The problem is that the motherboard very often does not recognize/even detect the graphics card – it behaves as if the slot is empty. Sometimes, the system hangs for a long time without displaying any image and, in such cases, usually switches to the integrated GPU. When this happens, the RTX 4090 is not visible at all in the device list in Windows 11. Interestingly, the issue most frequently occurs during a system reboot. A cold boot after a longer time usually (99% of starts) works fine, and the card initializes.

From what I have gathered, this is a known issue with this graphics card and Asus motherboards using the X870 and older X670 chipsets. A friend of mine is experiencing the exact same issue with an ROG CROSSHAIR X670E motherboard and an identical Strix 4090 card. This is extremely frustrating, considering we are talking about top-tier hardware from a reputable manufacturer, costing a significant amount of money. These components come from the same Strix series and should work flawlessly, yet there is clearly a compatibility issue preventing the motherboard (or CPU/chipset?) from detecting the GPU.

A similar issue with this same graphics card is demonstrated here: YouTube link. While there are some differences (the motherboard shown is from Asrock), the detection problem appears to be similar. The Strix 4090 causes issues, whereas the Nvidia 4090 FE works correctly.

I should also mention that no PCIe storage drives are connected – only the graphics card is installed, meaning the entire PCIe bandwidth is available for it. All BIOSes (MB & GPU up to date).

On my previous Maximus XI platform with an i9-9900KS processor everything wokred without problems. After switching to a new motherboard, processor, and RAM, these issues started occurring, while the rest of the hardware remains fully functional. This clearly indicates some software-related issue.

Once the system successfully boots up, everything works perfectly and stable, but having to gamble whether the PC will start or not after reboot is unacceptable.

I would really appreciate your help. I have been using Asus motherboards for 25 years, and this is the first time I regret my decision… I am unsure whether the problem lies more with the BIOS of motherboard or the graphics card – but since both are ASUS products, both Strix series they should work together.

You're advised to include the specs to your build in your thread's body as sig space specs can and will change over time. When that happens this thread and it's relevant suggestions are rendered moot to the end user in the same boat as you're in now. It's with this in mind I've shoehorned your specs in your thread's body.

Did you reinstall the OS after the platform swap?

All BIOSes (MB & GPU up to date).
For the sake of relevance, what BIOS version are you on for your motherboard? Have you tried reflashing with the latest BIOS version and then clearing the CMOS? Try and disable the iGPU in BIOS.

I agree they should work together, but after watching the Jayz2Cents video it appears you may have a VBIOS/mobo BIOS incompatibilty that only Asus can fix.

Not much more I can say, apart from checking old and new BIOS downloads for the GPU and the mobo. There might be a combination that works, but it's a long shot and you could end up "bricking" your GPU.

If you do decide to reflash the GPU BIOS, I'd suggest doing it on another (more stable) mobo. Perhaps in a few months Asus might issue a fix, if they receive enough complaints. I suggest you should contact Asus directly.

1. Understand
2. Yes. New system installed (W11 Pro). Earlier I used W10. But its not system related issue I think.
3. 1104 for MB (tested on 1003 and BETA 1103 too), for GPU latest from oct 22 from Asus site (this BIOS was defaulty installed on my GPU - its 1.5 years old. I tried to refresh. Not helped. iGPU in BIOS I keep disabled. But when RTX is not detected - it posting for very long time (over 40 seconds) and MB turns on its own iGPU to "auto" in BIOS (it posts with iGPU only so its quite obvious that iGPU turns on/auto).
4. Below 2 years old (bought quite before RTX4090). But like I said - it wokred without problems on eralier Intel platform (i9-9900KS is also power hungry) with this card. Also 100% stable (earlier platform and now) during heavy loads.

I contacted with Asus - for now no answers. 🙁
My friend has Crosshair motherboard (earlier X670 chipset) so also high model of Asus board and gets simillar problem. In his case pushing reset button helps to reinitialize GPU but in my case not helps. More-less issue is same with exact same GPU - but I dont know if he asked Asus for help.
If GPU is initialized correctly during post computer works withaut any issues (for whole day idle, load, work etc.) To be honest I dint see any bluescreens or other hardware errors for years on my builds.
