memory_limit doesn't work (no replies)

Hi
I have got EasyPHP 14.1 version, installed on the windows 7 64 bit.
Problem is that, the statement memory_limit doesn't work.
I tried set:
1. directly to script ini_set("memory_limit", "1024M");
2. value in the php.ini
3. value in the .htaccess
4. value ThreadStackSize in httpd.conf
5. value RLimitMEM

I am still getting fatal error. Out of memory. I have still available only 160 mega.
When I set memory_limit less, for example 32 M. Realy I have onlu 32M, but If I want to have more then 160 M it is not possible. Please help me somebody :)
