N450 Overclocking w. SetFSB Auto tool

Hi guys,
I need your help setting the OC on my N450 using the SetFSB Auto tool (please no comments on senselessness or futility, thank you).

After installing the tool on my Asus 1005P I've followed the following steps:
1. I've manually OCed using the SetFSB tool to where the PC was stable @2Ghz.
2. I've configured the Auto tool by setting stock clock speed at 1667Mhz (at a later try 1660Mhz), Max multiplier at 10 and desired OC speed at 1800Mhz, using the PPL : ICS9LPR427AGLF.
3. Result is PC freezing.

What am I doing wrong?
Thanks in advance.
