what is the Windows Memory Limits for microsoft windows 8?
Long past time to upgrade to 64-bit. It was actually better when I FIRST tried it around 2003, but comparability was off and it was a nightmare to “go back” to 32 bit. Now it is black and white, 64-bit supports the new hardware and 32-bit does not. All 32 bit software can be quickly and painlessly expanded to fit into the 64-bit spaces. Most operations are up to 200% faster except for memory moves being 25% slower but they are obviously finally redundant since we finally using hardware pointers and other methods.
