does anyone knows if there is a way to set fan a little more than 100%? like 110% (a litle faster)?
No 100% is the limit. And honestly if setting the fan speed faster than 75% doesn't do anything then setting it at 100% or 110% won't cool your cards. You basically got a overheating and air flow issue going on. Do you have an open air rig or is this in some enclosed computer case. If its enclosed try and take off the cover. If you got some Crossfire set up then put the desktop facedown so the high air can travel up instead of directly into another GPU. If you really want faster fans then you can always take off the fan shroud and zip tie a few case fans to your GPUs. |

The only thing I can think of is that your motherboard is pretty much sharing some PCIe lanes and why you are getting this issue when you add the 5th GPU. I had some motherboard like this in the past, and wasted so much time trying to figure out what was wrong but basically according to the owners manual there were some shared lanes on the PCIe slots.
Basically you can have 2 PCIe slots but you might only be able to use 1 at a time even if you are using risers and running it at 1x. Go to your motherboards manufacteure website and download the owners manual and see if there are any shared lanes.

I'm totally new to mining.
I'm not really sure, but how does the mining performance look for my computer?
Ryzen 5 1600
16GB RAM 2993mhz
Radeon 5700
I bought it mostly for gaming, but since I don't have time for that anymore, then how effective can it be? What can be improved?
Your Radeon 5700 can make about $2 a day or so. With $0.10 kwh in power its more like $1.80 or so. So you can probably make $50 per month as long as you mine almost 24 hours a day. Your CPU is also very good however I don't mine CPU coins so have no idea. The coin to mine with that CPU would be Monero. RAM doesn't really mean much in mining, can't really mine with your ram. Just make sure to keep your case well ventilated so it doesn't over heat. And disable mining when you are going to play a game. |

You can probably even go to Craiglist in your area and there might be some miner out there that wants to just sell his BTC for cash. Just check your local listings and see what you can find. However keep in mind you can't do 5 figure type of deals this way. Very risky.
If you want to buy that much of crypto then you got no choice but to KYC. This isn't 2012 anymore, most exchanges require KYC due to money laundering. The exchanges that don't they are usually crypto to crypto exchanges and you can't deposit fiat into them.
Or like I suggested before, just go to a bitcoin ATM and call it a day. The fee is high but if BTC keeps going up and up then it won't be an issue.

If you want to be a long term investor then just buy it on your exchange with the high fees and just hold it for a few months...years. The fees won't mean much when it goes up another 50-100% or so.
If you want to day trade then you need to buy BTC once and then just send it to another exchange. There are tons of futures exchange out there with very low fees and there are also many exchanges like Binanace which have low fees also.
Most likely that exchange you are using is geared mostly towards investors and not traders.

Your best bet is just to go to a local Bitcoin ATM and buy some that way. Unless you are buying large amounts the 10% fee that they usually charge is not that much and saves the headache of having to create an account at an exchange and go thru verification process.
You need to understand Credit card and Paypal are easily reversable so don't be surprised that they require verification first. I just don't think it will be possible using those methods. Best bet is cash and go to a Bitcoin ATM and you are set.

Might sound like a basic question but how are you guys building your rigs with that many GPUs? What I've done so far is I built my racks using cheap framing lumber... I just make sure MOBO has some spacing with wood using plastic pieces. No way I'll invest in an aluminium frame at $100... I prefer to keep that money for GPUs. Here are those masterpieces (there are actually two racks there... I just built them so they could be stacked):  I've seen those shelves being used a lot: https://www.amazon.com/Seville-Classics-UltraZinc-Shelving-Wheels/dp/B07CJVL5BK... could have 6 rigs on one shelf. I'm wondering how I could "hang" GPUs on them though. What kind of frame/rack do you suggest? I did the exact same as you, basically took a pen tube and cut it in small pieces and used those as the "spacing" between the wood and motherboard. Don't let the motherboard sit directly on the wood because there is a hot spot in one area, I think its the South or North gate of the motherboard and can get hot, might start a fire. I also was going to use aluminum but they were too expensive, so I got some steel ones however they were crazy heavy and just stuck with wood instead. Had open air wood rigs for years and never any issues. |

currently 26th august 2020 and this trick still working on ethereum rigs.
I did install my r9 290x 4gb as gpu1 (phoenix miner) under Hive Os, plus 4 R9 270x 2gb and they just work fine. I also had to tune it a lil'bit (command lines added -rvram 1, -dagrestart 0, -lidag 3, -eres 0) = this gives almost 108Mh/s ^_^
Screenshot to prove? 2Gb cards cannot load a 3.8 GB big DAG. So you are mining an other coin then ETH. And those old cards has another problem to, speed decrease with every new DAG epoch, so you can not do real 108mh my friend. Well, there actually was a R9 270X which had 4GB of GDDR. I think it was made by Sapphire, so its possible that he can still mine ETH with a 270X and might of just done a typo when he said 2GB. However even if the 4GB actually loaded the DAG, it had other issues with thrashing and while R9 270X mined at 15MH/s back in 2016, I am sure now it would mine probably at 7MH/s or so due to that bug. This is similiar to what happened with the R9 280X GPUs back in 2016, they mined at 22MH/s and later in 2018, they mined at like 12MH/s and no fix was issued. |

The market caps on CMC don't always mean much. One reason is because there could be a small cap coin listed on some unknown exchange with a large market cap while another coin listed on a reputable exchange like Binance can show a much lower market cap. In this scenario market cap doesn't mean anything.
Sure the lower cap coin seems like it might rally much easier however there are more players on Binance than say a smaller unknown exchange. Hence you always need to do your due diligence.

from the killawatt 807watts
nothing to brag about for 5 x 480s at 28.xx mhs
the newer GPUs like single 5700XT can do twice the hash at lower watts
--- snip ---
Software still reporting a total of ~664? Yeah, the 5700xt is basically a double card, lol. Now that I've learned a bit with the dozen Polaris cards I have, I have an appetite for more efficiency going forward. SMOS still reports the same 664w the mobo, ram, cpu etc takes about 142w I can only conclude that the 80ish watts is not correct, since it totals only 408w. it should be 664w div 5 = avg aropund 130ish per GPU, which aint that great for only 28mhs I will keep these 470s,480s aside and offline for now (i have total 240 + 60 of them) All my 1080tis, 1070tis, Vegas are mining ETH for a while now A few 1060 and P106-100 rigs are also just up and running. When ETH goes parabolic, I will squeeze the melons out of the 470,480s - at that time electricty wont be hard to justify. What kind of motherboard and CPU is this? It should take 40 watts or so not 140. If you got some old Quad-core intel CPU then I guess it makes sense. However for most low power celeron processors it seems high. With 5 GPUs of Polaris GPUs your consumption should be ~650 Watts or so. 800 Watts seems high, most likely due to your CPU+Mobo. Are you sure they are all undervolted to 900mV at least? |

You have 2 chains that are not hashing. The ones showing 00 in temp and BB in status.
1st check your power. Could be a bad power supply or one just not putting out enough.
Check the ribbon cables form the controller board to the has boards.
Other than that, there is not much you can do. Boards go bad often, it sucks but not much you can do about it.
-Dave
Pretty much that is it. They had many issues when they came out. Even if you had warranty on them, sometimes it was troublesome getting them warrantied. Hence why I stopped buying Antminers. What you need to do is basically take it apart and check for anything burnt, I am assuming you will find some burn marks on certain hash boards. If there are burn marks see what burnt, if its a capacitor you might get away with replacing it, however chances are the boards are garbage. Don't feel bad, they only had 2 more months of mining left anyways. |

Generally you shouldn't point an air conditioner DIRECTLY on exposed computer parts which is basically what most open air mining rigs are. Reason why is because depending on the humidity some of the water vapors can go on your GPUs and damage them.
However will this be an issue? As long as they are running the water would evaporate almost instantely and not cause damage. However if the rigs crash one day and GPUs are cold and you got a AC pointed at it, you might find it completely wet one day.
This thread however brings back memories. Back in the Litecointalk days, there was a fellow that had so many GPUs that he actually had to use an air conditioner to cool his place..... in the winter. Crazy times.

Well is the stock market manipulated right now? Everyone says that its the bank and large whales that manipulate the price of certain stocks. However right now most people who are driving the market are 18 year olds on robinhood. Remember what happened right after the Hertz bankruptcy?
Someone basically posted they would buy it on wallstreetbets and the next day it kept going up and up and up and eventually it was priced higher than a few days prior to the bankrupty. So is this considered manipulation? There was real demand.
Hence its a term that's thrown around losely and everyone says everything is manipulated.

Yes this is pretty much the reason why many of the DaggerHashimoto coins which got a low DAG got such a low profitability. The reason why is because popular old mining GPUs like the R9 280X or some of the 3GB Nvidia GPUs can no longer mine ETH or ETC so they are mining coins like EXP or MUSIC or whatever is out there.
The same will happen with 4GB cards, they will only be able to mine certain coins which have very low profitability. Hence you are just better off selling them now and get some >6GB models.

Generally all these RX 470/480/570/580 have the same power consumption. If you undervolt to 900mV which is the average voltage before you get stability issues the GPUs pull around 120-130 watts from the wall after Gold PSU inefficiencies and not including the mobo+ram+ssd+fans.
So if you want the best consumption per rig you should use all the max slots on the motherboard. Generally the mobo+ram+ssd+fans use about 30-40 watts and each GPU uses 125 Watts or so. So if you got a 6 GPU rig it typically consumes ~800 Watts or so.
The people that claim that their RX 570 uses 75 watts from the wall clearly don't own a power meter.

RUMOR HAS IT--
Claymore died while trying to jump his Lambo over an opening drawbridge while driving into London.
We are approaching Epoch 384 rapidly. --scryptr
I just think that he is just enjoying his millions and taking time off coding. There are other miners right now that people can use. Maybe if ETH forked to a different algo or if mining was "extremely profitable" again he would start to coding his software again but right now you see how it is. It was profitable about 2 weeks ago, people powered up their rigs and now profits are half of what they were since then assuming average power of $0.10/kwh. He has made extreme profits if he held his ETH and sold when ETH >$1000. His miner was very popular before BTC and ETH broke $1100 and $20 respectivately. Probably traveling the world right now or sailing across the sea on his yacht. |

If I ping "eth-eu1.nanopool.org" from cmd, it is 75 ms but the share acceptance time is 215 ms with same server. Is it okay? Yet, there were no invalid or stale shares, and I am getting around 30 shares per hour for 85 mh/s.
ping will send smaller packet than the share itself. I was mining through VPN for some time with 250ms response time and practically got the same results as with direct connection, so you should be fine with 215ms. Regards, zeezoo You can mine Bitcoin with a large ping such as that but if you are mining any coins with an average block time of ~15 seconds or so you will run into too many stale shares. Generally you are creditted for stale shares however keep in mind that you will make more money overall with a faster ping time. Imagine you and someone else finds a block at the same time, the other guy has a ping of 50ms and yours is 250ms, what will happen is his will get accepted first and their pool will get the credit and not yours and you will make less money overtime. |

Considering all things mentioned earlier, I would guesstimate that you have problem with ripple voltage on that particular rail. Try to measure ripple voltage using a true RMS AC voltmeter on each rail (AC voltmeter will measure only the ripple component of DC output) - if you measure different value for suspicious rail - you have found your problem. Probably bad capacitor on the rail output filter.
I don't have a RMS AC voltmeter but I will investigate further and see if I can replicate the same result on the other same rail with other connectors and see if switching to a different rail changes anything. I tried a different PCIe connector but it might of been from the same rail. |

So measured the voltages its 12.25Volts without a load. Same as the other rails. Then decided to start mining and measured again at the GPU terminals and the voltage is 12.15V. So it seems the voltages are fine.
It seems that as soon as it starts to mine, right after the DAG loading, the temps jump from 45C to 80C and starts climbing, when I terminate mining, it instantely drops back down to 45C or so. Seems like there is some sensor issue on the GPU itself but only with that PSU.
Very puzzled.
Does it happen to other gpus on just this one? Only on that GPU. I measured the motherboard voltages and they were like 3.4V and 5.1V and 12.2V. So I decided to switch to a 3rd PSU and with that PSU the problem went away. So it seems my most expensive PSU is the culprit. Anyone had this issue before with the Lepa 1600W PSU? Comparing the power usage, it seems with the faulty PSU the consumption was about 15Watts higher, so obviously the temps might be correct. Seems the GPU was shorting out somehow. Puzzling. |

During my time on the forum I have seen merits awarded in a variety of ways, some which were completely rational and others which were quite bizzare to me, this ranges from give aways to newbies, merit for gifs and some other sort of give away for unsavoury comments on CSW. I had my personal opinion on them, but they were not my merits and I couldn't dictate how they could be given. I would only consider an intervention when it was unethical, like merit sales or using it to incentivise posting in an ANN thread, sort of like paid bumps. In these cases the trust system which is equally unregulated by the forum could be used to check it.
Except in cases of extreme abuse, I would rather not scrutinize merit giving as everyone has diverse opinions on what they think is deserving of it.
I've seen this also however most of the merits that I give or that I've gotten is when you took the time to help some poster out. Usually in the mining section people got problems with their rigs, or setting up their rigs or how to buy the right parts. If there is some poster who takes his time to write a detailed post usually he is rewarded with merits. So basically if you put in effort you get awarded however there are times when they are given away randomly sometimes. Someone writes a small sentence and its actually meritted. Very puzzling. |
