Ivy Bridge doesn't support 16GB DIMMs either. I've opened a ticket before. https://ticket.coreboot.org/issues/56

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
