64 bit windows 2008 r2 installed the 32 bit mySQL? (1 reply)

hi, experts:

I have a 64 bit server, but when i try to configure the innodb_buffer_pool_size over 2 GB, throw error like:
InnoDB: Error: cannot allocate 2621456384 bytes of
InnoDB: Note that in most 32-bit computers the process
InnoDB: memory space is limited to 2 GB or 4 GB.


i check the version:

mysql> show variables like '%version%';
+-------------------------+------------------------------+
| Variable_name | Value |
+-------------------------+------------------------------+
| protocol_version | 10 |
| version | 5.1.53-community-log |
| version_comment | MySQL Community Server (GPL) |
| version_compile_machine | ia32 |
| version_compile_os | Win32 |
+-------------------------+------------------------------+
5 rows in set (0.00 sec)


why can be like this ya? how to upgrade to 64 bit mySQL? thanks
