This is so strange, the module is clearly inside that directory. When I used that directory in file explorer, it found the module. I think it's compatibility issue ? rather than not found ?
I got that dll from here http://windows.php.net/downloads/pecl/releases/imagick/3.4.1/
Okay, after reading this article, I realized I lack one step of below, I thought, i just have to copy the php_imagick.dll to the ext directory.
copy CORE_RL_* file move into C:\xampp\apache\bin
