New motherboard doesn't work with specific GPU, but works with others

Qualdan · Apr 15, 2020

I recently bought Asus PRIME B450-PLUS motherboard with Ryzen 7 2700 CPU and Kingston HyperX FURY RGB DDR4 2666 32GB RAM. I have an Asus GTX960 GPU, but attaching that to the motherboard just leaves the monitor black. I tried it with (ancient) MSI 7600GT (from Nvidia) and PowerColor R9 290 OC (from AMD) and with those everything works and I can access BIOS just fine.

I'm not listing the other stuff (drives for example) in the build, because currently there is nothing else attached that could have an effect.

Steps that I have tried so far:
- Removed everything (and I mean everything) and replaced them.
- GTX960 is confirmed working with my current PC.
- PSU is powerful enough (750w).
- GPU gets extra power with 6+2 pin connector.
- Tested 6+2 PSU power with two different cables (PSU is modular, also R9 290 receives power fine).
- Gave GPU power from another PSU (which is also confirmed working on current PC).
- Monitor is plugged correctly to the GPU (and not the motherboard).
- Monitor confirmed working (if plugged to 7600GT or GTX960 on current PC).
- Tested signal from GTX960 with DVI, HDMI and displayport with different monitors.
- Flashed most current BIOS to motherboard.
- Made sure BIOS had primary video as PCI-E (CPU doesn't contain GPU).
- There is nothing extra attached to motherboard (only CPU, RAM, PSU and GPU).
- Several websites confirm that the GPU and motherboard should be compatible (both support PCI-E x16 and UEFI).

At this point I'm at a loss. Anyone have any ideas?

TL;DR New motherboard doesn't like particular GPU, but works with other ones. All parts tested as working.

Try setting the PCI-E generation on the board to 2.0, i know 7x0 cards had that issue maybe your particular 960 does as well

Qualdan · Apr 15, 2020

Thanks for the suggestion, but there doesn't seem to an option for that (only an option to limit PCI-Ex16_2 speed to 2x or 4x).

The funny thing is that the only way I can find the "Primary Video Device" is through search. It is not exposed in the main UI. Couldn't figure any search term that would get me the PCI-E generation.

I'm thinking maybe I just need to return the mobo and get another one from some other maker?

last time I had something like this happen to me, I ended up having to update my motherboards BIOs for the card to work. That was with a MSI Z68 GD80 motherboard and EVGA GTX 780 ti SC video card.

InhaleOblivion · Apr 15, 2020

I had a similar issue with an older motherboard/PC build. I even updated the BIOS as well for that board with an older GPU. The only option that worked for swapping out the board at CompUSA(I was still within my return/exchange period). Wierd thing about it was that I didn't even purchase another brand. I just exchanged it for the exact same motherboard.

I've actually updated to current BIOS. Unfortunately there isn't any newer available (I just checked).

I'm still within my return period also and I might need to go that route. I could also just replace it with another brand, just to be safe.

can you update the BIOS on the GPU?

Ripcord · Apr 15, 2020

have you run the nvidia bios checker for displayport 1.3/1.4 https://www.nvidia.com/en-us/drivers/nv-uefi-update-x64/ it wont hurt

Asus doesn't offer BIOS updates for GPUs (at least for that model).

Does it work on the lower PCIe slot? I know that it's a slower 2.0 x4 connector; I had to use it myself when I had a GTX 780 since GK110 and Ryzen 2000 series have compatibility issues, but I haven't heard similar issues with any other cards.

I've applied the Displayport Firmware Upgrade (it was needed) and will check what happens on the weekend (I need to keep my current PC in working order for work during the week).
I'll also check the other PCIe slot at that time, if the Firware didn't fix things.
I'll let you know afterwards.

It worked on the lower PCIe slot. Would not be ideal to use it on that, though.
If I return the motherboard and get another brand, but with the same AMD B450 chipset, how likely it is that the same problem is on that one?

By the way, Chloe Price, if your location is current, we happen to be living in the same city. What are the odds?

Pretty low from the scale that we're on a forum where there's users around the globe, but yeah, my location is correct.

I returned the motherboard and got a new one, with x470 chipset. Same problem, even with updated BIOS (which specifically stated to Improve PCIe compatibility).

There were more options, which I tested. Gen 1/2/3, nothing. But when I changed PCI_E1 Lanes Configuration to x4+x4 (+however many x4s there were), the GPU works.

So, essentially it will only work on x4 mode on these newer boards. My old motherboard (which is several years old) had it at x16 just fine.

Try to play around with the UEFI / CSM settings. Perhaps something wrong with the VGA BIOS.

Look for an updated VBIOS and then use this firmware update from Nvidia.

Thanks for the suggestions.

I previously applied the firmware update, no help.
There isn't updated BIOS for the GPU.
I did try changing UEFI settings, also didn't help.

If other cards work fine on thah motherboard, something is wrong with the graphics card.

Post a GPU-Z screenshot and its stickers. What BIOS version does it have?

I have tested the motherboard with an ancient 7600GT and it works fine (same thing happened with the previous motherboard).

According to GPU-Z BIOS is be 84.06.0D.00.A1.

I'm afraid nothing can be done.

There is an issue with GTX 900 series and B450 chipset.

Use the 2nd PCIe slot for now. Maybe the upcoming AMD AGESA 1.0.0.5 firmware will fix it.

Qualdan · Apr 25, 2020

Yeah, thanks for taking the time. I was afraid that I need to accept it will only work as x4.
Anyway, I'm thinking of buying a new card sometime later this year, so this won't be a problem then anymore.

Cranky5150 · Apr 25, 2020

Well at least you can get a new GPU and all is well

Wow, this all sounds very familiar! I just bought a new motherboard and processor (MSI Z390-A Pro with an i5-9500) and wanted to put my old MSI GTX 760 video card in it...and it will not even POST. It powers up for a few seconds, then powers down, powers back up, powers down. Bought a new power supply...same thing. Tried a different power supply...same thing. Put the 760 back in my older computer and it works great. Tried a newer 1660 card in the new MSI motherboard - and it works great! But the combination of the older 760 in the new motherboard will not work! Tried both slots - same in both. I have no idea what to try but it's starting to sound like some of the combinations of new MB/old GPUs are a problem.
