notebook processor overclocking

Ive never done overclocking before and so i'm completely new to this. Ive heard it done on a desktop but never on a laptop before. Is it safe? What are the power and heating issues? I know on a desktop you have to up the power and cooling but can this be done for a laptop?

Also, is there a program that can do it for you or do all the modifications have to be done through the BIOS?

Thanks.

 

Hi,

I have it in my BIOS - 5% overclock. It brings very good performance increase and heat can be easily controlled with undervolting.

The only other way I know is with ClockGen. I think it works with older 8xx Intel chipsets.

Cheers,

 

You won't be able to do it like you would on a desktop (p4 can go to 5ghz with water cooling) but you can see increases. I have my 1.6ghz p4 running at 1.7ghz and it does fine and actually I have mine running cooler than when it shipped from dell.

As for pentium M's you can also do something called pinmodding which can add 600mhz of power.

 

There is also something different from Clockgen: setFSB

I was not successful with my lappy, but some people reported success with theirs.

 

Thanks ivar - I did overclock my old Asus with 8xx series chipset with ClockGen - it worked fine (and fast). I will try this tool and see if it works.

Cheers,

Thanks for the great info guys!

I have a Celeron 2.8 Ghz - embarrasing i know but it will be replaced in a couple of months by a Core Duo!

Can this be overclocked? Also, what is pinmodding and how can it be done?

 

Beware, last time, when I downloaded from this site some setfsb tool, it was
infected with some "Kill.Win.. .C" troyan (detected by BitDefender).

So far I was not successful with overclocking my notebooks.

 

Hey Ivar - no trojan, but no luck either. I tried all 915 chipset tools and some of them could be started, but couldn't access SMBus or something. Not good. I think my BIOS has the contol over it because I can overclock my notebook there, but only 5% FSB. It is a very good gain though!

Thanks again,

Ivan

 

I also have uniwill notebook (223ii0) and the "maximal performance"
BIOS setup which allows to work with 10% higher FSB (as well as with the 20% lower
using the "P" button ).

Clockgen didn't see anything, I still have to try all setFSBs. However, I don't feel I really need it on this laptop. Its performance range is good enough anyway. These smart setups is what causes my respect of Uniwill, but their cheap plastic design is somewhat disappointing.

 

You're right. 10% you say? Great! I can do only 5%. Tests say that PM 1,86 at 1,96 GHz is a bit faster than PM@2,0 GHz. That is enough for me too. My brother has Prestigio Visconte 13" with the "S" button that brings Pentium M 1,73 GHz multiplier down to 4x! That is really something. I thought that all PMs have 6x as the lowest multiplier. It must be something on the hardware level. It gives him almost 2 hours more on battery. Fan never goes on.

I am also quite satisfied with Uniwill so far. Robust, fast and I can access and read temperatures for the MXM Ati X700 GPU (GPU + ambient temp). Overclocking, underclocking, undervolting and other NHC + ATT magic works great. Very good platform indeed. I just wonder when will the Clockgen or setFSB support my clock generator. Somehow I expect it to run even better.

Cheers,

Ivan
