I have a AMD XP2100 1.7G MHZ Socket A installed on the AV7V333. May I
upgrade the CPU to a faster speed.
Any recombination?
Thanks, Dave

According to that list, it looks like you need a PCB board revision
number of 2.00 to run at FSB333. The PCB revision number is usually
printed in white numbers and should be near where the model number
is printed on the motherboard. I also think there was a sticker
somewhere on the packaging of the motherboards that were FSB333
ready.
Another option is the AthlonXP-M processors, which are multiplier
unlocked. You need a motherboard that can set the multiplier
to use one of those, and have to do some research on your
motherboard first, to see if anyone has done it before. I use
one of those mobile processors at 200x11 on my A7N8X-E Deluxe.
If your motherboard is limited to FSB266, you could aim for
133x16.5 to get to 2200MHz. (These processors were available
at Newegg and there might still be some for sale.)
This web page has info on available multipliers. The multiplier
is a five bit code, and on many motherboards, a chip drives four
of the bits, under BIOS control. To get multipliers 13x and
higher, requires controlling the fifth bit, by using a wire
stuffed in the S462 socket.

When doing multiplier testing, you drop the clock to 100MHz,
in order to avoid driving the processor to too high a speed.
Once you figure out how the multipliers work, you can move
back to 133MHz. If your motherboard is rated at 166Mhz, then
166x13 would still require the wire trick in the socket.
Accepting 166x12.5 = 2075MHz would not need a wire in the
socket.
Here is a picture of a wire trick. A tiny wire which is tinned
on the outside is best, as bare copper can oxidize.

If you select "socket view" here, and try the various multiplier
values, you can see the difference in the jumpers, between less
than or equal to 12.5 and the 13 and above multipliers. Four
of those bits can be driven by a chip on the motherboard, leaving
only one that needs a wire.

In some cases, a software program can be used to load the multiplier
into the MSR, allowing overclocking from within Windows. That
program only works with mobile processors, but also requires a
lucky motherboard to work. That program doesn't work with my
A7N8X-E.
