Hello,
As you can see, there are only 5 SATA ports on the PSU. If I have 6 GPUs, where should I connect the last one ?
Thank you for your help.
1) Do not plug in Molex power on the motherboard 2) Use Molex plugs directly to the risers, do not use the Molex to Sata convertors. Pcie powered risers are better but more expensive, and often psus wont have enough connectors to run the risers and the cards 3) Connect two risers per cable, not more 4) That 1600w pus is overkill unless you're running 6 x Vega cards, but thats something to keep in mind for future builds |

Hi,
I am from chennai. I am thinking of getting into Ethereum + Altcoin (DCR) mining. I am not interested in buying a rig immediately. I would like to start Mining with a PC and decent graphic card for a month or so. If I am comfortable with the outcome may be I will be thinking of buying rigs and have a proper setup in Chennai.
Can you guys provide configuration details for Medium Budget PC suitable for Ethereum + DCR mining?
I would like to know your opinion on spending money on hardware instead of buying ETH directly.
Thanks guys.
In all honestly its probably going to be more profitable to just buy the crypto currency and hold it, than it would be to buy hardware to mine it. The only reason I got into mining was because its lower risk, you own the hardware which is a tangible product, and you can resell it later and recover atleast half your investments. So that is a decision everyone has to make. Now if you want to get started mining, its always best to try with what you have first, or as you said try out with one graphics card just to get a feel of things and understand some basics. Start with that and see if mining is for you. Mining requires both time and knowledge, and if you are unwilling to invest either, its best to stay away. There are a lot of setup/beginners guides on these forums, I suggest you go through them, they will help a lot. If you want to buy something prebuilt from me, drop me a Pm. |

Someone please let my country's Graphics card distributors/retailers know the bubbles burst, because the prices sure as hell haven't moved an inch.

 be patient my friend, dont be mad or angry just bc you dont know , dont understand something your time will come ... few more months and you will see the light again ... just like you saw the lights after 6 months about how 8 gpu can work with one mobo Another post without any proof of any of your claims, or without any substance. You really dont have anything better to do, do you? |

if you asking me on the nice way i would be happy to post some picture as i always did when i posted something on this forum , but never going to share how i did it  Says EVERYONE who has nothing to back his/her claim, forget how you did it, you cant even share pics of the result, and expect to be believed ... True, I lived, I learned. Till then the only people who were successfully running more than 7 cards were doing so on modded bios'es on Z97 motherboards. h81 or h85 boards did not support more than 7, Then came the Z1xx series which was a disaster for mining, but with proper bios mods the Z170's could support 8 as well. But the real change came with the Z2xx series when everyone and their mum could run 8 cards easy. I learned from people who had actually done the 8 card setups and could demonstrate/prove it, so that changed my attitude towards the max no of cards. Yes windows can see 9, 10 even 11 GPU's in my testing, but they will not work with any GPU intensive program, so the maximum usable cards is 8. More than that and the system crashes. But ill leave you with a nugget, get in touch with jstenfanop on these forums and hell "Educate" you on max GPU limits, what you can and cant do etc. And next time when someone asks for proof, show up or shut up. |

you are WRONG too I tried to run 10 amd cards under windows and worked fine do you have any experience building rigs ? modding bioses ( modding , not just changing mem staps) , modding mobo bioses ) or just reading articles about what possible and what not its really pita to set up , not a real plug and play solution Show us pics then, of 10 AMD cards mining under windows, if you have achieved it. If you dont have pics, then stfu and crawl back to your hole of ignorance. |

max supported gpu for win is 8 gpu if im not mistaken, anything more than 8 go linux.
WRONG to set up any rig with 12 gpu its easy with the right motherboard , you must to have 6 nvidia and 6 AMD cards , this way the 12 cards setup under widows can not be a problem , really easy to set up . if you want 16 cards it is still possible under windows (10) but might be PITA (pain in the ass) to set up , but once the right configuration is set , you are ready to go i have both 12 cards setup and 16 cards setup running without any problem under win 10 enterprise edition amd cards are with custom bios , latest blockchain driver , driver patch , nvidia cards overclocked/ undervolted with software Hes not wrong, max 8 GPU is what windows officially supports at the driver level for each unique driver. So 8 GPU's that can run off of AMD drivers, and 8 GPU's that can run off of Nvidia drivers. If there was a third co, we could add 8 more, but the max is still 8. |

Hi,
my rig (Asus Prime Z270-A + MSI 1060) works well, when booting up with 8 GPUs (using 1 M.2 -> PCIe adapter).
When booting up with 9 GPUs (using 2 M.2 -> PCIe adapter) the 9 cards appear correctly in Windows 10 64 Bit (8 GB RAM), but miner (tried Claymore and ethminer) won't start.
See the pics. Do you have any plan, why it doesn't work with 9 GPUs? I heard, that one can't use GPUs in both M.2 slots of the Asus Prime Z270-A, but Windows discovered both GPUs correctly:
OP can you please try using half the cards in Claymore, and the rest in another miner? |

I'm selling my Gtx 1060s because they are not very good at mining. Whether it was the Hynix memory, or the bad components used, I only got 17Mh/s out of each card after OCing without touching the voltage. I cut my fingers twice with the fan blades, and whenever the network difficulty changes some of the cards hashrates drops to 1Mhs. I'm getting 22 Mhs from 570 8Gb and want to know how to increase hashrate other than increasing the memory clock, thanks.
Just get out now while you still can. Those GPU's going to start taking toes.  Stop takin a P00P at him  To the OP : Look up Bios modding, your 580 8GB should be able to get 29mh easy peasy at low overclocks. |

Hello, I am using EWBF's CUDA Zcash miner Version 0.3.4b to mine ZCASH. When I open the miner my first hashrate is good: ~ 2550 sols, but after 30 sec the hashrate drops drastically to ~2200 sols This is my batch file: miner.exe --server eu1-zcash.flypool.org --user "mywallet".Miner01 --pass x --port 3333 --cuda_devices 0 1 2 3 4 5 6 x MSI AERO GTX 1070, AsRock H81, Corsair AX1200i. MSI Afterburner settings: 70 power limit, 150 core clock, 600 memory clock, 75% fan speed. https://imgur.com/a/XD4adDoes anyone know which would be the problem? Thanks! Your temp limit is 70, as cards hit 70 degrees they throttle to keep temps stable, so performance reduces. |

Can confirm, 7 cards are detected, and installed in windows but while mining CPU usage will rise to 100% and miner crashes coz of hardware/interrupt errors.
M.2 slot works with Nvidia GPU's, does not work with AMD GPUs. Update : Working with AMD cards as well. @deadsix Hi, can you specify which biostar board you got AMD's working on. The TB250, TB250+, or the TB250-PRO? I only have the tb250 Thanks On the Tb250. |

Hey, I connected a rx 480 to a PCI slot. Not pcie. It smoked! Now my card is not recognized. I've tried in different pc's. Is there a fuse or capacitor that might have blown on the cards board?
Yes if it smoked, it blew a few caps at max. But its not something you can change unfortunately, you'll have to give it in for RMA. |

Hi all,
Did anybody had success in running 7 GPUS Nvidia with this switch on Asrock H81 Pro BTC? I have 6 GTX 1080 ti and when I try to add this hub/switch to add 7th card GTX 1070 the system don't recognize it or I can't boot the system (Windows 10).
When I try to connect 5 GPUs to mobo and 6th card to this hub it doesn't work either. It did work once but this 6th card I couldn't change any settings in MSI Afterburner then after restart stop working. I have two of these and none of them works for me.
If you have any ideas or expirience with this Switch I would appreciate any help.
PCIe 3x or 4x Splitters do not support Nvidia cards, are built primarily for AMD. |

Perfect solution for SMOS would be to have additional two fields (OC page) related to mem/core voltage but as I understand it's not possible. Right?
Its a limitation of the AMD Linux drivers, nothing tytanik can do about it. |

On another note, the new blockchain driver raise the power usage of your cards alot. If your mod was tight you may have to change some things like power limit or max temp.
Why would you say that? Comparing to the 16.11.4 I was running before both unofficial beta and official blockchain beta drivers make rx4xx use LESS power in a range of 2-5%, measured at the wall. Whats working for you for stable undervolts? AB beta16 or Overdriventool? |

I dont understand the bios modding. What am I to be changing on my Polaris cards I am only get roughly 20mh/s out of them on ETH.
When i load the bios following instructions, they say change timing, the timings are all kinds of crazy hex numbers.
I also get an error about my bois being too small
You cannot use GPU-Z to save the BIOS as it only saves half of modern bioses. You must use ati flash to save the bios. You are copying the memory straps from either 1500 (hynix, micron and elpida) or 1750 (samsung) and pasting it to all memory straps higher than it, such as 1650, 1700, etc up to 2000 or higher. This makes the memory run with tighter memory settings so hashes more. But it can also make the card unstable and/or crash. How do I tell memory brand... also I am using ATI flash to pull them. They appear to already read as 2000 as thier default memory speed? When you start GPU-Z, it reports the memory brand. Also use the following article for BIOS flashing as it tells you the correct Polaris BIOS editor version to use in order to get rid of the craxy hex numbers you're seeing: http://1stminingrig.com/sapphire-nitro-rx-470-8gb-oc-bios-flash-mod-tutorial-hynix-samsung/Okay all m y cards are hynix so I can OC them a bit? My screen for timing looks nothing like his.  You are using outdated version of PBE. Find a good step by step instruction with the links to the 1.4.1 version The most current version of PBE is v1.6. It now includes 'one click' bundled performance timings. Very easy to use. Just save your original Bios using Atiwinflash and open it in PBE. The 'one click' option automatically applies the bundled performance timings and then save the bBios and flash it using Atiwinflash. https://bitcointalk.org/index.php?topic=1433925.msg21518785#msg21518785This version applies performance timings to the 2000 strap by default. Any way to get it to apply performance timings to a lower strap? |

I'm using ASRock H110 Pro BTC+ & as soon as I connected my 3rd GPU it told me to give it more power via molex. I would never try to power a GPU with molex or SATA, I'm just looking at powering the last 2 risers(10 watts each) off of a 2x molex to 2x 6 Pin connector.
I am curious what others use or what best practice is, if there is one?
Thanks!
My bad then, I thought you wanted to power GPU's with the molex/sata. I am assuming here you have the Risers that take pcie plugs? Sure you can use Molex to pcie adapters to power those, but do not use sata. Even the Riser can pull upto 75W if its an AMD GPU. |
