What also nobody pointed out and is pretty important to me is the timeframe. It really matters if you look at profitability on a daily basis or have a more longterm goal let's say over the next 2 to 5 years. So if you would make your books in 2 years you would probably add some other factors (usecase, outlook, technology, community etc.) too, right? I currently only mine ETH but I believe that NEO will probably outperform ETH (not market cap, but bigger increase of its price) since it seems a lot of ICO choosing it over the erc20 token and gains massive popularity. Point is, you could also mine coins that have even a negative cashflow but the value of the coin itself will outperform others. Remember the guys who stopped mining Bitcoin in 2013, because they paid so much for electricity? Guess they wished they had kept those machines up :-)

There a like a million reasons and strategies and possibilities, there is no right and wrong. Nobody knows the future, there will be just some people who do better than others but nobody knows currently if he is on the right side ;-)

/edit: And if you're are talking about profits I can give you a tip for free. Sell all your mining stuff and invest directly into coins. It's the simple truth, buying directly gives you so much more profits than mining.... but that's another topic.

But seems like there is a new gpu batch coming right now, here in Switzerland some shops got stock back again and last week everything was still sold out. However you got still the limitation of 2 cards per account and prices are high.

For sure evn is not a scam but you guys should be more realistic. Promised 161% in return and only 2 MMU built and yet they don't even have the hardware for the others until a couple of weeks / months? Also they did mention that they will pay out dividends first to the big whales and if you combine everything together it's probably not a great dividend at all in 2018. So why would the price rise? They will miss 161% roi this year I guess, longterm I don't know how hashrate difficulty and everything increases.

Nice thank you, seems like a true regulator, guess most of the cheap controllers don't really regulate but rather just cut power to 5 or 7 volts.

@vann, yeah this looks like the master race option

Thank you for your kind answer. Well I'm not so concerned about my temps, think they are still good on my rx580s and also got some reserves left. But the fans came along with the rig so I'll give it a shot and see how much I can benefit or not However  I just don't know what's the best way to control the fans, you think it would work with a small fan controller and chainlink all the fans to one channel? Since psu not possible (no control, 100%) and on connected to the board they won't start.

Hi

I'm keen to know how you control your fans. I would like to optimize my airflow setup and therefore install a 6x fan row. They are all molex powered (some cheap china fans I guess) and chain linked to a single molex adapter. Sure I could connect it directly to my PSU but then I got 100% (too noisy, not efficient). I could use Speedfan tool but therefore I have to connect it directly to my board. Nothing happening when I do that and is it even possible regarding watt if I connect 2 rows à 6 fans (12 total) directly? How do you manage the fan speed of your rig fans? Or should I just buy an external fan adapter like this: https://goo.gl/DoKM67  and connect with an adapter my 2 fan rows? Maybe also switch the fans to those: https://goo.gl/wFZxpu

Here is the picture of my fans: https://imgur.com/a/nLBLz

lol nearly every supplier there is scam, had contact with like most of them

150? count me in as a dealer :-)
But I wouldn't go for Gigabyte, instead for EVGA, MSI or Zotac.

think not, so increase windows virtual memory / set card to compute mode and flip the switch on the card? Open Gpu-z and ATI Winflash and save both files before modding. And modding should be done only with one card (removing the other 5), right? What I don't get, what's the difference between the Polaris Bios EditorSapphire Trixx and MSI Afterburner? Which one is the way to go?

Hi guys, can someone help me out? Im a noobie regarding mining and just started. Just built my rig yesterday and was running a first test to see if everything works. However my hashrates are devastating. Currently all the settings are orginal, so next step is to optimize my system (undervoltage / oc).

Running 6x Sapphire Nitro RX580, 8GB on a ASrock 110 pro. Everything is yet out of the box. System draws currently 1100w.
System: Windows 10 Pro 64bit, 1709
Driver: Crimson 17.11.4 Beta

Did run a "Quick Start" on https://nanopool.org/ for testingt. So far this are my results and funny thing, the two cards with 18mh/s are Micron chips and the other 4 are Hynix . So next goal is to join the 30mh/s club, is this tutorial still the way to achieve it? http://1stminingrig.com/best-windows-setup-configuration-tweaks-for-mining/ --> Tweaking Windows / flash the bios / oc the cards?

But how on earth does alibaba work then? At least for those GPU / PSU stuff it seems like all is fake. And when even "the best" suppliers are not that serious.... think it's a big problem since alibaba is just a marketplace but highly unregulated, every shop / privatperson can sell their stuff. I busted once a scammer and he told me it doesn't matter if I'm taking him down. In 30 minutes he is back with a new name / organisation on alibaba Did ever someone order something there without problems?

I can speak from personal experience since I had contact with at least 10 suppliers via alibaba.com. If it looks too cheap to be true it probably is. Lot of scammers there (they usually only offer Moneygram or Western Union as payment option) and they don't have stock and try to persuade you to send money. Gold status also doesn't count, since everybody got that badge after a time. You can only look for suppliers who offers trade assurance, everything else is scam, believe me. They fake picture of stock and everything, but if you look for trade assurance and other payment options then those I mentioned you're safe to go. But still I'm not convinced if I should ever order over alibaba after those scammers.

supplier with a gmail adress? 

sapphire nitro+ Serie ist das beste was es bei den RX Karten gibt, Asus sicher auch nicht schlecht

Sag das mal Jenen die 2013 raus sind, weil sich btc Mining nicht mehr gelohnt hat

Happy to help but I'm not your servant, it takes me the same amount of time to google it as for you ;-) Also you should look in your local shops, don't know how stocks are looking there.

everything already said, as an addition you could also look for
1.  Gigabyte GA-H110-D3A / ASUS Prime Z270-A
4. EVGA hard to get your hands on, Corsair HX 750, 850, 1000, 1200w is the best out there compared to EVGA

Yeah but you have also take in account that if you wait another 6 - 9 months the difficulty will increase too. So is it worth to wait a couple of months to save 100 -150 per card? However direct investments in coins are always more profitable than mining, that's 100% clear.

ah stimmt habe ich vergessen, bin eben Schweizer, bei uns ist das sowieso steuerfrei

heard about it too, sometimes a 1070 even outperforms a 1070ti, but probably also depending on system / algo. However the ti for sure got the higher resell value in the future. But the Asus 1070 would be the same price as the TI version to buy. Or go with the cheapest and take the MSI GEFORCE GTX 1070 8 GB
