As seen above, I have a dinosaurus.. A7V133-C (1.05.) , Bios 1009

I'd like to update the Athlon 1.2GHz (Thunderbird) with something
speedier...
What can it handle (without ANY modding)? On AMD support pages it says
XP2100 + (Palomino)
But you can't get that either..

Due to lack of funds, I can't upgrade the whole system (MB, CPU and RAM)

A search in Google, suggests looking here:

I think the answer for the 1.05. is, you can use anything
you want, subject to two restrictions. The FSB cannot be
adjusted too much, so if you buy a processor that needs
166MHz or 200MHz clock, you won't get good value from it.
The Bartons now have locked multipliers, so you cannot
bump the multiplier up, to get to their rated speed.
But you might possibly be able to use them. If you could
find an unlocked processor, to buy second hand, then
you could use a higher multiplier with that.

The processor you buy, also has to be recognized by the
BIOS, so maybe something like a Sempron might not work
(you don't want one of those anyway). I also don't
know if an AthlonXP-M mobile will work with this board
or not (i.e. the BIOS might not recognize it properly,
so you should check Google to see if anyone has used
one of them or not).

You should also consider how much memory bandwidth the
motherboard has to offer. You cannot expect every task to
speed up with the new processor, if the tasks make a
lot of accesses to memory. So, for the money you spend,
you may not end up with a machine that is that much
faster. It will be faster when it is compute-bound,
but not when it is memory-bound.

HTH,
Paul

XP1500+ thru 2100+ Palomino with BIOS 1007 or newer, per ASUS site.
 
äYes, I know about the Palomino. But that's been out of production for some
time...



I'm gonna try a TBred 2200+ (@12.5/13*133MHz, so slightly underclocked, but
the board gives no higher multipliers)(as the page, Dave Maynard suggested
to me in alt.comp.hardware.pc-homebuilt and Paul here, says)

(Cheapest of its ilk I found here in Helsinki/Finland, 64EUR)



As it's now, FSB 100 and RAM is clocked at 133MHz, so Paul's advice tells me
it's mostly CPU-intensive tasks that are going to see much speedup, but I do
rip my DVDs to HD.....

You would probably have trouble getting one shipped but there are 18 for
sale on Ebay right now. 37 sold for around $40US each in the last 15 days.
 
I don't have personal experience with an A7V133. My board is an
A7M266, but it's also limited to the PALOMINO 2100+. I was lucky
enough to make the upgrade during the last month or so when this CPU
could be had, and the switch was smooth. However, I read a lot of
posts about people who tried to use T-bred processors, and the A7M266
almost always fails to POST with them without hardware mods. If Asus
says that this board can be modified only up to a 2100+ Palomino, I'd
be reluctant to spend money on a T-bred 2200+ thinking that it would
POST, unless I'd heard from someone who'd actually done is
successfully.

äYes, I know about the Palomino. But that's been out of production for some

The 2200+ may work in jumper-free mode but when setting the jumpers
manually you need to take account of re-mapping.

I used a Tbred 'B' 2100+ with my A7V133 1.05 which would run at around
2000MHz (20*100) in jumper-free mode with default voltage. To use 133MHz
bus speed the jumpers need to be set to 9* multiplier (re-maps to
17*133.3) and vcore 1.8 to give a stable 2266MHz and a lot more heat.

These settings don't work for all boards but the chance of success
increases with revision number 1.04. and later.
 
Multiplyer remapping??
