Hey guys I've been working on a 12x 1080 TI Mining rig for about a week hit a couple bumps in the road, its pretty much working properly now
https://www.youtube.com/watch?v=cEPasa6y2rA

Here's my video on it for those interested, guide on how I built it basically and overview.

A couple notes
 2400w Server PSU https://goo.gl/oG3vh6 is powering only the cards now and the EVGA 750w ATX PSU https://goo.gl/Wu5jvu is powering all risers, asrock h110 pro btc+ motherboard and the CPU / Molex slots. Powering ATX / Mobo / Risers then Server PSU/Cards

Screenshot was shown with 100 core 0 mem - now experimenting with best settings its been on 200 watts entire time, currently at 200 core -500 memory but always open to suggestions / mining equihash / ZenCash

For those interested in the parts used I put together a full part list that has everything I used to build this 12 gpu 1080 TI mining rig

Nice guide

I'm about to do a similar build but looking to use this PSU.

https://www.ebay.com.au/itm/Deep-In-The-Mines-2600w-ATX-Power-Supply-180v-240v-ETH-ZEC-mining-S7-S9-12-GPU-/401396653730

Interesting that you'll need only 6xVega56 (950watt) to have the same earnings as your monster 12x1080ti zec rig ))

Show your calc's. There is no way.


OP, it is recommended to power the risers with the SAME psu used to power said gpu.

Interesting and very detail video. But it would like to see the work of the rig. Temperatures, hashrate. You don't use external fans for additional cooling GPUs. Why?

Wow. I really enjoy the videos you post. Always juicy and just what is the dream of every cryptocurrency fanatic. My friend to me you are living the crypto life. Kudos, i envy you.
You've made a follower out of me and i've subscribed to your videos. I can even click on ads for you. Looking forward to more of your videos. Cheers!

Looked your video nice mining rig construction.
Keep the good work.

I was told with my setup it'd be best to power everything aside from the cards with my ATX and then plug the server PSU in to power the cards about 3 seconds after turning on the mobo so that all risers will be on and can sync the cards?

@rednoW What calc leads you to believe that?

Thanks!

I would be all over that PSU if it was higher efficiency, seems PERFECT for this build lol

The PSU you use is a server psu, its powered up at all times, meaning your risers will have constant power. If two supplies power two different things, things can become out of sync.
If two different things are powered from one supply, things can NOT become out of sync.

I am no electrician therefor I wish someone with higher knowledge can confirm this to make you more certain that it is indeed wrongly setup.

Thanks!

Here's a read out of it right this second

This was 200 watts 100 core 0 mem

The structure it's setup in uses ambient air so now that its cold it will be no issue, next summer I may place a fan in front of it and I may put a 120mm fan in front of the server PSU since I'm pulling 100% out of it - constantly trying to improve my rigs and setup but seems like a never ending project . . lol

thanks my friend and thanks for watching :D

haha I'm not living the dream, apparently THE craig grant of bitconnect is . . . . ???

On a serious note I'm just chasing the dream / crypto life . . hoping to go full time into crypto in 2018 so we shall see. Really appreciate that and thank you, means a lot!

Thats pretty awesome. I realized to build a professional business it boils down to only the three essential factors:

* hardware price (Mh/s per $)
* hardware efficiency (Mh/s per kw/h)
* electricity price ($ per kw/h)

I also use the 2400w psu from parallelminer to power my cards on two miners one breakout board for one miner and the other for second I haven't had any issues my rigs been running for months with no down time or crashes when I was running psu's for my 290's I constantly burnt out plugs I'm also going to try out a pico on one and if all is good I'll run all my rigs off server psu's they are meant to run 24/7 the only issue for some people might be that the 2400w run off 220v so if you don't like or no how to play with power that can be a issue other than that I love these

Ahhh.... I saw the video now and make sense now about the power/wiring/synching issues.

Glad you got this going Vosk - congrats!

Those Deltas are very good - all my 12/13/19 GPU rigs are using them with PICO kits.

I have it on order and will be testing it  very soon.  I will run it with  about 1150  watts running 8x 1070's

yeah pretty much :D

when you say plugs you mean pcie plugs?
also I was talking with Joseph @ Parallel Miner the other day and he said that the 2400w supply is running low & that is why the price has gone up because their cost to get them has gone up. So we might need to stock up O_o

yeah xD

haha thanks my friend :D

Yeah I'm really impressed with the 2400w, a ton of power for such a small footprint

on your 12 13 19 gpu rigs, what cards do they consist of and do you use the pico kit from PM?

The big rigs are all ETH rigs (RX470s) but now I have stopped ETH mining.

All of them are selling hash at NH/Cryptonite since 2 months ago.

They will switch to BTG mining together with my NVIDIA farm.

BTG official network is expected to start on Nov 12 2017, 7 PM UTC.

Testing those riserless boards with NVIDIA and Deltas soon - see Phil's thread.

PICO kits I get some from PM, Aliexpress seller and Captminer.

How loud do you find the server PSU? Any louder than an ATX one?

it's potentially louder / depending on how hard you run it / its temp but around 50-80% usage its not very different

if its hot and running max load it is certainly louder than an ATX PSU, my evga are near silent

How is BTG mining? I am looking into it today and going to move a couple rigs over, is it all the rage?! xD

EPIC fail this BTG mining - I would stay away until pools stabilizes - currently very slow confirmation times - I suspect not enough hash to process transactions smoothly.

that's disappointing . . BTG fail after fail lol, hope they get their stuff straight so we can have another big GPU coin to mine

Amazing Guide and video !
Thank You !

Sorry for late answer. Cryptonight-based coins was twice profitable with Vega then 1080ti with lower power consumption. And still are good.

Amazing rig... 12x 1080Ti is sick. Would cost me over £9000 to build that rig in the UK lol... I wish i had a bigger credit card lol Ill just struggle to get my 6x 1060 6GB rig up :P

Hey Vosk, I got a question for you. I am running a somewhat similar rig such as yours, only it is the Zotac 1082 TI's. One question, Have you ever experienced the cards turning off mid mining due to the fans shutting off because of heat?
 
What should I do regarding it? Should I arrange them in a way that increases airflow?

Those things are good but being a good trader and having money  capital and good money management is better. Don't expand too fast where your taking on debt. Hodl till the profits are juicy. that's where the real money is at.

Good electric rates will do you no good if your always selling them right away at a low. Gota let it grow with time

True, issues with ti`s memory type, same as with eth algos. But there are tons of other algos working wonders on ti.

youre welcome I'm glad it could help :D

yeah i've wanted to pickup some vegas but theyre all stupid priced again, they were 400 just a week or so ago but I didn't have the funds ready yet

haha hey man you can always apply for another! 0% apr for X months is a beautiful thing //nothing ventured nothing gained

Post a pic? Whats your frame setup? At a minimum I'd put a fan in front of or behind pushing/pulling the hot air off them and bringing more cool air faster

thanks bullvied I really appreciate that man and thanks again for using my links that really helps me out :D That's awesome I helped get you into mining / I owe it to this forum for helping me to get into mining so I'm glad I can make a semi decent tutorial xD

Any videos you'd like to see me make in the future?

 Cryptonight on Vega is very high profitability right now, if you can get your Vega doing the frequently quoted 1800-2000 hashrate ballpark (this seems to require use of Windows 10 or PERHAPS LINUX, though I wonder how you get the cards to undervolt enough in LINUX to support higher core clocks without overheating or exceeding TDP).
 Forget trying it on Windows 7, even though AMD *CLAIMS* the blockchain driver works on 7 it does not work AT ALL in every attempt I've made to get it working - either constant crashyness on known good hardware, or doesn't recognize the GPUs at all.

 The $399 price point for Vega 56 seems to have been a VERY short lived abberation - 2 or 3 days at most.

I have 2 x 64s (Sapphires) and 2 x 56s (GA) coming next week -- so whats my chances of getting these to work on WIN10 ?

 Good - and at this point that is your ONLY choice for getting high performance out of them, as AMD is being VERY VERY SLOW about getting Vega support working in AMD-GPU Pro for LINUX.

 After much pain and tribulation, I DID finally my 56 to run at high speed on XMR - using Cast as I'm pointing the miner at Nicehash for now and XMR-Stak STILL does not support Nicehash.
 It's a major pain having to "disable" and "enable" the card after EVERY BOOT to get it to do high speeds though, but nothing else I tried out to get it to work right gets the job done.

 Usage of Afterburner vs usage of JunkWattman doesn't seem to matter - neither support undervolt on the blockchain driver, and otherwise they're more or less equal about getting stuff configured (except that Afterburner STILL blows Wattman away on fan control, NO CONTEST, and is just overall easier to use and work with by a TON).

 Sapphire Vega RX 56, not BIOS flashed (though Cast identifies it as having 64 compute units ANYWAY), runs about 1940 hash/s at -10 TDP 940 memclock and core downclocked in Afterburner to 1400 (or -10% core on Junkman).
 Didn't play much with the settings, as it seems like adjusting them CAUSES the hashrate to back down to the under 1400 range every time I tried until the "uninstall/reinstall" trick is done AGAIN.
 I also noticed that adjusting the settings caused the memory clock to reset to 800 Mhz and NOT BE FURTHER ADJUSTABLE a lot of the time - which contributes to the low hashrate issue.

 Not sure how long I'm going to put up with this very unstable BUGGY AS HECK setup, as I have another use I'd like to put the card back to.


 I can verify that Cast doesn't seem to CARE about that "HBCC" setting in Wattman - if I had this whole mess to do over again, I'd install JUST the driver and nothing else in the hopes of eliminating some of the buggyness.

https://vegamining.blogspot.co.uk/  Check this out, it really helped fine tune my rig.

Saw that one and pulled a couple ideas out of it - but can't run Stak as I'm pointing to Nicehash so I have to run Cast.

 Hashrate seems to be pretty similar between the two of them (I think they use the same "core" Wolf0 wrote).

 Someone needs to update a Monero miner so it does NOT need that bloody "blockchain" driver to get good hashrate though - I'm pretty sure most of the changes the Blockchain driver made have been rolled into the most recent "standard" drivers - and that Blockchain driver is buggy unstable junk when you can get it to work at ALL.

Nice work and video! Thank You! ;)

Really nice rig, I only wish my electricity price wasn't so high, would really like to build something like that myself. Keep up the good work!

Ugh this is stressing me out just reading it xD I can definitely feel the anger you've had at these rig(s) lol -- we have all been there!
Whats the other use you'll put it back to and @Citronick have you gotten your cards yet?

QuintLeo has the setup gotten any better? If you've gotten it stable it has to be pretty lucrative

Thanks my friend! What is your electric cost? Maybe it's solar time xD

thanks my friend and thanks for viewing :D

Appreciate it man glad I could help!

What have you decided on to be some of the best bang for buck builds? That's actually a chapter I'm hoping to focus more on soon, I ordered 12x 1060 3b which I'm praying all have samsung memory (pipe dream probably) lol I pulled one out and surprisingly it is samsung but I doubt the other 11 all are

I like the 3 card setups for getting stuff up and running fast, my trio mining rigs have been rock solid since day one but chasing the better efficiency and condensing the parts has been the mission as of late

Thanks again man it's always awesome to get feedback and to know I could help someone out / or entertain

well I read so much about glitches for amd rigs
and I'm terrified  that I have to do all this mamba umba stuff
cause after 10 days I'm gonna receive one vega.. I'll try to install and run it with my 1080ti all together
i hope I gonna make it

 The big issue right now with Vega is that AMD has taken forever to get WORKING drivers available for LINUX - so you had to use Win10 if you wanted to use the Blockchain drivers (needed for high XMR mining rates).

 In THEORY, the 17.40 drivers for LINUX have fixed that - but I've not had the chance to check that out (it's on my agenda for this week) and also include the Blockchain "fixes".

 Given that AMD CLAIMS the 17.30 "Blockchain" drivers are supported for Windows 7 WHEN IN ACTUAL FACT THEY DON'T WORK AT ALL UNDER 7, I am not holding my breath.



 AMD is doing a fairly good job of shooting themselves in the foot with their last 2.5 years of borked LINUX drivers, and their drivers that have been frequently total junk in general.

Already have 5kW solar system and selling absolutely nothing back to the grid. Will have to look into expanding. 20c US /kW. ~18kH/s currently and last electricity bill was ~$1700US per 60 days   :o
Even bought and installed solar+vent combo to save on cooling :D

With THAT kind of an electric bill, you should consider moving to somewhere with lower cost electric.

 20 cent per KWH is prohibitive for long-term mining profits.

 My last bill was $550, and while I was "only" generating 15k-16k sol/s during that month I also had a ton of power feeding the A2 Scrypt farm (MORE than the ZEC farm I think, though it's gotten quite close) + some feeding my DNet/Moo Wrapper/BOINC farm, which includes all of my older powerhog HD7xxx and R9 280x/290 cards (along with some RX 470s and A10 iGPUs), and some feeding the CPUs I have mining Monero on most of the GPU-centric machines.


 Oh yeah - some of it was also going into the 1 Evap cooler I still have running, and a little into the A/C unit that keeps the seperate "office" type space cool.

Nice man ! Good Work there
That rigs is compact and has really high density .
You can earn around 62 dollars from a single rig and thats only if you are mining zcash a stable coin
You can learn a lot more by mining niche coins like zcoin and others , thats like a 100 $ a day , i.e 1860 -3000 dollars minus the  power draw a day
Thats a good amount of money
Anyways would like to ask How much did it cost you in total and what amount are you earning realtime and how much power is it consuming .

haha that sounds like a headache in the making to me O_o how'd you get on with this?

I'm not nearly as experienced with AMD as you are but from everything I see I absolutely agree. . It's why I stick with the green team lol, I've seen some people give up with setting up a Vega rig lol

ah that's tough . . where are you located?

I'm glad you have a solar system setup to help with that, did you setup your system yourself and if so how did that go?

I want to move to washington state to pursue my mining dreams T_T lol

Can you tell me more about why you dedicate those resources to a BOINC farm as opposed to slapping them on crypto?

Thanks brother!

Cost about 10k all cards bought at $700 or less all cards hash ~700 sols

Currently its on suprnova zen which is hard to monitor its exact output as opposed to being on a pool like zhash or luckpool https://zhash.pro/workers/znkPcNtQTKfBkwPqnQBdKRuifeVejrEhjRU where I get read outs for each rig w/ earnings

uses ~2600watts or so haven't measured it

 Most of them are older AMD cards that wouldn't make a lot more doing mining (I've checked it occasionally), but are KILLER on the Distributed.net RC5-72 project (which I have been a participant in for well over a decade, and close to 2 decades working with DNet in general, but moved to working with it via the Moo Wrapper BOINC project a year and a half or so ago to monitize it somewhat via GridCoin).

 When I get tired of the instability of Win 10 as needed to run a Vega on Monero mining, the Vega 56 will be moving back over to Moo Wrapper as well - DNet is one of the few places that the Vega cards are comparable in performance to the GTX 1080 ti (not 1080, 1080 TI that was not a typo).
 I didn't manage to snag a Vega 64 before the prices on ALL the Vega cards got insane, but I suspect a well-tuned Vega RX 64 would be THE highest performance GPU for Dnet/Moo Wrapper work given how close the Vega RX 56 is - with the way overpriced Vega FE being a very close #2.

 The R9 290s, R9 280x, most of the HD 7xxx, and some of the RX 470s DID specifically mine crypto for a while before the big altcoin price/profitability jump, but I'm making enough right now that I don't NEED to squeeze every last penny out of every card I have.

 Turns out that my best current estimate on the "ZEC + Monero" machines is a hair more than the A2 farm is eating - but it's STILL quite close - 5800 watts vs right about 6000.

That's really interesting thanks for sharing, I won't bug you with a ton of questions on it but I'm definitely going to go spend some more time researching this lol. Seems like a very cool project, you think GridCoin will have long-term usability or it will fall off? I imagine you believe in it as you dedicate a nice chunk of machinery to it!

It's not that I "believe in Gridcoin" - I actually think how they have things set up needs a major overhaul.

 It's that I'm a 20(ish) year participant in the Distributed.Net project, and working with DNet through the BOINC Moo Wrapper project instead of running the DNet client directly lets me earn enough coin to pay the electric and sometimes even turn a small profit on doing something I want to do anyway.

Thanks brother!

sorry about the scammer but it's awesome youve got 13 1080 TIs plus those are supposed to be sweet cards! good luck and post some pictures of your build and final numbers!

The way ZEC works, sol/s *IS* hashrate for all practical purposes.

 Yes, that's the number you plug into whattomine or other calculators - always keeping in mind like ANY OTHER algorithm that the calculator can't account for stuff like stales....

happy to hear it man! How did you end up getting on with the rigs?
