I've had the micro 2 board for almost 2 years now, and I have been noticing a performance degradation. When I actually decide to look into it, I see that the first slot is only running at PCI-E x8. When I previously configured this board everything was running correctly, both slots x16, and my NVME x4. The second slot is running correct at x16. I swapped cards seeing if that would help, but same thing, it runs the card inserted at x8. I tried a couple of different configurations, but it will only run at whatever is inserted at x8. So is there anything else I can try to get this slot to recognize x16 again, or is it time for an RMA?
Thanks!
