i720QM - Wont Turbo

[AmDaMan]

Hi chaps,

Just bought a 2nd hand laptop and it has a 1st gen i7 720qm 1.6x4. It's supposed to go to 2.6 or something under load but it just refuses to! The only way I can get it to exceed 1.6ghz is to use throttlestop and force the turbo..

The laptop is still fairly fast but it's just annoying! I've changed the powerplan, checked the temps, latest chipset drivers etc but nothing seems to work. It has the latest BIOS but it doesn't have any options in there.

Is there something I should be doing or is this just the way it is?

Cheers

That's a very good explanation, thanks!

I had a look at the 920XM and it looks like a beast, it's still fetching about 200 quid though. Is it worth me buying it or should buy a new laptop?

I doubt it will be that cool in a laptop though which could be an issue but 4 cores at 2.6ghz sounds like a hoot!

Matt - The 720 isn't bad. I'm looking to buy a couple of games in the future so that will probably test it more. General OS tasks are fine though. I just like having fast things I guess..

that looks serious!! That looks like a desktop version though with some serious cooling? A laptop might be harder to get me most out of? Can you select the turbo multipliers using throttlestop with the 920XM??

200quid seems like a bit of a bargain when i see that.. are there 2nd and 3rd gen i7's that have that capability? The only issue is this motherboard has the PM55 chipset so a bit old now, so things like sata3 and usb3 are missing etc. Not sure weather to buy a new laptop or just beast this one up.
