The automatic overclocking features in the Bios say from a manufacturer such as ASUS?

If you have plenty of cooling then it should be ok right?

I have used it before and it's ok. I presume you are referring to the feature were you pick a % to overclock by, up to 10%. I don't think it alters the vcore at all, so it's pretty safe, but it's not perfect. Depends on the chip if it will take the overclock and still be stable. My old X2 3800+ wouldn't take a 10% overclock and be stable. This was because it needed the ram settings tweaking to be overclocked properly. Manually I could overclock it much more that 10%, but it was unstable on the auto overclock.

As for cooling, yes it's advisable to have decent cooling if you are going to do it. Again it depends on the chip, may of the recent Intel chips will overclock happily even with the stock cooler since there is so much headroom in them.

 

I only used the auto overclocking once and it worked well for me, but the overclocking was very basic. I don't see any issues with using that feature provided you have reasonable cooling of your pc. Personally I prefer to manually tweak the settings because I can have certain components take less stress then others, etc.

 

Thanks guys.

I have read quite alot on mobos recently as I am going to build a new system. Some of the new Assus boards have a feature where you just select the overclock option for the cpu you are using and it overclocks the cpu the ram Fsb etc.

I have read about QX6600 2.4GHz being over clocked to 3.0GHz by just using this feature.

 

I think a manual overclock gives you better control, especially important with your voltages. You can overclock a Core 2 quite a way with the FSB, not touching the vcore voltage and not generate that much extra heat. The heat comes from increasing the vcore, which you need to if you go for a fairly big overclock. I agree with Modey on the cooling, you really need something a bit better than a stock cooler.

 

When I build my new system it'll have a zalman cooler at the moment my system has a stock cooler.

 

Get yourself a copy of Everest Ultimate, lets you keep an eye on all the system temps, fan RPMs, voltages etc in a nice onscreen display. Knowledge is power!

 

wll do, thanks for that.
