Man im trying to follow your guide, after i have installed geth using
sudo apt-get install software-properties-common
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install ethereum
After that i just use putty to connect to my vps
I run it with this command
geth  --fast --cache=512 console --rpcaddr 127.0.0.1 --rpcport 8983 --rpc --unlock COINBASEADDRESS
 the node start just fine

Then i try to run the pool module (ALL IN ONE AT FIRST) and this is a log of what I get

Please add eth, its the second crypto by market cap, and your page even it is very basic I like it a lot more than trading view and cryptowatch to draw charts! you seem to be the only one to have found the perfect size for candles. Also if you add the possibility to scroll up and down the chart it will be amazing (in order to see lines interception on prices ranges much higher than the current ones) sorry for my seriously broken english, it is my second language and I haven't slept properly

Well did anyone were able to mod  the Sapphire Nitro 480 4GB with ELPIDA memory? because polaris bios editor wont read it bios properly, and I don't know how to find the strings with VStraps using a hex editor in order to modify them

I'm using windows 10, as I have told before I have successfuly build several rigs before, like 30 of them with no problems whatsoever ( using the asrock h97 anniversary, until my last batch and the recent out of stock situation), it seems that there is some bios issue preventing the z170 chipset from successfuly handling more than 4 gpu , but i havent found a workaround yet ( to be honest iwasnt able to even find someone developing a solution for that)

Hey thank you so much for answering, I'm having almost the same issues with my  MSI z170-A pro. But what I find really interesting is the fact that the last batch of asrocks h97 anniversary that I bough (six of them from some amazon vendor called outlet pc or something like that), were presenting the same faulty sata behavior, but they did it  when I put the 6th gpu on the system. windows sometimes didn't want to boot and  the solid state disk wasn`t able to pass the seatools tests as long as you had the 6 gpu connected and the system managed to boot. If  i did unplug one gpu or put the solid state disk on another mother board of the same model but a previous batch  the disk did pass all the tests.

So i really like to know what causes those faulty sata behaviors, or how to stop them and at the same time keep using the 6 gpu

I wonder if genesis mining use those regulars MB or if they use some custom made Motherboards and uefis.

Ill give it a try, however i just cannot wrap my head around the fact that the z170 chipset has more pciE lanes compared to the h80 or h97, in every single connectivity feature the z170 is superior to the h97, and somehow the former performs much worse than the later.
I guess that it is a hardware issue, but mostly a uefi issue, so maybe a custom rom or manufaturer update will solve this, however i wasnt able to fin any information of anyone trying to  develop a custom rom for that purpose. And the bios updates do nothing regarding the 6 gpu compatibility issue.

Hi, I have some experience building 6 gpu mining rigs, the mobo of choice use to be the Asrock h80 btc pro or the h97 Anniversary. As most of miners know, those boards are disappearing from the market, I don't even know  if it is a low stock issue which would be temporary, or if Asrock stopped their production.

Right now Im looking for a replacement, maybe a socket 1151  mobo, that is able to handle 6 gpu. I have an MSI Z170-A Pro. The board has enough PCIe to connect the 6 gpus, but with only 5 the system becomes highly unstable, and with 6 its a constant reboot festival.

So my question is, which modern Mother board that is still in production, and is proven to be able to handle 6 gpus  do you recommend? or  maybe any of you were able to run a 6 gpu rig using a 1151 Motherboard (z170 chipset) and you could share how you manage to do it?

Thank you in advance for taking the time to read and answer to this.

Hi guys my antminer s5 is dead, the beagle bone died (already did the micro sd reimaging thing, it didn't work), I don't want to wait 3 weeks and spent 62$ buying a BB from amazon when i have no bullet proof tutorial about how to make it work (and add 2 months to ROI).

I ask for your help because i had seen that the daughter board has two empty data connector for hashing blades and an empty fan connector.

So my question is, what does it takes to build a 4 blades s5?

      A) Do I just connect the two blades and fan from my broken antminer?

      B) Connect the 2 hashing blades, and intercept the fan cables of  good miner and splice them with the fan of my broken miner?

I was wondering if there is no damaging side effect from doing this?

I have the Jan 07  Firmware, the one that came with the 5 machines.

Any help or advice that you could provide will be really appreciated .

Thank you, it kinds of tranquilize me to think that I can get a sparepart kind of fast, how ever even when the 56 $ hurts a lot, what hurts more is not having the guarantee that it will work (imagine that 60$ spent on something that wont help me + more days of  down miner) so it will be amazing if other forums members could shine us some light about this). Im still have to things left to do: using a cross over cable to  connect directly to the miner, and trying to reimaging it using a tutorial As dimke_yu  has written

Thank you so much, I haven't though of that actually, ill try to get a crossover cable or circumvent that issue somehow using a router with static ip list and nothing else connected, luckily i had written down the mac address

I was thinking the same, but i wonder why it will broke while the others miners are doing just fine. Also where can i get a spare part to replace it?
Thank you so much for taking the time to read, answer and help me. You are very kind 

Hi guys yesterday my antminer s5 stopped hashing, I was using it at f2pool along with other 4 machines. I had seen that the rejected rate of all the other workers was 0.2%, while my faulty antminer has a rejected rate of 3.7%.

I had done the following:
1)changing the network cable (Cable is Working perfectly)
2)Changing the psu (PSU is Working perfectly)
3) Tried to reset the machine (i cant get it to reset)

I must said that when I power up the PSU the fan on the antminer goes live, making its hideous blowing noise like all the other 4 machines.

I Can't access the machine via its web interface. the router doesn't give it an IP.

I Tried connecting directly my laptop to the machine via ethernet with wifi off,  Assigning IP 192.168.1.1 mask 255.255.255.0 Default gateway "BLANK", primary and secondary dns "BLANK" to my laptop and putting 192.168.1.199 on my browser to access. IT DIDN'T WORK

I cant use the IPREPORTER.exe it says that it isn't a valid win32 Application.

Using the advanced ip scanner (freeware http[Suspicious link removed]) it can't find the machine range 192.168.0.1 - 192.168.2.254

I Find weird that the faulty antminer cant get an IP, cant hash, however its fans turn on and work like it has always done.

The only thing that i can think of will be to use another S5 and unplug their hashing cards and connect the hashing cards from my faulty antminer to see if it is my PCB that is broken.

Please help me, im Totaly open to suggestions. I cannot lose my antminer because it still needs like another 4 months to ROI itself. HELP GUYS pleaaaase pretty pretty please.

Lol they should make a usb miner with some flash memory  so we could trick our bosses into renewing the whole office usb pendrives XD at least that way we could pack a couple hundreds of gigahash just to pay for black coffe.

Thank you so much for your answer, at first I was kind of mad because on the first yay! msg had a similar timed orphaned block, so I was thinking " damn I got a 1 /238098775 hit and it has to be orphaned, that's some serious badluck Brian meme material. Ill just stick mining with my 5 s5, and hope that antpool doesn't have another 50% luck day

Hello, first post here so maybe it will be stupid.

The thing is, I got 5 antminers s5 mining in antpooll in pplns mode, but just for fun I got a really old pc (2005 amd laptop)doing solo Mining (my energy is free so don't worry), I'm using antpool solo with cpuminer , on the saturday i got a a weird surprise

In case you were wondering this is the command I use to run cpuminer
"C:\miner" minerd.exe -a sha256d -o stratum+tcp://stratum.antpool.com:3333 -u MYUSERNAMEFORSOLO.1 -p 123

What's kind of weird is that in solo.ck.pool I had never got that message. So please could anyone explain why my laptop hates me and plays with my feelings??? 50 BTC means that  have my food and expenses for more than 5 Years XD or that I could grow my farm really fast.
Thank  you guys in advance for all your kind help
