32-Bit vs. 64-Bit CentOS Server configuration with 8 GB RAM

  • 772

Looking at Xeon E3-1230 system with 8 GB DDR3 RAM.

I've read (somewhere) that Cent OS 64 Bit has problems and/or that the 32 bit version is "better".

Also, I know that with windows you need 64-bit in order to use higher amounts of RAM, but I don't know if that applies here.

Thanks

    I am not aware of any issues with the 64 bit version.

    It's a 64 bit CPU, so I would definitely run 64 bit. I have been on hundreds of servers with 64 bit CentOS and never experienced any strange issues related to the fact, that it is a 64 bit OS.

    Also, you cannot allocate more than 4 GB of RAM with 32 bit.

    So to sum it up; go 64 bit.
