Hi. I am interested in overclocking my 2009 Macbook CPU and GPU It has an Intel Core 2 Duo processor at 2.26ghz I believe it is the Intel P7550 It's 64-bit 3mb on chip shared L2 cache System bus is 1066 mhz It has an NVIDIA GeForce 9400M Don't know if this makes any difference but I have 2 hard drives inside the mac. One is an 80gb SSD with the OS and apps on it and a 750gb 7200RPM inside a hard drive caddy that replaces the DVD drive, and 8gb of ram (2x4gb) I have mountain lion 10.8.2 I am wondering how much I can overclock the CPU and GPU, and how I know if something is going wrong, if it is, and even how I do this in the first place? I hear these 2 are very overclock-able. The computer isn't as fast as I need it to be. And I was thinking of selling it to upgrade, but can't do that right now. Can anyone shed some light on this? Thanks. ---------- Just some info on what I use it for. I have between 1 to 4 (sometimes 5-8) chrome windows open in full screen, I sometimes run iMovie, and Pages and Keynote and Numbers and the App Store. Also Lightroom 4 (sometimes I have a few of those open at once). I have other programs running all the time in the top menu bar like menutab for facebook, twitter, lockscreen, little snitch, and some others. Apps like Instadesk, and itunes 11, Preview, Paintbrush, Spotify, Tweetadder, Firefox, Opera, Safari, and some others (can't remember) are usually running most of the time. I don't play 3D games, or any games at all really.
