Im running 13 GPUs on one B250 ME M/B. (2) 1080, (4) 1060 and (7) 1050 TI. Thats Rig2. Rig1 currently has 9 GPU's. (4) RX 580 (1) RX 570 (1) RX 470 (1) RX 560 (1) 1050TI and (1) 1060. They are stupid easy to setup. Patience and install one card and its driver one at a time. Reboot and verify before shutdown and installing the next GPU. Im running Windows 10 Pro. G3300 CPU (2) 4gb memory 2133 and 120gb ssd.

Wattage does not melt wires or connectors. Get it through your thick skull.

That statement right there clearly proves you havent the slightest clue about what you are talking about when it comes to electricity. Wattage is a direct function of Current and Voltage. The wires in the wall have a resistance and the load attached does as well. (Voltage divided by Resistance equals Current) Kid, you are a freaking rock! Get over yourself, you do not know what the hell you are talking about and are way out of your league. Give it up snowflake.

Unless your basement is a finished one then why would you want to put electronics (GPU's) in a high humidity environment. Unless the basement is air conditioned too then your concrete floors are wicking water out of the ground and it is in the air of your basement. Take a look at any of cooling duct work in the basement in the summer. Where do you think those water droplets come that are on them come from? Its from the humidity. And humidity is 1 of 4 main killers of electronics. The other 3 being dirty power, static electricity and heat.
If you can keep the humidity down to under 10% then you should be ok. I live in the midwest and it sure as heck aint no 60 something degrees in my basement in the summer like someone else mentioned here. Its close to outside ambient temp.
1500w/h of power consumed generates 5100 BTU/hr. That is almost 1/2 ton of cooling to remove the heat that is generated (Not taking a/c efficiency into account). A ton of cooling would be 12000 BTU a/c window unit. Average house has 3-3.5 ton cooling units.(split system with outdoor condenser AKA Central Air)

THis is why you run 220v. Double the voltage, half the amperage, half the heat from resistance and more efficient.
You are wrong. The amperage is split in half because there are 2 hot conductors in 240v wiring instead of there only being one in a 120v feed. You are still using the same amount of power. Watts is Watts. You cant defy ohms law. A 120v circuit drawing 20 amps is 2400w and a 240v circuit drawing 10 amps is still 2400w. Power = E x I (Voltage x current). So you are using the same amount of power no matter which route (120v or 240v) you take. Indeed the amps is halved ON THE POWER CONDUCTORS of a 240v wire feed but that wont help since most houses have 120v feeds so a 240v would have to be installed new and obviously could be sized CORRECTLY to avoid any overheating for constant duty. Go back to school noob. Double the voltage(P), 1/2 the amperage(I) across the same resistance(R). That IS ohms law. Wattage is just a measure of power. Power/wattage does not create heat, resistance does. Half the amperage across a resistance is half the heat. Half the heat = no melted power meter. The fact he's overloading the circuit is another issue entirely. You go back to school amateur before you get someone killed. E=IR is OHMS law, Not P=IR. P=power, E=voltage. Wattage isnt "just a measure a measure of power", It is a direct function of E and I hence the formula P=EI. 10A @ 240v is the same as 20A @ 120v. (Ill bet if you multiply 10x240 and 20x120 they both come out to 2400...Watts) Same 2400w of power. No less power is consumed on one or the other. So just because the the current is halved on a 240v circuit but is doubled on a 120v circuit equivalent doesnt save you on anything other than the size of wire needed to handle the current. The fact that you dont comprehend the fact that watts is watts tells me that you have no idea what you are talking about when it comes to electricity and shouldnt be giving anyone any advice concerning electricity. Its geniuses such as yourself that end up burning their house down or killing someone with bad "knowledge". I was an aviation electrician on the F/A18C Hornet in the US Navy, Electrician & Electronic Technician for Eaton Cutler Hammer, Sub contractor for many large manufacturing facilities and have been a technician for the Federal Aviation Administration for 12 years now as a Journeyman Electrician & Electronic Technician. I take care of a 100kw, 50kw and 37.5Kw standby emergency generator and their switchgear (all 3 phase 208v) among a host of alot more gear that youve never even heard of (VOR Station, MALSR, PAPI and much more). So what do you do when you arent in your parent's basement, kid? "Double the voltage(P), 1/2 the amperage(I) across the same resistance(R)" Really now? If you double the voltage, current goes up by a factor of 2. In this case you would need to manipulate ohms law to solve for I which would be I=E/R. YOU FAIL...Miserably. Yet you still don't understand how doubling the voltage halves the current in this situation. Double the voltage, half the current. Half the current, half the heat. Half the heat, no melted power meter. The only ignorant one here is you. I cant draw it out in crayola for you on here but I guess I can DUMB it down for you. Doesnt matter that the current is halved because the voltage is doubled (120v) In a 240v circuit it would be double the voltage of a 120v. Remember now...Power equals voltage times current. 240v x 10amps is 2400 watts of power The equivalent 120v circuit would be: 120v x 20amps which is still 2400 watts of power. You are an amateur at best and have no business attempting to teach anyone about electricity. Working at a fast food joint doesnt qualify you to be an electrician. Google is your friend. |

The amperage is split in half because there are 2 hot conductors in 240v wiring instead of there only being one in a 120v feed. Strange wiring in your country. I have live, a neutral, and an earth. As the names suggest, only one of them is hot. In european countries and the like you would have that but the math is still the same. Volts x Current equals wattage. |

No matter how many cards this MB can support, it is just a bad mobo when it comes to stability. Take any algo, the hashes will move up and down, never settle. Z270 is so far the best, I have used.
Been running since february. No problems. Me too. Rig2 is loaded to 13 nvidia cards. (wish I coul find some P106 cards at a decent price!) and my Rig1 is at 9 cards and 7 are AMD and 2 Nvidia.(soon to be topped to 13 cards so I have an excuse to build rig3!) |

what version risers? Do you have sata power to riser attached? Work with one card only until you get it resolved then start adding and installing in device manager one at a time after reboot and device manager shows "working properly".

Hello,
I know that I can find out stable OC settings by hand for each GPU by lowering the Memory Clock (Ethereum) after each crash.
But it would be much more comfortable, if a script could doe that automatically.
Like this:
Start with highest settings. After each crash, lower the settings. After 2 weeks without a crash report the max speed.
What do you think about it?
Is there anything like this already available?
what the fuck is wrong with these kiddos nowadays? they want everything ala nicehash. one click and there you go, money printer. Some people just insist on working harder instead of smarter. Kinda like there are those that can and those that teach...because they cant. And how on earth do you know how old the "kiddo" is anyway? Let me guess, you have my age all figured out too? I know how old you are ACTING. Its not the OP's fault that you "cant" so quit being a troll. |

First key is to lower the GPU power consumed (more power equals more heat) and overclock to achieve same or higher profitability using less power which reduces total heat output. Then the key to keeping them cool isair flow! You have to get rid of the heat or you will just be raising the temp inside the home. An a/c unit will remove the heat (thats how it cools a house down) but if your mining rigs makes more heat than the a/c unit removes then the a/c will never be able to keep up with the heat output. Bringing in fresh air from outside is a good and bad idea. When you bring fresh summer air in you are also bringing in humidity which isnt good for any electronics. But even 95 degree F summer air is substantially cooler than what the temps the GPU is running at (75c is 167F!) so it is indeed cooling.

Do you have any idea why your power meter was melted. Basically it could stand for a massive load current.
Good point. I was running a 13-GPU rig mining at a constant 1600 watts. I'm thinking it melted because of wear and tear because it's been mining since December without any problems at all. Where you went wrong is running 1600w through a 15a rated device. 1600w equates to roughly 13.33a that you were running through a power meter that IS NOT RATED FOR 15a continuous duty (AKA 100% duty cycle). I would be more concerned with your circuit breaker wiring connection being burnt, the outlet itself being ruined (I would replace it anyway since you cant inspect the internals) and the wiring in the wall that is also NOT RATED for 15a continuous duty. A 15a circuit and all of its components (Outlet AKA Duplex, Circuit breaker and wiring) are only rated at 80% of 15a which is 12a for CONTINUOUS DUTY! Its called derating and it is a 20% derating factor. A 20a circuit is good for 16a of continuous duty. Upgrade your wiring to a 20a circuit (if it isnt already) before you all burn your home down! |

I now have successfully setup 13 nvidia cards on a B250 Mining Expert Motherboard. There are 7 GTX 1050 TI (4gb), 3 Gtx 1060 (6gb), 1 GTX 1060 (3gb) and 2 GTX 1080 (8gb) GPU's connected and im running EWBF currently.
The only thing that Ive done different is Both power supplies are wyed and only connected to connector A on the MB. I have one EVGA 850w and a Corsair HX750 (gonna put in 2 1000w PSU's eventually). Both GTX 1080 cards are running at 65% TDP and +150 on the cpu and +500 on the memory. This whole setup is yielding 3000+ Sol/s mining ZEC.

still, only 13 non-mining cards with new bios which sucxxs, I am unable to get my hand on any mining cards.
one way to push Asus is to raise support ticket/send feedback and ask for non-mining cards support to run 19 GPUs on this board.
How are you "unable to get mining cards"? They are all over the place. Ebay, Nowinstock, Newegg, Amazon and the list goes on. Did you mean you cant afford them? |

Hi, I'm considering buying about 4 of these units, but ...
How much power has this model in specific?
How long could the investment recover?
In this case the electricity would be 0 in price per hour
I wouldnt buy any new cards right now. The prices are coming down but not fast enough yet. Used market is where its at right now. More bang for your buck. Yes I undertand your point. but of all the video cards that is the only one that has the "real" price for the new gpu without rare alterations in price. Check the price of the new gpu in amazon and ebay, and I would strongly bet that the prices are normal for the entire series 580 Your ROI would be in 2019 IF YOU ARE LUCKY just for one card at the current prices. There is no way I would pay more than $300 for a new RX 580 and thats not even going to happen at todays crypto prices. So if I buy on used market I will pay a max of $250 shipped on the used market. I would wait until the Nvidia new GPU's are released and then maybe you will see a decent drop in new AMD prices. Im not buying ANY GPU's right now because ive found a way to get some for essentially free (But it is at a fairly slow pace). Ive gotten 3 this way so far. One of them is a Sapphire 470 8gb too.  |

I have now successfully managed to get one of my ASUS B250 Mining Expert MB's to but and show "green" and mine successfully with 12 Nvidia cards installed unlike what their owners manual says about mixing nvidia/AMD cards in certain orders. Didnt have to do any tweaks or special drivers or nothing.

i will use nicehash system since today, the question are two:
1) When Transfer me to my BTC wallet from nicehash?
2) i'm ussing a BTC Wallet from HitBTC, this is a good way?
Im mining with 1 RX 470 all day, and 2 RX 470 at night
I would get off of it as soon as you are able to setup your own miners. I was on NiceCrash form Feb this year until 2 days ago. Im done with NiceCrash. They show speeds slower than actual of your GPU mining output. I mysteriously show 60-80 sol\s higher on my blower 1080 when its on EWBF miner vs. NiceCrash. Thats just one of the 23 cards I have. No thanks. NiceCrash can shove it. |

If you know how to handle tools then 3-5 meters of 20x20 T-slot or V-slot aluminum profile plus some screws and brackets, couple hours of work (incl. cutting to size) - and you're all set.
yep; agreed. I have a bunch of aluminum c and L channel stock, and a riveter. I am just too damned lazy and want something with less headache myself  Lazy I can understand, I'm lazy myself, too  But on the other hand paying $180-200 for something that costs $40-50 to make, especially this simple, helps fight laziness If you are paying anything much over $100 then you are paying too much. I just scored another Veddha v3c on ebay for $57 shipped. That puts me to 4 of them and 2 stacked will cover one Asus B250 Mining expert motherboard and 13 GPU's and even more if you can find P106 cards. I'm not paying even $100 as I prefer to assemble my 8 card rigs myself. What kind of man can't handle an angle grinder and a screwdriver? One that does all his own vehicle maintenance from tranny rebuilding, PCM diagnosis, Brakes to engine rebuild along with ALL home maintenance including roofing, HVAC install, repair, maintain and someone that owns 5 acres and has more important things to do than piss around trying to "save" $50. Time is worth money to me. Id rather be fishing or hunting than nickel and diming life to death. Who does all your stuff while you are pissing away time over $50? |
