Will the ThinkPad X220 support 16GB of RAM?

I have an X220 and while back when Windows 7 was around 4GB sticks were already very expensive. Today 8GB sticks are readily avialable.

So Intel says the chipset does support 16GB so can I install a pair of 8GB sticks in my X220 and be able to perk up performance?

My rig has an i5-2520M CPU and I am using x64 Windows so I can leverage more memory

The BIOS is UEFI so I can use a larger capacity SSD too
