RTX 3090 TI无法启动
RTX 3090 TI无法启动
I had planned to assemble a PC about a year ago when the 3080 was released, but a GPU shortage delayed things. Now that the 3090 Ti is available, I installed it and still couldn’t boot. The GPU shows RGB and fans spin but nothing appears. My setup includes an i7 10700K, MSI Z490 Ace board, 32GB G.Skill DDR4 at 4000MHz, NVMe SSD, and an Ax1600i with 1600W power. No bottlenecks were expected. I suspect the BIOS might be outdated, so I replaced the GT1030 GPU which worked fine before. After updating the BIOS, it booted into the new one. The motherboard now shows a display error light. I checked the error code and it relates to the GPU. It seems the 3090 Ti is compatible with the current BIOS, but it’s not being recognized. My concern is whether the latest BIOS fully supports the Ti model. Also, are there specific BIOS settings I need to adjust for the Ti to function properly? I can access the BIOS via the GT1030 and tweak settings if needed before switching to the Ti.
I overlooked that detail, actually this model handles high power well since it's a Corsair ax1600i.
The adapter includes a 3x8-pin to 12-pin converter, so I’m connecting the three 8-pin PCI-e power pins through the PSU without chaining them. I confirm the connectors are fully seated and the card is properly inserted into the PCIe slot—please reseat if needed. If everything checks out, it’s possible the card is defective. You mentioned a GT 1030 tester; would you like to use another system (especially one with at least 850W power) to verify? Also, can you try the RTX 3090 Ti Suprim X on another machine?
Replaced the card three times. The adapter connects 12 pins to 3 eight-pin slots on the PSU. All three eight-pins are in separate slots, not paired with the two 8-pin slots. They’re single-port connections. I have another PC for testing, but it’s a Z390 motherboard—compatibility isn’t guaranteed. I’m unsure if changing the BIOS settings would help, as that could cause instability. The CMOS reset worked when the board wasn’t functioning, but I haven’t removed the CMOS battery yet, so I might try that.
Ensure everything functions smoothly. With the latest BIOS update, testing on the Z390 machine makes sense since any failure could point to the hardware. You don’t need to modify the BIOS settings on the Z390—there are no required changes to get the card operational. It should launch normally. To confirm it’s not the card itself, try installing it in the Z390 setup and observe its behavior.
I'll test it on the Z390 PC. It already has three 8-pin cables since I'm using a second GPU for PhysX, so it shouldn't be too challenging. I'll keep you updated with the outcomes, thanks!
Your bios should be set to UEFI, not CSM. I’ve encountered issues with CSM before, but since you’re using UEFI now, it shouldn’t cause problems.
You've tested the 3090 Ti with the Z390 and Z490 systems. For the Z390, you removed the 2080 and 970 PHX cards to avoid interference. Both setups showed a D6 error indicating no GPU found, and both had input errors leading to a loss of power. So yes, the GPU didn't work in either case.
