Laptop overclock help

post #1 of 11
Thread Starter 
I have a Toshiba satellite with a Mobile 1.83 Ghz Core 2 duo processor. I'm having issues with my computer slowing down and this is the last piece of the puzzle that hasn't checked out ok. I was wondering if there is anyway to overclock it to 2 Ghz or so.

This link has all the specs for my laptop:

Thanks for any help.

Overclocking your GPU, sure. For the CPU, I really won't advice that for a laptop ....

I wouldn't overclock your laptop if I were you! If you lay the laptop in your lap as of right now do you notice how hot it gets just at stock settings? Imagine overclocking that and not being able to cool your cpu as it will be needed.

Wrong. I hate all the fear mongering that gets thrown around when it comes to over-clocking laptops. The truth is, if the laptop is not having problems now when it comes to efficiently cooling the CPU and GPU or IGP, it won't have problems if you over-clock with no voltage increase. It's only components that are running hot which shouldn't be over-clocked.

I over-clocked the C2D P7450 on my laptop from the stock 2.13GHz to 2.6GHz and the only change has been that the temp. has gone from 65C under full load to 67C, which is still well under the max. temp. of 90C.

As for the GPU, I'm being more careful with that because it is quite hot and powerful for a laptop GPU. It already gets stock to 95C on Furmark and pushing it to an overall 15% over-clock makes that 98C. Still, it's under the max. specified 120C, so I'm not too worried.

If anything, over-clocking the GPU is more dangerous than over-clocking the CPU because it rises temps. more. Only thing you really need to worry about is if the laptop's chassis can take it.

Post your current full-load temps. for the CPU. Since from what I can see your laptop has an IGP, don't bother: it's too slow to make a difference.

Don't listen to the fear mongers.

If Axel's done it, then you should listen. (Though I personally chose to undervolt my cpu and OC my gpu for now. Might OC the cpu later)
I agree, post your average/load temps here just so you don't make your baby go boom boom when/if you oc.

Also, Axel. Mind sharing your tools/method of OC-ing your processor here? Most manufacturers don't have BIOS options to allow OC-ing laptops (pretty sure his falls into that category but i stand to be corrected)

Op: download Coretemp and let us know what your idle and load temps are. Use Prime95 to load the cpu to generate max temps. Choose "inplace Large FFT's" under options>torture test

Keep these programs too, they will be needed later on to test for a stable overclock if you so choose to overclock.

I just use SetFSB. It's widely used for this purpose. For the GPU, if it's dedicated, I use MSI Afterburner.

Yeah, I'd go for setFSB as well. Though that's only feasible if you know your pll (or are pretty darned lucky). Couldn't find his specific laptop's pll and I can't say how the similar Toshiba's will work for him though.

What do u think?

(I prefer GPU overclocks with rivatuner. Just modify the config file to support the mobile card in question)
