why is my Xp 2700 cpu at 2100 ? 13X

[lotust]

Hey guys I thought the multiplyer is locked on these chips? I took out my xp1900 and droped this AMD Athlon XP Thoroughbred 2700+ in there. It seems my FSB will not go past 145 or so ?? what could be wrong guys ?

Was that novella really necessary? :roll:

Short answer - New motherboard.

Long answer - It looks like you're on a KT266 board. Which, if I recall correctly, can't support the needed 166MHz (333FSB) that processor uses. You're being pushed down to 13x133, which is the same speed rating as a 2100.

- M4H

I have a VIA VT8367 Apollo KT333

that should support 166 right ? I set it to 166 and it will not boot before i posted this.

I have Elixir 512MB PC2700 333Mhz DDR RAM Memory too


WTF :disgust: I also have the latest bios. AM i missing something

I think it was that Host CLK+33 need to be set to SPD in the Bios, What ever that does

If the mobo uses the KT333CE version of the chipset then it does have the 166mhz divider that is needed to run the devices at the proper 33mhz. If it doesn't have that version of the KT333 chipset then you will want to get a new mobo. I have a Abit KD7 that uses the KT400 chipset and will work just fine at 333mhz. $30 shipped for it. It also has complete overclocking features. PM me know if you want it.

BTW, you can take the heatsink off of the mobo and look to see if it has the CE version of the KT333 chipset.
