Does the CentOS have /proc/config.gz or /boot/config-`uname -r` ?  If 
so, grep for MEM in there.  If HIGHMEM4G is already set, you could try 
setting HIGHMEM64G instead.  It looks like 64G sets the PAE parameter.  
Don't know if it will slow things down.  You can also try booting with 
kernel parameter mem= and then something like 4G or more likely 
mem=4096M.  It looks like you need a kernel with HIGHMEM64G.
