Gigabyte has announced that it would recall and offer an exchange for its Z690I AORUS Ultra motherboard after the discovery of various PCIe 4.0-related issues. Gigabyte learned about cases of "system instability and WHEA PCIe errors" when the motherboard is connected with specific PCIe 4.0 graphics cards and devices. While the company has offered replacement motherboards, the company stated that setting PCIe to Gen 3.0 within the BIOS would eliminate the problem.

Gigabyte has created a program to give users experiencing this issue an upgrade to the Z690I AORUS ULTRA PLUS motherboard, or one very similar to the model mentioned. If customers do not want to proceed with a replacement, they are free to apply for a product refund.
