Lenovo X220 Re-add support for 1866Memory possible?

[The Invisible]

Hy,

in former Bios Releases the X220 (with i5 and i7) was able to use the full Speed of 1866 DDR3 Memory. In newer Releases it seems to be capped :-(
Would this be possible to re add this ability? It's a great Performance increase especially for the onboard graphics.
also whitelist removal for wwan Card would be great for the actual bios!

the latest bios is 1.39

thx for your reply!
any Chance to contact serg008? to get an idea about the full Feature list?
would be quite nice if the Memory Timing/Speed lock is disabled.

I just flashed this modified bios on my i5-2520m x220@bios1.28. It looks like the memory (2x8gb) is now working on 1333, for bios1.28 it was 1600mhz.

But I am waiting to replace the wifi card with 7260ac so I guess I have to put up with the slower memory.

thx for your Feedback!
same on my x220 since going higher than 1.28 no more 1866 Support :-(
would be so great to unlock this Feature again :-)
