Does VIA KT266A chipset support Athlon XP Barton CPUs ?

[Forrest Gump]

I've got a Gigayte GA-7VTXH motherboard.

Will AMD Athlon XP 2600 Mobile 47W Barton CPU OEM work with it ?

Thank you.

It might, but would post as "unknown cpu". But your max speed would be 12.5 x 133 fsb for about 1667. You really can't take advantage of the overclocking potential of this cpu. Computergeeks has an nforce 2 board by chaintech for about $50 plus shipping. Or check pricewatch for other nforce2 boards with the multiplier option. I ran my mobile 2400 at 11 x200 with an nforce2 board and pc3200 memory. Without good memory and a decent mobo, I would skip this cpu, and go for the xp2400 instead. Or save for an athlon 64 upgrade. My local Fry's has the athlon 64 2800 with ecs board for only $169 this weekend.

So you want to say that Athlon XP-M 2600+ will not even work on it's nominal speed ?
There's an AthlonXP 2600+(.13u) 266 processor in CPU Support List for my motherboard.
Is it a CPU of some other kind ?

I have a KT266A board here... the highest CPU speed it supports is 2100+ (266FSB)

however your results may vary.

Yes and no. The bus interface of Barton is no different to the others, so that's a Yes on the electrical side.

But: Desktop Bartons are 166 MHz bus frequency, which is something the KT266A is not capable of. Side effect: Don't expect the BIOS of a KT266A board to support a CPU the chipset can't run. On the other hand, there's a less-cache version of Barton, Thorton, that uses the same CPU core, and which you technically COULD use with this chipset. As seen on e.g. the PC-Chips M811U, a current and very popular low cost board that still uses KT266A and runs all CPUs up to 2600+ (133 MHz bus version) - including Thorton models, but not Barton.

The speed I posted (about 1667) would be correct. I've tried another board, and 12.5 is about the maximum setting many boards will run with when setting the multiplier for a barton. Some like the nf7 might go higher. If you must use the same board, you'd be safer with the regular xp. The barton at 266 offers no performance advantage. Go for the best price for either the barton or xp.
