2500xp with A7S333

[R Miller]

I guess I got confused, but I bought an Athlon 2500xp cpu for my Asus
A7S333 moherboard. I had a little trouble getting it to run out of the box
and emailed Asus. They said don't use it, the motherboard doesn't support
it. Well, I did anyway and got the board to boot up. It really seams that
some boards need to burn in first. The computer works fine, but indentifies
the chip as a 1700xp. I coaxed the board up to 1963 mhz. Anyway, here's the
question. Am I missing out on preformance by using this chip and what's so
different about this chip when the motherboard supports the 2600xp chip?
Thanks in advance.

1700+ (133 x 11)
2500+ (166 x 11)
Notice both chips use the same multiplier. The reporting of the model
numbers by the BIOS seem to be more tied to the multiplier then to the
bus speed, so the BIOS is just guessing and reporting a 1700+, it could
also be the bios was never programmed to display 2500+ if it's pretty
old.

AMD's model numbers are based on the bus speed (and ram used) as well as
the CPU speed, the faster the bus and ram runs the faster the whole
system performs, that's why most tweakers will tell you to push the bus
speed first then play with the CPU multiplier to get the most out of a
system.

The 2500+ default is 1833Mhz , you already have that beat, so on the CPU
side of things you are doing just fine. A lot of guys run these newer
chips in older boards, the worst setup would be putting that CPU on say
an old 100MHz bus board at 100x20 with PC-100 ram, even though the CPU
would be at 2GHz the slow bus and slow ram would make the system as a
whole perform much slower.
