Asus prime Z270-p

[heavyarms1912]

Hey guys, I've got the h270plus which is pretty much the same.

I've got 7 GPUs working, and manage to isolate the issue to M.2_2 slot.
That's after swapping everything around, m2 riser, gpu, and all.

It doesn't matter if I use GPU as monitor or iGPU, it won't detect the card that's plugged into M.2_2 slot.

When I only have 6 GPUs, I tried one of them on M.2_1 and that works, when I move it to M.2_2 it doesn't work.

So yes, isolate that to M.2_2 slot. Regardless of the number of GPUs.

I have tried all different combination of bios settings, no luck.

This is the type of riser I am using which is M2 to USB 3.0

I think that might be the issue?

All the videos I saw online that runs 8 GPU successfully is using M2 to PCIE

Could that be the issue as one is 16X and the other is 4X? And to do with M.2_2 not able to work with the 16X card?

I've ordered the 4X on eBay and that will take a while to get here.

If anyone else has any insight, please do let me know how you get 8 GPU working.

1 x M.2 Socket 3*1, with M Key, type 2242/2260/2280 storage devices support (SATA mode & X4 PCIE mode) <-- x4 PCIE
1 x M.2 Socket 3*2, with M Key, type 2242/2260/2280 storage devices support (both SATA & x2 PCIE mode)*1 <-- x2 PCIE

In my opinion the m.2 adapters are not reliable enough (I was using the one similar to 2nd link that you posted).  Also, the build quality are terrible on those.

I had experimented with one and it burnt.  Luckily I was debugging my rig when this incident happened and I could turn off the rig in time.
I am using the below 1x 4x Multiplier adapter and don't use the m.2 to pcie adapter.  I am not sure how many you can plug in on a single board but So far I have tried only 1 MUX.  Each can support 4 cards.  So effectively you get 3 additional pcie slots.

Simplemining on the M.2 drive failed to boot, simplemining on SSD failed to boot, re-installed windows and I'm unable to even install drivers for graphics card...oh well of to the RMA land it goes...

Thanks for your input, may I know when you are using that m.2 adapter that burnt up did you connect a cord to the floppy socket on the m.2 adapter?

I've also ordered a PCIE 1 to 2 adapter, slightly cheaper.

May I know how many cards do you have in total for the rig?

yes it was powered through that.  Molex-floppy adapter.  However, even the gold fingers that go into the m.2 adapter were off.  I had to fiddle/nudge a little to make them recognizable.  I only used one and was done with it.

Hi guys, I'm new to this forum but not to technology.  Thank you all for posting solutions that worked for you when trying to get all 6 GPUs (on risers) to work on this MB.  For me it was keeping things at Gen2 and plugging the HDMI into the first GPU (not on motherboard which was what I was doing originally) to have Windows 10 start and recognize the remaining 5 & 6th GPU (one at a time).

My Question:  (I have done a search but I couldn't find any solution apologizes if there was one that I missed).

How do I go back to using the motherboard GPU for windows desktop stuff and leave my 1080ti GPUs running 100% dedicated for mining AFTER I got the 6 GPUs recognized?  When I plug my HDMI into the motherboard with the 6 GPUs it goes into the Black screen flip loop, meaning that after the BIOS starts and tries to start windows, it just flickers and goes back to trying to start windows and flickers, loop.  Works fine when I plug the HDMI into the first 1080ti GPU but then my hashing power is less with that specific card of course.
I did try to set the BIOS to Graphics Card only and tried AUTO.  I know if I set it to PCI-E it will disable the onboard GPU (so to speak).  I disabled all the non-used USB and SATAs.

My RIG:
Asus z270-p (with latest BIOS V1002)
4 GB
Intel G3900
6 x ASUS ROG Strix 1080ti (with the latest NVIDIA drivers)
Windows 10 (with latest updates)
2 x EVGA 850 G3 PSU

TIA

Have you disabled fast boot on both BIOS and Windows?

I have read that you are not supposed to connect the molex-floppy thing if you are using powered riser. That is meant of the older design of riser which is not powered.

i have the same board and everything pretty much worked out of the box for me.

updated BIOS
set 4g decoding enabled
set m.2 to pcie
pcie link speed to gen2

both m.2 slots and all 6 pcie slots work fine.

im using these m.2 adapters: https://www.amazon.com/gp/product/B074Z5YKXJ/
im NOT using the power connections as they are not needed

if you've isolated your problem to a single m.2 slot then the board is likely defective, i didnt have any issue like that, it just works. RMA time.

Perhaps.  But mine wasn't getting detected unless it was powered

Yes, I have tried that and still get the black screen of emptiness after the BIOS starts (hangs). I am able to get into the BIOS setting no problem but after that no go.

Might want to reset your BIOS configurations and start again?
From experience, after booting past the logo, the screen will go dark and shows no signal detected for a while, can be quite a while, before it lit up again and launch into windows. But if you get the reboot loop, might want to reset Bios and start again.

I hope not. But I've lined up a few options. Will know when the components arrive

After a 2 long hours I finally was able to make this board work with 8x 1080ti!

I’m on phone right now but if anyone wants my config let me know!

[JustinJX]

From my observation, having the monitor plugged in to GPU doesn't affect the hash rate.
I set the windows to turn the screen off automatically after 1 minute.
I also switch the monitor off on the wall when not using.
