Topic: Boot loop Issue with 4th GTX 1060 with ASUS Z270P motherboard and Windows (Read 891 times)

After reading the thread i was going to suggest switching to the mobo onboard graphics. Works for me.

were you able to solve this?  except I have trouble with 4th rx 570 card.

I am in same boat.  I am able to use 9 gpus on linux but windows 10 doesn't work with more than 3 gpu.  Plugging in 4th gpu even with 4g decoding just gets stuck in a boot loop or other weird issues.

what's the BIOS version btw?

EDIT:  Solved it.  Not sure what was the cause.  But I changed the display in BIOS to auto and plugged the DVI into the primary pcie slot GPU. 
That didn't cause a boot loop anymore and was able to get into windows.  Then all the cards were freshly detected and drivers installed automatically (because I had them installed for the other 3 cards earlier before getting stuck in a boot loop)

I have same mobo with 5 GPUs, sometimes there is problem, but I have only 4G above and PCI-E set to auto.
I have pluged monitor in so... My screen sometimes doesn't show anything, but boot in to the bios and switch primary gpu to auto works.

Thanks for your reply mate, I really appreciate it.

I have enabled the  - "Above 4G decoding  ON" option in the advanced settings.

Will try the other option too ('PCI GEN1')

* Having no monitor is definitely not the problem right?

I will update the BIOS as soon as I can.

Thanks Mate.

Might be:Bios setting to PCI GEN1  (advanced menu) and Above 4G decoding  ON (it is in the Boot menu)
Update bios first

To make  a fresh start pull Power Plug . So Bios lights  are all out.

I'm also stuck in the same loop please help

I've also seen this error too

please help me

thanks!

Hello Guys,

I've started building a GTX 1060 (6 GPU) Rig using ASUS Z270P mother board.

This is what I got -

2 x EVGA Supernova G2 750 Watt PSU.

6 x GTX 1060 (with latest drivers - 382.53 released on 09/06/2017)

ASUS Z270P with 8 GB single card RAM

Windows 10 latest Trial

Using 1 PSU -

I started with 1 GPU first and then added 2nd GPU which was working fine, after some time I tried to add 2 more (to make it 4) motherboard doesn't boot in windows and restarts continously, can see and access boot menu but can't boot into windows. Got stuck with this restart loop. Firstly, I thought it was PSU issue, so I waited for the Dual PSU link cable to arrive and add the 2nd GPU. But it allowed me to run on 3 GPU without any issues (but only drawing 330 Watt from single 750 Watt GPU)


Using 2 PSU's -

After getting the Dual PSU link cable, tried to connect all 4 GPU's with all combinations like, all molex-->sata-->PSU connections to 2nd PSU and power supplies from 1st PSU. Swapped cards around, but nothing worked.

after all the trials its still allowing me to run 3 GPU's perfectly well using 1 PSU.

Can somebody please help me with you suggestions from your experience, I would like to try all the possible solutions.

My possible guess-

* Windows trial version (not sure it matters as its not even booting into windows with 4th card, but works with 3)

* I'm using TV (using HDMI output) as my monitor, with no proper monitor (slot is empty, haven't bypassed it).

* Risers (with molex to sata cables), not sure about the version

* Power supply combinations

* BIOS settings/update?


Note :

1) I've also enabled the encoding setting in BIOS.
2) Does using peripheral slot to power GPU's matter?

Any suggestions would be really appreciated.

Reg.
