RAM question

[PotsOn]

No, 64 bit XP was available shortly after 64 bit systems appeared also.

Linux came out with 64-bit OS in 2001 and was the first OS to run on Intel's
64-bit processor.

A year later Microsoft released Windows XP 64-bit Edition.

Cheers.

What exactly do you mean "now that true 64 bit hardware and OSes are
here"? I was using Tru64 Unix on a DEC Alpha 10 years ago!!

Got you beat, 13 for me.

Microsoft Windows, I think is the last OS (server or desktop) to be 64 bit.
Hardly new is right. Actually has be around since the '60s.

Funny how you could buy a system with XP 64, but cannot buy the OS.....

You're right, he does say he's running 64-bit Vista. I wonder what
happened, in that case, to show 3.3GB even though he had 4GB
installed? Maybe it shares RAM with the video system, so even though
there's 4GB installed it sees 3.3GB as system RAM and the other .7 as
video RAM. Sounds odd to me.

It is possible 64 bit has the same limitations as does 32 bit, if the
hardware was the limitation. I am not sure if there are motherboard out
there that do this, but if they motherboard hardware had the 4GB limitation
then it too would behave like 32 bits even if 64 bit OS was loaded.
