Microsoft Windows 10 (64-bit)

Hello,

 

I can't run my ELGATO 4K60 MK2 Capture card at the right resolution. My graphics card is a 970 GTX dual slot, so I only have the PCIE 19/22/23 slots available.The problem is that the 19 is a x4 slot but only one band is connected as mentioned in the manual below. So it works as an x1 and I'm stuck in 1080p60 resolution when I'd like to go to 1440p120.
I still have slots 22 and 23, unfortunately these slots go directly to the CPU as the graphics card, see manual below. When I start my PC, it remains blocked after the HP logo and the fan of the graphics card does not turn. It seems that the motherboard recognizes the ELGATO as a graphics card and prevents the PC from booting.

So I put back my original graphics card, NVIDIA K2200 single slot, to free slot 21. Miracle, this time it works, slot 21 is a x8 (4) and is managed by the PCH so no worries. Unfortunately I can't use the GPU 970.

Is there any way to change a BIOS setting so that I can connect the ELGATO on port 22 or 23 at the same time as the GPU 970 on port 20?

Thank you in advance for your help.

move your 970 from slot 20 to 23, the video card will not care which slot it's in

 

or if necessary slot 22, even a x8 slot will not really impact the speed of the video card that much

 

once you decide on the best card/slot arrangement, enter the bios and look for "PCI VGA Configuration"

 

Which Configures which expansion slots are used for graphics cards. In multi-graphics card configurations, this option designates one graphics card as primary and the other card as secondary. set the slot the 970 is in as the primary

I don't know if this will help, but there is a setting in the BIOS that allows you to select the primary GPU slot, i.e. the GPU card the PC will boot with. It may be possible to place the capture card in slot 23 but set the BIOS to boot from slot 20.

 

NOTE: The option in the BIOS to select the primary GPU card only appears if 1 or more graphics cards are detected at boot. In the BIOS the PCI(e) slots are numbered differently, i.e.  slot 1 is closest to the CPU, so try installing the GTX card in slot 2 and the capture card in slot 5. On first boot, enter the BIOS and set PCIe slot 2 as the primary graphics display and try rebooting.

 

Not sure if it this will work for you, but worth a try. I have a Quadro P2000 and GTX1080Ti installed in my Z620 and this works for my application.

After putting back the 970 in slot 20 and the Elgato in slot 23, I've checked again in the BIOS. I couldn't find the PCI VGA configuration. I took some screenshot of the BIOS, please check below. 

 

So I decided to go with the second option :

Unfortunately I can't move to slot 23, I have a wifi card on the slot 24 and even if remove the wifi card the GPU don't have enough space.

As you said, I install it on slot 22 (PCIE 3.0 x8 open ended connector) and it's working well. As I see on youtube, it look like there is not a lot of difference in term of speed between x8 and x16. In this way I can install the ELGATO in slot 21.

But now I have a new issue, the fan start to run a bit more faster, so my computer became noisy. It seems to be the power supply fan's and the CPU fan's. Except that, there is no other problem.

 

I'm happy to finally find a solution to run my 970 with Elgato but I'm concern about this fan issue.

 

Please let me know if there is any other settings to improve.

 

Thanks.

Thanks for the help.

the video card bios option will not show unless you have two video cards installed and your elgato appears not to be a video card

 

you are installing two power hungry cards that dissipate quite a bit of heat, so it's normal for the system fans to ramp up to cope with the increased thermal load
