ATI Mobility Radeon HD 4500/5100 overlocking?

[Evrain]

Hi guys,

I'm a total noob when it comes to overclocking and have only recently heard about it and what it can do.

As shown in the title, that is the model of my graphics card which is in my laptop. I'm not sure if it's any different overclocking on laptops as opposed to desktop computers?

I've downloaded a few tools such as ATI tools and ATI tray tools, but I don't know which one to use! Or where to start. I've tried "scanning for artifacts" and it just scans for ages without anything happening?

I'm so confused at all the numbers and options!

Help would be greatly appreciated!

Thanks.

Not a good idea to OC laptops fella as the cooling on them cant cope. Its a completely different ball game to desktop GPU's.

I used to overclock a laptop I had. You just need to be more careful. It had an ATI mobility 9000 in it. Would overclock 150 MHz on the core and roughly 100MHz on the memory. Made a huge difference in UT2k4 and temps barely changed. That laptop did have all copper cooling and heatpipes though. You just really need to watch temps. Go slow and take your time.

Indeed, and what the enthusiasts should be telling you (assuming first of all that you're willing to take it apart) that the thermal pads used on laptop coolers are pretty crap, and merely replacing those with some good thermal goo should give you enough of an advantage to try an oc.

This is ofc assuming you're willing to open the thing up - but do bare in mind that it can be that much more daunting than opening up your pc.

You can lube the fans, you can adjust the voltage on them also.

Ok, so you oc it and gain some small %, once you run some benchies, you'll notice you're No.1 in the hwbot listings. (you can actually keep the case open and direct external fans onto it to do that)

At the end of the day, you have a decent 4500 mobile gpu and you could add some small % to it - in all honesty, you won't notice in general use. Except for your battery life.
