So whats the deal do i need to reinstalll windows xp to take advantage of my xp 1700. I had a 1.1 tbird in the board and I just changed the processor so do I need to reinstall now. Do I have to wipe the Hard drive or can I jest reinstall
I guess the thing to do would be to back everything up & do a clean install of the OS. You really do not want to just reinstall over:beer:

hey newdragon, welcome to the forums.
Yes, you're supposed to have to reinstall windows to get the benefits of SSE in your xp processor.
Re-installing windows without formatting will not leave all your programs and stuff installed. You will still need to go back and re-install programs, and update windows, etc.
also, this is an unproven theory (at least as far as I know), but I will test this as soon as I can get my hands on my upcomping XP's. You can make windows redetect all hardware by various ways, which I believe MIGHT save people the hassle of re-installing windows.
one way is by deleting a specific key in the registry. another is to disable (or enable) ACPI.
one of my first plans upon getting my new xp processors will be to test this theory out to see if it works or not.
someone pipe up and let us know if you have tried with/without success to do this.
I have also read that you can enable it in wcpuid. It might be good to install the OS again anyways. Ahh the feeling of a freshly installed OS with a new chip. :burn: And about the program thing, I have a question. Do the programs that can use sse instructions need to be reinstalled to take advantage? Good luck and welcome to the forums.

Thanks alot I was just trying to get the best info I can get, to make sure it would actually help before I spent the time reinstallling everything. Thanks everyone.
Hey, I have a program called RegCleaner..it has the option to reset the complete hardware profile in windows.
Tools> Reset Hardware Config
why don't you just do a repair on the system with the XP install CD? Would that work?

Didn't even know the xp chips had sse and I just upgraded today to an xp. Do you have to have certain motherboards to use this?

SSE is a set of instructions for software that supports it
therefore it doesnt matter what motherboard no.
:)
I wouldn't reinstall, I would fdisk, do a FULL format, then install Windows from scratch.

I just upgraded from a TB1.2 to an XP1800
I did not re-install the OS and CPUid shows SSE as enabled.
Is that a true reading?
The 1.2 was at 1.53- same as 1800 - I see little difference in performance.
:eh?:

I intalled a 1600+ in one of my rigs without reinstalling windows and WCPUID also shows SSE as enabled.
I wonder if its really enabled...
*edit*
Never mind I looked int he tweaks for Athlon 4 SSE control and it was infact disabled.
Seems like you should reformat or even re-fdisk to be sure guys!

I planned on it when I know which rig the XP will stay in.

Well last night I formatted and re-installed XP pro from scratch...
The benchmarks and results were basically the same and SSE shows as it did previously: enabled
Personally I would not waste your time re-installing a PnP OS to get the added "benefits" of a new XP chip...I already had them without the 3 hours of hassle
