New macbook pro Overclocked to 3.15Ghz

lscangus said:
how can you do that?

With a utility which can adjust voltage and FSB, will actually brighten things up a lot. like the overdrive in i7. 3.1ghz during rendering!

Anyone knows any developer?

ayeying, you raise a valid point. I've seen about 45-50 extra minutes in windows for disabling a core, and slightly raising one of the core values.

Pair that up with 4gb of ram, and you would still have a fast machine that lasts just a little longer. This would be beneficial when one is watching a movie on the airplane, or something of that nature.

The computer won't lag THAT much at all with one core unless doing something CPU intensive. Web browsing, and word processing is NOT cpu intensive.

Click to expand...

Install XCode that came with your system. Its located in Disk 1 of the restore disk in "Optional Installs"

Afterwards, use "Onyx", goto Parameters and on the first section near the bottom install the "Processor" preference pane in All Users, not current. I have trouble with current user where the prefpane disappears for no apparent reason.

I can run a vista virtual machine using only 1 core. The only real time where I use the one core is in class w/ note taking. I can increase my brightness and still have the same battery run time.
 
What software are you using to overclock the fsb?

I'm also getting a 2.93 17" and would love to know how high this can be pushed.

MBP unibody 17" 2,93ghz

Hallo everyone!

This is f....... awsome! I'm actually from Denmark, and the time here is 1130PM a saturday night, and I glued to the screen!

Frag-master... you're awsome! :D

Can you or someone else make a "step by step" model how to do the things mentioned here in this thread - so that everyone reading this can also benefit from you hard work? This would be WIDELY appreciated!! :)

I'm think off a structual guide like this:

Mac Os X:
-------------------------
Q: How to save battery life when using the laptop only for word-processing and web-browsing?
A: Use disk 1 of the install disk -> install "Onyx" bla bla bla...

Q: How to OC ram?
A: Install this, do that...?

And other relevant stuff?


Windows Os X:
-------------------------
Q: How to OC the CPU?
A: Download XXX software from bla bla install bla bla...

Q: How much can a 2,66Ghz/2,93Ghz OC before it's dangerous?
A: X % before it's dangerous...

Q: How to set fans on a higher level for better cooling (when having OC'd CPU)
A: Install this, do that...?

Q: How to disable one CPU in windows for better battery time?
A: Install this, do that...?

Q: How to OC the RAM?
A: Install this, do that...?

Q: How much can 4GB/8GB of ram OC before it's dangerous?
A: X % before it's dangerous...

Q: How to OC the GPU?
A: Install this, do that...?

Q: How much can the GPU OC before it's dangerous?
A: X % before it's dangerous...?
--------------------------------


This is just a suggestion and some questions, that I could come up with?

Do you think you could be humble enough to share this with us "unexperienced mac noobs?

MANY thanks in advance!

Kind regards from Denmark

Does overclocking void the warranty?
Click to expand...

Yes...

The machines are fabricated and tested with the specifications, that Apple announces on their website... and these specifications have been tested and proved "reliable". If you OC you risk doing damage to the device because of more heat generated from variant factors: Ram, CPU, GPU etc.
 
How did you got to the conclusion that the MBP @ standard speed was not hot enough for you???
 
The cooling system in the MBP 17" is designed to handle the 2.93 GHz processor. Apple doesn't change any of the heat sinks or fans or cooling calibration based on the processor chip. The fans are throttled to keep the CPU chip below a certain temperature, they'll just turn on sooner in a 2.93 GHz machine.

Power comsumption for these processor chips is proportional to the clock speed. The reason the 2.66 GHz UMBP runs apparently cool is that the cooling system in that design is running at about 91% (2.66/2.93) of its basic capacity.

If either machine (2.66 Ghz or 2.93 GHz) is overclocked to 3.2 GHz, then the cooling system is running about 9% (3.2/2.93) over its basic capacity.

The 2.66 and 2.93 GHz chips are designed (mechanically) to handle the heat dissipation of the 2.93 GHz die. Actually, the chip pcackages themselves are good to whatever the the clock speed of the highest speed die made for that part. I think for the chips used in the UMBP 17" they go as high as 3.06 GHz.

It is unlikely that overclocking to 3.2 GHz will hurt the CPU. If you have a 2.66 GHz machine, it might be worth it. For a 2.93, I wouldn't bother.

The nVidia GPU is a different case. Apple typically underclocks the GPU chips by a significant amount (~20%). The cooling system for the GPUs is correspondingly derated. If you overclock the GPU to match the full clock capability of the chips (i.e., to the speed you'd see in a desktop or a gaming laptop), you risk doing serious damage. The GPU chips can provide the higher speed, but the heat sink and fans are not up to the task.

If you're going to overclock the video card, do like I do and get a laptop cooling platform, and keep a small desk fan aimed at the corner of the case that contains the video case. The more you cool the outside case, the better the heat sink is able to work.

I've had this preference pane installed for a while now, and I've also noticed it disappears randomly. Im starting to think that it's every time you restart / logout.

Well he obviously did come to the conclusion, and that's why he decided to overclock. Your Macbook Pro isn't going to explode into itty bitty bits just by overclocking. I overclocked my 8600M GT by as much as 40% and it barely raised the temperatures by 1 - 2 degrees Celsius. Apart from that, it's been 11 months and my 8600M GT still shows no signs of dying.

Honestly, I don't think that the Macbook Pros are that hot as people claim it to be. I found that the Macbook Pro is in fact cooler on the inside as compared to most other laptops. This is due to the aluminium acting as a giant heat sink allowing the heat to dissipate through the metal.

Maybe it's because the 9600M GT is severely underclocked?

Hmm. I just installed Xcode and had it "Quit unexpectedly" like 5 times before it loaded :confused:
 
Seems that all the UMBP owners on macrumors are either saying "hottest notebook ever" or "coolest notebook ever" when it comes to case temperature.

Is it environment surroundings? 2.66GHz vs. 2.93GHz? User preference?

User preference mainly I think. I bought the 2.66 because I knew I would not need the extra bump and I like a cool notebook :p

I'm not so sure about this..

I've been reading on another thread and the person there said that the card is underclocked UNTIL it needed, then it clocks itself back up to stock speeds.

He ran benchmarks while playing games and the speeds were all normal speeds not underclocked.

I guess the card does this to save battery life / keep the system cooler.

I guess so. However, when I installed it into "All Users" it remains in place. I only have one account on this system so its fine for me.

I installed XCode because its required. Onyx is what I used to get the prefpane installed.

Its been fairly cool here (Mid-60s Deg F max ambient). I get normal temperatures on idle and on load. Well within the limits.

All nVidia cards, excluding Desktop Cards, should have this ability. nVidia calls it "PowerMizer". Basically, it underclocks the video card when you don't need the power during times such as Watching a normal standard resolution movie, word processing. It clocks to mid-range when you do something more intensive such as 720p/i HD watching or such. Then it clocks to max when you start up 3d intensive programs such as games/modeling.

Exactly. Macbook Pro's get a lot of stick for being "underclocked" and I think that's just normal. When you need the power they will give it.

Hmmm i need help overclocking........

I have the new Macbook Pro 17 2.93 4gb Ram with Windows 7 running using bootcamp. I downloaded Nvidia tools (looks like an advanced NVidia control panel) to try and overclock the gfx card. Both times the Macbook crashed.

Trying to put the clock up to about 505 to see if it moved made the screen freeze & putting it to 600 made the screen just completely crash out with some buggered black screen.

Macbook is fine..... How are people successfully clocking the GPU and with what prog?
 
I'm trying to find the download for these system tools that supports the macbook pro.

Can someone please post a link to which one your using?

Many thanks,

Regards,
Simon
 
RE bumping the "Question --> answer" reply...

Would you guy, who succesfully OC'ed your macbook pro tell us, what program you used, what you did and so forth?

I tryed using Nvidia Ntune, but my MBP just frose and gave me the "blue screen"... every single time I pressed "agree" to the terms and conditions in the Ntune...?

I'm using a "cracked" vista ultimate 64bit... does this have anything to do with it?

Best regards
Denmark
