mined anymore with these cards from April 2020 where the dag will be bigger than 4GB.

I dont sure that it was in such a way. Probably he changes GPUs. It explains why TS telling us about GPUs but not about rigs. Or may be these GPUs were bought from different sellers(and the price is just average).
In any way it is nice deal. Even if TS would decide to sell it - he can get profit.

The person who sold all these 150 gpus was relieved from heavy sleepiness duty ehhe

He sold and took a long vacation and never looked back. This person was finally unchained.

You trolls will never understand what freedom really is until you do exactly what this person has done ehhe

This person enjoy and understands what freedom really is ehhe
