Winxp64 beta

How many here are using the winxp 64 beta???

Is it worth installing yet??? or is it still lagging behind the 32 bit counterpart?

I have yet to install it and plan to very soon, but it is supposed to benefit nearly all applications, even those that are still 32 bit. It is also supposed to help CAD applications. But again, I never had the chance to tinker with it so I dont know from experience how it is. Get back to me next week if you want to find out.

i assume you're using an AMD64 procesor or an Itanium? or are you gonna try it on a normal 32 bit procesor????

As far as I understand it - Itanium is not X86-64 compatible. The only Processors which support Windows 64 is the Athlon 64/Opteron range and the 64-bit enabled Prescott cores.

I doubt whether you'd see ANY measurable performance difference between the two operating systems - except in rare cases where there's been a rebuild of the software to support 64-bits. Encryption programs, some photoshop functions and that's about it.

It's a common misconception that "64 bits is faster than 23 bits". What it *does* mean is X Terabytes of addressable RAM, and a higher accuracy in floating point math, requiring less bytes for the processing as long numbers are NOT split into 2 or more bytes.

I suspect also, that many peripherals will fail to work with Windows64 Beta due to a lack of 64-bit compatible drivers.

What, theres someone in the world that has a desktop based on the failure that was IA64?

XP64 supposedly has some stuff optimised for AMD64. When I get around to building a system based on AMD64, I'll probably run linux on it. Been 64 bit optimized for years.

yes, my processor is an anthlon 64....i dont believe win64 will even load if you try installing it on a 32bit processor.

I've found most of the device drivers i need to run it except for my raid controller.... i cant load it till i find that one(unless i take my raid config apart).
