banman24, Yes, I done thaht. I already update the bios to F9d (march) version, which is the latest version for this model and still doen't change anything.

I don't know what could be the problem.

When I put 6 card, I get a screen with all kind of coloured lines and the motherboard doesn't boot, with 5 card it's okay.

Use SMOS (Linux) This mobo can run 7 cards if you update the bios to the mining version and use the m.2 slot for one of the cards.

Have 7 rigs running 7 cards with this mobo right now.

Hello everyone! I have an isue with my model from gigabyte Gigabyte z270x Ultra Gaming

After bios update to F9d (march2018) I have the same limitations with the old bios, I can only instal just 5 video cards (maximum), when I put 6 video cards, my motherboard doesn't boot.

I followed this tutorial also, but my Ultra Gaming Edition is not in that list and I don't get it why I don't have that Mining Option in bios menu. What I'm doing wrong?

Neither option worked. Board kept entering an endless boot up and reset cycle before posting. Only option left is to get a M.2 NGFF to PCIE card and that may get you 6. At this point without a bios change I don't think this board can do more than 5.

I also got this loop before posting with a Z270 Gaming 3. I wonder if disabling onboard video would work, anyone can confirm? Also, anyone knows if this board has 4g decoding on the updated versions of the BIOS?

PSU is EVGA 850 BQ and 500w with Add2Psu

I'm using the EXPLOMOS adapter available on Amazon and it's in the m.2 slot closest to the CPU.  The adapter has a 4 pin adapter and looks just like the green ones available.  However, I'm not sending any power to the m.2 adapter.  

I'm also not running the BIOS from that page.  It's the F22i version.  There's a newer one available now, but I haven't updated.  Not sure it matters, but both of my gaming 7 motherboards are Rev 1.0 and not 1.1.

One last thing - not sure it matters.  I have one card directly connected to the motherboard in the x16 slot closest to the CPU.  I'm cheap and didn't want to get another riser.

I'm running Win10.  Tried Linux once and got frustrated when I couldn't get more than 20Mh/card.
Thanks, I think that my adapter is bad or incompatible. My adapter is the kind without the power connector, it's identical to the 'Leboo M.2 NGFF to USB3.0 PCI-E X16 Slot adapter' on Amazon.

I'm also using the slot closest to the CPU, and also running the mining BIOS but I think I'm going to try the latest non-mining BIOS as it's newer, plus the mining BIOS seems a little unfinished, for example there is no way to disable thunderbolt.

I'm running a rev 1.0 board also, I can try running a card directly in the end x16 slot, but I've ordered a EXPLOMOS type adaptor and I'm going to try that first.

EDIT: EXPLOMOS type adaptor arrived today and it works great, I can now detect and mine with 7 GPU's, thanks dude! Smiley I guess some m.2 adaptors just straight up don't work with certain mobo and riser combos

Oops I meant 7 cards, maybe I have a bad m.2 adaptor, my card is connected to the M.2 adaptor but it is not detected under Linux. Riser and card is good as they work when connected straight to the PCIe slot.

Can I ask what adaptor you are using? Is it the green kind with a power plug? or the black/blue kind which connect straight to the riser cable?

Also are you using the mining BIOS from this page:

https://www.gigabyte.com/MicroSite/462/mining.html

Finally which m.2 slot are you using? The one closest to the CPU (M2D_32G)?

Thanks

has anyone managed to have more than 6 gpu's running on this board?

i've tried to get 8 going but m.2 to PCI-e adaptors don't seem to be working, card is not recognised.

very odd, i'm going to try loading BIOS settings from defaults and see if it fixes it

Yes.  I have 7 working on my rig.  Six PCI-E plus one m.2 adapter.  That's the max per the gigabyte mining website.

Worked for me! Followed the instruction and it is able to detect 6 GPU.

I would love to know the answwr to this aswell. I can’t even get a 3rd GPU going. My system just ingores whatever card i put in PCIE x4 slot even if the x8 slot is used or empty.

I’ve tried moving my M.2 NVME SSD around, I’ve tried disabling sata slots.

I will give the “Gen 2” setting a go. But this is driving me nuts and costing me money.

Update:

I have moved the M.2 SSD into M2H_32G as not to disable the PCIE x4 slot. - Still no 3rd GPU detected.
I have updated to the F22f mining version listed in the link above. - Still no 3rd GPU detected.

Other than that actual slot being U/S. i don't know what i am doing wrong...

I got this link from Gigabyte support where they have specific Bios for Mining.
Will be trying this today.

It's been awhile since this post was updated, but I got mine working.
At first, I was able to get only 5 running as well. But I was able to fix it with help of a very smart computer engineer.
You have to update the BIOS.
And that's it.

I got 5 working.
When I put the 6th in things start to go haywire.
I'm using SimpleMining Nvidia.  Looks like he's running ubuntu 16.04.

Could someone please explain how to switch to Gen1 in BIOS of this motherboard?
I have the same issue and 6th GPU is not shown.

Thank you all.

Enter the BIOS by hitting fast the DELETE button. Go to the top right of the screen and you should see an Advanced tab there, and in there there is the PCIE configuration, change it to Gen1.

I had a similar issue with my Gaming 6 MB, I could only get 4 cards to recognize in Windows 10.  I ended up disabling the onboard video and switched to Gen1 for PCIe and had all 6 show on next boot.  I think the switch to Gen1 was the thing that actually made the difference.

BTW, i can only get 5 GPU running on each ga-z170x gaming 7 board.

Have another azus z170-a that can run 6 card and asus z270-a can currently runs 8 card. Will only going to purchase asus z270-a in the future.
