Hey does anyone have any recommendations on any AMD 64 laptops that overlclock well??? Alienware, sager...any?

I know some people say "oh no overclocking is bad"...I say don't be weak and by the time it messes your system up, if it ever does, it could be 5 years from now...

PLUS i have been overlclocking for 3 yrs now and its perfectly ran stable and fast... so please no msgs on that, just give me some good overlcockers

thanks guys

Laptop cooling can't handle it, that's the whole point. 65C is completely normal for _stock speeds_ under load, so forget extra volts... If you live in an igloo, then I suppose it could work. I managed to get 200MHz more for benchmarking (1,8GHz -> 2GHz) outside in cool air, but it was very, very unstable. Any one of the laptop cpus sold, especially Dothans, overclock well. It's only the cooling that limits it. Nobody likes to use stock cooling in desktop overclocking either, right? Well, laptop cooling is even worse.

Also, the bios most likely has no overclocking options, so you're limited to what programs like ClockGen can achieve. One person on this forum said he runs his AMD64 with a bit higher HTT than default. With luck, you could do the same. When I tried, I simply crashed.

Raising the multiplier isn't practical, because it'll screw up the automatic speed adjustments, unless you disable it, which will in turn result in a worse battery life. If you don't disable it, any overclock will be overwritten.

What's my point? Laptops aren't made for overclocking. Not because you'll break it, but because it's just not worth the effort for the minimal gain...

I agree with Sanna, OCing Notebooks is a big no-no

Sanna,
overclocking a CPU is a pain in the ass at laptops. You can push the memory timmings a little.
GPU/vram is easy to overclock. You can sometimes push the GPU up with 100mhz very stable. And the memory with about 50 (gateway m505X) 100 real mhz, cause it is DDR memory.
The best performance improvement you get from OC the video card.

the most overcloking you can get is from the gpu. they are usually underclocked in order to get more battery life and keep it nice and cool (*cough* i mean warm).

Agree with all of the posters so far.

Laptops are not meant to be overclocked. They were not designed with pure performance in mind. Their cooling systems simply cannot handle it.

If you want overclockable, powerful, yet portable systems, I think your best bet is a SFF PC.

From a cooling stand point some cpu's are likely to be overclockable even in a notebook. Such as a 1.6 Dothan, all you have to do is look at the same cpu scaling up to 2.1 GHz in the same notebook. Not that you could get over 2 GHz with every 1.6 but a lot of them probably do have some headroom. Still, software oc'ing is the pits, especially non motherboard specific programs.

hmm i gotcha... do many people buy better cooling such as heatsink to keep it cooler then?

i might jsut oc my gpu then...

They don't sell alternative cooling solutions for laptops like they do for desktops. The only thing you can get is a cooling pad, of which there are several alternatives.

OC the video card, and just save yourself the trouble of OCing your CPU. My GPU went a lot higher than stock, and it's in a laptop where the GPU gets no active cooling at all too.

In general, I agree with most of the people who said that OCing a laptop is an incredibly smart thing to do mainly because of the limited cooling abilities of the slim laptop cases.
However, if OCing is what your heart is set on, I would have to say that eMachines M68** series has very little competition out there.

Why, do you actually run yours overclocked?

Oh yeah

O'cing GPU is real fun
Just got trouble with the drivers , none 100% perfect so far

Yes, in general OCing a notebook is not a good idea if you idea of overclocking is bumping the processor up more than 10% of its stock speed. But if you want to try anyways, I recommend using clockgen as it is CPU and motherboard specific. Personally I've only upclocked my CPU 100mhz (1900 from 1800) on an AMD64. I don't know what the limits but I've heard people running at 2.0ghz from 1.8 on AMD64. I don't know how much the Pentium M's can upclock however. The real money is in OCing the GPU. They upclock fairly well depending on the laptop. Mine went from 459/209 to 485/249 w/out artifacts.
