Tip: Don't go overboard. Those things are terrible with dealing with stock heat output so keep an eye on your temps.

Pretty sure there has only ever been one line of Macs that you can overclock and I really don't think it was a MBP. Good luck, but I really wouldn't even touch that thing even if you were able to. MBPs are horrible with heat.

The only macs that have EVER been overclockable was the Mac Pro (Core 2 series). Otherwise, nothing else out there can be overclocked. rEFIt does not allow you to overclock your Mac, it is a bootloader modification to allow you boot other OSes OTHER THAN windows on your mac (such as linux, etc).
Also, MBPs should NEVER be overclocked. Even under the stock settings and under heavy load, the processor can easily hit 90C+. There is no room in the machine's cooling capacity to overclock the machine PERIOD. Leave it alone before you break something.
Sorry for being rude or being an ass. Trust me, I see things going down hill fast with this. Also, I work as a Mac Tech and I have done pretty much everything out there to try and overclock macs... it just doesn't happen.

Acctualy rEFIt allowes entery of EFI, the equivelent of BIOS, my AMD build is overclocked even though it has EFI. The only difference between the EFI on my asus mobo and a MBP is that on the asus EFI has a GUI that you can click. I know there must be a command.

Here is a thread related to the issue. rEFIt has absolutely nothing in it that allows you to really modify much and there is no way to actually overclock a Mac (other than the 2008 Mac Pros). Again, I have been there, tried to and fell on my face.
Also, I am aware that current motherboards use EFI, but also at the same time Macs have been using EFI for years. If you look at an OEM machine, the only way to overclock it is through software as there is nothing you can do in BIOS. The same is a mac, but Apple has pretty much locked out any possibility of overclocking via software. If you look everywhere, you find almost nothing on people overclocking macs.
The EFI on the MacBooks is completely locked down and also rEFIt doesn't actaully replace the EFI that is there, it mearly augments the boot loader section allowing it to see other OS installs. That is why you can easily remove it by deleting the EFI folder on the root of the drive. )also,l at the front of the drive is an EFI partition for the bootloader, rEFIt augments this, not the firmware on the machine, which apple has locked down). Additionally, anyhting related to the CPU, GPU, etc is controlled using a special chip called the SMC, which will prevent anything from drawing more power than allowed. So even if you could overclock it, the SMC will prevent you from really getting very far.Originally Posted by rabidz7

Xeb summed it up the best above. You are dealing with a heat issue mostly. That SMC chip is also the big complicating factor in the whole thing. Besides that, the chips are the stock Intel ones and not unlocked. I personally would not risk it.

Agreed. Think you should get REP for this.

My 1.25ghz model has been taken to 1.5ghz before with stock cooling

It involves soldering,but it's rather possible on G4 chips.

You clearly stated that the only macs that you could OC were the Core 2 Series. If you were excluding the PPC macs or eMacs you should have said soOriginally Posted by Lord Xeb

My gut tells me this is terrible in so many ways, but hey, this is overclock.net. If your up for a challenge OP, go for it!

I think I would just roll with Xeb's experience . . . he kinda has the rep to prove it.

Thanks. Trust me, I have tried and there really is no way to overclock modern Macs, and even the older ones, the only ones that could be overclocked were the Mac Pros from 2008.Originally Posted by KyleMart06

He is going to fail miserably and hit is face hard on the asphalt. I would prefer to save him the trouble and the trip to hospital if at all possible. Plus, he runs a VERY high risk of damaging his mac, and furthermore there is not enough cooling capacity to even handle the additional heat. Most macbook pros will run in excess of 80-90C under full load, even with their cooling fans kicked up to the max.Originally Posted by theknappkin

Hello
I just made an account specifically ask inquire here. I have a 2008 macbook pro 2duo how do i overclock it if Xeb has a way of doing it I would be interested in hearing what it is.
Thanks

He is saying that it is NOT a good idea to OC a MBP. He is talking about the tower Mac Pro being OC'd which would have the cooling support to backup the extra voltage. The laptops are just a bad deal to overclock all around. The heat just can't be dissipated fast enough.Originally Posted by silver-surfer

Also, even if you would succeed, the performance gain would be barely noticable. If you want some extra life out of that machine, install an SSD instead. Oh, and be ready to get the GPU reballed sometime soon.Originally Posted by KyleMart06
