Hardware mismatch detected in Intel x520-T2 device.
Hardware mismatch detected in Intel x520-T2 device.
I just got two Intel x520-T2 10GbE adapters that appear in Device Manager as Ethernet Controllers with specific hardware IDs. When trying to flash them using Intel's BootUtility, the wrong device IDs caused them not to show up. Can you find a solution to get these cards working again?
Did you buy them from eBay? There are many questionable Chinese replicas for the x520 and x540 series cards. Can you share a high-resolution image of the cards? I’ll be able to identify them from there, especially since you have a pair of x520-T2 cards in your server. If your card lacks a YottaMark sticker, it might be fake or from an OEM supplier such as Dell, HP, or SuperMicro.
