I was given a superseded Precision T7400 several years ago. I've steadily upgraded it with later processors and more RAM. Currently it has two Intel Xeon X5470 quad processors (3.3 MHz) and works well with Windows 10. However, Microsoft's latest rules around win 11 state that although my processors are fast enough, they must be a minimum of 8th Generation and higher which makes it suitable for TMP 2.0 and Secure Boot.

The processor mount is LGA771 Socket: Is there a processor for the T7400 motherboard that will solve my problem please?
