Overclocking laptops? Whats the deal?

[JImmyK]

Hi guys Im running a 3 yr old Master K7D with 2 overclocked XP1700 chips running at MP-2800 speeds.

I was thinking about getting a desktop replacement laptop so it wont be moving around much and I will have a pretty high end graphics card in it, but I was wondering if I can overclock their Core Duo processors? I have been out of the game for sometime now some examples are the e1705 from dell or the HP Pavillions which have a great design.

cheers

I have no experience in overclocking laptops. but HP Pavilions are a good choice.

I've pin modded (for voltage and fsb) Pentium-Ms before, but have not had a Core cpu to try yet. Search around these two places as there's a lot of good info in those forums and some of the sigs as well:

there's a guy on this forum who's claimed to OC a Pen_M to over 2 GHz and sez it matches an Athlon FX-55.

sagernotebooks offer desktop replacment notebooks that are fast enough where you do not need to overclock anything. in fact, you'd be more than happy to underclock your parts to save battery life if any of that mattered, should you be on the go and don't have access to additional power sources.
-dual core
-SLI/crossfire setups
-SATA/RAID configurations

some kids severly OC their integrated Radeon 9700's to play FEAR. Ridiculous, but the settings are acceptale to them.

Currently running P-M 1.6 @ 2.13 in my Asus Z70va via pin mod. Most P-M laptop with FSB 400/533 support can do it. The difference is some laptop has easier access to CPU than others.

Not sure if there is anything on Core Duo/C2D yet.

Currently running a PentiumM 1.8 at 2.4 in my Dell 9300 -

Very fast

Not sure I would want to do that. Laptops have very poor cooling systems, and are not designed with a lot of slack in that area. Since frequent mobility does no appear to be your objective, maybe a tablet or an SLI box would be a better choice?

I agree, laptops are small because they have a small heatsink and fan. I've got a p-m @ 1.6 and it gets hot. I wouldn't reccomend doing that unless you dont mind purchasing a new $250 pentium m once evry 2 months. If you want to, the pin mod is the way to. But i wouldn't do it.

Pin mod is pretty much the only way to overclock laptops. All a pin mod does is raise the fsb. Pentium Ms can be pin modded, but I haven't heard of anyone pin modding a core duo, even though there is a way to do it.

First off great info thanks for that guys secondly I was asking for overclocking for a 2 fold purpose.

I was hoping it could be done via software because if/when I do travel I wanted to underclock it and reduce voltage for longer battery life, and when sitting at my desk I could up it.

I know laptops dont seem to be the best cooling wise, BUT on most of my laptops the fan turns on maybe once every ten minutes. Im assuming because it reaches a certain temperature and vents the hot air, laptops seem like the perfect venting design which has proven to be EXTREMELY effective cooling, so instead of the quite little fan turning on every ten minutes if it just stays on I think it will sufficiently cool.

I will follow those links above and keep you all posted if I find an easy way out, cheers!

Isn't that just about what Speedstep does?

You can force lower voltages with NHC.
