Anyone Overclock?

So do you guys over clock? I dont see the point too much unless your playing games though I could be wrong. And as fast as OSX is i see even less of a reason, but again, I could be wrong.

 

no need to OC for now. The speed is still good enough for me.

 

I tried overclocking my MBP GPU in Windows briefly... but the gain wasn't worth the risk and heat increase.

 

haha!! gotcha!!! Im sure someone would have overclocked either the cpu or the gpu and would come here complaining about the heat!!I would'nt advise anybody to overclock the cpu or gpu. highly heat hazardous.

 

yeah gotta agree with you. not good enough results for the small gain. was just curious.

 

I've been consistently overclocking my CPU in Windows, it runs at 2.6Ghz(I haven't tried any higher) and runs relatively the same temperature to stock levels. I am doing some undervolting on the lower VIDs.

CPU Overclocking is not doable on OS X as far as I know yet, but given the chance I would definitely try. LOL I despise you guys who say "fast as OSX is" or "wasn't worth the risk and heat increase", any increase of speed is an increase despite whether you see a difference or not. If that was your mentality, would you settle for a slower 1.8Ghz if Apple made one?

 

umm.. I haven't complained, and likely the only one on this forum that has overclocked both CPU and GPU on a unibody MacBook.

+ I have cooler temperatures than your stock system in Boot camp even while overclocked.

 

Notice that the environment also plays a good role on the temperature. i see that you live in canada. it's cool over there. so the notebook would definitely run cooler.

 

LOL are you serious?!
Like any normal office worker, I'm indoor most of the time in a 21-23 degree ambient environment, it's NOT like I'm out computing on my porch during winter weather, we have heating here too what do you think we live in? igloos?

On top of that, I have the Speck case, which does increase my temperatures slightly so if anything I should be in worst conditions than you.

 

haha sorry but hes got you on that one Luke lol

 

nah never overclock any of my computers (desktop or notebooks) (mac or windows).

not worth the risk or hassle. cant be bothered.

 

I really don't get some people who post their opinions about a subject matter but yet, the thread is about actually doing it.

There has been a few people who has successfully overclocked their Unibody Macbook Pro just like I have using the same method, some over at Macrumers and on Ocforums. All are within Windows Vista only.

I've been able to google a EFI firmware mod method for OS X, but not sure of the procedure or what's needed to get it working. Any ideas?

 

I overclocked my GPU and undervolted it so it runs a bit cooler and a bit better via hard clock in NBITOR, and CPU Overclock/undervolt VIA RM Clock

 

are you targeting anyone in particular?

I think overclocking without undervolting is a bit dangerous due to the laptop heating up.

 

No, I'm not. Just pointing out the obvious. There are just too many personal opinions like " I dont do it because of such and such" which add no value to a thread like this. Let's leave personal opinions aside...

If you don't understand the concept or have inner fears of destroying your machine, then your not the type of user that should be thinking about overclocking in anyway. If people think that overclocking is a simple and painless task, it's definitely not, you need to identify, research, test and test and test your results or else you'll be left with a unstable machine.

Although heat is an issue, it will not break your machine as there are internal thermal switches built-in the CPU, an overheating CPU causes throttling in your laptop which is a counter measure. Google heat throttling, this has been implemented since the Pentium 4 days. Suggesting undervolting actually shouldn't be recommended as this adds another "problem" to the formula, if you're increasing frequency that extra voltage that was originally provided might be needed to stay stable. You only start doing undervolting once your overclock has been tested as stable, then you start notching the voltages down to lower temps.

 

thanks. i've tried undervolting before but it rendered my machine unstable. I preferred reverting back to stock voltages.

 

You need to use a program like CPUTest to test for stability at each of the multipliers/frequency settings. See Undervolting Guide if you haven't already, although it's for PC, the concept is exactly the same, just different programs/applications to do the same thing.

Every notebook can undervolt, it just depends by how much and that's a luck of a draw.

I think I need to create an official MacBook Under-volting Guide.
