Hi,

I have currently a system on a ASUS P4S8x-x motherboard maximum FSB
533Mz. I have 1GB RAM and a P4 2.4Gz (Northwood) processor
(overclocked to 2.7Gz) with WinXP Professional. I want to upgrade my
processor to a Pentium 4 (Prescott) 2.8Gz with FSB 800Mz.

What are the implications of using a higher FSB speed on this
motherboard? Which is the fastest Processor can I use on the same
motherboard or best processor that I can safely overclock the most?

Thanks!

Regards,
Derek

I couldn't find that exact model name on Asus' website, but they do
have a P4S8X-MX. Their CPU support page is here:

From that page, the P4 2.8E GHz processor (Prescott 800MT/s bus speed)
that you're looking for is indeed supported.

Uhh, it'll be faster? You'll probably want to make sure that you're
using DDR400/PC3200 memory for this to work at it's best. It's also
unlikely to be much of an upgrade, so unless your getting a really
good deal on the chip I would personally recommend saving up for a bit
and getting a much larger upgrade sometime down the line.

Not really my forte, but I would tend to guess that you would be
better off with a slower bus speed processor for overclocking. Since
P4 chips are multiplier locked you will need to overclock the bus
speed to bump it up. If you're starting at 800MT/s bus speeds then
you probably don't have much room on this board. it's unlikely to
support much more than about 850MT/s bus speeds, giving you a core
clock of just shy of 3.0GHz.

I could be wrong though, as I said, overclocking (especially Intel
chips) isn't really my forte.
 
Thanks Tony. I think I will go for the Northwood (Everyone says the
Prescott overheats) P4 2.8Mz with 533FSB as you suggested. I already
have 2DIMM's of 512MB each DDR400 RAM.

Why bother. You'll not notice any difference in performance.
 
I thought I would overclock it to 3.2Gz. My current processor only
goes up to 2.7Gz, therefore, an increase of 0.50Gz (nearly 20%
performance gain).

What do you think?

I think your real performance gain would be more like 10% (you can't
just divide clock frequencies) and that even 20% would not be a
noticeable improvement.

Unless your applications are quite CPU-limited, I suspect that you'll
find the increase to be rather ho-hum (if you even notice it at all),
particularly when you look at the ~$200 price tag that the chip
carries. Most applications will probably see less than a 10% boost in
performance, which normally isn't really even perceptible, let alone a
worthwhile upgrade.
