Currently Being ModeratedApr 11, 2008 6:25 AM (in response to mviniegra)I hope it'll work, because since I updated the EFI and the keyboard my MBA goes so slowly, and also crash so often.
It's hard to work like this, also writting here, is quite difficult, and also I've some problems with the accents, they appear duplicated ( I've never seen this before..)
I'll try...thanks !MacBook Air, Mac OS X (10.5.2), 1,8 GHz Intel Core 2 Duo, 2GB ram...
Currently Being ModeratedApr 11, 2008 7:06 AM (in response to mviniegra)Did you do the recent firmware update? It has made my MBA run much cooler (see my forum post earlier today). I suspect Apple did something about voltage similar to what Coolbook does.
Currently Being ModeratedApr 11, 2008 7:39 AM (in response to Kirk McElhearn)I tried all the updates, some installed correctly, but others indicated that they has been already installed. (probably came out of the factory with updated software).
Nothing seemed to work. The problem was still there.
Anyway the coolbook settings I used were:
800 mhz at .9V
1200 mhz at .9V
1400 mhz at .9V
1600 mhz at .95
Temp limit: 75C
Now, does anyone know why this is working? I understand a little about undervolting the chip, but shouldn't OSX throttle the processor accordingly to temperature and load?
Why does the computer instead shut down a core, and why would apple say (looking at other posts) That this is a feature?!? Making my computer unusable...
Please apple FIX THIS!!! It seems that it is a very common problem with the macbook airs.
BTW: I do not have anything to do with the developer, but if I did I would be charging more then 10 dollars. IT JUST WORKS FOR MY COMPUTER.

Currently Being ModeratedApr 11, 2008 9:50 AM (in response to mviniegra)So ever since they announced the arrival for MacBookAir I was super excited about this product. Once it came out all of a sudden I heard negative stories left and right. a couple had to do with the overheating, freezing, the light on the keyboard wasn't that great and so on and so forth. I still haven't purchased it, I'm scared of facing my dream computer, and its not operating properly. How do you feel about the MBA, now that you have purchased? I'm about to go in a couple of days to buy one, but still very hesitant. What do you think?Windows XP

The same with Dell, IBM, Lenova, ...fill in the name
I've had angst with PowerBooks, iMacs, iPods, and MacBooks from reading here, but have had minimal issues.

Currently Being ModeratedApr 11, 2008 5:21 PM (in response to mviniegra)Just wanted to add my 2 cents. I have a week 8 Air that I've been mostly thrilled with having sold my core duo 2.0GHz MacBook. The main bugger for me has been overheating/ core shutdown issues under heavy video load. After working with Apple for 2 weeks. They isolated several Digidesign components (from Pro Tools 7.4) and Parallels Desktop components that were exacerbating the problem. The issue has been mostly solved EXCEPT for when playing World of Warcraft. BUT, updating to the latest Air firmware, using my podium coolpad, running SMC Fan control on max, minimizing my video settings AND using CoolBook have made me a happy camper. I can now run all of my apps and play my game as well without core shutdowns. I'm averaging 17-18fps in WoW now. My MacBook Air runs substantially cooler and quieter now with better battery life. So far my machine is stable @ all 4 frequencies (800/1200/1400/1600) @ .9 volts. Battery life has increased about an hour. Hope this info helps someone else and kudos to the tech dept @ Apple especially Brandon.New iMac Core 2 Duo 2GHz/ MacBook Air 1.6GHz, Mac OS X (10.5.2), 4GB RAM/ 2GB RAM
Currently Being ModeratedApr 21, 2008 6:38 PM (in response to mviniegra)It does throttle the voltage, and those are the "default" settings in Coolbook (best purchase I've made for my Air BTW!). Basically, using a lower voltage produces less heat. My minimum stable voltages are similar to yours, except @ 1600 my air is still stable at 0.9V. Apple's voltage settings are OK, but as Coolbook demonstrates, they can be lower. Apple's settings are "safe" - because minimum stable voltages vary across processors even within the same family - Apple had to be "safe." Coolbook allows you to customize the voltage settings to your particular processor.
Hope that helps.1.6 MacBook Air, Mac OS X (10.5.2)
Currently Being ModeratedApr 22, 2008 9:36 AM (in response to mviniegra)Oh wow, cool. Thanks for finding that. I had the same issue, my air would freeze then come back after 20 minutes. I hope Apple can address this problem, I didn't know it was limp mode.Too many to list, Mac OS X (10.5.2)

I haven't bought my MBA yet but I am copying this into my notes!

Currently Being ModeratedApr 26, 2008 1:24 PM (in response to mviniegra)I tried the CoolBook software & it works great. I have had issues with my Macbook Air freezing up & this small piece of software has solved this problem. I have been to the Apple Store 3X working with the Mac Genius to try to solve the issue. The MacBook Air still froze, even after the logic board was replaced. I hope that Apple will fix the problem soon for future users. For $10, this was an excellent investment.MacBook Air, Mac OS X (10.5.2)
