[SOLVED] PCIe 4.0 graphics card doesn't work on my PCIe 3.0 mobo ?

[satimis_06]

Hi all,

Just purchased a new GIGABYTE GeForce RTX 3050 WINDFORCE OC8GB GDDR6 display card, PCIe 4.0. It won't work on PCIe 3.0 motherboard. I tested it, no signal output on either DP and HDMI ports

Motherboard:
ASUSTeK COMPUTER INC.
PRIME X570-P
Version: Rev X.0x

Is there anyway to make it works on PCIe 3.0 motherboard? Please advise.

Thanks in advance.

What GPU were you using before? This GPU/motherboard are definitely compatible. Has this system ever worked?

Also, this mobo definitely has a PCIe 4.0 slot:

You shouldn't be facing any problems, PCI-e is backward compatible and should work. Does this GPU works in another PC? Or did another GPU worked before, as stated above?

Hi,

Thanks for your reply.

Graphic comes from AMD CPU

$ cat /proc/cpuinfo | grep AMD
vendor_id : AuthenticAMD
model name : AMD Ryzen 5 3400G with Radeon Vega Graphics
vendor_id : AuthenticAMD
model name : AMD Ryzen 5 3400G with Radeon Vega Graphics

Yes, there is another PCIe slot, I'll test it if the problem not coming from AMD CPU

Hi,

This PC is working without problem

When you installed the GPU, did you connect you display directly to it, or did you leave connected to the motherboard video ports?

When you installed the GPU, did you connect you display directly to it, or did you leave connected to the motherboard video ports?

I connect the display, 4K 32" Dell display, direct to the DP port of the new PCIe 4.0 graphic card. After booting up, it turns to a dark screen finally. I can boot BIOS making change there. I have tested the HDMI port of the display card. It is the same, no signal finally, a dark screen resulted.

The HDMI port of the MOBO is still working. I have tested it.

Lets start with the basics. Are you sure your PSU has enough power to run the card and did you connect the PSU cables to it? Did you uninstall the old GPU drivers?

A)
I think the PSU having sufficient power, Before I have a 4K PCIe 3.0 graphic card installed on this PC. The PCIe 3.0 graphic card worked on this PC without problem. Later I removed the PCIe 3.0 graphic card to my spare PC. Now it is still working on the spare PC.

Yes, The fans of the new PCIe 4.0 graphic card are turning.

I can make following tests:-
1) I have a brand new PSU on shelve. I can install it on this PC
or
2) Install the new PCIe 4.0 graphic card on another PCIe3.0/4.0 slot of the motherboard
or
3) Test the new PCIe 4.0 graphic card on my spare PC wtih PCIe 3.0 slot on motherboard

B)
Uninstall the old GPU driver. I'm not aware it. Please advise how to uninstall it?
(Before when I installed the PCIe3.0 graphic card on this PC I didn't uninstall any driver)
This PC, a daily working PC, has been running 4~5 years.

Thanks

uninstall old gpu drivers, REBOOT, install new gpu drivers

 

[Teknoman2]

If you have another PC, try putting the card on that one to see if it works.

Hi all,

Install the new PCIe 4.0 display card in the spare PC which works without problem on a MSI 4K PCIe 3.0 graphic card.

Result is the same. It boots to a dark screen finally with a few lines of words on the left top corner. Unfortunately I couldn't read them because the characters are too small.

The cooling fans of the new PCIe 4.0 display card stop.

However also I can boot to BIOS making changes there.. Please advise how to test further?

Is the new PCIe 4.0 display card having problem ?

Thanks

Regards

It does sound like the GPU is the problem. Can you return it?

 

[plausible_deniability]

I don't know if he has installed any gpu drivers on either machine much less uninstalled the 3.0 drivers and installed the 4.0 drivers on the main machine. When asked if he uninstalled the 3.0 drivers before installing the 4.0 he said how do I uninstall the old drivers?

 

[hotaru.hino]

The card looks like it has problems. If you can't even get it to display the boot screen or BIOS, which is practically a requirement for any video card to have, then that's a problem.

 

[plausible_deniability]

In post #12, he states he can also boot to BIOS and make changes there.

The post appears ambiguous as to what that means, because ...

Result is the same. It boots to a dark screen finally with a few lines of words on the left top corner. Unfortunately I couldn't read them because the characters are too small.

... implies that there's still problems in the boot stage. A lot of either boot or pre-boot outputs fit this description.

But if we're going to nitpick here:

I don't know if he has installed any gpu drivers on either machine much less uninstalled the 3.0 drivers and installed the 4.0 drivers on the main machine. When asked if he uninstalled the 3.0 drivers before installing the 4.0 he said how do I uninstall the old drivers?

There's no such thing as PCIe 3.0 or 4.0 drivers. PCIe communication is handled seamlessly by the hardware itself and by the time it gets to the OS, the OS doesn't even need to know what version the bus is running on.

It's like how your internet browser doesn't care if it's running on a dial up, satellite, or fiber.

Hi all,

Performed following test;

Install the MSI PCIe 3.0 display card of the spare PC to the daily working PC
MSI graphic card V292 R1
Model: MS V385

Connect to DP port

It works without problem
-> booting to grup menu -> starting Ubuntu 22.04 desktop login page finally

lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation TU116 [GeForce GTX 1650 SUPER] (rev a1)

Please help to find out and fix the problem of the new Gigabyte Geforce RTX 3050 PCIe 4.0 display card

Thanks in advance

Did you try the other 4.0 slot you have to rule that out?

Did you try the other 4.0 slot you have to rule that out?

Tried other 4.0 slot

Problem is the same booting -> GRUB menu -> finally a black sreen with following lines on the screen left top corner resulted;
.......
[ 0666180] blacklist: problem black listing hash (-13)
/dev/mapoper/vgubuntu-root; clean 464621/12193720 file
266138082/487756560 blocks

Then it hangs here. (I use a magnify len reading them)

I can boot BIOS and change the data there. The cooling fans of the graphic card are still turning

The motherboard is badly designed, leaving almost no space to insert the graphic card.

With a 3400G CPU the top slot is PCI-e3.0 and connected with 8 lanes instead of 16.

What BIOS version is the motherboard running?

What's the brand and model of the PSU?

Hi all,

I found out the cause of problem, PCIe 4.0 graphic card unable to work on PCIe 3.0 slot of motherboard. It works without problem !!!

My Ubuntu 22.04 desktop is running on a PCIe Nvme 3.0 SSD. This is the cause making PCIe 4.0 graphic card unable to work.

Following OS are also running on this PC.
1) Windows 10 on STAT6 SSD
2) another Ubuntu 22.04 desktop on SATA6 SSD

I just checked them. PCIe 4.0 graphic card works on both of them without problem. I'm now replying this thread on 2) above.

Is there any way to solve the problem, PCIe 4.0 graphic card unable to work on PCIe Nvme 3.0 SSD ?

I won't inject further effort on my spare PC because I won't install PCIe 4.0 graphic card on it.

Regards

I'm glad the card works. Better than having to return it cause it didn't work.
