Hi everyone, I tested the installation package of US version 8.3.1 on Windows Web Server 2008 R2 on x64 machine. I found that the httpd and mysqld services are both 32 bit programs, so I think the server will not be able to use more than 4 GB of RAM. Please correct me if I am wrong. I am continuing with WAMP Server as they support 64 bit architecture so I can use more than 4 GB RAM in my server. Any sharing of insight is appreciated. Thanks
