Looks like it has 3 full size PCI-E slots, so three cards can fit without risers and more with them.

Hello everyone

I am looking for a solution to my problem:

On my pc for gaming

I have 2 rx 480 nitro

I do not modify my bios to take advantage of the latest AMD driver (17.1.2).

I have windows 10.

With my rx480 nitro + @ 1342mhz / 2000mhz memory

I get 27.3 mh / s with the following settings: 1125 mhz / 2200 memory and -100mv

With my rx 480 nitro @ 1276 / 2000mhz memory

I get 24.5

Regardless of the memory setting at 2050, 2100 or 2200. I have no hashrate gain.

I try these settings: 1000mhz / 2000mhz memory -30mv

With this setting -276 mhz in clock and - 30mv I have no loss of hashrate but a gain in W.

Why does my card have no hashrate gain when I change the frequency of memory?

Thank you in advance if you have the solution

cordially

Yep.  That's pretty awesome actually.  Guess it's linux-based.  Hard to tell.  Hard to blame him for soft-peddling that, I guess.  

Wonder how much graphics simplemining is pushing through the pipes.  Wonder if it needs X to be running on the host machine.  Just thinking with the MBA side of my brain, I don't think that's the optimal way to do it. I don't think that's the direction it's going.  I see the AMD world tossing X to the curb. No idea what nvidia is up to, but I think OpenCl is the eye of the storm, and from what I've read, that is and has been moving in the direction of bypassing X altogether.  Not quite there yet, I don't think.  But I think that's where it's going.

I'm assuming there's always been client-side software in the mix.  Question I have is, can ALL the graphical stuff be client-side.  I mean, it's not 1984 anymore, right?  

Got a nickel says your average miner would do anything to ditch the graphical environment.  Suspect most do, if they can.  Suspect those who do bring a lot of expertise to the table, or else pay for it.

So yeah, could be an opportunity there.  Host-side product that is delivered (and maintained) with drivers, software, scripts, networking and security baked into the pie.  Client side software ported to...  well that's the thing.  Kinda feel OP is looking at it upside down.  Big task trying to figure out how to build from scratch.  Build the app first, and I think everything else will start to look quite clear.  Put it this way.  When he starts looking to see what's lurking beneath the surface of android, chrome OS, chrome browser, steam --  I think he's going to be pleasantly surprised.

Now, the question is, where does he add value.

I'll start with the proposition that miners aren't precisely "making money," and speculators aren't precisely "investing."  We are engaged in the process of providing liquidity for people who are willing to pay for it.  That's what gold miners do, and that's what we are doing too, only better.  No gold miner ever offered to guard your gold against theft, keep your books for you, and open up a "Paypal Gold" account for you.  OP is right about that, and right about how important decentralization is to the whole scheme.  

And he's right about the need to get power to the people, because up until now, liquidity was a government problem.  Your average guy seldom runs into a liquidity issue.  I mean, if you really have to sell your car right now today to afford tuition, yes you have a liquidity problem.  If you don't have enough assets to pay your tuition, that's different.  

Things are different now.  Every man, woman and child in India has a liquidity problem right now today.  Every Chinese dude who wants to invest in American or European securities has a liquidity problem.  Every guy in Venezuela or Zimbabwe who is tired of working for "money" because he can't convince the guy at walmart to trade toilet paper for it has a liquidity problem.  

This is the interesting and subtle part about OP's proposal.  It's that jillions of ordinary folks around the world are gonna be willing to pay for liquidity (and anonymity, and hedge value), and that it would be kinda good for ordinary folks to facilitate that.  I mean, we don't want to double the hashrate overnight.  But we don't want the network to be dominated by a few government-approved whales, either.  

Where he's not quite on it is the ease-of-use thing.  Screw that.  That misses the point entirely.  It's not that, I dunno, Africans are too stupid to figure out network security.  It's that everybody's time is worth something, and if people are going to run a node -- which is what it's really all about -- it needs to be worth their time.  The only entity that can consistently afford to waste money is the government, and that's how the whales get in.  

It's about making it work.   It's about making running a node businesslike and efficient.  And I think the key to the whole thing is getting rid of unnecessary complexity.  Which means, getting rid of unnecessary overhead and uncertainty.  

Look.  I like my Mac as much as the next guy, but once I got the idea in my head to build 10 or 20 mining rigs, it occurred to me that the GUI is a Faustian bargain.  I'd rather eat worms than manage a 20-node Windows network, and Ubuntu isn't much better.  Either way, I'm always one upgrade away from down time.  In both cases, I think the graphical environment is the problem.  Of course it is.  I look at my work computer.  It's not just that they make us use Windows, not just that, as a result, they have insane hardware and IT costs.  It's that they make us use Citrix.  Which means, we are running Windows inside Windows.  Even when it works, we are trying to cram all those graphics through these little tiny pipes, which wouldn't seem so tiny except to the extent that we make them so.  I can't believe they can afford to pay me what they do to sit there and watch the spinning hourglass of death every time I click the mouse, not to mention having to boot Windows multiple times every day, because it never works for long.  Not to mention having to boot it TWICE multiple times every day.  Who thought that was a good idea?  Have we lost our minds?  And running xorg-xserver-GDM-metacity-unity on 20 machines that never interact with a human is even worse.  I mean, windows can't help what it is.  Linux should know better.  

Meanwhile I've been trying for the last month to prototype a rig, and every time I turn around I'm changing my protocol because some new version of radeon-turbo-nitro-OC-pro won't talk to this week's version of X-almighty-whatever, not to mention the fact that my motherboard is constantly accusing me of feeding it the Stuxnet virus.  And just to be clear, the kernel is sitting over there saying "I didn't do it," and I believe it.   It's the graphical environment every doggone time.  If I could figure out how to compile the software without it, I would.  Fortunately, it doesn't need anything with an X in it to run, so I kick that sucker, and the trash it hangs out with,  to the curb as fast as I can.  My feeling is that the people writing the code feel much the same way.  

Now, I'll startxfce4 (or nowadays I guess I have to ask systemctl to handle it, don't even get me started) if it's the most efficient way to do what I want to do, and sometimes it is.  It is not the most efficient way to keep my machines running and talking to each other.  It's the opposite of that.  

That's the point.  Ease of use ain't the thing.  I'm not stupid,  I'm busy.  So if you're talking about my money?  Deliver me a host product that works, and keeps working.  And a client that lays out what I need to know without having to ask for it, basically.  You're doggone right I'd pay for that.  You don't need to make it easy, not exactly.  I mean, we don't engineer the cockpit display in an F22 precisely to make it easy.  We lay it out in such a way that the human brain has direct access to critical information without going through a translation paradigm. We are removing clutter, removing intermediate steps, taking some of the workload off the brain.  Removing unnecessary complexity and overhead.   I know that's what you really meant, or at least on one level I think that's what you meant.  Stay focused on that.  

Key to the whole thing, OP, is to solve the right problem.  The GUI is the problem, not the solution.  We baked the icing into the cake, which was a mistake.  If you can dig us out of that mess, you win.  

My simpler solution, just cost $20 in my country with arduino module and 30 mins read document and do code, can reset 45+ rigs, can extend to unlimited rigs with register shift.
Have webserver and api too.

By the way i monitored the gpu loading while mining zcash which is core intensive not etherum and also by the way i was mining zcash with nheqminer by cpu but the loading was 100% stable all time.

Hello!
I'm a newbie miner and I'm from Russia. I've been watching bitcoin and coins for 7 years but only now I made decision to participate and it's not easy. Actually in this 7 years it becomes more and more complicated to dive in.

GPU mining community needs an easy way to setup most efficient mining for rigs. Tons of messages like "Help me to setup my rig!!1" appears here and there. Setup and maintain a most profitable mining rig is way too hard because it is really complicated. Miner need to read tons of forums just to choose the software then he need to always watch for updates for mining software and pools. Also there is bios and drivers improvements and updates.

I think all this can be done by developing all in one mining OS and providing a Plug'n'Play solution for users who are willing to give their hashing power for the network and community but who have no time to understand all these tech things. They should just choose what coin to mine and mining mode (like aggressive or power-saving) and that's all. Everything else should be done by professionals and enthusiasts who will participate in the OS development.
Development should be done by professionals by using bounty system. This bounty should be provided by the community through donation.

How do you guys think?

TOLUD works only if you boot to windows with code 12 error

if no screen then try to update bios or some extender is bad, try with 4 GPU then add 5th

Hello,
Do you have exactly the same configuration?

Go into the bios try to find
TOLUD "Top Of Lower Usable Dram"
set it to 3.5G

its somewhere under PCI-e where the integretaed graphic is also set......

It goes higher than that: https://ottrbutt.com/tmp/xmrwolf-01222017.png

Lol id love to know about my infamous bullshit claims. What I have to say about this subject does not make me an entitled prick. What happens when an open source community is taken over by greed is this exact thing...no I dont have to use his software but I have no choice but to do so, until awesome efforts like zawawa's open source miner catches up to hardware limitations and levels the playing field for everyone, and the little miners take in as much profits as the big farms and the system works as intended.

And no I also dont have anything against rewarding early devs for their optimization work ( I have supported both optiminer and claymore with dev fees since day 1 even though I could turn them off), I am a developer myself and get it (even though all my work is open source). What I do have issues with are ENTITLED devs that charge what is essentially a subscription fee to their software, charge ridiculous fees that eat into most of our profits using our power and hardware, then act like children when the people funding them ask for improvements and fixes to basic issues that a 10% miner should not have.

Sure...im the entitled one haha

I hope this is helpful for some of the ZEC miners out there. I welcome any comments/criticism as I tried to be as non partial and scientific about this as possible.

Anyone?
