Help me out with this please. You may wish you had a dollar for each time
you answered this, but I can't find your post.

I have read the ASUS CPU list, and know what the limit is there, but would
like to see if an XP rated higher than 2600/266 runs without problems. I
would like to run a 333MHz FSB CPU if possible.

There have been reports of success in doing this, but the only way to
find out if it will work for you is to test it.

What happens if you buy a 333MHz CPU and it doesn't work, can you throttle
it back to 266.

I can throttle back my "XP 1800+" from its default 133 MHz back to 100
MHz either in software in the BIOS or in hardware with the DIP-switch on
the motherboard. So you should be able to throttle a 166 MHz CPU's (so
called 333 MHz Bartons) back the same ways me thinks.

The question becomes if there then will be any significant performance
gain if you have to to this.

In BIOS setup you can change the CPU-bus 166, 133 & 100 MHz. With the
DIP-switches on the motherboard you also have the intermediary 150 & 140
MHz to choose from so you don't have to throttle down all the way to 133
MHz, hopefully.

I called AMD and asked the same thing because of the difficult to find
2600+ 266MHz FSB (OEM ONLY) CPU. Which happens to be the fastest CPU
I can put in my (NON-OEM) A7V333 rev. 1.04 MB. I was thinking on
using the 333MHz version and throttling it back. AMD Tech Support
gave the following example:

---Example below is same CPU with locked Multiplier---

Model | FSB x2 | Multiplier | Clock Freq.
----------------|------------------|------------------|---------------------
2600+ | 166 333 | 12.5 | 2080
---------------|-------------------|------------------|---------------------
2600+ | 133 266 | 12.5 | 1670
----------------------------------------------------------------------------
As you can see in throttling it back you'll decrease the FSB but in
so doing you'll also reduce it's core clock.

In the case above you'd do better off with a 2400+

P Rating | FSB | x2 | Multiplier | Clock Freq.
----------------|----------|--------|------------------|---------------------
2400+ | 133 | 266 | 15 | 2000
----------------------------------------------------------------------------

Which is what I've done. I'd rather use a (NEW RETAIL) 2400+ @
2000MHz 266MHz FSB (3 year Warranty) in my A7V333 rev.1.04 than to
either throttle back a (NEW) 2600+ 333MHz FSB to 1670MHz/266MHz, or to
wait until I find the rare 2600+ 266MHz FSB (OEM Only), (30 day
warrantee at best) (no guarantee that it's not a pull) CPU.

Of course if I ever come across a really cheap 2600+ 266FSB CPU say
for $10.00 then I'll gladly swap it out. ;-)
