Hello, so with the option unlocked it might be possible to push the RAM overclock further by changing it from 133 to 100.
For some reason it's hidden on locked CPUs on newer BIOS, but it shouldn't be a problem unlocking since it should work even on the locked CPUs.

The setting is called dram ref clock, that can be switched between 133 and 100.

Here is the website for my motherboard BIOS (latest version 7B18v1B)
