    I have a 2008 Unibody Macbook Pro (Sig for details) that I want to overclock in Windows 7. I have already OC'd the graphics card to an insane level with only 7 Celsius increase in temperature, netting 40% higher FPS in CoD: MW2 and TF2. Now I want to up my 2.53 GHz C2D to 3.06 GHz. Please, no stuff like "aren't your computers exhibiting enough heat for you" or "you're going to void your warranty". Thanks.

    What clocks are you running on your 9600gt which are gaming stable?
    Also, what drivers are you using/ and using ntune or another program?

    I think with windows 7 you can oc your cpu as well. I have the 2.8 2008 unibody and can push it to 3.192 and even 3.265ghz which is pretty darn good. It even loads in @ 3.3 but I haven't done much testing at that point. That seems to be the limit with 1066mhz ddr3 memory but I have read that through bootcamp the apple chipset can recognize 1333mhz memory (which'll be downclocked to default in osx) but should be able to give you some more oc room on the cpu. (the 2.8 can probably reach 3.4 but I don't see it necessary to do all that much on a laptop, considering you would have to replace memory.

    Finally, have you done a thermal paste job on your laptop? I bought some IC diamond 7 and have seen some great results.

    PS: If you want to take your OC even further, I suggest you look into undervolting your cpu as well, which can further lower your temps. (It IS possible to undervolt AND overclock the core2duo's, but I assume it wont be by too much considering that the cpu is running higher than the default frequency. Either way, it should give you some nice temps. It is also possible to do that on the gpu but Ive only read about bios flashing, which I don't want to mess with on a machine that is dual booting. (If anyone knows a program that can do that for the gpu, please inform me :)

    Have you ran 3dmark06? Im interested to see your OC'd results, glad to see many ppl are knowledgable enough to milk the most performance possible out of such a stylish design. Nothing is impossible guys, don't listen to ppl saying your playing with fire. As long as you are in the desired temp range, nothing can happen. And apple will never find out ;P

    Ive been running my 9600m gt @ 650/930/1550 which is significantly faster than the even better 9700, playing sc2 on all ultra except shadows and shaders on high (25-30 fps is smooth for an rts game, @ 1440x900 of course) I am still experimenting with the best drivers so if anyone has anything to add I'd appreciate learning something new. Hope to have been a bit of help.

    oh how I would love to OC my GFX, its always on a low temp, no matter what u put it up to.

    I also wanted to flash my superdrive to rpc 1.

    but it seems both of these needs windows, which I don't have nor want to install really..

    My 2.66Ghz 17" cant reach 3.06Ghz..I suspect yours will have an even more difficult time :eek:

    for some reason I was thinking he had a duo, saw 2.5 and 3.06 and just assumed.

    Id say aim for 2.93. With the 2.66, its probably possible to reach 3.06ghz. Woot, update me on your gpu stats if you have time. (look at post #2)

    For undervolting in windows, check out rmclock and cpugenie(free trial can find the best voltage settings your cpu can support, great program)

    My GPU (NVIDIA 9600M GT, 512 MB) is running at 580 MHz core, 1180 MHz shader, and 970 MHz memory. It's been like this for over a year. I run games at max res, high textures, and high everything. If FPS drops I lower AA first, then A filtering next, reflections next, and then resolution. What program do you use to overclock your GPU? I use Rivatuner... Thanks everyone for the replies.

    I use nvidia ntune (or system tools, same thing)
    You can get it off the website, 6.06 is the latest version and should support cpu overclocking as well. But it seems as if you are running your shader under the default frequency of 1250??

    Btw the mem speed you are running is probably giving you a great boost. To my experience, it is also fairly hard to oc that high on the memory (with high core and shader speeds already overclocked to 600+/1400+

    I'm running Windows 7 64-bit, and nTune seems to cause a BSoD with this OS. I used it with Windows Vista, but I have to use Rivatuner because I recently installed 7. So, you use nTune for CPU and GPU? And do you know how to overclock the RAM speed?

    Okay, I'm sorry, they added support for nTune. YES OC'ING IS BACK!!!!! Thanks for reminding me.

    Well, Windows is incredibly inefficient with battery life on my Macs, so I just use Windows for gaming and Mac for everything else. As you can imagine, I don't game much on the move.

    UPDATE: After replacing my thermal paste and fiddling some more, I went to the realm of undervolting to try and conserve as much heat as possible. I was amazed to see that my 2.8 could operate at 3.192 with even a couple notches down from the default voltage, showing that it is way too high for that specific frequency (with my card). I ended up staying at a default frequency of 2.8 but was able to undervolt my t9600 from 1.162 vcore stock to a cool 1.050 vcore =] ( even tested it @ 1.037 but decided to bump it up for stability. with these settings cpu NEVER goes above 85ish even with heavy benchmarking. These heat savings even have allowed me to run my 9600m gt at 700/972/1600 (1650 would glitch for me) I dont have 3dmark06 anymore (feel its outdated) but have used numerous oc tools and made sure it is gaming stable. In the end, most games are more gpu dependant.

    Basically dude I wouldn't just because it might void your warranty. That's just me though, my two cents so to speak.

    i people

    i have a mbp 13'' 2010 with a core2duo 2.66 model p8800

    could i OC it under bootcamp?

    until now i was only able to undervolt it from 1.1500 (max operating voltage) to 1.0625 and increase the multiplier from 10x to 10.5x with throttlestop program.
    i tried to increase the voltage higher than 1.1500 to see if i could increase the multiplier even more but it seems everything is locked.

    what should i do? is there any way to do it?a program or increasing the front side bus speed perhaps(if possible)?

    second question:

    if i OC the ram clock would it make any diference in gaming?

    (my graphic card geforce 320m uses 256MB shared memory)

    i allready OC my graphic card with evga precision increasing the core and shader clocks (under controlled temps)and there is also an option to increase the ram clock but i don't know if i should do it. if by doing it i will get more performance?

    i want to know if i could OC my CPU because some games are more cpu demanding than gpu and so, it would be better a cpu OC instead to play such games.i would never oc both at the same time because it might be too much taking into account the temperatures
