Cityscape: Because 64 does want more RAM.
BC_Programmer: No. It doesn't.

Microsoft KB: It has more memory overhead.

You know what, they are both right. I just checked. as has been stated, handles are now 64-bits.

My PC currently has, in total, 4,097 open handles.

if those handles were 32-bit, they would consume 4,097*4 bytes=  8194 bytes.

But... It's horrible! AWFUL!

because that is totally inaccurate! Only 2,570 if those handles are in fact 32-bit! that leaves a whopping  1,527 handles that are actually 64-bit. Oh the HORRORS!

so those 1,527 handles each use 4 extra bytes, so while if my PC was 32-bit I would have a "overhead" of 8194 bytes, I now have to deal with the crushing truth that, because of my huge mistake in choosing 64-bit, I now have to live with the awful knowledge that I am wasting a whopping  6108 bytes of storage!

DEAR GAWD! This is HORRIBLE! How could somebody with only 2GB of RAM POSSIBLY spare that much RAM! Nope, they should stick with 32-bit.

Don't know how I can go on, knowing that I have that wasted 6,108 bytes of storage simply because I have an x64 OS. Sure, I can access >4GB of RAM, but it's the principle of the thing. I'm going to by crying myself to sleep over this for weeks.


oh, and by the way, that was thick sarcasm. I thought I'd mention that before anybody started recommending therapists.
I was trying to dereference Null Pointers before it was cool.

You may still need a therapist.
Did you know that the Intel X64 specification does indicate that pointers and other memory references are 64 bit when the system wants to use more the the possible 4GB range available in 32 bit. Yes you know that.
But now for the ugly details.
Only 56 of the 64 bits can actually work! They cut off 8 bits that should have gone into the hyperspace. Instead, the unwanted bits are lost inside the CPU, falling into a virtual black hole. What a waste! Just think of it! every 64 bit handle, procedure call, or data tree calculated as 64 bits, but only 56 are available.
[dark sarcasm]
Those wasted 8  bits could have been donated to old-timers still using CP/M and treasure every extra tasty 8 bits can get.

The subject of question is very important .
After these discussions. Wish summarize it. I mean, define general requirements for 64-bit system ???

Suitable hardware. That's it. Google is your friend.

Energy = mass * velocity squared? what backwards physics classes have you been taking?

The ones about kinetic energy, but she took the classes twice?
