Athlon XP CPU

  cnl 10:53 10 Sep 2003

Hi everyone.

Can anyone tell me if the Athlon Xp CPUs will work with on older motherboards?
I have an Asus A7A266, which was released when the Athlon 1.2Ghz was the latest chip. As such, the quoted max CPU speed is 1.2GHz+. The multiplier also quotes 12.5x or higher. I'm running 512MB DDR RAM at 266MHz (2x133MHz). Does this mean I could run an Athlon XP with a 266Mhz FSB up to roughly 1.67 GHz or more without a problem? (such as the Athlon XP 2000+?)
Also will CPUs with higher FSBs run at lower settings, ie is the quoted FSB the maximum or does it require RAM of the same speed?
PS (but not so important, I'm sure I can find these out if I look) What's the Athlon MP and the barton core?

This is a big help to me,
Many thanks to everyone,

click here The board apparently supports up to a 1.2GHZ. BIOS upgrade may help.

Thanks mark500.
I checked those links out but I cn't find any info on whther the MB is Athlon XP compatible, or if the Athlon XP CPUs are compatible with any Thunderbird MB. I also came up blank on the FSBs.
Any other help or suggestions would be very appreciated.

The ASUS A7A266 is a Socket A DDR motherboard based on the ALi® M1647 chipset. In addition to significantly enhancing system performance with support of the latest DDR SDRAM, the ASUS A7A266 offers flexibility by also supporting PC133 SDRAM. AMD Athlon/Duron processors of 500MHz up to 1.2GHz+ will benefit from the optimal performance delivered by this ATX motherboard, and you'll effortlessly power through today's most demanding applications like never before.

You're right the BIOS update does allow the MB to support up to the 2600+ XP, and I assume the FSB is scalable.

Muchas gracias for the info,
