I followed the instructions from the wiki and after finishing the instructions I found another set of work around instructions for dealing with x86_64. I did not compile them myself I used yum to fetch them from the openvz repository.

there is no 4GB limit on x86-64, so the whole RAM will be used.
there is a note in wiki
Note: When using a 64-bit processor and operating system, you need only select the SMP or non-SMP version. 64-bit linux can access the entire 64Gb of ram in ZONE_NORMAL (low memory). PAE and 4GB/4GB splitting are only needed for 32-bit OS, and so are not necessary and are disabled by default in 64-bit kernels.
And I've also added the table in question is i686-specific.
Sorry for the confusion :/
