Installation on XAMPP - php_memcache.dll

Hi

I am new to PHP. I found this engine and try to get some fun with it.
But there is an problem during installation:
Extension - Memcache Missing
and
PHP Accelerator Not detected

I relay dont know what to do, google said that I should get php_memcache.dll extension, but all available files are corrupt and generates errors.

What serer on localhost you recommend ?

Or maybe I should run PHP 5.2.*, now I have 5.3.1 ?
