Ignore the mainboard's vendor programmed fuses that might limit the
maximum DRAM frequency. By selecting this option the fuses will be
ignored and the only limits on DRAM frequency are set by RAM's SPD and
hard fuses in southbridge's clockgen.
Disabled by default as it might causes system instability.
Handle with care!
