[SOLVED] Looking for a solution to run two gpu's in one pc.

[iTRiP]

Right, so the last time I tried running my pc with my second gpu alongside my first gpu, my pc did not boot.

Thought this ought to be another thing I might get sorted, with some help we can get this done.

I'm going to try installing the hardware now again!

What 2 video cards and for what reason?

What 2 video cards and for what reason?

Don't suppose it matters, but like I have had them both installed and running simultaneously with my previous motherboard [previous motherboard: Gigabyte B250M D3H rev1.0 bios version F9] & now the one where I just keep getting boot loop [Current motherboard: Gigabyte B460M D3H rev 1.0 bios version F2] .

I'd just like to get some help to figure this out such just for the reason to complete the objective of having it running.

Think you can assist to figure out what I need to resolve in order to make it run like previously observed.

No answer from my question so no answer from me.

Oh,I'm terribly sorry I really forgot to mention the gpu's: An AMD Readeon HD7950/R9 200 3GB & AMD RX Vega 64 8GB, thought did slip my mind because I'm posting here in the Graphics cards section might be wrong, because I thought this might be motherboard related, could you please still help me figure this out and possibly point me into following the correct procedure to resolve this?

 

[iTRiP]

Meanwhile I found this older thread, where something related give me a clue that my issue might be bios unupdated related:

[SOLVED] - Boot loop and GPU problems ? | Tom's Hardware Forum (tomshardware.com)

Looks like I'm going to need to complete a bios update successfully on this motherboard of mine I'm currently running.

 

[iTRiP]

Right so I created an new usb with a format of FAT32 and MBR partition, downloaded my latest bios update, extracted and copied that file to my newly created usb, rebooted and saved my current bios too the usb as well, then I updated my bios with the new bios file (whilst having my fingers crossed that it just please not screw up whilst doing so).

Now my bios or (UEFI) is updated to the latest version available, and I'm going to go reinstall the hardware mentioned above again and see if this is what was required to make my second PCIE slot working.

 

[iTRiP]

Awesome, I think the bios update resolved my Second PCIE slot issue, running both gpu's now!

 

[iTRiP]

Now theres just the issue of the AMD latest driver not allowing both Newer and older GCN based gpu's to run simultaneously and being managed via the AMD control panel as it was prior to 2020.

I suppose they can still make it work like that again right, until then I'm running smooth with both gpu's in one pc under windows 11 with a UWP drivers without access to an AMD control panel to manage both cards, luckily I can still see both cards's gpu temp in the task manager.

And this UWP driver is only WDDM 2.6

 

[iTRiP]

Update, found a driver with a AMD control panel to manage and control both GPU's in my pc, this driver supports both the older and the newer gpu's, it's running on windows 11.

Driver version 21.5.2 and it's at least WDDM 2.7, had a bit of a hiccup getting the monitoring to function normally as it would have been perfectly working in windows 10.

Well now it all runs as to be expected, I can utilize and monitor both gpu's again without issues!

 

[iTRiP]

Update: Windows update over written my config as to be expected, now my control panel is gone again and again I can't monitor my gpu's.

Now I have some mix and match driver combination of an 21.5.2 and 22.10.20 without a control panel, but hey at least windows update is happy!

I don't think it's all that stable, out of all the variations of drivers I think the UWP driver that got installed automatically the first time worked the smoothest.

 

[iTRiP]

Update: With windows 11 the only way one can get smooth performance with this kind of gpu's config seems to be to have both gpu's running the same driver, Like I have noted now this is not how it used to be possible on windows 10 or rather exactly like it was on windows 10, but the one difference being that windows 11 overwrites anything the user or administrator has done (I know one can customize that, but that's not the point) to get any and all gpu's running with the latest possible driver and this is where such an attempt to run simultaneous variant of gpu fails to either run smooth or without windows errors.

As a last note I would not recommend trying this, unless Microsoft and say AMD in this case resolves these issues with drivers. It's quite the trouble when windows 11 runs into errors that wrong drivers cause, and I for one would not accept continual use of an operating system in such a state or even if it had encountered such errors and then supposedly recovered or restored itself, because it don't seem like that function is working right either way.
