Actually, AMD Athlon is EV6 is _physically_ capable of 40-bit addressing. _All_ Athlons are Intel 36-bit Processor Address Extensions (PAE) capable too for up to 64GiB. Unfortunately, most physical Athlon platforms (short of select hacks for AMD762/MP[X] mainboards) only support 4GiB or less.
But this is not recommended because there is huge performance penalty from using over 4GB of RAM on 32-bit systems. (enabling PAE) - better way is to use AMD64 instructions.
Exactomundo. In actuality, I do _not_ recommend more than 1GiB on x86. And I still can_not_ bring myself to recommend Xeon IA-32e (aka EM64T) because of its lack of even a basic I/O MMU. But that goes to the heart of Intel's yesteryear design that encompasses concepts of system interconnect. -- Bryan J.
