Apparently since BIOS version 1.29, the X220 cannot run high speed memory above 1333MHz. Meaning that JEDEC approved SODIMMs that can run at 1600 & 1866MHz are stuck running at 1333MHz with no option anywhere in the BIOS to force higher speed.
The last BIOS to support high speed memory was 1.28.
The question is, why did Lenovo see fit to remove this useful feature? Is this a bug or was this feature removal intentional? Are there plans to restore this feature in future BIOS revisions?
Thanks in advance
