Noob question

I think the ability to run a 64 bit os only depends on the cpu and not the motherboard.

thanks for your reply, however there is a notice on the intel site and cpu box that says:


"64-bit computing on Intel® architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel® 64 architecture. Processors will not operate (including 32-bit operation) without an Intel 64 architecture-enabled BIOS. Performance will vary depending on your hardware and software configurations. Consult with your system vendor for more information."

chipset and bios = motherboard right?

if i may rephrase the question:

how can i know if a motherboard chipset/BIOS supports 64 bit?

Thanks again!!

Everything needs to be 64 bit: hardware and software. Hardware is simple. Every Intel Core2 CPU, compatible chipset and BIOS, and mainstream motherboard supports 64 bits.

Software is a little more complex. You need a 64 bit OS and you need 64 bit device drivers. If you have an old piece of hardware with no 64 bit drivers available, you will not be able to use that hardware.

ok i got it.

so if a motherboard supports core 2 duo then it will support both 32 and 64 bit computing.

Thanks guys!!!
