You could also bisect it. I suspect this one:
7bddd30e94 nb/intel/sandybridge/raminit: Allow 933Mhz on Lenovo devices
Though, that could just be because I never agreed to it (it might even not make a difference in your case depending on the used memory modules).
Fixed as of b794a69ce9b2cbb9d6565cf0f3ac609402ad680a.
nb/intel/sandybridge/raminit: Add Kconfig option for fuses
Add a new Kconfig option to ignore memory fuses that limit the
maximum DRAM frequency to be used. The option is disabled by
default and should only enabled by experienced users as it
might decrease system stability or prevent a successful RAM
training.
Remove conflicting devicetree settings.
