overclocking noob

[dailo]

Hi,

I'm thinking about purchasing a Intel P4 2.8 ghz and overclocking it to a 3.0 or 3.2 ghz and I'm not exactly sure how to do it. Does anyone have any good sites that could provide me with some helpful infromation.

I will probably using an Abit BH7 board. Also does overclocking require a better heatsink, or is the stock powerful enough?

I also have a Intel P4 2.0 ghz system on a Asus P4B533 that i'd like to overlock, but not quite sure how to do so. Any help would be appreciated, thanks!

since your OC is so conservative, it is very likely that the stock HSF will be sufficent

a 2.8C is 200*14. if u change your FSB to 215, you will be at 3 ghz (215*14 = 3010)

Check out "adrian's rojak pot" for bios tips. It might also help you with overclocking.

How do I know what multipler to set it to, and what I should change the vcore settings to? Also does overclocking the CPU require overclocking the RAM as well? Thanks again.

The multiplier on a 2.8 is 14. (2800/200)
The stock Vcore settings should be fine for 3.2. If you run prime 95 for a while and its stable don't change it. If not bump it up one increment at a time until yopur system is stable.
Depends on memory. Yes and no. If you run a 1:1 ratio (cpu:ram) and you ran a 214FSB (3.0) Ghz Your ram would be overclocked if you are running DDR400(3200) but not if you were running DDR433(3500).
At 3.2 it would be necassary (probably) to change the divider to 5:4 Where the cpu was running at 3.2 and your ram would run at 182Mhz which is below the rated speed for 3200.
You may however get 3500 to overclock to 457Mhz without taking the memory speed hit you would by changing to 5:4. You could also move to DDR466(3700) or higher which would allow you to easily run a 3.2 OC on the 1:1 divider.

thanks for the help, I think I understand what to do now. One last question, I was just wondering what are the downsides, if any of overclocking? Is it true that if you overclock, the CPU "dies" faster or clockspeed lowers later on? Thanks.

Two things will kill the cpu. Heat and voltage. Try to keep both down and your cpu will be obsolete long before it dies.

Listen to the guy above me. I'd rather get the most of the CPU while its worth something.
