Processor bus speed and changing CPU speed.

[Cal20]

Hi,

Sorry if I am posting where there is already a thread created about this topic but I had a look and couldn't find any. I am having problems, well not problems because the CPU works but more issues with changing the speed. I have just installed AMD Athlon XP 3000+ processor i upgraded from a AMD Athlon XP 2000+ however the changes in GHz has barely changed. Have went from about 1.7GHz to 1.735. When I looked to up the speed in the BIOS to above 2.1 GHz (the highest setting) it said i had to have increased the Bus speed to 333Mhz or above and i could not located this.
Help would be great if you could tell me if it is actually a lot faster even though there hasn't been much of a ghz increase or if i should and can up the speed to 2.1 ghz.
thanks.

What is the make and model number of your mobo?

Motherboard Name: Asus A7V333
Chip Set: KT333

If you want more information I have quite a bit on the motherboard. Hope I can increase the speed because if not I have bought a CPU which technically is 10 models up from the previous but I am getting pretty much the same output!

Doesn't look like the AMD Athlon XP 3000+ is supported.

There are a few bios updates on the ASUS site with support for faster CPUs so it might support the 3000+. Looking at the manual it shows you have dip switches for changing the FSB. I'd guess the 3000+ is a 333fsb CPU so you'd beed to switch the switches to change the FSB to 166mhz.

In the bios, advanced tab, if you have the cpu speed set to manual, then you can adjust the speeds there. The option would be cpu/pci frequency. You'd up it to 166/whatever

Ah so in the Bios I don't need to change it to '333mhz' I change it to 166 and that corresponds to 333 like it sort of multiples? Or will there actually be an option of '333'.
And to Steve the motherboard does support it I had a look before I bought it and the 3000+ was the very last type. Seems to be working now as I am using the computer it is installed on.

thanks again all

also to add- in the manual in the last post I have found the jumperfree and sysclk dip switches and all the combinations they should be in for different speeds. Would I set it to 166 then it would be multiplied by the Frequency Multiple?
