It is so funny that all GPUs worldwide are sold out or so expensive, that nearly nobody will buy them...
WTF is happening Nowadays you can make more money by selling your rig(s) then the rig(s) can mine ^^

Because today its another noob bashing day I have another one for you:
http://lmgtfy.com/?q=ethos+gpu+overclocking

But come on, you don't can think that you can build a rig and keeps it running without any searching.
First of all search for your own and them if you realy have problems you can ask specific questions about your problem, and then you get help in here. But nobody will make a guide for every new member which has no idea what he is doing!

Never heared about them, maybe this company uses second or third choice chips for their cards. So they will not be as performant then others, but I say maybe! So if you can get one cheap I would simply try it out and let us now Maybe some other people here in the forum have some experiences with these kind of cards?!

So just in case somebody want to mine with their rig ETH only on two different pools, here is the content of my batch file (start_eth_nanopool_noobpool.bat):


This batch-file gets started from Windows 10 Autostart.
The first 3 GPUs are used to mine on noobpool (no mining fees but high transmission fees!!) and the other 4 GPUs are used to mine on nanopool (also take care if you use this pool).
The command timeout /t 10 /nobreak waits for 10 seconds before the second instance gets opened.

Another thing you have to take care about are the risers. I bought 6 "YIKESHU" Risers (blue, 6-Pin-PCI-E on the riser)  from Amazon and there are all crap! One out of these 6 was completely defect. But the other produce massive problems during the mining. All GPUs where I used these riser, got randomly stuck during the mining. After I changed all of these "YIKESHU" riser to "Ptsaying" risers, the GPUs don't produce errors any more and I was also able to let the GPU run faster with less voltage with these new riser.
So if you got massive problems, the first thing you should do is down-clock your GPUs a bit and if this will not help, you must change your risers! Risers which also work fine in my rig are the "ELEGIANT" risers which I also got from amazon.

Around 2-3 weeks ago Nanopools SIA-Mining-Pool has stopped working. They do not pay the miniers anymore but anyway, there are a lot of miners/workers (22356) right now who only mine for nanopool and don't get any siacoins for the mining.
They do not even inform anybody about this! So be carefull and do not mine there anymore. I do also my ETH mining there but it will be better to switch to another ETH pool! To much strange things are happening on Nanopool these days.
So be warned and have a look at the stats and then immidiately switch to another SIA pool and maybe also to another ETH pool as well.

Hey one question, what happens if I do not claim the tokens before January the 28th. Are they lost from that date?

And it is happening again, the last minutes the coins are again going to the moon! That is realy craizy ...
So don't buy now! Wait for the drop!

Für z.B. noobpool/eth und nanopool/sia und gesetzte Taktraten und Spannungen bzw, Temperaturkontrolle mittels Claymore würde das dann so aussehen:
EthDcrMiner64.exe -epool noobpool.com:8008 -ewal <Your_Ethereum_Address> -epsw x -eworker <RigName> -dcoin sia -dpool stratum+tcp://sia-eu1.nanopool.org:7777 -dwal <Your_Sia_Address>/<RigName>/<Your_E_Mail> -dpsw x -ftime 10 -r 1 -dcri 20,20,20,20,20,20,20 -cclock 1200,1100,1200,1130,1050,1100,1200 -cvddc 875,890,875,900,900,900,875 -mclock 2100,2100,2150,2100,1950,2100,2150 -mvddc 885,885,875,895,908,899,875 -tt 57,57,57,57,57,57,57 -fanmin 42,42,42,42,42,42,42 -tstop 78,78,78,78,78,78,78

Bitte dazu auch die Readme!!! von Claymore benutzen, da stehen dann die ganzen Parameter drin.

Das Problem ist halt, dass nahezu jegliche Börsen immer noch total überlastet sind. Die bekommen/bekamen die Neuanmeldungen der letzten Wochen nicht in den Griff, aber so langsam beruhigt es sich wieder ein wenig.

Also im Endeffekt macht es doch keinen Unterschied ob du nun gewerblich oder privat deinen Strom beziehst, es kommt da immer auf die abzunehmende Strommenge an.
Und lass dich von Gewerbestrompreisen von 5-7 Cent nicht zu sehr täuschen, da kommen dann noch weitere Cent pro kWh dazu und schnell ist man wieder bei >20Cent pro kWh

I also think 50$ is good for some ICO, because I did just the same and invested in the CCRB ICO https://ccrb.io/affiliate/211702
But you have to choose what your feelings are saying to you

Je nachdem welche Miner-Software du benutzt, versuchen diese wie z.B: Claymore auch die Einstellungen der Grafikarte zu verändern. Wenn nun mehrere solcher Tools laufen wird es zwangsläufig Probleme machen. Versuch mal deine Taktraten und Spnnungen direkt mit dem Claymore-Miner zu setzen ohne MSI AB zu verwenden.

Naja kommt drauf an.
Für deine 6 Karten musst du ~1000W rechnen, damit das Netzteil oder die Netzteile nicht 100% belastet werden rechnet man mit ~80% maximale Last auf dem Netzteil. Somit brauchst du ein 1250W oder eben zwei 600-700W Netzteile.

Ich würde da einfach nach dem Preis und Verfügbarkeit gehen. Und Gold-Status sollte es dann auf jedenfall sein!

You seriously using this parameters?
1150/850
2150/875

Because 850mV for the core is quite low at this speed, also 875mV for the mem with 2150 is also quite low.
Are you sure you are not getting HW errors, I mean don't look at HWiNFO64 because it is not showing all errors.
I had also no errors with HWiNFO64 but the cards stopped working from time to time without showing some errors in the HWiNFO64  software.

It is not as much the bios mod that makes your problems, more it is your configuration of the miner. You have to do some undervolting of your gpu clock and mem. If you do no undervolting, your cards need a lot of current! You can do undervolting directly with the miner software or with tools like OverdriveNTool, but you have to keep in mind, that if you run several tools which controll your gpu core and mem clock settings, they influence each other and that makes big problems!

Ich kenn das Mainboard jetzt nicht persönlich, aber muss man bei diesem vielleicht im Bios einstellen, dass man mehr wie 5 GPUs verwenden kann? Bei meinem Z170A musste ich einstellen, dass ich mehr wie 4 GPUs verwenden will.
Ansonsten könnten deine Taktraten auch zu hoch bzw. die Spannung zu tief sein. Bin auch neu dabei und musste auch schon selbst feststellen, dass meine Kiste auch mal 12h sauber läuft und dann plötzlich mal die eine oder eine andere GPU den Miner zum Hängen bringt.
Ich versuche dem nun entgegenzuwirken in dem ich die GPUs die nun immer mal wieder Probleme bereiten, also den Miner zum Hängen bringen, runterzutakten bzw. deren Spannungen leicht zu erhöhen.

So look at this and make it modular!
If someone has 7PCIE-ports they use just the two lower layers.
If someone needs 7 more GPUs they can put a second frame on the first and fix them together (layer 3).
If someone needs another 7 more GPUs they put another frame onto the second frame and fix them together (layer4).

Maybe this idea will help you

I think this really depends on your hardware and how good the wifi connection is. If you have a stable and strong wifi connection I think there should not be a problem, because normaly the wifi connection is much faster then the internet connection. If your rig is far away from your router it will be better to use a cabled connection even if the cable is 40m long

And be carefull with these wifi-usb-sticks. It seams for me, that nowadays a lot of sticks out there are really crappy and often loose connection to the router, it is hard to find some really good ones. Same with some router brands, I bought a lot of new and different models the last year and these didn't worked well. So I switched back to the good old wrt54(gl) with openwrt and ddwrt on them and didn't have any problem

But of course if you can easily connect a cable from your router to your rig, choose the cable not the wifi!

So I also got a Rig running with 7x Sapphire RX580 Nitro + 8GB
5x with Micron Mem and
2x with Samsung/Hynix [GPU1 and GPU5[ (why are 2 Mem's on one card?)
Windows 10
Blockchain Driver
PCIE0+PCIe1 Gen1

The bios for all gpus are patched with PolarisBiosEditor166 One-Click-Patch!
Read and written with newest WinAtiFlash.

The command line to start Claymore looks like this:
EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal WALLET_ADDRESS.rig1/EMAIL -epsw x -dcoin sia -dpool stratum+tcp://sia-eu1.nanopool.org:7777 -dwal WALLET_ADDRESS/rig1/EMAIL -dpsw x -ftime 10 -dcri 20,20,20,20,20,20,20 -cclock 1200,1160,1200,1180,1160,1180,1200 -cvddc 875,885,875,880,885,885,875 -mclock 2150,2100,2150,2150,2120,2100,2150 -mvddc 875,885,875,875,885,889,875 -tt 57,57,57,57,57,57,57 -fanmin 42,42,42,42,42,42,42 -tstop 78,78,78,78,78,78,78

I get a complete Hashrate of 209MH/s ETH and 4150 MH/s SIA with a power consumtion of 1150W from the wall.
ETH: GPU0 30.355 Mh/s, GPU1 30.056 Mh/s, GPU2 30.396 Mh/s, GPU3 30.398 Mh/s, GPU4 29.679 Mh/s, GPU5 28.629 Mh/s, GPU6 30.388 Mh/s

The fans are running at around 50% and the temperatur of the GPUs is around 48-52°C so I think this is not bad at all.


I think I have to tweak the Core and Mem settings (clock and voltage) a little bit more, so I can decrease the power consumption maybe by 50W but I didn't think I get that RIG under 1100W.

Also ich glaube das war eher als Witz gemeint , wieso soll schon beim Nachbarn am Zaun ein Kabel im Boden liegen.
Ansonsten gibts auch noch die Möglichkeit sein RIG direkt an nem Strommasten zu betreiben, das geht aber auch nur dann wenn man ausreichend Youtube-Videos anschaut wie sowas geht, ansonsten bitte nicht nachmachen! 

Aber Strom vom Nachbarn zu klauen ist schon unterstes Nivea-Creme!
