8x GPU mining rig

[cleverserge]

Hello, all

Has anybody suceeded in building 8x GPU mining rig on Ubuntu or Win10 ?

I have MSI Z97 gaming 5 motherboards and they work great with 7 GPUs.
I tried this adapter http://www.ebay.com/itm/PCI-E-4X-Female-to-NGFF-M-2-M-Key-Male-Adapter-Power-Cable-with-Converter-Card-/311414541676 and this one http://www.ebay.com/itm/PCI-E-1X-Expansion-Kit-1-to-3-Port-Switch-Multiplier-HUB-Riser-Card-USB-Cable-/191949792720
Both didn't help to work 8th GPU. Though here https://www.youtube.com/watch?v=F9z5bmjEepQ&t=21s the rig is built.
Please share your expertise in this question

Thanks,
Serge

in that video they are using a 3x1 PCIe expander card just like the one you linked too, the common Chinese ones are a bit unstable but you are missing an important piece regardless which expander you use. the BIOS needs to be edited to support that many GPUs. MSI won't formally support it with that motherboard as MSI did not qual that many lanes on the Z97 but you can hack it to do so, I didn't look close but I would hope that video discusses it because there is no way it won't work without a BIOS edit.

The video is how to build 7x GPU rig. There is no problem with 7x GPU on MSI Z97 Gaming 5. The question is about possibility of building 8x gpu rig on MSI z97 G5 or Asrock H81 pro btc rev2 with PCIe extender

My bad.
Not that I'd imagine he'd share with you his configuration if he's selling these, but maybe make contact with wwpat@hotmail.com and ask for some pointers?
If he says no, I'll make contact as I'm interested in this particular setup with diff, possibly a mix set of cards.

For 8 gpu rig you need edit bios motherboard.

Edited bios not for sale

Yes., msi support said that the 270 series can support 8 Rx cards. Not sure if that is true.

Can you share your bios settings, please..

Without bios modding it's impossible to use 8 cards.
