Arc B570 GPU operating at pcie 3.0 x1 instead of pcie 3.0 x8

• WHQL driver used: 31.0.101.6732

• Resize bar is enabled

The Intel Arc A570 graphics card is running at PCIe 3.0 x1, even though it is installed in a PCIe 3.0 x16 slot. The motherboard detects the correct interface, but the active link speed is limited to x1.

• Processor: AMD Ryzen 5 Pro 2400G

• Motherboard: ASUS TUF Gaming B450M-PLUS II (BIOS updated to the latest version)

• Memory (RAM): 16 GB DDR4 3200 MHz (Dual Channel)

• SSD: 480 GB SATA III WD Green

• Operating System: Windows 11 Pro 23H2 (build 22631.3296)

• Power Supply: MSI 650W 80 Plus Bronze

• Screenshot from GPU-Z showing PCIe x1 active.

 

• GTA 5 Enhanced at very high with ray tracing high in 1440x900 monitor = 30fps
• Lethal Company = 40 fps
• Roblox = 30-40 fps

I tested a rtx 4060 in the same slot, and it worked at pcie 3.0 x8, normally. Tested several other old gpus, and they worked fine. The Arc b570 and the asus tuf gaming motherboard are brand new.

I don't know what to do

Hi kevin2006, 

Thank you for posting in the community. I have a few questions regarding your issue, but first, I want to set the right expectations. The motherboard and CPU currently installed in your system are not part of the supported components for the B series of Intel Arc GPUs, which could be contributing to the problem. However, I would like to gather more information, so please answer the following questions:

1. What is the current graphics driver installed on your system?
2. Have you contacted the manufacturer of your B570 for support?
3. Have you used DDU to completely remove any existing drivers?
4. Have you tested the B570 in another system to see if the issue persists?

Best regards,

Dhanniel M.

The current driver is the latest one, 32.0.101.6732.
No, I haven't tested the gpu on another pc, as well as DDU.

I didn't contact the manufacturer
