Re: W540 CPU upgrade

CPU should work normaly after upgrade. Just make sure to reset BIOS to default settings after upgrade. In case of RAM, if you bought a compatible modules, then they should work without an issue.


If you're using Windows 10, then make sure to have at least BIOS version 2.21 (first will official Windows 10 support).
