if u have a 64bit computer can u still use 32 bit stuff?

jasonchiu · April 12th, 2005, 2:43 PM

a boy name andrew hui told me that if u get a AMD 64bit computer u cant use the 32 bit stuff. i dont belive this, thats so stupid.

what is the truth

Kip_6666 · April 12th, 2005, 2:46 PM

depends what he means with a 64bit computer.

The stuff we buy, athlon 64's and the 64bit enabled p4s work fine in 32bit mode.

Hes full of shit, kill his parents jason. images/smilies/smile.gif

andyhui01 · April 12th, 2005, 2:49 PM

first off all... do some google research... I just said for 64bit CPU, you need a 64-bit OS.... according to this article http://www.unisysworld.com/monthly/art.php/273 ... Microsoft says you need some software to make it backwards compatible

jasonchiu · April 12th, 2005, 2:54 PM

U FULL OF SHIT BOY. I KIIIIIIIIILL U. i knew it, why would some company to be that stupid to make a new product that can use the old uber popular stuff.

yeah so, even if a program is 32bit, u can still use it on a AMD 64bit computer right?

ANDREW BURRRRRRRNNNNNN

Kip_6666 · April 12th, 2005, 2:57 PM

Well, it depends on the os. If your running a 32bit os on one of the 64bit cpu's i mentioned above you can't run a 64bit program.

Not sure if it works the other way though, if your running a 64bit os on a 64bit cpu, and want to run a 32bit program.

I do remember u could run 16bit programs on a 32bit os.

andyhui01 · April 12th, 2005, 3:05 PM

when it was first launched... I read somewhere that it wasn't backward compatible... I haven't really read alot about tech stuff lately... just been hanging around on this forum on my free internet time images/smilies/lol.gif

jasonchiu · April 12th, 2005, 3:12 PM

yeah so if i purchased a 64bit computer i can run all the old stuff as old as i havea 64bit OS right.

i was saying to andy that i would get a new pc when i go to uni since this one has cuased me so much prblems and he tole me that the stuff i have now wont work, which i thoguht was BS. images/smilies/bangin.gif

andyhui01 · April 12th, 2005, 3:15 PM

I said you can't use the regular Windows XP... you have to use the 64-bit edition... stop making up BS and do some google research on your own

EDIT: I just did abit of googling and I think that AMD 64-bits are fully backwards compatible, however the Intel 64-bits kind of backward compatible, but it is very slow and unreliable with alot of bugs

Kip_6666 · April 12th, 2005, 3:28 PM

Its easier to see them as 32bit cpus, with an extra instruction set to run 64 bit os's and programs.

The above cpu's can run 32bit stuff just as well as any other 32bit cpu.

thats how AMD made their 64-bit.... but not intel with their Itanium2, but I'm pretty far behind in technology these days, too lazy to catch up with it, moving too fast images/smilies/lol.gif

swek · April 12th, 2005, 3:40 PM

I have a AMD 64 and so for my trusty old 32 bit Windows XP seems to run fine. images/smilies/lol.gif

The only weird thing I discovered was that I couldn't install the XP 64 bit edition. My computer always gave me some crytic error. What's up with that ?

jasonchiu · April 12th, 2005, 4:06 PM

^ lol wtf?! i doubt u paid for your 64 bit edition or else u be uber pissed off writing that

swek · April 12th, 2005, 4:08 PM

No, it was the demo edition. I'm going to be pissed if this should happen in the final version.

chaos386 · April 12th, 2005, 5:10 PM

I'm running an AMD 64 bit CPU on 32 bit Windows XP just fine. When Windows XP 64bit edition is released, you'll be able to run 32bit apps and 64bit apps, but not 16bit ones. There should be a small speed boost for 64bit CPUs as well because of the 64bit drivers.

freerider · April 12th, 2005, 6:29 PM

You CAN run winxp 32bit (or any other 32 bit os) with an Athlon 64. But only with the Athlon 64. But you wont get full advantage of the 64bit technology. Currently I'm running xp 32 bit and 64 bit for experimenting(free and demo).
Don't ask which is faster bc, the 32 bit version is more used and more things are installed, so it's slower. But I think that the 64 bit is faster when clean installed vs 32 bit clean install. But keep in mind that the os isn't everything. You also need 64 bit applications to take full advantage.

i'm sorry but you were wrong
i think from what i read and undertand you say that if you have a Athlon 64 (64 bit cpu) or 64 bit intel (600 series) runing windows 64 you can not run any 32 bit programs. this is false

running 64 bit cpu you can run a 32 os and 32 bit programs
running 64 bit cpu you can run a 32 os and 64 bit programs
running 64 bit cpu you can run a 64 os and 32 bit programs
running 64 bit cpu you can run a 64 os and 64 bit programs

from what i have read this is how it will work

chaos386 · April 12th, 2005, 7:31 PM

I should also add that all of the new CPUs from AMD and Intel are 64 bit. Intel added AMD's 64bit extensions onto their Prescott core (all new Pentium 4s) a while ago. The only 64bit processors that won't run 32bit are Intel's server-only Itanium chips.

I should have the non-release candidate version by the end of the week. Right now I have media but no key for an activated copy, and a key but no media for a volume licensed copy. images/smilies/sad.gif

Microsoft should be sending us the media and key that we are lacking shortly hopefully, but it seems to be taking them forever, mostly because I want a copy for my new A64 machine images/smilies/biggrin.gif

But to answer the original question, yes A64 chips and machines can run 32bit applications. Itanium2 sucks, period.

anyhow, "running 64 bit cpu you can run a 32 os and 64 bit programs" aint gonna work.

[root@xxx ~]# uname -a
Linux xxx.yyy.zzz 2.6.11-1.1226_FC4 #1 Mon Apr 4 20:55:33 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux

[root@xxx ~]# cat /proc/cpuinfo |grep name
model name : AMD Athlon(tm) 64 Processor 3200+

Runs fine on Linux for both the x86_64 packages and (if I need to) the i386 32 bit packages. This is one of the earlier ones, from Dec 2003 I think. Haven't tried it on Windows, but all of the Athlon64's at least will run just fine on both 32 and 64bit.

The Itanium from Intel and Opteron(?) from AMD, are however "real" 64bit CPU, so they will only work with 64bit OS'es and applications (or that is, compiled for 64bit). Those two models are meant mostly for servers, though.
