I want to know if there's any way to use the Athlon 64 processor to a greater degree in regular Windows XP. I don't want to use XPx64 bcz of compat. issues with a lot of programs.


Anyone have any suggestions?

Not that I know of. I got a 64 bit and It works fine. No need to want more in a regular Windows.

If you think about it.
Win XP came out before 64 bit processers
so how could there be 64 bit optimised code "locked up" in XP

well there might be some features that can be tweaked to allow the processor to use more of its potential. For example, you could be able to change something that sends more processes to be executed at once or something (im just guessing here)

Also remember that 64-bit wasn't completley unheard of when xp came out.

Probably isn't. That's why they're building XP x64. Why don't you just use a open source OS that's 64 bit?

No, there isn't as far as I know of. I'm going to install the 64bit edition later today just to give it a bit of a go. Basically the reason is because the whole 64bit archiecture is different, the way things are done in the CPU and stuff and Windows doesn't support that natively..

I seemed in some place that Windows just realeased a version compatible with 64bits-Processor.

Well, im not sure its released

It's free to try..

there is no way to "tweak" a normal windows to operate in a 64 bit manner unless you have win xp 64bit. Its not about sending more processes to the "cpu". 64bit to my knownledge still only has one ALU, which means its can only handle one process at a time. Normal xp only sends out 32 bits of information at a time (hense why its a 32 bit os). you can't tweak it to send out 64 bits of information cause the os just wont know whats happening. So basicly you have to get xp 64bit for it to have any effect on speed and what not. Although 32bit xp will still function, you wont see much of a speed difference.

I don't know whether of not it would be of any benefit running a Linux Kernel in the background and then loading windows XP through VMware or something.  Perhaps this could give more processing potential although I'm not entirely sure how 64 bit chips work

athlons typically run faster than p4's cause of how their cache is set up. like for example. an amd 1 ghz is probably equal to a 1.4 p4.. but thats just throwing out an example, i have nothing ot actually back that up on

also .. xp 32 bit can not send 64 bits through the system bus.. its impossible. its not desgined to work as a 64 bit OS

I am running standard XP and I do notice a speed difference. My 3500+ out-performs my friend's P4 3.7 Ghz.
