How to over clock a old Athlon 64 x2 4200+

See if this Link is of any help to you.

Hello

Thanks it helps some but doenst tell me how to over clock the cpu. I do not know which values on which things to change

The mb has listings such as SB voltage, NB voltage, DDR voltage, etc.

I need to know which things to change and how to change them.

I used to have that exact same M/BD at one time but do not remember the settings any more. So that is the reason I'm giving you links. That being said;

Here is an review from Toms and a OC'n guide I found Here at Overclockers .com.

I truely hope this helps.  

Thanks

Hello

I follwed the guide and it worked well but when I went in and adjust the ram speed(within safe margins) the computer will not start up. The power button comes on and the fans start but the computer will not start up.

Do you know how I can get it to star up again?

You should see a jumper near the CMOS battery, (labeled CLR?). There are 3 pins with a jumper in 2 of them. Like 1 and 2 or 2 and 3. Move that jumper to the other 2 pins and remove the CMOS battery and unplug your power supply all for about 1 minute. Then put the jumper back where it was and the battery back in and then plug your power supply back in.

This will reset your BIOS to default settings allowing you to go back in and try to OC again.

Hello

Tried it but didnt work. Do know of anything else that might work? MB dead?

Try it doing it in this order; unplug power, move jumper(make sure it is the right jumper) and then remove battery. Sorry I was not more specific on this.

Of course you may have done it that order so if it does not work let me know.
