Hello,
I just got my Macbook pro 15 inch 2.4Ghz with 330M GT for some weeks now.
And I wanted to play some games in Bootcamp so I thought of overclocking my card as well.
First of all I wanted to ask if someone else also had downclocking problems? It seems to be related to this new called 'powermizer' feature. It seems mine just underclocks without reason, not temperature related. When I'm idle it drops back to 450Mhz (core) and the rest goes down as well. And When im trying to start a game again, it just sticks there until i reboot. I cannot change it no matter what clock-setting program I use.
I have now redeemed this problem by using a program called NVPMManager.
Anyways I wanted to post my clockresults as far as I tested for now (Stable)
670MHz Core
1060MHz Memory (Seems to be quite good DDR3/5 memory?)
1500Mhz Shaders (It seems i can go up to 1520MHz but I get some glitches then after a while).
GPU Temperature: Mostly stays at 69C while playing GTA4 but can go to 73C MAX after a long while. (Ambient chamber temperature of 22 degrees)
I will post some 3Dmark05 and 06 scores as soon as i finished downloading em
Edit: Ok here they come, it seems im even outranking the i7 Macbook Pro users

3DMark05: 15559
3DMark06: 8280
They can be found in the Futuremark ORB Database.
Im very pround of my little Mac.
(For the GTA4 / EFLC users, I can play quite smooth on the following settings

Resolution Native 1440x900
Texture Mode: Medium
Shadows: Medium
Reflections: Low
Detail Quality: 50
Detail Distance: 15 (Because of the lack of more video memory, I can make this higher but it wont have any effect except for more buildings and textures trying to popup out of nowhere, 512MB users should have more luck)
