Anyone have an 8 video card rigs?

What is the mobo? Also what kind of multiplexer you use?

I use A88x-G45.

It only supports 6 card with one 1 to 2 pcie. If I try 7 or 8 card it fails.

I think the mobo may be bad.

to exclude MB problem just disconnect everything except CPU and RAM and turn it on, if it post it's good

PC's weren't made to work like this and MB's weren't made to work with so many GPU's so we have to find workarounds

sometimes when there is no post simple CMOS reset do the job
sometimes just switching GPU's location make's it work

alot of trial and error

I use 4 Asus Prime Z270-A with 8 GPUs (7 x PCIE + 1 M.2 -> PCIE adapter).

I have MSI z97 gaming 5 and using 7 gpu. Wondering if I can reach 8 gpu using an extension adapter that can be found on AliExpress. Has anyone tried this with Z97 gaming 5?

That's a very expensive mother board.

My a88x-g45 have 6 pcie but can only support 5. With extension it sort of support 6

Asus Prime H270-PLUS

my 8 card rig is very stable using all 6 slots and 2 m2 adapters.

The z270-A is all that I will use. I have had great luck with it so far. I have 6 mining computers going now with between 6-8 Nvidia GPUs. I am not going to sweat ~$20-50 for a better MoBo when I am spending 4-6k on the overall computer... I went with what I knew would work. Period.

I have ASUS TUF Z270 MARK 2, which has 6 slots + 2x M2 extensions.

Both M2 slots work just fine, but it works only with 7 cards if I put in additional card I get Code 43.
I've tried EVERYTHING, i've read all the solutions for MSI/ASUS Z270 nothing works,...

Has anyone got this mobo working with 8 gpus?

I like your confidence. Not too expensive. Only 1.9 million. Not much more expensive than my A88x.

Anyone using AMD? Any AMD board that also works well?

I too used to use asrock btc. Never have problems with 6 GPU. I never tried using it for 7 to 8 GPU.

In terms of power consumption for high end cards, it is better to use 6 GPU.

i also have this and without extender you can put 10 and 12 under linux, very good mobo, almost on par with the new asrock h110 pro btc, which can go up to 14, but one have two molex other not
