And I'm wondering if overclocking the GPU is possible and safe if I have the fans on turbo and the laptop cooling stand on full, and if so how?

Also yes I realise this would void the warranty and will not be doing it until my warranty expires as the reason I will be doing it is I will hopefully not be buying another computer for a long time and after 5 or 6 years say I will be planning to overclock to keep my computer able to atleast play new games on medium/low.

personally, I wouldnt ever overclock anything in a laptop, purely because the chassis isnt designed for this, therefore it may be not suitable to deal with the extra heat produced.

Not even with the cooling stand?

I'm interested in this aswel, is it ok to overclock with a cooling stand? or is it still too unsafe?

I would agree with Tom,overclocking on a laptop isn't a good idea due to insufficient cooling.
A cooling stand might help,but personally I wouldn't risk it.

You should look at the Notebookreview forums if you want to OC a lappy.

The people on these forums are not very enthusiastic about overclocking laptops.

Its not that we are not enthusiastic about overclocking in laptops, its that we wished to highlight the potential issues that may occur from overclocking a laptop cpu/gpu. The chassis are just not designed to deal with the extra heat. As the OP plans to keep his laptop for 5-6 years, the extra temperatures would certainly not aid the longevity of his system, even with a good cooling pad.

Thank you everyone for your advice, I'll take what you've said onboard and probably just upgrade it when it starts to go slow rather than overclocking then.

Very wise - the M part of the card name is the warning

No reason to bring a 2 months old thread back up - however its very interesting shortly after this thread was made a return was done for a faulty GPU on this laptop!

We state not to overclock the GPUs for a very good reason, its not that we are nasty, h8terz, or mean, we just know it can break them - especially on laptops where the cooling is made for that spec - increasing that spec is a road you dont really want to go down.
