What is the exact model number of the cpu? Is it supposed to run at 1.8Ghz or is it a XP1800+

To run a AMD 133Mhz cpu, you must alter the jumpers on the motherboard. Both must be on the 2 and 3 pins.

If your processor is in fact an Athlon XP 1800+ then the actual speed of this processor is 1.53GHz click here and click here.

its a 1800+, when you say 2 nad 3 pins im not sure what you mean as the motherboard has two rows of fsb pins 3 in each row and thy are settings of 200mhz 266mhz and 333mhz

Both of FSB_SEL0 and FSB_SEL1 need to have their no. 2 and no. 3 pins jumpered.
If you don't have a manual click here.
Since you have confirmed that it is an 1800+ then 1533MHz is the correct speed for it and the FSB should be set at 266MHz.

The jumpers on your motherboard are here. click here two sets of three pins

You need to cover the pins 2 and 3 on both. Like this click here

This will set the fsb of the motherboard to 266Mhz. The correct speed for your cpu.

Then as Eric10 has said. Your cpu should show as a 1800+ and run with a clock speed of 1533Mhz.

i set the fsb jumpers to 266 as shown and it would not load just went to welcome screen and rebooted over again and again :-(

AMD XP 1800+
Internal clock 1532.9MHz
System clock 133.30MHz
System bus 266.59MHz DDR
The statement you get is correct your CPU is only 1.5gigs if your system is rebooting i would suggest it is nothing to do with your processor...

PS did your PC work properly before you altered anything

yes it was working fine
if i put in the fsb manualy it works ok for about 30 mins then reboots or if i try to install of a cd ive now just found out :-(
