Red VGA LED motherboard

Solved
F0UF -  
 F0UF -

Hello everyone,

Context: I just bought some hardware to upgrade my PC.

New components:

- Gigabyte Z6090 Gaming X DDR4 motherboard

- Intel i5 12600 KF processor

- iCUE H100i RGB PRO XT water cooling

- GeForce RTX 3060 12gb GDDR6 graphics card

Unchanged components:

- Corsair TX 650W power supply

- SSD with Windows 10 installed

- Hard drive

- In win 101 case

I assembled all the components following the steps: processor installation, RAM, water cooling, graphics card, and connections.

Problem: The PC turns on but the VGA LED on the motherboard stays solid red. No signal to the screen.

What has already been tested:

- Removing and reinstalling the graphics card

- Changing the RAM slots

- Using a single stick of RAM

- Clearing the CMOS

- Changing the graphics card (my old GTX 1060)

- Running without a graphics card at all

=> Still the VGA LED stays solid.

Leads:

- Power supply? Old power supply but it worked well with the previous configuration and the problem persists even without a graphics card

- Faulty motherboard?

I'm a bit stuck here :/ Any help would be appreciated!

Thank you in advance :)

When the VGA LED of the Status LED (CPU, DRAM, VGA, and Boot) stays on, it means that the GPU is the problem. Trying to remove the GPU and connecting the monitor to the motherboard could have been a solution to check, unfortunately for you, you have a version F of corei (corei5-12600 KF) which does not have an IGP. There's no point in connecting your monitor to the motherboard. Make sure that your GPU is properly seated in the PCI-Express 16X slot and that the PCIe 8-pin power cable from the power supply is correctly connected to the corresponding socket of the RTX 3060 12GB GDDR6.

Thank you for your feedback.

Indeed, I had forgotten that my CPU version did not allow for a GPU switch.

I verified that it was properly seated. Regarding the power supply, mine only has one x6+2 branch. I had plugged it into the x8 but the GPU does not turn on. In the x6 it does turn on.

=> Do I need both an x8 AND an x6 connected?

I tested with my old GPU, a GTX 1060 with only one x8 connector. The card powers on but has the same issue with the VGA LED.

Is it worth testing with another power supply?

PS: the other PCI slots are too low in the case to be used.

Maybe the PCIe 5.0 slot on the motherboard is faulty. If you can, try calling the customer service where you bought the motherboard and explain your problem to them. They might exchange it for you. In the specifications of the motherboard, they recommend connecting the graphics card to the first slot (PCIe 5.0 16X) although, so far, there is no graphics card with a PCIe gen 5 slot.

Hello

- check in the BIOS if it's booting properly from the SSD, remove the HDD during the tests

- try a live CD/USB with a Linux distribution (without installation) to see if it's a hardware issue or the O.S.

Thank you for the suggestions.

I've tried unplugging the HDD. No change.

I don't have anything to install Linux, and I honestly think the problem lies elsewhere.

The symptom is: I have no image on the screen. I've tested with several screens and the same issue: no signal detected.

Hello

on your motherboard, the white PCI Express slot is a 1* PCIe 5.0 x16 SMD Ultra Durable™ Shielded PCIe, but it may not be active in the BIOS.

your graphics card is in PCIe 4.0 so you need to use one of the other two PCIe slots.

see you later

Well done!

My new card doesn't work if everything is mounted in the case. So, I put my old card in and lucked out, I've got the image!

I can't find a way in the BIOS to make the white PCIe compatible with 4.0... Do you know if that's normally possible?

If not, I'll have to return the motherboard and get one that has a main 4.0 slot.

Thanks again, at least I have the image with the other card.

Oh, it seems I misunderstood you about the PCIe 5X port. Sorry;)

I'm not saying your board isn't compatible, I'm just saying that maybe in the BIOS the port isn't "active"...

Check it in the BIOS in the IO port section:

Here are the different options available in the BIOS. I didn't find any option to enable.

"If your 1060 powers on with just one, that's a big stroke of luck."

No, if it's powered only by an 8-pin, which is the case from what I understand (image 2).

As for the 3060, I completely agree ;))

I misread, his 1060 has a single 8-pin connector, okay.

So poorly seated cards........+ 3060 not properly connected electrically.

I don't quite understand. Is your problem resolved or not? If it's resolved, how did you manage it?

"Regarding the power supply, my power supply only has one x6+2 branch. I had connected it to the x8 but the GPU doesn't turn on. It lights up in the x6."

=> Do I need both x8 AND x6 connected?"

I don't quite understand what you're saying. The RX3060 12G are apparently powered by a PCIe 8(6+2) pins + a PCIe 6 pins. The PCIe 8 (6+2) pins consist of a block of 6 pins + one of 2 pins.

The power supply Corsair TX650 has 2 PCIe (6+2) pin connectors. For the 8 pin socket of your GPU, you connect the 6 pin block + the 2 pin block, and for the 6 pin socket of your GPU, you only connect the 6 pin block. You absolutely need to connect both for the GPU to function. Otherwise, it is underpowered.

Note; "

on your motherboard, the white PCI express slot is a 1*PCIe 5.0 x16 SMD Slot SMD PCIe 5.0 Ultra Durable™ may not be active in the BIOS.

your graphics card is in PCIe 4.0 so you need to use one of the other two PCIe ports

Here is a completely wrong answer. First of all, everyone knows that the PCI-Express standard is backward compatible both ways. Moreover, if one takes the time to read the specifications of the motherboard Gigabyte Z690 GAMING X DDR4, they will see that there is only one PCIe5.0 16X and 2 PCIe3.0 ports that, moreover, are wired in 4X. No PCIe4.0 for GPUs. And yet this answer is marked "Best answer"! It's surprising, isn't it? Or it's a miracle.

Hello,

Well, from reading marcbenic's message, I understood that it wasn't retro-compatible. Upon checking, it is indeed said to be retro-compatible.

That said:

- I connected both graphics cards to the PCIe 5.0 and neither of them gave me an image => Red VGA LED on the motherboard. And for sure, the GTX 1060 was properly powered (8-pin).

- When I placed the GTX 1060 in another slot, it worked. I had an image and no more LED.

- I couldn't test the RTX 3060 in the other PCIe slots because it was too thick.

I had therefore concluded that the 5.0 was not compatible. But you seem to say otherwise, and retro-compatibility seems confirmed.

Question: why is no GPU recognized on the PCIe 5.0?

Thank you in advance for your help!

Hello,

To control the colors (if that's what you mean by your question!!?)

Take a look: >HERE< and RGB fusion

Hello, no, this is not about the color control but the motherboard's LED indicator that signals a VGA error.
