I see,
Well never tried to connect only one power input of a GPU, there is obviously something blocking you to do this, you probably need a Y cable to double properly the connectors, and plug all of them. I don't use AMD cards. but there is something blocking you, does the rig make the POST properly ? you crash @ windows start right ? did you tried safe mode to see if it crash too ?
No its not crashing the 6th card is just not powered. I can start mining with the 5 GPUs no issues there everything very stable. I have to check if some Y cables were included but this is just so weird. And obviously shutting down the rig and trying to solve this problem is annoying and downtime which is never good. |

If a 2nd card on the same cable doesn't start, the power pulling is too much and the gpu don't get enough power
GPUs don't need much power to start, it's not like hard drives or anything with a motor, they consume just a few watts when you turn the system on. True, gpu don't consume much when turned on, but it's weird the GPU doesn't start when it's put in combo with another one, but work perfectly when solo on a cable, maybe there is some sort of protection to protect the PSU or the GPU. What GPU's OP is using, how many 8 and 6pin power connector per card (which brand/model), what does he use to separate the power (Y cables ?) They are all Sapphire RX 570 cards (6) and working with only the 8pin connector branched. Pcie powered with a different power cable for all of them. Separating power was not necessary as I only connect the second 8 pin connector of the PSU cable to the second card and it was working fine. As I previously wrote with the 850 Watt unit everything works perfectly fine. |

Great so we both agree that this needs to happen on a weekly basis! Mate dont take the credit i posted this roughly one week ago it was a rather large post. The idea is not revolutionary but it adds a lot of value as it clearly shows that things are moving and that the project is not abandoned! Thanks for he newsletter and looking forward to seeing this on a regular basis! i don't take any credits, i directly talked with cryptorex on slack and we decided to make it and i didn't see what you made. |

Ok so maybe a faulty GPU then.
No, all 6 cards just work fine with the other PSU. Best is really to never touch a rig that is stable you always encounter problems if you change somehing hardware related. |

I have 16 rigs with this PSU, using 3 cables to power 6 gpus.. havent had any issues. What are your power limits set to?
Power limit on the cards? Its an AMD rig all cores run with 1150 Mhz the entire rig consumes 530 Watt ( will be extended in the future). The consumption can really not be a problem especially considering that the 850 PSU just works fine and powers all 6 cards. Just replacing the PSU ends in only 5 gpus starting. I also don’t believe that the PSU has a technical problem as everything else just works fine ( runs stable for 3 days on a test machine) |

Is this some sponsored blog? Looks very much so also with the URL. I would question the results posted on that page until it’s clarified. |

Yes, its powering 5 cards but if I put the sixth card to the second pcie connector it doesnt power up. The card gets no power whatsoever it actually looks like the card is dead - the system only starts with 5 GPUs. Very weird
I have this same PSU and 6 cards is no problem at all. Have you switched PSU to single rail? Yes I switched it to single and also unplugged it just to be sure that the change is reflected. Still didn’t change anything. Other than that there is not much to configure. The 850 PSU just works fine with the 6 cards @530 watt, really funny stuff |

I have a problem with the Corsair HX 1200 PSU. It works perfectly fine with one GPU per PCie cable. When I put a second GPU to the same cable the card doesn’t even start. It’s not a card problem as I switched them and observed the same behavior. That's weird. I don't have this particular PSU to test right now, but I've got a Corsair RM750i and it definitely works fine with 2 cards per cable — I remember connecting 4* rx 480 to that PSU, each card with a single 8-pin connector, and it only has 2 cables (with 2 pci-e connectors each). Maybe something's wrong with the PSU? Do all the connectors actually work? Yes, its powering 5 cards but if I put the sixth card to the second pcie connector it doesnt power up. The card gets no power whatsoever it actually looks like the card is dead - the system only starts with 5 GPUs. Very weird |

2 card on the same cable is too much that's all there is, don't use more than 1 per card.
So with a maximum of 5 possible connected pcie cables you want to tell me that I cannot put more than 5 cards - even if I only put GTX 1060 which would not even reach half of the PSU capacity? |

Fellow miners
I have a problem with the Corsair HX 1200 PSU. It works perfectly fine with one GPU per PCie cable. When I put a second GPU to the same cable the card doesn’t even start. It’s not a card problem as I switched them and observed the same behavior.
My ressearch told me already to change the button at the back of the PSU to single instead of multipe but It didn’t help.
Anyone faced this issue already or has any suggestions?

I asked over a week ago if we can have a regular newsletter (which is crucual from for investors and also to attrack new miners/hodlers) but I dont see much from the devs these days. Doesnt need to be a 2 pager but a couple of sentences would be great.

I really don’t know how hashflare is gonne survive with the limit bitcoin contracts. Genesis mining is still offering “unlimited” or lifetime contracts. My bet is that they will go bust within one year.

So far the v0.5.6. Runs for more than one day without trouble on GTX 1060/1070/1070 Ti. Great job maybe you can squeeze out a few more percent in the future |

just installed my RX580 its running 576 h/s out of the box it is a hynix memory any advice on improving the performance
Did you even bother to read the first page?Mattthev put already all the information together for beginners. Topic: Is it possible that hash rate is higher with tread per gpu = 2 setting in sgminer on RX 570? Played around with the settings today and looks really stable. |

I think Hush is a much better coin to mine compared to BTG - the potential of Hush is enormous. I minded already some a couple of weeks ago, probably the right time to point a rig back to Hush |

Thanks for the link. I will observe the development and decide if it makes sense to host a node. So far I am really impressed seeing where this is going - mined some Zen a couple of months ago it was much easier back then  |

I can’t suggest to buy the Gigabyte Gaming G1 1070 Ti I personally find it gets much hotter than any other 1070 I owe (same pisition in the rig)
I have the feeling that the supposed to look cool back plate is not helping at all with the heat dispersion. Better go for another model if you have the choice!
At this point, given how many issues I've had with Gigabyte cards the last 3 weeks, I can't recommend Gigabyte PERIOD (except perhaps the Aorus, jury is still out on those). 3 cards with dead fans, 1 with *2* dead fans, and I've had *2* of the ITX cards just flat out DIE this past week. BTW - the "common" 1070 ti has a 29 watt higher TDP than a "common" 1070, why is it a supprise that it would run hotter? The 1070 Ti has a higher TDP that is true but already few months ago I had a 1060 G1 gaming which ran much hotter than the other 1060 with the same hashrate. I sent it back after a few days should have known better. Now I will definitely stay away from the G1 models. Aorus is quite pricy never tried one - do you have any experience with it? Which card manufacturer was the most reliable for you? |

I put together another machine with spare parts and pointing a humble hashrate to one of the donating pool while keeping the gui wallet open. Lets see what the future brings |

0.5.6 works fine with GTX 1070 (regular and Ti) - can't see much of a speed increase but also the power consumption is exactly same as with the old version. Gonna try it out on a GTX 1060 later.
