It would be really great if you could test out a Core i7-3840QM in the G2 socket of the Thinkpad T520. Its the best ivy bridge with 45W TDP and the Core i7-3840QM officialy support 32GB of RAM.

The Lenovo OEM Bios wont support ivy bridge. Coreboot didnt have such limitations ;)

Thanks!

I see.

Thank your for your time to explain. Seems like I have to look for a  
new laptop then ;-).

It was a fun project, I learned a lot and I'm really impressed by the  
usability. Will definitely keep coreboot on the t520!

Best,

Thomas
