Can a standard Version of windows xp pro (32 bit) run on a 64 bit machine

Can a standard Version of windows xp pro (32 bit) run on a 64 bit machine or do you need windows xp 64?

Ive noticed this written while reading about chipsets ie:(AMD ATHLON 64 3500 64BIT VENICE)" 32-bit performance, with readiness for 64-bit applications" Does this mean the chip is 64 bit or still running 32 bit with 64 bit compatibility? Can I use either 64 bit or 32 bit OS (windows) on a 64 bit system. I need a new pc to run sequioa v7.0 with an RME hdsp9652 card (which is not yet 64 bit compatible). So i am wondering if i get a 64 bit system will it work with xp pro 32 bit os.

Ok now ive seen this as well while reading specs on chipsets, ie:(AMD OPTERON DUAL CORE MODEL 270)"SIMULTANEOUS 32 & 64-BIT COMPUTING" Is this the same as ," 32-bit performance, with readiness for 64-bit applications" man is this confusing. Or is this different again. Will a chip,say(AMD OPTERON DUAL CORE MODEL 270)with "SIMULTANEOUS 32 & 64-BIT COMPUTING" run standard xp pro 32 bit os.

I guess you know by now i need to run 32 bit os,so can i do this with full compatability on a 64 bit system using either the AMD ATHLON 64 3500 64BIT VENICE or the AMD OPTERON DUAL CORE MODEL 270. I'm keen to stay with AMD or should I just get say an INTEL 560J BTX - P4 3.6GHz 800FSB LGA775 and just stay 32 bit all the way.

Any ideas greatly appreciated. Am i making sense or have i lost the plot.hmmmmm.
Thanks anyone who can straighten this out for me.

heathen.....
just dont worry. just run win xp 32 bit on the amd platform.
i wont be going for vista anytime soon.
i might bypass vista completely and wait for the next whatever from MS.
way more important is useing a good input signal chain to the daw and convertors imho.
just my 2 cents.........cdn....

Thanks manning,but man Ive got $50,000 worth of gear and I use apogee conversion,sound quality is not what i need to know about. I just want a machine thats compatible with RME hdsp9652 and sequoia 7.0. All I need to know is if windows XP 32 bit os will run on a 64 bit machine. This answer is proving difficult to obtain. But from what I gather now this is possible,I'll talk to the guys building the thing.Just trying to convince a bunch of gamers that I still need 32 bit os to run my studio draws a look of blank faces,going um duh um. Thats cool they'll sort it today.

[manning1]

yes...vanilla xp will run on these amd processors.
thousands and thousands/millions are doing it.
you dont have to get vista to run amd 64.
all it means is the user can choose whether to run current xp or
the new vista.
read THIS.....noting third para after key element...
about intalling even win 98....

Thanks Manning now I'm straight on that. Cheers. I just did'nt get it when you said "Vanilla" and "Vista" Ive never heard them called that.
Cheers.

I can tell you from experience that you can easily run 32 bit XP pro on a 64 bit processor. Runs just fine it just doesnt (for obvious reasons) take any advantage of the 64 bit processor.

I seem to recall Windows XP Pro (as opposed to Home) being required for dual processors.

How about dual CORE, as in an AMD X2? Is Windows XP Professional required, or will Home also work?

[manning1]

you can run any dam thing you want ..even on a amd dual core.
if in doubt contact amd tech support.
you can even run oddball OS's.....non linux/non windows.....
providing the OS adheres to the architecture.
you could run windows, linux oddball OS's...it DONT MATTER.
as long as the OS developer has adhered to the rules of the underlying architecture in building the OS.
you could even program YOUR OWN OS useing assembler if you wanted ....
and it would work providing you adhered to the hardware architecture.
if you peruse various OS developer forums (via google).....lots of folks are
building their own OS for fun or whatever.

its my understanding when running an amd dual core on vanilla xp.....and lets say one has this monster mixdown .....what happens if one processor is maxing out is that xp rebalances load so kicking in the second processor.
in the biz this is called load sharing.

simply put even the crummiest application will prolly run smoother under dual core architecture than a single. but its prolly wise to mention you would only notice
a difference if it was a processor/disc intensive application.
but best way is to run tests...if your doubtfull like ive done.
i noticed a definite speed up when i tested the software in my sig on a dual core.
in fact ran like a bunny wabbit on steroids.
at higher processing counts i noticed everything was smoother on a dual core.
lighning faster edits, batch effects processes ran faster etc etc.
the time displays ran smoother ..whereas on low power pc's they would start sticking of course once load got high.
for example lets say you got this old biz app that accesses a database of a gazillion customer records and sorts them into some sort of report.
i suspect the dual amd will do this faster running old code than a single processor.
certainly from my tests anyway.

Manning1 is absolutely correct. In fact, Dual Core performs better than dual processor. Plus, it doesn't require the degree of good code to utilize fully like dual processor geared code. I've seen tet after test showing near 1:1 scaling. Dual processor usually is more like 1:3, sometimes 1:2... typically.


Of course, it would be nice if more hardware and software would start embracing 64 bit OS, but we just have to wait until XP is "old" enough to disregard.
