Undervolt 2630QM?

Hey guys,

I'm just curious if it's possible? The Intel XTU v 2.1 that I have only allows me to change Turbo Boost settings, which I guess is it's 'auto' overclock. And even then, all it lets me change is the power consumption in Ampere per core (97? really? Am I missing something, or is that a LOT?), Watts, and Voltage.

I'm trying to get it to run cooler in idle, for the sake of my ears- the fan's always changing from reasonable to kind of annoying, back and forth...

 

ThrottleStop might be able to do this but I'm not 100% on that. My last laptop had fan problems and basically I had two options - wear headphones or throttle the CPU through power options.

 

Without a modded Bios, I don't think it's possible to do so on the stock model. You can undervolt the GPU, but the CPU is locked.

 

The 97 amp number refers to the maximum turbo boost amperage for the entire CPU. It is impossible for your 2630QM to draw 97 amps and adjusting this won't do anything for your idle temps.

Many manufacturers are using fan profiles that are retarded. Instead of using a fan speed that is sufficient to keep the CPU and GPU cool when lightly loaded surfing the net, they turn the fan way down or off. This lets everything get too hot then they are forced to kick the fan on at too high of a speed to cool things down and this cycle repeats infinitely. As you know, that's very annoying but there isn't a hell of a lot you can do about it. You can try re-doing your thermal paste but other than that, you are going to be stuck with this irritating problem.

 

This is spot on.

The problem is that some laptops can't afford to run at the low/no fan speed when it is lightly loaded. Think about it, it may be quiet but it could be getting to 70C or whatever not doing much at all. So, when it needs the fan to be on blast, it is trying to cool down a processor that is already at what should be load temps. To put it simply, it's easier to keep the processor at light load and when it gets loaded up it might not pass 70C because the fan was on at a lower temperature, it's harder to keep a processor at a certain temperature if it is already too high.

I hope that makes sense.

 

impossible to undervolt...

You can however try to limit the maximum turboboost frequency.

I noticed the voltage for 2ghz is a lot lower than 2.8 ghz

For playing ArmA 2 I disable hyperthreading by parking 4 cores. So I actually have 4 running and 4 parked.

Then I limit the heat by setting max freq to 2ghz or 99% max processor state.
