(1) Intel 32-bit Systems in the tables above.
(2) AMD64, Intel EM64T 64-bit Systems in the tables above.
(3) Multi-core and/or hyperthreading CPUs count as a single CPU in the table above.
(4) Update 7 is available as of August 1, 2008
(5) Limit low because the "hugemem" kernel is not available
(6) Update 4 is available as of April, 2010
(7) Unbreakable Enterprise Kernel is available over Oracle Linux 5.5 and up
(8) With latest update level
(9) With Oracle Linux 6 the default kernel is Unbreakable Enterprise Kernel on x86_64 and RHEL compatible kernel with x86 (32-bit). The limits are provided based on that.
(10) AMD64 / Intel64: On those kernels larger memory can be handled with Intel CPUs
