8 Nvidia GPU's on one rig

[Alfred Asparagus]

Any one here running 8 Nvidia GPU's on one rig? I have 8x EVGA 1060 Mining GPU's and for the life of me I cant get all 8 to work at once. Always just shows 7.

I have tested each GPU 1 at a time and they all work. Thought it was maybe the M.2 to PCI-E adapter but I bought a new PCI-E 1 to 4 splitter and still no joy.
I have replaced the riser and the USB Cable and tried extra power but nada

What is the rest of your setup?

 

[Alfred Asparagus]

Asus prime z270-a mobo. 8gb ddr4 ram. Celeron cpu. 1000w gold psu

In the device manager it shows the Intel onbord graphics regardless of what I choose in the bios and I think that is the issue

I got 8 x 1070's on one rig and never had an issue, using a BTC pro board with 8 PCIe slots. Possibly m.2 riser?

Get a mining board.

The whole setup worked before on this exact board. Thought it was the m.2 riser so I go a PCI-E multiplier and still only detects 7 GPU's. Its a windows issue I am sure

You need to disable the iGPU in the BIOS. If you see it in Device Manager, then it’s still enabled. Sometimes it’s under Multi-Monitor.

 

[Alfred Asparagus]

I have looked but cant find and place to disable it. You can only choose primary

 

[vinodh]

try this?

1. Navigate to Advanced tab
2. Navigate to System Agent (SA) Configuration
3. Navigate to Graphics Configuration
4. Locate iGPU Multi-Monitor and set it to Disabled

 

[Alfred Asparagus]

Went there and there is no disable for it. Ive updated the bios and tried and still no way to disable it

 

[vinodh]

You need to dig around in there to change from IGFX instead of PEG/PCI. It might be set to Auto.

Use a Mining OS on a USB & see if you can replicate the issue.

Its on PEG at the moment

windows kak bud, just use either SMOS or Hive, won't have this rubbish. Windows not good for mining at all.

what's the most you can get running at once?

 

[Alfred Asparagus]

what's the most you can get running at once?

7 + the on board

 

[Colonel Sanders]

7 + the on board

Have you tried using a gpu as the main display instead of on board graphics?

 

[Alfred Asparagus]

The bios does not have a disable setting for the on-board. All you can do is choose the primary which I have but the intel shit keeps showing up in device manager

What’s changed since you had 8 running till now ??

I had an issue once with a celeron cpu and had to upgrade it because of this issue.

It was something to do with “lanes” in the cpu and not being able to accommodate a number of gpus simultaneously. Upgraded the cpu and all were detected.

Windows has changed...

Windows x64 will support 8gpus
Which version of windows you running ?

Windows x64. Device manager shows 8 just the wrong 8. It shows 7 1060's and 1 intel POS.

What 1 to 4 splitter did you get? Link asb?
I’ve tried 1 to 3 and either only slot works or they don’t support nvidia cards

 

[Alfred Asparagus]

Bought it from Titan Ice. It's a Biostar and it works fine with Nvidia cards. Oh and thx to Malhuis for recommending Linux based mining Os. All 8 cards mining away fine since I switched to Linux
