Overclocking Athlon XP 2200+

post #1 of 4
Thread Starter 
How far can i clock my Athlon XP 2200+
It's now running at 13,5*133!
I can make it 13,5*165
But can i make it higher?
It's good cooled with 4 fans!

thanks

I've never heard of your motherboard. The only way to overclock that processor would be to raise the FSB like you said. What limits your FSB being raised is something called a "PCI/AGP Lock". This "lock" keeps your PCI and AGP frequencies from changing with respect to the FSB. A board that has a lock, can go from FSB 100 all the way up to 200, with the PCI/AGP frequencies staying at 33/66.

If your board doesnt have a lock, your PCI frequency would raise as you raise the FSB.

Example:

- If your FSB equals 133, and your PCI frequency is 33...you can, for the sake of math, say there's a 4:1 ratio for FSB to PCI.
- If you use the 4:1 ratio (which is not the ratio to always use...use only for starting at 133) and increase the FSB up to 165, your PCI frequency will now be ~40Mhz.

Anyone will tell you, 40MHz is bad! It will fry a harddrive, will make a CD drive do spooky things, and in general is just not good for your system.


Oh yeah, and Welcome to the Forums!

Not to bad actually. 2200+ actuall Mhz out of an XP2200 is not bad, must be a B core. You need ram that can excede your FSB so you can up the FSB and reduce the multiplyer. The faster the FSB the more effecient the OCing.
That is if as earlier stated and you have a PCI lock and the CPU is not locked.
Keep your load temps below about mid 50c too.
What is your voltage at and the CPU temps idle and under load?

That is a Via chipset board. The acp/pci bus does not lock. If you can set the divider to 5(that's a 5:1 ratio), you can go to 166 mhz to 180 mhz without corrupting the hard drive. I don't know if a PC Chips board gives you that option. I don't go over 72/36 on my Soyo board.

Looking at your specs, you are not going to get that far on PC 2100 ram.
