Can I put a 2.5GHz Logic board in a 2.4GHz case?

I'm pulling a logic board from a MacBookPro4,1 and I want to put it in my MacBookPro3,1 and need some advise. First, will it work? If yes, should I pull anything else? What I mean is, are there any other parts that are better in the 2.5, like a faster Airport card?

Thx bunches.
 
Hmm... You'd need to swap the keyboard and trackpad as well if you want to retain the 4,1's full functionality, I think.

The 3,1 doesn't support multi-touch in its trackpad and it also has the older keyboard (without play controls etc.). I've got a 3,1.

I think I'm right in saying it's the 4,1 that introduced those changes? Not 100% sure, though.
 
For anyone else asking wondering "can I put a 820-2249-A logic board in place of an 820-2120-A logic board?", the answer is 'yes' but 1 single torx screw doesn't line up and it is this one:

other than that, it works fine. ;)
 
The screen probably won't work. The 2.33GHz one had a CCFL backlit display, while the 2.5GHz had a LED backlit display. I can't see that playing out.

No, it was a 2.4Ghz and all it working great. I'm a little scared about that screw alignment, as the CPU is right below that and I worry about it not connecting to the heatsink, so I screwed everything else in super tight.

Why not swap the heatsinks from the machines? they're physically the same shape, no?

Well the 2.4GHz had LED backlighting.
You said 2.33GHz in your title......

Doh!!! :rolleyes:

Don't over tighten the heat-pipe, making it tighter doesn't increase the pressure to the heatsink, if anything you'll squash the logicboard and at worst, the screw will break!! They're fairly fragile!!

BTW, while youre in the machine.. might be an idea to de-dust those coolers ;)
