Pci-e slots on the mainboard seem to be the primary factor.
I believe there are extenders to create more slots. PCIe bandwidth isn't an issue because you can run a miner with one lane, so 1 16 lane slot could drive 16 GPUs mining theoretically. OS and driver limitations could be an issue since neither Windows nor Nvidia are opensource. Linux and open source AMD drivers (do they work?) might be a possibility since anyone with the skills could mod the code to raise the limit. |

Thanks for the replies on this. Everything was on stock settings as I hadn't had a chance to try and tweak anything. So I rebooted the box a couple more times and tried to watch MSI Afterburner to see if I could figure out what was happening. Sure enough when I tried to start ccminer the power, and temp shot to the moon and then crashed the video driver. Not sure why since it was still at the 1060 core speed and 1350 mem speed. So I cranked it down to like 600mhz on the core and turned down the power to 80%. I then started the miner and it would start and run at like 40khs. I slowly put things back to the stock setting in MSI AB. However the speeds did not increase from the card. I noticed on the runs where it was crashing the speed was about 200khs before it crashed.
So now when I try to adjust the speed up in MSI AB it still does not increase the mining speed. So I don't know if I need to unlock these cards or if there is some trick to getting any speed from them. I am still baffled why it would behave this way out of the box and act like it was being super OC'd and crash. Now I can't seem to get it to pick the speed back up.
Thougths? I checked the physical and virtual memory and both are at 16gb so it appears it should have enough swap. Thanks again for the feedback.
Update: I just told MSI AB to reset, then I rebooted, and then tried to start ccminer and it appeared to overload the gpu again and just quit. I did see the has rate increase to 140-160khs just before it hung. So Windblows is updating right now, then I will try a different card to see if the same thing happens.
How many GPUs do you have and what's your power supply model? I think he's trying to get one card working. I think it's a HW problem, GPU or MB, maybe power but unlikely with only one midrange GPU. Maybe a bad PCIe connection, are you using a riser? powered? Maybe a bad slot, try another slot. Swapping GPUs should nail it. |

It's a boring Sunday afternoon so this topic popped into my head. There' been a lot of discussion about
rig building with some nice pictures, very interesting stuff.
But how big is too big? What is the limiting factor? Power limits of household circuits comes to mind
but that can be overcome with commercial power. Hard limits in software? With a well matched CPU and
lots of RAM just how many cards could a single rig support? Most big rigs seem to have 6 cards,
are there any bigger?

Well the weather is nasty outside today so I have been trying to get this Nvidia rig up and running. I just cobbled together the basics, downloaded the Nvidia drivers, and the free copy of sp_ ccminer. I only have one gpu connected to the mobo at the moment and wanted to see if it would at least run before I connect up the other 5 gpu's. I start ccminer and it runs for about 10 seconds and then the nvidia driver crashes. What is the preferred nvidia driver version to be running with these cards using ccminer? This rig is Windows 7, i3 Haswell cpu, 16gb ram, 128gb ssd, and 6 ea 750ti's with 4gb ram. Any tips to get this rig up and running would be greatly appreciated. I am connecting to zpool.ca and attempting to mine neoscrypt. Am I just missing some switches or configuration to make this work? This is the first time trying to run ccminer. Thanks.
Added: I downloaded the 1.5.80, but now wonder if I should be running the 1.5.74 instead. My nvidia driver version is 365.19.

The only time I've seen a driver crash is when I OC too much. I presume you tried a different card. |

Rather than me running around
trying to find out where I can pay other miners to mine 2bacco coin,
I thought I would ask you in this thread.
I want to know this because 2bacco is doing some crowdfunding,
and I can add this price to the crowdfunding.
Where can I pay miners to mine 2bacco coin?
How much will it cost to pay miners to mine 2bacco coin?
Thank you
Nicehash or any other hash rental service. |

No, you are wrong. Car speed on highway is a memory frequency. But latency is a time needed for car to reach full speed if for some reason it was forced to stop before.
I see. That makes sense. 980ti was an example, 970 is much better tha 750ti currently, i think, and with 750ti you can not mine etheruem anymore
Yes, currently I have about 140 days to ROI per 750 Ti and about 118 days per 970 after electricity. I haven't mined Ethereum in weeks though. For me a 980 Ti would cost exactly twice as much as a 970 but it's far from being twice as fast. I can't say for sure but the 980 Ti is probably the worst Maxwell card to buy for mining - unless you can get them very cheap. The 1070 will likely be the winner for Pascal as well but we'll see. I can't resist these types of discussions. Latency, using the highway analogy, is the time it takes to get from point A to point B. Acceleration is ignored, you are assumed to be instantly at full speed. Throughput is how frequently the cars arrive after the first one. |

I still have a lot to learn about c/c++. I got burned by pointer arithmetic this week. It seemed only logical
to me that "p + n" would be a byte offset while "p[ i ]" would be scaled. Surprise, the're both scaled.
My next issue is how to consolidate the definitions of frequently used text strings. In my native language
it's a simple matter of defining the strings in a header file and referencing them in many source files. This approach
causes multi-def warnings in c/c++.
I often see #define macros but they result in the strings being copied by every reference.
Does anyone know of a way in c/c++ to have one definition with multiple references that don't make copies?
-fmerge-constants Attempt to merge identical constants (string constants and floating-point constants) across compilation units. This option is the default for optimized compilation if the assembler and linker support it. Use -fno-merge-constants to inhibit this behavior. Enabled at levels -O, -O2, -O3, -Os. Thanks Pallas. The description of this option indicates it tries to merge multiple explicit definitions of the same constant which means I'm worrying about nothing. I'm trying to merge explicitly defined identical constants by making a single definition while it seems the compiler will do it transparently. Outsmarted by the compiler again, I just wish things wouldn't break when the compiler overrides my code. |

Crackfoo
Is the pool sending out a false high pay rate on blake2s and blakecoin algo's ?
My miner is stuck there. Are those similar to DECRED ?
It's stuck on those.
Crackfoo should I take them out of my conf file ?
Thx
Make sure you scale correctly... *** values in mBTC/Mh/day (mBTC/Gh/day for sha256 and blake algos) |

This coin really exploded on Yobit the price is nearly 3 times what it was just a week ago, seems like it could be another yobit pump though, non the less it's still a huge profit opportunity. Unfortunately, all my HODL is tied up in term deposits which I am kind of disappointed about especially since I have no idea what the price will be next march lol, I wish there was a way to cancel a term deposit and take like a little penalty so to speak.
If you could do that the price wouldn't be so high in the first place. With all those nuts tied up there isn't much to sell so the price goes up whenever there is any buy demand. |

is there a GPU miner out there yet private or free
HOdl is heavy on AES and GPUs don't have HW AES so there's not much motivation. |

which 1 is the latest miner? reinstalling my windows and cant get any miner works for suprnova
Probbaly missing some dependencies, did you install openssl? There may be others. it keeps saying stratum requested work restart That's not you. Read back a bit about the DDOS at Suprnova. |

download is dead ? anyone mirror ?
Cudaminer? Is it even still relevant? I suggest you download one of the ccminer forks discussed in this forum. |

Hey Fuzzballs, love your charts.
Is there a way to zoom out? Some charts (ie net hashrate, net diff) only cover a small
set of blocks. It would be nice to be able to see the big picture.
I also don't get the "hold shift to pan". I shift, click drag but nothing happens.

i only use nicehash because it easy to use and it will be converted right away to btc unlike minergate you need to set up by yourself, and the earnings from nicehash is completely acceptable.
Just to be clear, at Nicehash you don't mine coins you mine contracts and are paid directly in BTC for your hash. There is no coin exchange, orphans or luck involved. On the other hand there is no opportunity to receive any other currency except BTC. Conversely if you're buying hash you pay in BTC regardless of the coin you want to mine with that hash. |

Over the long term the pool with the higher hashrate will find more blocks though, even if it's only one user mining.
Then whats the problem with maxminers.net then? Last 24h its 400% unlucky block found. I am not a statistician but I have an opinion: luck. I agree with uowner, over time it's the hashrate that will win. The distribution of block time varies from 0 to infinity. Slow blocks can take mutiples of the average time so a couple of very slow blocks would require a larger number of fast blocks to average out. Let's look at an example of finding 2 blocks with a estimated TTF of 1 hour. The first blolck is found immediately but the second takes 4 hours. That's an average of 2 hours/block even though the luck seems evenly distributed, one very good, one very bad. It would take two more blocks found in zero time to match the average 1 hour TTF. |

Yes the pool has loads of shares to calculate because the DDoS bogged down the calculations, it's currently catching up but will probably need a few hours until it has fully catched up with the calculations.
Awesome, thanks - definitely not complaining because as always, the pool's been super stable, and I for one liked the new interface haha - only thing I found myself missing was the worker stats box on the dashboard. all should be good by now. I'd recommend using the other pool(s) as well at least as a backup as I don't know if the attacker comes back. There still appear to be some issues. I'm getting some workers dropping off the list occasionally due to infrequent share submissions, but I'll ride it out. Cheap shot: I wouldn't have been able to tell with the new interface.  It's curious that the ddos coincided with the price rise. Edit: The stratum diff is much higher than previously. My i7 often has a diff over 10, that never happened before. It's been over 10 minutes since my core2quad submitted a share. I don't know if it has anything to with the ddos or mitigation or unrelated. |
