Overclocking the i5

[DerekRod]

I have a MBP early 2011 with 4GB ram and an i5.Overclocking the processor is it a bad idea?

 

[tninety]

Is it even possible?

 

[DerekRod]

Thats a good question,This is my first Intel mac so im not sure.Only ever owned PPC Macs before this

Possible in boot camp of course, not sure about OSX. Why would you want to OC a mobile CPU though?

 

[DerekRod]

Not that i want too its more of a rhetorical question out of interest.I just worded my op wrong

No, it's not. The CPU has a locked CPU multiplier and the BCLK cannot be changed by more than a few percents or the system will become unstable (and you would need BIOS/EFI access for that anyway, which is not possible).

Ah, I didn't even think of that. I was thinking back when I used RivaTuner to OC the GPU in my iMac, forgetting that the MBP's have locked CPU's.

If it can be made; it can be unmade, however the likelihood of unlocking the correct setting has a slim possibility.
