modified INF not nessesary?
Let me start by saying that this is a great thread with a lot of good info, but let me post on my experience with all this: first, im running Win7 with a 9600GT on a 15" MBP. Yes, I know it different than the 330M we are talking about, but same driver, same platform, same method to OC. That said, I installed all the Bootcamp drivers, went to add/remove programs and removed all the NVidia drivers and downloaded the new drivers from their website, where, at the bottom, it said that the drivers allow for overclocking. I benchmarked my machine 3 times and consistently scored between 6030-6080. Then I OCed it using MSI Afterburner to 610/1325/800 and scored ~6500, then went to 625/1425/825 and scored ~6800-6900, consistently. A LOT simpler than the method described above; just install the NVidia official drivers and MSI Afterburner and go. The OC stays after restarts into the Mac OS and back, and games have been running noticeably better. Temps are in the low 90°Cs, which I know is a little high, but I'm getting the unit exchanged for a 2.8GHz 15" i7 by Apple, so I dont care if I burn it out. Time to see how high this thing will really go...
EDIT: used 3DMark06 for benching, just so we're all on the same page as far as bench numbers goes.
EDIT 2: Just got my i7 w/ 330M today, will report back here if the same method that worked for my 9600GT (i.e., using the stock Nvidia driver) works on this new machine.
