Title: 8 GPU motherboard : how to boot it ? Post by: ico7liv2 on August 25, 2018, 02:15:11 PM Hello,
I need your help. I bought this 8 GPU motherboard : https://www.ebay.fr/itm/8GPU-DDR3-SATA-Mining-Motherboard-8xPCI-E-Extender-Riser-Card-For-For-BTC-ETH/153069705789?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649&autorefresh=true I previously used a H81 pro btc, with a gold Enermax Power supply. So : I connected all 8pins in the smallest side of the big board https://preview.ibb.co/j0XLA9/DSC_0037.jpg I connected the 6pins in front of the blue PCIe where the motherboard is plugged. I used the 8pins processor connector from the Enermax power supply for that. https://preview.ibb.co/gA1rHp/DSC_0036.jpg I have to notice that the big 24pins ("MAIN" connector) from the power supply that goes usualy to the motherboard, can not be plugged in. So I don't understand how the motherboard could start when I power on the power supply... https://preview.ibb.co/eennq9/DSC_0040.jpg > Do you know how to power correctly this kind of 8gpu motherboards ? > How to make it start ? Thanks for your help ! Title: Re: 8 GPU motherboard : how to boot it ? Post by: blackline on August 25, 2018, 03:43:47 PM https://www.dslreports.com/faq/9208
look at this How do I run my ATX power supply without a motherboard? Title: Re: 8 GPU motherboard : how to boot it ? Post by: ico7liv2 on August 25, 2018, 09:51:09 PM Ok, thanks. I tried that already, but my power supply did a weird stuff. something like start/stop/start/stop in a second.
But maybe, i did not maintain a correct contact with the wire. I did not know that I have to keep the 2 pins together. I will try it again. Does someone use this motherboard ? Is it the correct way to boot it ? Doing my investigations, I read people use server power supplies, instead of classic PC power supply as I do. And regarding the 6pins connectors all around the big card, should I plug them all ? (9 on the longest side, 8 on the small side) Is a molex adapter (molex>6 pins) with only black (ground) and yellow (12v) wires (no red 5v) is ok ? Same question with sata>6pins adapters ? Thanks a lot Title: Re: 8 GPU motherboard : how to boot it ? Post by: blackline on August 29, 2018, 09:45:49 PM you shold plug all 6 pin left side
all other output for vga Title: Re: 8 GPU motherboard : how to boot it ? Post by: blackline on August 29, 2018, 10:02:12 PM you must use 6 to 8 pin vga cable for do this
i tell you again you must plug power only left side 6 pin power others for 6 pin output for plug vga power with 6 to 8 pin vga cable (if you use gtx 1060 6pin power then 6 to 6 pin vga cable) |
