CPU Upgrade

BIOS are routinely updated, and you'll need to flash the BIOS for the lastest version for your MB. Visit <A HREF="http://usa.asus.com/products/mb/ezflash.htm" target="_new">Asus Web Site </A> for Asus BIOS flashing info. You didn't post your version of your mb, but you can find the newest BIOS for that model at <A HREF="http://www.asus.com/support/download/item.aspx?ModelNam..." target="_new">Asus A7V266</A>. Sometimes, even though though the BIOS may not specify that it supports the next higher cpu, it often will work, but will boot with an 'unknown' cpu.

You can use only 266 MHz FSB Athlon XP. 2600+ was the fastest 266 MHz FSB Athlon XP. Now it's very hard to find a 266 MHz FSB 2600+. Current 2600+ and 2700+ have 333 MHz FSB, which are not suitable for your mobo.

Spitfire's right. Your board does NOT ACCEPT modern 2600+ CPU's, only the old 266 bus versions. Chances are the fastest 266 bus CPU you'll find is the 2400+

Thanks Guys, I was afraid that I might have overlooked something and apparently the front side bus was it. I did notice that the FSB was spec'd at 333 for the newer chips but I didn't realize the higher FSB would not work in my motherboard. Thanks for help everyone.

I have the A7V266-E and had a 1700+. I wanted to upgrade too, but had a hard time finding a 2600+, so I ended up going with the 2400+.

If you can get a XP-M(obile) Barton XP, then they run at 133Mhz/266DDR, plus have an unlocked multiplier. You could probably get one of those up to 3200+ speeds at least, although you may need a BIOS update.
