2  Alternate cryptocurrencies / Mining (Altcoins) / Last year I started a 200+ GPUs farm for ETH mining. What happened? on: June 05, 2020, 12:04:49 PM
Hey Guys,

So last year around this time I started a post, https://bitcointalk.org/index.php?topic=5153622.0 about starting a fairly large GPU mining farm by myself. I wanted to share today what exactly happened, did I ROI? Did I quit? Market crash took out my farms profitability? It's complex but let's start the Journey.

My mining farm
https://www.youtube.com/watch?v=NLd49pbd8WE&t=3s

Projected Revenue
https://whattomine.com/coins/151-eth-ethash?utf8=%E2%9C%93&hr=7200.0&p=19552&fee=1.0&cost=0.1&hcost=0.0&commit=Calculate

I want to start off by saying I absolutely love GPU mining and computer hardware. I'm a massive hardware tinkerer. For me Cryptocurrency mining was a fun, passionate way, to play with Graphics card, overclock, Achieve the best W/H ratio. I had come up with the plan for a 1 year(or less ROI) based off Ethereum price predictions and my ability to keep operating expenditures fairly low. I ran everything out of a garage of a house I bought on foreclosure. My friend, who was mining at the time, help setup the infrastructure to run it. He eventually wanted out and I bought his equipment. The total investment for GPUs was $20,000. Infrastructure was paid for and already in place by my previous mining in 2018. This was a consolidation and expansion.

I had a rough go of it. Some my expectations, such as using Claymore's STRAP features were not working. I had to BIOs mod the cards. However i was only achieving very low hash-rates of 27mh/s and lots of crashes/errors. It wasn't until I find the right BIOs mod that these cards came to life! I was able to achieve around 29-31Mh/s per card @ 120w per card. I did suffer some equipment failures and headaches. I had at least 2 or 3 Asrock H110 PRO BTC+ board totally die on me. Riser failures and even a few RX470's that died. The hardest part was I running everything by myself. If a miner crashed or we had a power outage I'd have to be the one to resolve it or get it back online. This wore on me a lot as I was working, trying to get out have a life, and date.

Sadly, by Dec of 2019 I decided to end my mining farm and sell everything off, including the foreclosed home. I was going to a rough break-up with a girl I was head-over heels for along with other personal issues(depression) that I just wanted to leave my city/state and pursue a new life. Everything was sold off, including the house, and i was set to leave. Obviously life events(Corona virus) have now forced me to stay where I'm living. On the positive note I did meet another girl and made some new friends, but sadly my one big passion, GPU mining is now gone.

So the question is Did I ROI?

Mining Farm Income
https://docs.google.com/spreadsheets/d/17mI2r4EJfb-VmEXN_XizkScRClhrt9CtQGm066RXsNs/edit?usp=sharing

I kept track of my income and how much ETH was sold to cover operating Expenses. In total for 2019 I mined 80 Ethereum, with 32 being sold to cover expenses. Leaving me with 48 Ethereum cleared. At present time ($245) Worth $11,760. If I sold during the last ATH of $290 in 2020, worth about $13920.

So I would have been half-way to ROI since the re-start of my mining farm. Sadly while even selling the equipment I didn't get my full investment back. The Unfortunate news for myself is that I had a NEXO Crypto-backed Loan (How I used to purchase equipment). I had put Whatever ETH I've mined into that loan to keep the LTV high enough to not get liquidated. But during the market flash crash of March 2020, all my Ethereum(Both bought and Mined a total of 170 ETH) was Liquidated to cover my loan (20,000~)

We all face failures, I'm not looking at that, But I wanted to say that by all accounts the farm would ROI by now(even with crash if I had continued to HODL Eth and keep mining), Proving that GPU mining farms can survive. The 4GB limit would of been reached this year but I would profitable by then and selling off the RX470's to ebay, then retooling to other GPUs(1660 SUPERs) or switching them to mine RVN's KAWPOW, would continued life for them.
3  Alternate cryptocurrencies / Mining (Altcoins) / Octominer 8-GPU + Nv 2000 RTX series not working. Seeking help. on: May 18, 2020, 12:50:33 AM
Hey, all

So i purchased a couple Octominer 8-GPU mining motherboard/cases for my friend who wants to get into mining. I figure using some RTX2060/2070/2080's would be no problem. However after receiving the units, it turns out these motherboard do not seem to support the latest Nvidia GPUs(for whatever reason?). Whenever HiveOS or Has8her OS is loaded GPU is there but not working/detected. I've exhausted all other options. Only found one thread on another person trying 1660's with no luck on these units.

Wondering if anyone out there has an updated BIOs for these? Trying to use the Octominer Web contacting support just sits there and spins after I hit the submit button.
4  Alternate cryptocurrencies / Mining (Altcoins) / My stance on Ethereum, ProgPoW, and the ASIC Question. on: March 10, 2020, 01:27:08 AM
Hello all,

This is purely a reach out to the GPU community as a whole and my own personal experience and opinions.

https://medium.com/@infantry1337/my-stance-on-ethereum-progpow-and-the-asic-question-99310d192fb4?source=friends_link&sk=caa693854579225fa90b5e98faa3d77f
5  Alternate cryptocurrencies / Mining (Altcoins) / I Bought 150+ GPUs for Ethereum mining. Think I'm Insane? on: June 12, 2019, 05:46:12 PM
My mining farm has been in operation in various sizes since mid-2017. I sold off most of my GPU during the end of 2018/2019 reinvesting that money into Crypto(Ethereum/BTC) when it was at it low points of ($100/$3800). I doubled my money with the recent bull run and now I recently acquired 104 RX 470 4GB Nitro+ with a plan on acquiring 52 more for cheap(total of 156). I also purchased 38 P104-100s MSI/Colorful(24 pictured rest are enroute). In addition, I have 13 GTX 1660ti's, while my friend has 20(hosting it for him). Total GPU account will be over 200+ GPUs. Thinking about Documenting my recent mining journey now with these RX470s 4Gbs/P104s. Mind you all I got them all cheaper than usually find. RX470 4GBs for $53 and the P104-100s for $180


Plan for the RX470 4Gbs is 13 GPU Rigs on Windows 10 running Claymore 14.6 soft-modding the timings with as low as power as I can get. Preliminary testing shows each card can get about 30.9mh/s @ 110w~(test with motherboard + CPU/GPU/RAM/SSD/PSU was 145w total from wall). Electric rate is .010c/Kw. The P104-100s with Claymore's new straps allows me to do 43mh/s @ 125w per card. Overall I'm positive about getting back in big time!



Edit: For those interested. Per WTT as of today(June 12 2019)

30.9Mh/s per GPU x 156 RX470s = 4820Mh/s (110w per GPU) 17160w *Estimated*

43Mh/s per GPU x 38 P104-100s = 1634Mh/s (125w per GPU) 4750w *Estimated*

Ethereum combined hashrate = 6454 @ 21910w @.10c/kw *Estimated* = 50K Revenue yearly 31K Income with current prices and difficulty. (YMMV)


ROI time of approx 6 Months(just for the purchase the GPUs). Obviously, this can increase or decrease based on crypto markets price and difficulty.

@Voskcoin you should come down sometime brother! Cheesy

UPDATE June 26/2019
https://ethermine.org/miners/531E893595875098c10994dF91edF6D886aF6B63/dashboard

The build is up to 3.5Gh/s(Effective 3.7Gh/s Reported). Still in the working out bug phase. I've never had RX470 4GBs before so it's a learning curve with them and there OCs.

Claymore STRAP feature which I was so hoping for to work, has failed for me, as I cannot get all 13 GPUs to run without it crashing. So the 31Mh~ is out the door and currently, I have them BIOs modded with RXBOOST for about 29-29.5mh/s at 75w a GPU(117w~ real). I've reached out to Claymore and he is helping me with this issue, which I greatly appreciate!





UPDATE BUILD IN PROGRESS!




The goods, with more on the way!
6  Alternate cryptocurrencies / Mining (Altcoins) / Seeking help/info best BIOs(or AMDMemtweak) for Sapphire RX470 NITRO+ on: June 06, 2019, 08:10:03 PM
RX470 NITRO+ (Hynix/Samsung/Elpida)

Wondering if anyone has good BIOs or tweaks for these GPUs? They've been around a while and pretty popular among miners but I'm just getting a batch of them for the very first time. The interesting thing is the AMDMemTweak tool now, I've gotten some idea's for timings but wondering if anyone with this specific card has good timings they care to share at all?


Also appreciate any hints, tips, or tricks (clock/mem speed and voltages) for these cards if other miners are running them currently.



thanks all.
7  Alternate cryptocurrencies / Mining (Altcoins) / Comprehensive benchmark of Ethereum ProgPoW! RX series/NV series tested on: March 28, 2019, 11:19:42 AM
If any of you are following ProgPoW is going to be the new PoW algo for Ethereum. I did a full suite of benchmarks with AMD and Nvidia GPUs to see how it would perform and a break-down analysis!
https://medium.com/@infantry1337/comprehensive-progpow-benchmark-715126798476?source=friends_link&sk=8acbe3fb45ef704a20dc09c87a5890a8

8  Alternate cryptocurrencies / Mining (Altcoins) / Benchmarked ProgPoW with different GPUs AMD/Nvidia on: February 20, 2019, 04:45:20 PM
Figured I post this here to get some more exposure to the general mining community. I went ahead and benched progpow ethereum with some AMD and Nvidia GPUs I had on hand. it wasn't extensive but gives a decent idea of performance to expect.

9  Alternate cryptocurrencies / Mining (Altcoins) / ETH ProgPOW coming soon on: January 03, 2019, 12:58:37 PM
Update: ETH Dev Meeting (around 1 hour)
https://www.youtube.com/watch?v=iSc3TbjZu1k

The Go-ahead has been given for ProgPOW(barring any major problems) Time-line looks to be 3 months~ or next quarter to fully implement ProgPOW.

https://github.com/ethereum/pm/issues/66



First the good news,

Peter Pratscher-"As the gangnam ProgPoW testnet is running smoothly since a few weeks & the mining ecosystem is maturing (open source implementations for cuda & opencl are more or less done, claymore (the dev of the most widely used closed source gpu ethash miner) has also confirmed to add ProgPoW support to his miner) I think it would be a good time to finalize the discussion if Ethereum should switch to ProgPoW during the next core dev call?"



Claymore is creating ProgPOW miner for ETH-hash.



ProgPOW WILL be coming to Ethereum. It's just a matter of when?



Bad news-

Discussion will have to take place to decided "When" to include it, either on the current release cycle of 8 months or Ad-hoc. It's unlikely that ProgPOW will be included in next HF, but they're may be an Ad-hoc HF that would include it. As they have stated Earlier that ProgPow and Constantinople are not complimentary and could be achieved successfully separately. I hold out hope.


@PheonixMiner team will you be supporting ProgPOW, How about other Devs such as T-rex/Cryptodrege etc?
10  Alternate cryptocurrencies / Mining (Altcoins) / Testing x22i Algorithm on: November 18, 2018, 03:27:17 AM
Since we are in a bear market and continue going down (https://www.youtube.com/watch?v=IjQkgZmBjzE) I decided to undertake to check out SUQA, or x22i Algo. What's the best Performance/Watt/Miner for it?

The test was done with 8x GTX EVGA 1070SC at various power settings. Wattage was taken "From wall" includes CPU/MOBO/RAM/SSD power. Windows 10 was used with 416.34 Nvidia drivers.

11  Alternate cryptocurrencies / Mining (Altcoins) / Testing PROGPOW with AMD RX580 8GB and GTX 1060 3GB. My findings on: November 05, 2018, 04:27:47 AM
In case anyone was interested if ETH does change algo going to ProgPOW I did some testing with cards I had on hand and probably what most gamers/miners use Mid-range GPUs. Even a low-end GPU I had on hand for fun! Here's what I noticed

RX580's Min of 8.5-9mh/s~ max of 10.4~ Huge increase in power, lowest I saw was 160w - Highest 220w!
GTX 1060 GB 5.8-6mh/s~ max of 7mh/s Lowest power was 85w highest was 140w
RX 460 3.1mh/s minor .01mh/s changes in overclocking mem/core or modding BIOs
RX 460 (unlocked shaders) 3.5mh/s again no changes when overclocking, netting .4mh/s increase with more shaders.

RX580's did not see any improvements when solely overclocking the memory, all the way up to 2300mhz memory OC. Only started to see improvements in hashrate when overclocking the core from 1200 up to 1400. However, power consumption was insane at 1400core 1150mv used 220w GPU+Riser!

GTX 1060 3GB seems hampered by its 192 bit-bus GTX 1060 6GB might net a slightly high hashrate because of the extra shaders but the "GTX 1060ti" with GDDR5X might actually do well. Going from 100% power to 75% power saw very minor differences in hashrate. Only saw a major drop when I hit around 60% power. 65% power + core overclock seemed to be the "sweet spot"

RX 460 only saw an increase with increasing the shaders and saw no improvement when OCing memory just like RX 580. Seems the 128bit-bus hampers greatly. PROGPOW requires high-bus such as HBM and many shaders. Core speed only counts when it's very low, shader count seems more important.

TLDR;
RX 580 increases in power + 50%
GTX1060 1.2mh/s difference in speed between 100% power and 60%
RX 460 unlocked shader helped increase hashrate. Overclocking the GPU did nothing.

12  Alternate cryptocurrencies / Mining (Altcoins) / Good bye Antminer Z9(equihash ASICS) on: October 31, 2018, 02:45:57 AM
Zcash announced they will change mining algo in late 2019. While people could still ROI there Z9 ASICs within that timeframe(not if this bear market keeps crashing!) Everyone who decides to keep is basically left with doorstops, leaving only HORIZEN(Maybe?) and few other small Equihash coins.  Roll Eyes

What're everyone's thoughts? Is Zooko insane for waiting a year to change it? how will that affect the network considering it will be fully dominated by ASICs then?

13  Alternate cryptocurrencies / Mining (Altcoins) / Strange Issue with Z9-mini on: October 05, 2018, 09:00:32 PM
Hey all,

I currently run a few Z-9 Mini's and sometime during the early morning 5AM or so they all Ramped up in fan speed (so very noise woke me up) I checked and they all stopped hashing. I shut them down, but when i restarted them they would just endlessly reboot(Fans' ramping up/down continually). I remoted in via IP and saw they were not getting any network connection. Checked all my network settings, My personal computer/phone could reach out fine, but any of the Ant-miners could not using the PING built into them. I unplugged my Modem, Router, and switch. Plugged them back in and still couldnt get them to hash.

Having messed with them for an hour I had to leave to work. I shut them all down. I come home now, turn them all back on and POOF they all work and are running normal again. What the hell happened?

Heat?
They are in an Airconditioned Room that's always at 70F, board temps I never have seen more than 65C(Temp Chip) on a hashing board.

Overclock?
I Do have them overclocked but they've been running fine for over 2-3 weeks before this happened without any crashes or serve loss of hashrate.

Network?
I unplugged my Modem, Router, and switch. Plugged them back in and still couldn't get them to hash.

The only error I received was on the mainpage saying

"antminer Hardware Version Socket connect failed: Connection refused"

Mind you this wasn't a single Antminer Z9-mini this was all of them that happened and all at the same time, all had the same error. I'm glad its working now, but I'm stumped as to why it failed.

15  Alternate cryptocurrencies / Mining (Altcoins) / RX 580 incorrect shares /w Anorak BIOs on: February 06, 2018, 01:45:16 PM
Hey guys I was just wondering anyone's experience with RX580's and getting incorrect shares with Claymore's dual miner? I'm only having this issue with my AMD rigs. My one GTX1070, 10 GPU rig overclocked fairly high has zero incorrect shares


I have 2, XFX RX580 4GB and 2 MSI RX580 8GB rigs. H110 Pro BTC/3930/4GB RAM/2400w Server PSU + 650w EVGA Platinum PSU/on SMOS.

The XFX 580's 4GB GTS I've Modded the BIOs using Anorak's powersave bios, but seems every GPU is throwing incorrect shares at least 1, same with the MSI RX580 i've modded using another BIOs I found. This is at stock or OC clocks, XFX 580 1100/1800mhz clocks/ MSI 580 1125/2000mhz clocks. It's currently very cold so heat isn't an issue I have them in My garage and they sit 65C(holding temp).

Right now I'm chalking it up to bad BIOs mod timings, but considering how bad the XFX 580's are doing using Anoraks powersave bio's I would of assume these have been vetted over and over, but still get incorrect shares at bare minimum overclocks.


Now they all run stable and will run for days with stock or decent overclocks just quite a few incorrect shares. From what I've read you wanna keep incorrect shares to zero. What's your guys experience?

Any one else have RX580 with micron memory, seems to be the best to me. Best timings out of box, best overclocking, kicks samsung to the curb.
17  Alternate cryptocurrencies / Mining (Altcoins) / RX580 How to get lower wattage? (via BIOs) on: December 01, 2017, 06:50:11 PM
I've been playin around with my XFX RX580 GTS XXX 4GB (Elipda/Hynix) I'm able to do about 166w Dual mine ETH/DCR 29mh/s-870DCR. I'd ideally like to get that wattage lower what is everyone else doing to get lower watts?

Here what I've tried
Modded BIOs using Anroak power save. As a starting point.

Changed TDP limit to 105, max to 115.
Core clock to 850mv, Memory 960mv
1130 Core. 2050 memory.

ETH only I pull about 136~ watt
ETH+DCR pull 166

I'm using windows to flash and SMOS for testing. In SMOS I tried both not using the OC tool built it, and using the OC tool with 1130/2050/ and tried different PS 2/3/6


So far I have some fluctuations for 1-2 GPUs going down to 25 Hh/s and bouncing so I assume these are unstable, but when I disabled them in claymore, a different GPU would then start bouncing around.   

I've seen youtube others pull about 121w per card for ETH only using MSI RX580 8Gbs. How is he achieving this? What are you guys achieving?
