AMD XP 1800

  howard64 16:58 04 Aug 2007

I have just replaced an XP1000 with an XP1800 on an Epox EP-8KTA3L+ motherboard with 1GB of Ram. This mobo is set to default which should correctly detect the cpu and set it up. This is showing as a 1.15GHz cpu, is this correct? If not does anyone know how to do it? I have visited the Epox site but this 'socket A' motherboard is not listed by them. The pc appears to be working correctly if a bit slow. I have the manual but it does not make it clear how to set the cpu if it does not detect it automatically. Any suggestions would be appreciated.

It should run at 1.53 GHz

thanks Fingees now all I need to do is find out how to change it.

Check if there are some little switches on the motherboard, possibly surrounded by a very mini blue box,

yes there are but they are all set to off at the moment

Read the manual before doing any changes, it explain it all, which switch should be on and which ones should be off, for the CPU

There should also be a jumper on the board that will increase the FSB from 100 to 133, allowing your CPU to run at the correct speed

If no jumper check the bios FSB setting

sw1 cpu vcore voltage selection
sw2 cpu ratio selection. Does anyone know which settings these should be for an xp 1800?

thanks all now sorted - found a jumper on the mobo which set cpu clock. It was on 100MHz and by changing it to 133MHz it then showed that it had an xp1800+. Thanks again
