Anyone have any experience overclocking the CPU?

I've got the GPU to overclock just fine, and with hardly any heat added to it. Dont always use it, I only use the OC'd GPU when I'm playing a game that needs it. I want to play around with the CPU and OCing it but haven't been able to find much info on it, like how much heat it generates or if people have found a sweet spot for it, like I've seen some people talk about the GPU, where it doesn't give that much more heat at all and still give an impressive performance boost.

 

You can't overclock the cpu to my knowledge. It's not an "unlocked" cpu. Only processors that end in "k" are unlocked and ready for overclocking, like a core i7 2700 vs a core i7 2700k, only the k is overclockable. And even if it could, i wouldn't mess with it, at moderate usage it's already very hot in the m14x, any hotter and damage can happen.

 

I know the CPU in the m14x can be taken to 2.9GHZ. I just wandered if anyone has any experience with it. I've got a cooling pad, and plan to put on my own thermal paste once I learn how to do it.

 

Oh, you're talking about the dynamic boost, yeah it automatically clocks it self to 2.9 under heavy usage, so you don't have to do anything, it does it by itself. If you want to see where the current cpu ghz is at, at any given time, download the intel turbo boost monitor. But as far as actual manual overclocking of the cpu goes, it cant be done. But the turbo boost is good enough.

 

2.9Ghz for 2630QM
3.3Ghz for 2720QM
3.4Ghz for 2820QM

This is why I upgrade the CPU from the stock to 2720QM, for the a little bit higher clock speed.

 

the 2630QM maxes at 2.6ghz if all 4 cores are boosted. Usually mine will sit at 2.6ghz if I am doing anything mildly intensive. 2.9ghz is for one core only.

 

Yeah, I forgot to mention that, The more core active the less amount it can boost, like mine, when I playing BFBC2, it usually shown that the Core #3 to boost to 3.29Ghz ~ 3.3Ghz while the other 3 cores are between 0.79Ghz ~ 1.79Ghz.

 

i only overclock the gpu.
dont even know how to overclock cpu. i just open up that intel turbo boost hopefully that does something lol

 

For the CPU, I know you can raise the FSB in the BIOS which provides marginal improvements to clock speed. My 2630QM's base is 2 GHz however I'd managed to get higher than that on 8 threads, and closer to 3.1 GHz on a single thread.

A good idea is to leave everything else other than the FSB setting alone since otherwise your temps will go straight up (no joke).

 

So I just go into the BIOS and change the FSB and it increases my CPU speed? does it like get my CPU to use the turbo boost all the time or like how does it work?

 

No, turbo boost happens only when not all cores are used and your CPU is below its TDP. Change the FSB from like 99 MHz or something to 103 or w.e the highest for you is. Then run CPU-Z and run a benchmark, like FritzChessMark, and look at the speeds shown on CPU-Z.

Changing the other settings sets how long the max TDP of the CPU is allowed to be reached for, which shouldn't do damage technically but it will raise the internal temperatures a lot under load.

 

Well I certainly dont want more heat in this thing so no changing the TDP for me. But the FSB sounds interesting. So just changing it a bit gets more out of the CPU and doesn't increase heat(much)?
