  The key differences from the classic Unlock Turbo Boost:

- The PEI driver version supports sleep, i.e. after sleeping the unlock is not removed as it was in other unlock drivers before.
* The PEI version of the driver often kicks off brand-name boards (Asus, MSI, Gigabyte, etc.), if you want to keep the unlock after sleep, use RAW.
- The DXE version supports dual-processor systems, but no sleep, also DXE version supports individual unlock for each CPU.

• This instruction fits any LGA 2011-3 motherboard, including branded ones like Asus, MSI, Gigabyte etc. Before you do Unlock, make sure your CPU is Stepping 2 or the final version. It is not recommended to do Unlock if you are using an E5-16xx v3 processor with an unlocked multiplier, the system will behave extremely unstable.
