BIOS doesn't detect RTX 4070 Ti.
I recently purchased a brand new RTX 4070 Ti from Gigabyte to swap in for my old GTX 1070. I planned to install it today and double-checked the PCIe slot had two 8-pin connectors properly connected. After installing the graphics card, I thought everything was set. But when I switched back to the GTX 1070, the BIOS didn’t recognize it. I tried reverting to the original setup, but Windows still relied on Intel UHD Graphics and I couldn’t get any video output from the GTX 1070 either. I attempted several fixes: changed the GPU to another PCIe slot (it wasn’t listed in either slot), verified all power cables were secure, listened for the click sound from the slot to confirm proper seating, reinstalled the latest Nvidia driver (version 528.02), forced PCIe to Gen 3 in BIOS, and switched graphics settings to use the PCIe slot directly instead of the CPU or auto mode. I’m running three NVMe SSDs on the motherboard. Could this configuration be limiting PCIe lanes for the GPU? Also, I’ve noticed the fans aren’t spinning even though the logo lights up. There’s a concern about insufficient power from an 850W supply. Edit 2: ASUS just launched a new graphics card under the “Model Identifier” section in Armoury Crate on January 10th, 2023. Might it be that they haven’t updated the motherboard drivers to support my GPU? Here are my specs: ASUS Maximus Hero XII WI-FI, EVGA P6 850W, Intel Core i7-10700K, G.Skill Tridentz 32GB RAM (4x8GB), Gigabyte RTX 4070 Ti Gaming OC, 2x Samsung 970 EVO 1TB, 1x Samsung 960 Pro 250GB.
Current latest motherboard BIOS release is available online. Check manufacturer websites or trusted tech sources for updates.
Clear CMOS first, but note down the boot configuration from the BIOS (boot disk priority, CSM value, RAID settings, Intel VMD, etc.). This might help restore the 1070. Check if your motherboard supports changing the CSM setting (legacy BIOS/UEFI)—this could affect Windows boot. Refer to the manual for bandwidth sharing between M.2_2 and PCIEX16_3; avoid using both at the same time. When M.2_2 runs in x4 mode, PCIEX16_3 is disabled. You might try removing all M.2 drives and testing the GPU in the PCIEX16_3 slot. This should be connected to the Z490 chipset, while PCIEX16_1 and PCIEX16_1 should link to the CPU (based on Z490 spec). If you need more options, consider testing the GPU on another system to confirm functionality.
The fix came from upgrading the graphics card and using the STRIX Z370-E. I also installed the BIOS update beforehand, but video output appeared only after the Geforce driver was updated.
I previously assisted a Discord user again with a comparable problem... I mentioned the 4k series cards often have problems. I understand from a fellow gamer who experienced an issue with a defective 4k card that it can melt connectors and sometimes cause fires. I’m currently using a 2060 Super on my new build, and so far everything is fine. I was hoping to get a 4k card but after hearing the concerns, I decided it wasn’t worth the risk. AMD R9 3950X (16c/32t) 64GB DDR4 Corsair Vengence RGB @ 3200MHz (4x 16GB), NVIDIA RTX 2060 Super (8GB) from Gigabyte, and an ASUS ROG STRIX X-570-F with 256GB and two 2TB NVMe SSDs (planned additions). I haven’t connected the drives yet.
I've attempted a similar solution myself. I updated the BIOS to the newest release. The problems occur when trying to set up the Nvidia driver since my motherboard doesn't identify any hardware in the PCIe slot. This causes the driver installation to stop during compatibility checks because it can't recognize any graphics components.
