Can this ASUS A7A266 motherboard rev 1.10 also run Athlon XP Barton processors with an FSB of 266, or are the Thorton and Thoroughbred the last processor series that can run on this motherboard? I'd like to put a Barton on it because of the 512kb L2 cache.
If I'm not mistaken, Barton core had an FSB 166 (333) MHz bus clock, the board can only officially do 133 (266), so if it works, it will run at a lower speed.

There definitely are 133Mhz/266MT/s barton CPUs, for example AXDA2800DKV4C, though i am not sure if those would work on this board...

There are also Barton MP/XP-M CPUs that are 266FSB that should work just fine on this board.
Mobile variants may also be far easier to obtain too and cheaper than the full XP 3200+ models.
Oh, well boys, then that makes my memory weaker - thanks for the clarification.

Barton had a few different versions, the 266, 333 and 400 FSB models. The 3200+ 333 FSB one IRC was OEM only and is rather rare to even see but the other models were plentiful.
There were 200 FSB models as well but they were all Athlon MP socket 563 versions.
https://en.wikipedia.org/wiki/List_of_AMD_Ath … n_XP_processors is a great resource for checking which versions are out there.
