Matching CPU speed to motherboard

  AJ59 19:41 12 Jan 07

I have just purchased an Athlon XP 2800 which has a real speed of 2083 Mhz. My motherboard is an Epox 8KHA+ DDR.(current CPU Athlon XP 1600, speed 1.4 GHZ)

The Epox website states that the 8KHA:
"Supports Socket A compatible AMD AthlonTM XP processors 1500+ to 1800+, and 600MHz to 1.4GHz AMD AthlonTM and AMD DuronTM"

What would happen if I install the 2800?

Would I damage the mobo or would my system run at the higher speed?

Any help or shared experiences would help!!

I would doubt anything would happen as the new CPU is so far outside the range of processors supported by the MOBO it's unlikely to recognise it. So while I don't think you'd damage the board, I also don't think the new combo would do anything at all.
Get a new MOBO.

I agree with Belatucadrus on this one.

Nothing will happen. The computer will not start

According to the epox site (click here) the 8khi3425.bin (25 Apr 2003) bios update added Improved Atholn XP2600+ stability, there is another update just above, 8khi3916.bin (16 Sep 2003), though no details on what the update was for.

So while it seems, with the updated bios, the 2600+ chip is supported, there is no mention of the 2800+, you could try it with the september update, it may work (but at the rate of a 2600+) or it may not. Suckit and see;-)

Thanks for your thoughts Belatucadrus, madboy33©® and vinnyT on the above - I will try updating the bios b4 changing the CPU - If this does not work is it easy/viable to change the mobo..?

There are 2 versions of the 2600 (266 and 333 mhz FSB) and I suspect the 266 Mhz FSB version is the max your board will support. The 2800 has a 333mhz FSB speed - BIOS updates won't overcome that.
