Dell Dimension XPS T450 cpu upgrade ?

[HappyGamer2]

I have a dell with a p3-450 katmia cpu, slot 1, secc2, with a intel 440bx agp motherboard, I also have a voodoo5 agp and 192 mb of ram (pc-100, ecc).

The question I have is can I put a p3-800e coppermine slot1 secc2 100 fsb cpu in my system without any major diffuclty? I will have to update my bios. but will i have move jumpers or make some bios setting changes?

I went to the dell website looking for info but didn't get that much details, i emailed them and got a automated response, here is part of it:
6g. Upgrading the CPU on Pentium III-based Dell PCs.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Because the majority of these systems are still shipping, it is difficult to
determine ultimately what maximum speed these systems will support. Newer,
faster speeds are supported, if possible, as Intel releases new processors. It
is recommended that if you wish to upgrade the processor, you first check at
http://support.dell.com to determine the current maximum supported processor for
your system.

I notice there are bios upgrades for coppermines up to 850 at the website.

I also wonder how much performance gain I will get with the cpu upgrade since I still will be at a 100 fsb, This upgarde is mainly for gaming, UT/quake3 etc.

FYI: The BX chipset is famous for having many boards that run 133 bus quite nicely, if your memory and pci cards can take it.

I just got off the phone with dell tech, they said with a bios update the system will take up to a 850e (100 fsb) without any problems. now how do i get it up to 133? just put a 133fsb cpu in? I'm sure my memory won't handle it, it's cruical(micron)brand, but pc-133 ram is cheap now. I have tried to overclock the system, but never got it to work at all.

I'm not familiar with Dell's BIOS, but I'm sure that it won't allow you to just select the FSB. So, unless they actually tell you that a 133 FSB cpu will work, I wouldn't do it.

actually , 850 is the highest released retail p3- 100 mhz bus processor. If you do a search on pricewatch though, you can get a 900 or 1000 in OEM 100fsb versions. With a slot adapter you could have a 1 ghz p3.
