SMC Firmware Clamps Processor Speed?

I will agree with you on that point Phil however, I noticed that if the fan did not activate, the tempurture of the core cooled at a much slower pace than with the fan on. This is what I meant by my statement on the thermal design of the MacBook Pro which is indeed a characteristic of the outward case design on some levels. Sorry if I was too vague.

You will have to use a thrid party program like CoreDueTemp. It can be found at http://macbricol.free.fr/coreduotemp/ Good Luck!

I'm running the 2.0GHz with this new update. At 100.0% cpu usage I'm reading 90 off CoreDuoTemp. Freaky...

Running CoreDuoTemp v0.6

Temperature: 37C

CPU Usage: 16%

Frequencies
Mini: 1000Mhz
Maxi: 2000Mhz
Current: 1500Mhz

I'm hoping someone has a quick fix related to the recent firmware update problem. I just updated my MBP (has functional Windows XP partition, from which I'm sending this message...)with the new firmware and the computer boots into the Mac OS but then freezes. Used Disk Utility to repair disk, verify permissions, from the CD but problem persists. Thanks for your help, and patience.

Hi, I'd check your start up items. You can start up in safe mode and then remove them from your user options.

Well I feel lucky... My MacBookPro is from 04/21/2006 and is a 2.16ghz with 2gb RAM.

I have NOT installed the SMC update and while I write this I have had two "yes > /dev/null" terminals going maxing out both cores.

Initially Hardware Monitor reported my temp getting up to 84 deg. The fans came on and cooled it and it stayed there. Now almost 3 minutes later I'm at 77C with fluxuations to 81 and both cors are at 100% and have been for a while. Fans have slowed noticably indicating to me that it is taking care of business.

I guess I got a golden one. I have NOT opened the case and done the thermal goo thing either for fear of causing more problems.

I found that the problem is appear when you are NOT loaded the battery and connected the AC adaptor. The speed will loacked @ 1ghz

My unit is MBP 2.16G with 2G

I installed the update this morning and I've noticed a temperature decrease of about 4-7 degrees C, and CoreDuoTemp is reporting roughly the same clock speeds that I've seen for the past few days that I've been using it. Right now, I'm ripping a DVD in HandBrake and I've got 95-100% CPU usage at 2167Mhz and 73-75 degrees C.

I feel lucky to say that after installing the SMC update, my MBP 1.83 runs at normal clock speeds (1500MHz - 1300MHz when idle) and is a little cooler to the touch when running. I also noticed that the machine boots up faster, I don't know if this was just my imagination, but I seemed to get to the login screen much faster. Mine is an early MBP, and this seems to have eased my heat issues a bit, although I will have to see how this lasts over the next few days.

Just my thoughts.

I don't use Entourage, so I just gave Adobe Photoshop CS a click.
Same thing happens - 1500 at idle, after clicking on 'shop, 1333 for few seconds, then 2000.

Yeap. He's right. I just took off the battery and the speed drop to 1000MHz, put it back and it gets back to 1500MHz immediately.

It's a pity cause leaving the battery plugged in on AC is bad news for battery life....

i was totally going to suggest using handbrake. that is a good test for me. it will heat that sucker up and get them cores to crunching numbers.

This is with two terms open doing "yes > /dev/null" on a MBP15" 1.83GHz w/ 2GB RAM, 5400rpm 80GB HD. Revision A.

Hi-Ho, Hi-Ho, it's off to the Apple Store I go... 😟
