Topic: I Bought 150+ GPUs for Ethereum mining. Think I'm Insane? - page 4. (Read 2711 times)

Should bout gpus for grin/beam lo

The motherboard I have is an Asrock H110 PRO BTC+
Of course, I've done this. Each rig is separated by memory type. Samsung/Hynix/Elpida. Strange that you don't have this issue. Wonder if it's something to do with the motherboard then?

I am really sorry to disappoint you now, but I am running 12 AMD GPU rig almost with no problems. Uptime is around 6 days. Using Windows (as it's free and straps are working; once strap function is available in HiveOS I might switch to it).

My setup is a little different though; MOBO is Gigabyte's

upd: I re-checked your first post and haven't found anything about your MOBO lol. I had a feeling you use different one or mentioned it in some other post.. w/e

my piece of advice is to distinguish each GPU's bios and put GPUs with the same bios in the same rig.

This would help you to flash them much easier.

It's a fixed amount but PA is weird They charge a 'supplier rate' and 'Distribution rate' So while my Supplier rate is .04599c/Kw hr the distribution is what it costs to get that power to my house. So my total is .10C/kw. There is no Seasonal rate or anything.

How many GPUs do you have per rig using Claymore straps? I can't get more than 5 to work. No idea why.

I know what to do, I've owned RX580s previously and BIOs modded them myself. Spent hours tweaking. With Claymore's v14.6 I was REALLY hopeful that it would simplify this entire process without the pain of BIOs flashing each card, then tweaking each card for Memory voltage/overclock based on whether they can handle it or not. Looks like I was too hopeful.

I found I can reach 5-GPUs and Claymore STRAPS work fine. Anything after the 6th GPU crashes regardless of anything. I've tried different drivers 18.6.1,19.5.1 and 19.6.1 all same the problem. Tried various C++ and .Net framework same crash.

Looks like I'll just have to BIOs flash them myself.

I had a farm of RX570 and RX580 cards, I did not know any problems at all, as soon as I managed to sell them at a better price. but now I look even at this course, they are not yet relevant. better I think to wait

now it is very profitable to take AMD rx570 SERIES graphics cards, they come out at $ 145-150 which is very cheap for such a hash rate. concerning nvidia, they are cheaper, too. and it turns out not a bad farm

mining on windows is nothing but headache and way too much work, with the number of riggs you are dealing with is a full time job and than some. the down time alone will eat up your profit quickly if i were you i would look into some linux distros like ethos smos.

i am a hobby miner IT guy myself and been testing mmpOS and i really like it it's been super stable for my AMD cards

Best of luck!

about your power cost, is it 10 cents or 1 cent?
most power companies in US charge extra premium after 1000KW or so, is yours a fixed amount?

Claymore straps are fine, 32 mh/s for my Micron babies with Claymore straps is the best I could ever get from them.

I wish all the luck to the topic starter, 10c per kWh doesn't sound attractive though

LOL you bought over 150 cards and can not handle it? If a AMD card has a Modified bios, windows give you the error 43. Apply Pixelpatcher and reboot. If you put another card in this rig, then you must apply the patcher again.
 I Think you have bought old mining cards and some has modified bios and other has original bios.
Sorry bro i found your thread interesting, but now. These are basics and all know that for long time. And forget the strap function from claymore, flash bios is the best way.

Windows version does not matter, all work fine

I only could say wow, you are ready to get big rewards With all of your hardware, you can get a big hashrate, and if you are mining small coins which can increase later, I am sure that you can double or even triple your profit when the next bull market comes. But I wonder why you don't buy RX 570 or RX 580? Is still too expensive right now? Because I heard that some mid-end GPU hardware was down because of the miners selling their hardware and that makes the price of each series get down too for the price.

Very powerful farm, really quite insane. The price you turned up is very good....
I have a question - for mining, do you rent a room or do you keep it in your basement \ house?
Just interesting about amount of costs.

Because I can spend say 15G and invest in Ethereum at the current market price of $260(June 19') and get 57 Ethereum. Or I can put 15K into mining GPUs and earn 16 ETH a month or about 200 in a year. What makes more sense? yes there more involvement with mining, but it takes risks to make money. With what I'm putting out for investment is minimal compared to the returns for cryptomining. Plus I'm just an IT/Tech enthusiast also work as IT for a living. It all goes hand in hand.

Right now I'm trouble shooting the RX 470's. I got one rig of P104-100s up and running hashing away fairly easy.

I cannot get the newest Claymore 14.6 STRAP function to work without crashing. Unsure what's causing it. Now there is a bit of a caveat Since these were used some cards were BIOs modded others left stock. I put whatever was BIOs modded back to stock from other GPUs that were stock, however, I noticed in windows that quite a few GPUs have the 'ERROR 43' in windows which can only be fixed by applying the ATIpixel patcher.

Setup:

13x Rx470 4GB (Stock BIOs)(Hynix, Samsung, Elpida)

Asrock H110 Pro BTC+

G3930/4GB RAM/EVGA 450w PSU (for motherboard)

Delta 2400w Server PSU (For GPUs)

Windows 10 (1903)

AMD 19.5.1 Drivers



Now when I tested the STRAP function with a single card, works fine. Will launch and I'm seeing good hash rates of 31mh/s~. However, when I plug in all 13x 470's try the STRAP feature, it will get to 2nd GPU applying STRAPs then Windows will crash and restart itself. This happens every time without fail. Now if I only apply it GPU 0 the STRAP then works fine again, however applying it to GPU 0 and GPU 1 it will hard crash and restart windows. Trying GPU 0 and GPU 2 results in the same thing. Also, note that RXBOOST works perfectly fine. The cards will hash fine with stock BIOs or even Modded BIOs using RXBOOST.



So Far I've tried

Raising voltages for Core/Memory or just leaving it stock. Doesn't matter.

Updating Microsoft .net framework and C++
Flashing various Stock BIOs(found online) and even Modded BIOs.

Different Windows versions 1809 vs 1903.



Furtherest I've gotten was 4-GPUs using the STRAP function. Once I started adding the 5th and 6th or more it would crash and restart windows. My Assumption is that it has to do something with the BIOs and the ATIpixel patcher? However, I'm unsure how to remedy this since only 1 or 2 GPUs seem to not have the error 43 in device manager. I'm unsure of this and wondering if anyone has encountered the same problem.

you are making 9$ per month per Card after electricity (at best), and that's considering you don't have to pay taxes or you evade them.

I guess i will never understand why people do this kind of frikin investments.

Let a man dream!

You should put up a chart with ROI estimates and each day you mine and sell tick off a box on the calendar. When you finally pay off your cards or whole rigs, put a picture of the calendar with the marked boxes in this thread.

At $53 you should be fine! That is a great price even if a few die along the way.

Most of your costs must be electricity, maintenance, and probably a whole lot of time.

I don't know why, but I really enjoying seeing a full mining farm set up. It's like my mini mining rig but on steroids

^ This. All equipment can be depreciated but then if you sell it, it has to be sold at "fair market value" then detected as income. I'm not an expert on how that all works. That's pretty much my plan run these babies until they die and dump them at E-waste. Considering ROI time, and possible crypto-booms I'm really hoping for good income from them even after they can't mine Ethereum anymore.

Updated the OP with more rig pictures build in progress. Another 52 cards are enroute and P104-100s are racked! Currently testing 13x RX470s and 13x P104-100s.


because when you're dealing with 150+ GPUs that's an increase of cost in thousands of dollars. RX470 4GB's offer the lowest cost and still perform well-meaning faster ROI.

Rx470 8gb why not ?

well I will not say that you are crazy, but I'd buy a bit of Asic + graphics card. It was necessary to distribute a little Finance

From a tax accounting perspective any sold GPU will have to be reclaimed by IRS if you took an equipment deduction tax benefit. Best to run them down to the ground. Geez you small time miners are amatures.

If the market goes up. Not only you have to Roi on dollar amount. You must also roi on crypto coin amount if someone sold their coins to buy gear.

If dollar amount is roi but crypto coin amount did not roi then you lose bc of miss opportunity of just holding coin would have offered better gains.

This does not apply to him since he took a 16 percent loan as a hedge in case market goes up he keeps his coin gains but pays a 16 percent interest as insurance if market goes up.

If market goes down and stays bear longer like over a year than best if he did not take a loan and just sold to hard cash for hardware or just kept his cash to buy coins lower
