Hey, I see you're facing some tricky problems with your two P40 GPUs on the Z270-P motherboard. You mentioned having over 4G decoding enabled but still getting a PCI resource allocation error. When you try to boot with two GPUs, it doesn't start at all and the BIOS won't appear. The display output is on but not showing anything, and the web UI never loads. It seems like the issue might be related to driver configuration or GPU recognition. Have you checked if the drivers are up to date? Also, ensure that your system isn't missing any essential components or that the card slots are correctly seated. If you're using UEFI, double-check the boot order and firmware version. Let me know what you find!

The motherboard manual mentions support for PCIe SSDs. You might need to assign the PCIe lanes to the GPU slots. Without more details about your setup, it's challenging to identify the problem. Have a great day!

The system specifications are at the bottom. It has 64GB of G-Skill Aegis RAM installed. The Linux USB drive is available for booting, though it shouldn't affect this. You'll need to assign the PCIe lanes to the GPU slots as required by your hardware configuration.

There seems to be a method available through the BIOS settings. However, without knowing your specific BIOS interface, you'll need to locate it yourself. It could involve PCIe lane assignments, configuring port types (x16, x8, etc.), or enabling NVMe ports. Good luck!

No drives at all? NVMe SSDs and SATA ports wouldn’t overlap with PCIe connections.

I did not attach drives because i was having this issue and wanted to see if it was related. Not having drives attached does not fix the issue. I also don't see a setting to allocated lanes. Ive tried switching to Gen1/Gen2 speeds but this also did nothing.

The power supply is rated at 1000W.

Currently, there aren't many options left. Some issues are fixed only by the system itself.

I'll attempt using a different mobile setup designed for mining; it should accommodate around 12 GPUs, which should help get it running. If not, I'll need to explore other solutions. Thanks a lot. Once confirmed the mining board functions, I'll update this post for others facing similar challenges.
