It's so lonely out here. - https://www.youtube.com/watch?v=9_mv1pd3BIA

Is anyone else on this? I'm using nvOC, 13x 1080ti, 6x p106, 8gb ram, g2620 CPU. Mining equihash at 11000 sol/s.

I can't get any ccminers to work, they all throw up cuda errors or crash immediately upon launch. So I'm missing out on vertcoin which is a bummer. Claymore dual and eth only works though, but sticking to equihash now as it's most profitable. My odd numbered cards get about 720 sol/s and my even numbered cards are 700 sol/s or below. Have no idea why. Thinking it has to do with the motherboard. Do we expect a future bios update to unlock the 13x limit? When?

Who else is on this? What are you mining?

Mobo is all set and waiting for 19 x P106-100 6GB, ETA 2 weeks. Should work right ?

definitely. keep in mind I think my p106 speeds are quite low though from what I hear other people get. not sure if it's the mobo

Right, What gen speed you running on ? Mind sharing your clocks on these p106 ?

Nice rig. But those efficiencies are pretty bad. Is electricity cheap where you are from?

Not yet a 19-GPU ASUS B250 user but with my 12-GPU rig i make sure all efficiencies are above 3.0.
It should be easy to undervolt NVIDIA cards as they can easily be tweaked using afterburner.

Watt for an impressive setup !
But, unfornately the ~2.40/2.50 sol/Watt ratio is very bad.
Even with my old GTX750 (non "TI"), from the previous nVidia generation (2.5 years old), made a better ratio (2.56 sol/W).

maybe use 3 power 1600w

I'm using the rig to warm my apartment, so I really don't care about the efficiency, just need it warm in here. But I will play with the power limit and overall profitability soon. I have three PSUs and one wattmeter so I really can't accurately measure stuff at the moment.

Hehe I just disconnected my baseboard to connect my PDU on that nice 30A 240V breaker to heat my place too.

I believe 19GPUs will run at approx 1900W so there's no way a regular 15A 120V can handle it. Buyers beware !

Your setup is really impressive. Btw I'm just curious that why hashrate of P106 is almost at optimum while 1080Ti did not get that high.

If anyone can help me get my 1080ti hash rates up, that would be great. It's weird that every other one is low.

Which sites sell the p106 mining gpu's? I just normally shop for gaming based cards

The number of cards limit is not the motherboard, it is a DRIVERS limit.

 I think I remember seeing at least one of the P106 mining cards listed on NewEgg, and Amazon should have sources for most or all of them.

 You might need more CPU or more RAM to run that many cards on one motherboard.

Do you think there will ever be a time when this will work without mining cards?

There is no reason for it to NEED mining-specific cards to run 19 cards.
Just tons of power connections, risers, etc.

 720 is kinda low for a 1080 ti at 100% tdp, unless perhaps they are FE cards (which have relatively poor cooling solutions and don't boost as high as pretty much any aftermarket cards do).
 I get that much out of my Aorus cards at 200 watts (80% TDP) +100 core +100 memory and very close on my Gigabyte Windforce and EVGA SC cards at the same settings.
 Which 1080ti cards do you have?
 Have you done any setting testing on core clock and memory clock on them?

Got them running around 666 sol/s or 10200 sol/s total now as I dropped the powerlimits to reduce heat and noise. I have mostly founder's editions as well as a few gigabyte gaming OCs, 2 gigabyte turbos and two pny 1080ti blowers. Overclocks don't really have so much affect on hashrate with equihash I believe, but everything is running at 150+ core and 450+ memory.

Did you achieve 3.5 to 4 sol/J?

 Equihash can be wierdly picky about overclocks, sometimes MORE overclock gives less hashrate.
 It doesn't seem to be super picky about memory clocks though.

 My GTX 1080 ti Aorus pulls 620 sol/s at 150 watts (60% tdp) for a bit over 4.0 efficiency - which seems to be it's most efficient point or very close to it's most efficient point.
 GTX 1070 ti (I got my EVGA SC today) at 60% can manage quite a bit better than 4 - more like 4.4 - at +200 core +700 memory in afterburner (but the card UNDERCLOCKS the memory by default a little for some reason).

 Up side of the 1080 ti though is rig density and fewer cards to deal with, even if it IS a little less efficient than some of the alternatives.

Hi QuintLeo,

Would you mind sharing what are your core&mem overclock settings for the GTX 1080 ti Aorus 620 sol/s at 150 watts (60% tdp)? That s pretty good number you 've got there.

Is there anyone out there using this board? What are you mining?

 +100 core +100 memory.

 I suspect any of the "2.5 slot wide" 1080 ti models will match that VERY closely, as they all seem to have near-identical factory overclocks and equally overkill cooling.

My long awaited 19 x P106-100 just landed at my place. Will start building soon. Can't wait to boot that mobo !

 My long term intent is to build up to probably 17 cards (1070 ti), but using 3 850 watt power supplies split between 2 circuits and running the cards in their "high efficiency" range at 100-110 watts per card.
 2 x 6 running by themselves on each of 2 PS, then 5 + MB/RAM/HD on a third - though I might go with a 1250/1300 (I've got some X1250 Seasonic and 1300 EVGA G2 not in use) to power 7 cards, that PS would be on it's own circuit that would probably have a box fan and monitor and nothing else.

21 x P106-100 :)

Gotta play with AsusTweakII now.

Where are you guys finding the P106s? Alibaba?

Adding my second PSU this weekend. I can just plug it in straight to the Motherboard right? I dont need to get the add2PSU connector right?

I will finally have the power now to maximize the board, now I just need to keep accumulating cards as I ROI them to get the board all filled up.

Yes, these 3 x 24pin are just a daisy chain.

Are you able to mine anything besides equihash on 20 cards?

Very impressive s3c70r! Could you share a bit about CPU, RAM, have you used virtual RAM, or any special requirement for your 21 GPUs setting?

Thanks!

21 cards and yes, ethash is fine too. Didn't tried other mining softwares beside claymore dual and ewbf/dstm.

But as long the software is fine with 21 GPUs everything is good.

i3-7100, 8GB Ram, 32GB virtual RAM.

Cheapest PCIE 1 to 4 extender from aliexpress.

Stable so far.

Thank you very much!
I will take a try again as I get enough GPUs.

seems like windows can handle over 8+ GPUs, is that win 10 ? how about the updates and drivers ? the last one ?

By the way,
I have been in touch with Asus Technical Support just yesterday and here is the summary to those who are interested:
1) on Asus official website it is mentioned that "An unlimited number of GPUs will be supported following a driver update that is planned for Q4 2017"
https://www.asus.com/us/Motherboards/B250-MINING-EXPERT/
2) Although it is clearly mentioned that unlimited # of GPUs will be supported this year, the technical support could NOT confirm such info, so basically they are clueless whether this will actually happen this year or not
3) At the moment, you can run a maximum of 13 AMD GPUs without facing great challenges. However, officially it is not recommended to exceed 11 AMD GPUs
4) There is one official thread from Asus where they propose different set-ups, so yes, if you max on 13 AMD GPUs, the Mobo will look for P106 mining specific GPUs to complement the 19
https://www.asus.com/us/support/FAQ/1034921

It is very interesting what do you guys think about this Mobo
From one hand, we all know that AMD is the king in mining:
1) it has got better hashrate for every dollar invested
2) yes i hear about electricity efficiency of the Nvidia cards, but if you make your calculations you will find out that 5,000$ invested on AMD cards will net more $$$ than if they were invested on Nvidia cards, regardless of the coin you mine and regardless of the cost of electricity at your location. if you think otherwise, send me your #s and i will be very happy to revise them, i am pretty sure you must have missed something
3) If we can max only 13 GPUs on this Mobo or officially 11, then do we really need 19 slots? assuming that you really want to get the best out of your invested $$?
4) Has any of you challenged Asus on this limitation of 11 AMD GPUs? has anyone got further info when this limit will be eliminated?

Thank you!

AMD is only the king of mining on some algorithms, on others NVidia blows them out of the water, and there are a few it can be fairly close now that the RX "good mining" AMD card pricing is finally getting back down to reasonable.

 Don't ASSUME that ETH is the only thing out there like way too many clueless website reviews, even if it does have more GPUs mining it than any other algorithm.

Could you please give me a concrete example of one single coin and one single Nvidia card?
I want to make my own calculations and show you that investing the same amount of USD you will have higher returns by using the AMD card rather than the Nvidia
Please do NOT confuse me here, i am not trying to annoy you or anyone else
I am trying to benefit myself and others viewing this thread
I am be missing some info and i am very happy to learn from you
However, if Nvidia is able to blow up AMD on a particular Algo, the question remains how much does that Nvidia card cost, and how much does it net at the end of the day, then you will have the net return per dollar invested
For example if Nvidia nets 3 dollars a day but costs 900$, this means that each dollar invested returns 0.0033
However, if AMD costs only 400$ and returns only 2$ instead of 3$, this means that each dollar invested returns 0.005 which is obviously higher than Nvidia

So please give me a specific card and a specific currency and i would like to make my own calculations and come back to you...

 ZEC. Compare against any of the Nvidia cards in the GTX 1070 to GTX 1080 ti range - on both "power efficient" and on "max hashrate".

 AMD cards are ALMOST getting competative there again - but even with RX 570 cards in the $209 range they still have a bit to go to manage it.

 To be fair, go ahead and include the "return" figures for the AMD card doing ETH vs the NVidia card doing ZEC, as that is probably going to be the "best option" for each card.

 Don't forget to factor in SYSTEM COST - the AMD card might be half the price, but you also need to add in the "cost per slot" of the system itself on each side, which will be the same.

 It's a more fair comparison to compare a common 6 card RIG of each card involved, since cards don't mine by themselves.

 

Thank you QuintLeo for the insight, so here are the #s for all of us to review, critisize and learn what is the most profitable GPU\Coin to mine for x amount of $ invested:
Pre-assumptions:
1) Since we assume that we will build two SIMILAR rigs, each accommodating 8 GPUs, this means that the common expenses of each GPU will be the same, meaning that one Nvidia GPU will need for example extra 10$ to be functionally mining and the same goes for one AMD GPU. Therefore, this will leave us focused on the cost of the GPU, Electricity draw, and $s generated at the end of the day\week\month
2)  Lets assume that the cost of electricity is 0.11$ per K\W. If it is a bit different this will affect both cards and not one of them

Lets start with the Nvidia cards:
1) ASUS Dual GeForce GTX 1070 OC, DUAL-GTX1070-O8G
This card costs 406 EUR in Europe, this is the lowest price possible here for this card
The hash rates ranges from 420 to 480, so I picked up somewhere in the middle 450
Power draw ranges from 120 to 140, so I left it at 120 K\W
The results are 2.62$ net profit per day
If we divide 2.62$ by 406 EUR we get  0.0065$ return on each invested EUR

Now lets compare this with AMD RX 580 card:
1) AMD Sapphire RX 580 Nitro Video Card + 8GB
This card costs only 291 EUR here in Europe
The hash rate can get easily stable at 29 MH/s mining ETH
It can also dual mine DCR at 900 MH\s without impacting the hashrate of ETH
This will draw below 130 W, but to be on the safe side I use 130 W
The result is 2.48$ a day (net)
2.48$ divided by 291 EUR initial cost of GPU, will leave us with 0.0085 $ return on each invested EUR
0.0085 - 0.0065 = 0.002
0.002 divided by 0.0065 is 31% higher return from AMD compared to Nvidia

Please correct any mistakes i have made in the above calculations, also please feel free to correct them and present your own calculations, i will be very glad to point out  what i think you have missed from AMD side

Sorry for the long post, but it had to be this way, if we are going to dig into deep details
I hope that this benefits everyone...

 You did NOT take the total system cost into account.
 Try adding $40-$50 to the price of each card THEN compare - and that's being optimistic as I don't think you can build a viable *8 slot* system for $320. It's hard enough building a viable *6 slot* system for $320, if at all possible.
 
 Dual mine of DCR does in fact impact ETH hashrate - that's been WIDELY reported on the Claymore dual mining thread - though it's not a big impact, 10-20% per most of the reports.


 I do agree that relative profitability can vary - ETH in the last week has kicked up a lot more than ZEC has as a percentage, which is giving a bigger boost to ETH mining than to ZEC mining which is at least for the short term boosting the profits on AMD cards more than NVidia cards, at least 'till folks start building enough rigs to drive the diff up to match the price increase.


 It would have been interesting to see how the numbers compared a month ago, when both ETH and ZEC were a lot lower priced and fairly CLOSE on price (and both had a bit less network hashrate).

Anyone using this with simplemining?  Everytime it reboots it hangs :/

By the way, the figures i reported for AMD are quite conservative, and definitely include the slight impact of dual mining
So here i am going to add 50$ on top of each card:
1) ASUS Dual GeForce GTX 1070 OC, DUAL-GTX1070-O8G
This card costs 406 EUR in Europe, this is the lowest price possible here for this card
The hash rates ranges from 420 to 480, so I picked up somewhere in the middle 450
Power draw ranges from 120 to 140, so I left it at 120 K\W
The results are 2.62$ net profit per day
If we divide 2.62$ by 456 EUR we get  0.0057$ return on each invested EUR

Now lets compare this with AMD RX 580 card:
1) AMD Sapphire RX 580 Nitro Video Card + 8GB
This card costs only 291 EUR here in Europe
The hash rate can get easily stable at 29 MH/s mining ETH
It can also dual mine DCR at 900 MH\s without impacting the hashrate of ETH
This will draw below 130 W, but to be on the safe side I use 130 W
The result is 2.48$ a day (net)
2.48$ divided by 341 EUR initial cost of GPU, will leave us with 0.0073 $ return on each invested EUR
0.0073 - 0.0057 = 0.0016
0.0016 divided by 0.0057 is 21.5% higher return from AMD compared to Nvidia

by the way, if we switch to 13 GPU Mobos we can dramatically reduce the common fixed costs, but as you can see over 20% is still to the side of AMD, which is not little at all
I have been doing such comparisons for the last two months, and i NEVER managed to find an Nvidia card outperforming AMD card, specially if we focus only on the 8GB and above, because anything bellow this could easily become useless within a year, specially the 4GB versions (depending on the currency you mine of course)

Once again, this makes me REALLY very puzzled why would anyone invest on Nvidia cards from PURE financial perspective? I see people building an entire farm of up to 100 1080 TI GPUs, and i wonder if they invested the same amount of money on AMD 580 would they have made more money? All #s indicate that they should make much more on the 580s. So why would someone invest over 100K$ for less ROI?

This makes me feel that i am missing something here
what is it?

Your over complicating it and counting peanuts.  I have no problems ROI my nvidia rigs at 6 months max in real life practice, Pick the coins you like and mine them with whatever hardware does the best at it. simple as that

Yes. not any problems. I have a similar system working well.

One factor to keep in mind - ETH mining GOES AWAY sometime, when ETH moves to POS - and the last I remember seeing about it is that the "first move" in that direction is due very soon - though that "first move" was supposed to only be 1% into POS the rest still POW, and likely a few months at least before a bigger move towards POS happens.

 I'm also NOT buying "29 Mhash/sec" as a CONSERVATIVE ETH hashrate figure out of any RX 470/489/570/580 card that is dual mining, most of the figures I've seen reported were "27-29 SINGLE MINING" at best and 26-27 when dual-mining on that series of card - but that WOULD still leave AMD ahead at this point in the comparison.


 The main reason I moved to building NVidia rigs around the start of this year was to "dual fold" CureCoin and FoldingCoin - and for a lot of the last 8 months that combo was returning 50-100% better returns than ZEC - but the ability to SOAK more hashrate was so low I avoided talking about it at all.
 It was NICE seeing $8-$10 a DAY out of a single 1080, and some days hitting $15 on a 1080 ti for a brief while at the peak profitability about 4 months back - but then several other folks decided to jump in BIG time and profitability started dropping.
 At one point my "fairly small" farm was producing about 3% of the entire CureCoin team production - by the time I gave up I was stuggling to stay at 1% with TWICE AS MANY CARDS (and more high-end cards as a percentage).

 As of right now, my most recent calculation shows that "dual folding" is little if any more profitable than ZEC, at least in part due to abuse of a big commercial "render farm" one of the primary CureCoins developers has been using to deliberately depress earnings (and who has ticked me off with his MISUSE of his developer position to the point I refuse to have anything to do with Curecoin at all).


 I'm a bit shocked you didn't bring up Vega - though availability of Vega cards is almost NONE the past week (other than the crazy-high priced FE) and the cards that HAVE been available have been high priced enough that the 2000ish XMR hashrate they can achieve doesn't end up giving that high a value on return/investment right now (it WAS very quite high when you could get the Vega 56 for under $500).

Hey guys, sorry if this has already been mentioned somewhere but how do you get more than 8 NVIDIA GPUs to work on Windows 10 ? I've been trying to build a configuration with 12 GTX 1060s using this mobo.

It works perfectly fine with 8 but doesn't get past the ASUS logo which is after the POST - it's not frozen, the loading animation keeps going but nothing happens. Then when I enter repair into safe mode I can see all 9 cards successfully in the device manager but then same thing happens after I restart in normal mode.

Again, this has probably been answered somewhere but I couldn't find after an hour search so I'd really appreciate the help.

yes, me too.. you should turn it off first to make it work again..

How are you getting 21 cards to work on a motherboard that has 19 PCIE slots?  Using some kind of spliter?  If so, what kind?

How long does it take the system to boot? 

Would any you that have gotten 19 or even the elusive 21 cards to work post the products you use in order to get it to work?

I'd love to build a 19 GPU monster, but have been having trouble with trying to get more than 4 GPUs to work on the biostar 12 GPU motherboard.

Thanks.

My friend tell me to update win 10 to fall creator edition.. And b250 can support to 13 gpu.. I will try it too, but the gpu and Mobo still on the way :)

 I think they mentioned using M.2 to PCI-E adapter(s).

 And IMO 19+ cards is for bragging rights only - that's one HUGE loss of income if the machine goes down.

got the same mb
did you read page 1-9 of the USER GUIDE?
there are limits to what you can use and where

i got 8 VEGA 64's running very stable at 43.7MH/s each, mining ETH (i can get some at 45.5 but to much strain), when i add a 9th VEGA, 2 of the GPU's almost half in speed
i think its a PCIe buss issue

ASUS has promised a VGA driver update by the 4th quarter 2017 which is now, so i am patiently waiting and checking for it daily

my bro is running 9 VEGA 64's on the Asrock H110 BTC Pro with no probs (apart from the PCIe ports being stupidly joined together needing shielding between the riser jacks)

nice rig mate, but i swear by the VEGA's even come with a little sneaky bios switch ;)

Driver update should be first released here:
https://www.asus.com/us/Motherboards/B250-MINING-EXPERT/HelpDesk_Download/

Don't insist on running Windows - LINUX supports a lot more cards without having to jump through hoops, and is more stable too.

Does anyone have 19 cards working on anything other than claymore or equihash? I'd love to get neoscrypt or some other algos working, but literally nothing out there supports this number of cards except claymore and ewbf.

I will pay $100 or whatever you want if someone can get me running on NeoScrypt

Did he do anything special to get that to work? Mine simply will not POST with beyond 7 Vegas plugged in.

halp

Awesome miner doesn't work with Linux and not all miners are available for Linux either. I am looking at trying to upgrade a 8 GPU rig to 11 GPUs and eventually 13, but I am getting stuck on how I will be able to overclock on windows using more than 8 GPUS. I want to keep using Awesome miner too. Ideas?

Look up nvOC.

Does anyone think it would be possible to modify the bios on nvidia cards somehow to flash with a mining card bios so you could get around the 13 card limit?

No, another question is if amd mining cards work the same as nvidia p106. Flash amd rx 570 or 470 gpus into mining cards so you could get around the 13 card limit.
