Or- My Computer/Properties/Advanced/Environment Variables if Intel64 or AMD64 is listed next to architecture you have a 64-bit hardware. CPU-Z is a freeware that gathers information on some of the main devices of your system. Typing systeminfo in a CMD prompt will also bring up specifications. The "virtual + physical" can translate to pagefile + RAM.it pays to check. CPU-Z to niewielki i bezpatny program do szczegóowej identyfikacji zainstalowanego w komputerze modelu procesora, pyty gównej, chipsetu, karty graficznej oraz pamici RAM. CPU hardware DEP/NX should ensure full compatibility as well.

One way to find out is look up chipset specifications on Intel ARK. Intel ARK maximum memory specifications are nGB for all 64-bit processors, but for the IA-32 family the " nGB" is replaced with " nbits", e.g. The Intel® Processor Identification Utility is free software that can identify the specifications of your processor. This is where confusion reigns because Technet (and MSDN to lesser extent) imply Windows 64 is required to use over 4 GB of RAM, omitting the part about hardware support. It refers to Windows 64 compatibility, as I remember IA-32e is not supported after 8.1. I would like to point out "64-bit instruction set" as defined by Intel doesn't guarantee a 64-bit CPU.
