Overclocking an old Pentium 4 HT 650

[ekuhlmann23]

Hello.

 

I recently found my dad's old computer with a Pentium 4 HT 650 clocked at 3.4GHZ, 1GB of RAM and an AsRock 775i65G. I need some help overclocking it. I went into the BIOS and apparently the multiplier is locked. The only overclocking option I can see is the base clock. I know that if I change it all the other components controlled by the north bridge will be overclocked so I wanted to know if it is a good idea or if there is another way to overclock. I really do not care if it will give me significantly better performance because I am only doing it for fun and also educational purposes. I will attach 2 photos with the system info and the CPU tab in the BIOS.

 

Thanks.

you have to use the base clock. that is the best way to overclock. newer intel chips just don't support it very well.

Thanks. I'll get to it then.

post back with the results. i am interested to see what it can do

I am using the Intel stock cooler with 1 system fan so results are not going to be impresive. After some testing I think 4GHZ is the highest I will get with the system still being stable and not overheating and throttling. I am currently running my 24H run of Prime 95 to ensure stability so I'll report back if anything happens. But I think that an extra 600MHZ with the Intel stock cooler is not that bad.

I will benchmark it to see if I am actually gaining performance when the Prime 95 test finishes but this system will not be used a lot so I do not really care if the performance is not so good.
