My motherboard is SIEMENS AG D1107 and this is my processor:

My BIOS is very old (Phoenix 07/05/99) so no way I can change the FSB settings from it.

I'm going to buy a new processor but until I haven`t got my hands on a new one, I want to overclock current.

I would be pleased if someone responds.

considering the sheer age of the system, any performance benefits are going to be negligible. Its a little like strapping fireworks to an old donkey to make it go faster. You're likely to get better results using the system with an OS that will run well with something that slow. – Journeyman Geek Jun 13 '11 at 6:58

The Pentium III processors were multiplier locked & the only way to overclock them was to increase the FSB. If you can't increase the FSB, then you can't overclock them.

You'll need to find an updated BIOS. Can't find it anywhere, unfortunately – Sathya Jun 13 '11 at 12:20
