Why is 64buts better? And what is the right hardware for that type of OS?!?

i have 0 exp. with 64bit OSs. i don't know why its better than aside from the fact it allows you to use more RAM.

and as for hardware... ummm a 64bit processor and 4 Gigs or more of RAM.

you will also want a nail gun to end your life after endless bugs

It also makes a large impact upon applications that run on that bit environment.

Simple example....on 32-bit a normal size integer ( word ) can store a maximum number of 2^32 - 1 for an unsigned integer ( about 4 billion), hence the 4gb addressable memory limit, or 2^31-1 for a signed integer ( about ±2 billion) ..on 64-bit, it can store 2^64 - 1 ( about 18,446,744,073 billion ) for an unsigned integer, or 2^63 - 1 for a signed integer ( about ±9,223,372,036 billion ). This means all calculations can store much for precision for Floating point ( decimal ) numbers as well, so you can do math out to more decimal places.

It also means in the same amount of clock cycles, you can do math on much bigger numbers than you previously could on 32-bit processors, i.e.you could multiply 18,446,744,073 Billion * 18,446,744,073 Billion in about the same time you could previously multiply 4.096 Billion * 4.096 Billion. But note this does not make all math faster. It still takes the same amount of time to multiple 1 * 1 as it did in a 32-bit processor ( theoretically even a little more since it takes longer to read/write the extra 32-bits from memory before/after the operation).

But it doesn't make a difference unless the application you are running is modified to utilize64-bit architecture, and will run into possible difficulties if it doesn't. The major issues lies within COM components, in which 32-bit COM components absolutely DO NOT WORK with 64-bit applications. That means all COM components have to be re-compiled under a 64-bit environment and retested before it could ever work under 64-bit.

I'd guess another application favoring 64 bit OSes would be code and password breaking?

well it seems illogic that writing the extra 32bits thus make it slower, but ppl says that 64bits is faster...

Somebody tell me what's better before I go installing the wrong OS. I have both 32bit and 64bit to choose from when I am ready to install.

64 bits allows you to install much more RAM when using Vista. But you may run into some driver problems, if they haven't got 64-bit versions. That's how I understand it.

64bit is the future. Either the problem with it will be ironed out, or the apps will be left behind, as so many did when XP became the way.

Do both and then find out for urself

Oh, I'm talking about XP by the way, not vista.

Oh. Why are you installing XP? Vista isn't terrible, and hopefully your new rig will have enough juice to run it well? I still think 64-bit is the way to go, though you might want to wait for Meph and Anomaly to weigh in.

Farmchild · « **Reply #12 on:** August 21, 2008, 09:53:39 am »

IMO XP 64-bit is buggy. If it were vista, I'd say 64-bit all the way.

ehh, don't wait for me on that one man.

<------ 64bit n00b

i know my way around Xp 32bit pretty well but ive only had hands on with Vista 32bit for maybe 30 min and have 0 exp. with 64bit on any OS....

im more of a hardware nerd than a software one.

From what i understand - i have never tried it myself - XP's 64bit version is more trouble than its worth. If you are intent on doing it, make sure that all of your hardware has 64bit drivers and your favorite software has 64bit versions before taking the plunge.
