I'm asking good settings for my MacBook 2,2Ghz Core Duo & 4Gb RAM.
How many different speed i should use?
I mean like this,
Quote:
800 mhz at .9V
1200 mhz at .9V
1400 mhz at .9V
1600 mhz at .95
Many different settings, or just 2, etc?
I just bought coolbook for my two and a half year old White Macbook. What would be the best settings/courses of action to keep my book from overheating and be able to comfortably play streaming vid. on a 23" monitor?
Don't know if that last part really makes a huge difference.
I have read a few isolated postings about people with Rev B using CoolBook.
If you do that what is the extra battery time you get from your MBA Rev B with CoolBook installed?
I saw a single post somewhere on these boards about something called "coolbook" which is a utility that undervoltages (is that even a word?) the chip to make it run cooler.
It's $10 to give it a try. Wonder if anyone with fan issues would give this a try to see if it changes the heat/fans much?
Google coolbook and you will find it.
Now I have these settings with coolbook:
But there is just no difference in temperature or fan speed. Now iTunes, Firefox, Adium and Coolbook are open but as soon as I start to load some Webpages (Engadget, Spiegel.de, etc...) the fan runs a lot faster and thy CPU has about 55�C.
So, software update today addressing the core shutdown issue.
I turned off Coolbook (uncheck "Coolbook Active"), rebooted, installed the update, rebooted, turned Coolbook back on and rebooted. By now, my machine was pretty warm, so I put it to sleep for a couple minutes.
Then I ran 10 minutes of Youtube videos. My max temp was 66 degrees. My fans stayed low for the first couple of videos, then slowly crept up to 4500 RPM over the course of the third video. I think they would eventually reach max fans, but it looked like another 10 minutes or so to get there.
Compared to before, the fans definitely came up much more slowly, so that's good. Otherwise, everything seemed to run normally for me.
Environmentally, the ambient temperature in the room is about 75 and I have the machine on my lap (so some of the vents are blocked).
In my opinion, the update looks good. Despite the warning in the update, Coolbook still works fine and still provides a superior heat management technique (by generating less heat in the first place).
i have a very big problem after update tp 10.5.5 in my macbook air.
i do the update with coolbook active.... and when restart... the system dont pass over 800mhz at 50�C and all the system go very slow.
i tried to active again coolbook, restart, but coolbook dont work....
so now i have that problem.... my 1,8 macbook air dont pass over 800 mhz...
what can i do??
I've just installed coolbook and fiddled around withe the settings etc, and restarted.Do I need to open coolbook every time I restart the MBA?Do I need to have the application running all the time, or do I just leave itclosed? (i guess if the answer the question 1 is no, then the answer to this is no as well!)Finally, is there a way of keeping the icon in the menu bar without having the actualy application open (assuming you don't need it open all the time)? I like seeing what temp it's currently at
View 24 Replies View RelatedI have a Macbook 2ghz core duo (non core 2duo) and the fan works loud. What is the best setting when I use the app "fan Control" or "coolbook"? I don't know which app is better?
View 6 Replies View RelatedI'm just wondering if the coolbook work well with new macbook air 13".
has someone the working beta version? and can someone send me?
I run 2 instances of yes > /dev/null in the terminal windows and the coolbook temperature rises to 100 degrees Celsius. In istat pro its 105 degrees Celsius for the cpu? And of course its downclocking to 1200mhz. If I use the lowest voltage in coolbook the temperature will reach 92 degrees celcius, still really high. I'm only stressing the CPU, wonder what happens when I also stress the GPU. It seems the air is really not capable of this 'high-end' processor and gpu, I wonder if the rev2 of the air will be any better.

View 16 Replies View RelatedCoolbook doesn't work after updating from 10.6.1 to 10.6.2. When I open it, it says "This update requires a reboot" no matter how many times I reboot. I can't use it, and I also can't uninstall the driver to reinstall it and see if that corrects it. When I try to uninstall it through the preferences pane, it says "failed to uninstall Coolbook."
View 9 Replies View RelatedThis gets asked a million times on a daily basis I expect, so sorry about that! I've read the upgrade section which is very helpful but I was looking for some recommendations / advice on what HDD&RAM upgrades to buy. I was looking at a seagate momentus (ST9500420ASG) 500GB, 7200 but when I googled the model number, the first thing that came up was a post on the seagate forums regarding incompatibility with the Mac due to the fact this hard drive has a free fall sensor which apparently conflicts with the built in sudden motion sensor. Anyone have any experience on that? I need a drive that will run at 7200rpm so this checked all the boxes for the price but could be out now? I have read the SR 3,1 will take 4GB of ram so I was just looking at the dual 2GB corsair value pack (VS4GSDSKIT667D2).

View 8 Replies View RelatedQuick question guys, I currently have a Powerbook G4 17 inch with 1.5 Ghz, 2GB of RAM and 80HD. I love it, with the full powered RAM it flies, but, I HATE ITS SIZE, i mean its not that portable. I have at home a Mac Pro so the power im looking for i have it on that machine. I wanna try and change my Powerbook before the new ones arrive because i need PORTABILITY. Is it really a big of a difference? I mean i dont need the "power" of the powerbook because i have the macpro at home. With 2 GB of RAM, will a macbook (lets say the current ones) be really faster and more efficient than my old PB G4? I like the 17 screen but i need portability so bad! what do you guys recommend?
View 2 Replies View RelatedI have a 2.2Ghz Macbook Pro 15" (2007) that suddenly can't get past the startup screen and ends up with a kernel panic and the You need to restart message. Happens 100% of the time now. I had Leopard on it when it started kernel panicking. I managed to boot from an external drive and installed Snow Leopard, but it started okay once or twice, then started having the kernel panics at startup again. Tried SMC reset, but no go.
I then tried going back to Tiger, thinking it might be a problem with the RAM. Tiger actually installed okay, and after it worked okay for a bit (2-3 times, maybe half an hour), I tried to install Leopard again. And got only kernel panics. And I can't install Tiger now either.
It occasionally starts up from an external disk that I use for installs (has Leopard and Snow Leopard on it), but that's not 100%. And I can't even get thru an install now. I started up with it in Firewire Disk mode, wiped the drive and cloned a system from my iMac, but even though it seemed to go okay, when I shut it all down and tried to restart the Macbook Pro, I got another kernel panic. Any ideas? I've switched 3-4 different RAM modules, and I don't think they're ALL bad. But no go. I've changed hard drives too.
Seems weird. I mean, it doesn't seem broken, as it starts up, goes thru the startup screen, seems to pause a bit and, instead of going to login, stops with a kernel panic. I assume it's HARDWARE, not software. But hardware problems are usually the RAM, sometimes the hard disk; and if the MBPro doesn't start up at all, then the logic board is probably fried. So what else can cause these kernel panics? A bad keyboard/trackpad (top case)? Bad PRAM battery?
I've been trying to keep track of how my 2ghz unibody Macbook uses its RAM, and I've been curious as to why after some time it reports that I have as little as 30 MB of free RAM left. It obviously reports that the rest is in use, but the numbers just don't add up to 1.9GB of used up RAM. What is my computer doing that is not being reported, and how do I get it to stop? It has made my machine noticeably slower. I've posted a screen shot to illustrate. It may help to know that I had been a Windows user for years. In Windows we can launch msconfig.exe to manage which programs get to run in the background and at start up, and from there we could decide to shut down programs that check, for example, for RealPlayer updates and other completely unnecessary executables. Can someone give me a run down of what I can safely eliminate from my processes in my Macbook, and therefore keep more RAM free at all times?
View 2 Replies View RelatedAs title, can it be done ? officially it says no, but iv read around some forums where people are saying it has been done in a 2x 2gb config, I ask as architecturally core duo can support 4gb and does on old IBM laptops of the same t2500 processor (2ghz), so im asking if there is anyone that can confirm this for me ?
View 3 Replies View RelatedI'm starting to get the upgrade itch again, with the added "pressure" of my cousin looking for a new laptop that will last 2 years or so. She's looking at the $999 MB, but my Santa Rosa 15" MBP with almost a year's worth of Applecare left seems to have roughly the same specs, and I'd sell it to her for ~$500. I'm still trying to figure out of it's a good idea or not, but I'm leaning ever-so-slightly for the new laptop (15" mid/high, possibly 17"). As they say, always put together a pros and cons list, so here's mine:
Pros:............
I have a 2.2Ghz Core2Duo BlackBook with 4GB of Ram. When I view large PDF's such as magazines, they are quite choppy when scrolling. If upgrade to the 13" MBP will I see better performance in this area?
View 8 Replies View RelatedI bought my MacbookPro two years ago, september 2007. In june 2009, as I didn't need the computer for some time and the warranty was about to expire (it's "two" years in the European Union, the second isn't covered by Apple, just by the physical store you buy the computer at) I thought I'd take the computer to be checked, because it had had two problems for some time: the Superdrive won't record dvds (it never did) and lately the left fan was very noisy when it turned faster.
It took a lot of time but they replaced the superdrive and the left fan. However after the replacement even though the fan is fine, the superdrive wouldn't still work with dvds, of which I don't care anymore because this is the big problem: Since then, the screen sometimes gets crazy and does as in the video I link to: [URL] It all stops when you move the screen a little. Furthermore sometimes a vertical line appears like half an inch from the left border when moving the screen. It all appears randomly................
Wanting to upgrade my RAM and need to know how much it can handle. HOpefully someone can answer this for me
Info:
MacBook Pro (15-inch Early 2011), Mac OS X (10.6.8)
I've had my iPhone 3g 8gb since June 2008 and loved every minute of it. It's been through it all. Even dropped out of a helicopter last week. Ok it was only a fall of around 6ft but still, it sounds epic. I've recently gotten a hold of a Macbook 2.1 2ghz 13" white. It's a late 2006 model and the drive has failed. I planned on replacing the drive myself and apple have kindly sent me the recovery dvds free of charge. Tiger 10.4.11. I read on here about the extended replacement scheme for failed drives on here last night and I think I qualify, however I may still put my own drive in it. Out of my stick just to get things moving along. Once that has been done I plan on upgrading to snow leopard 10.6. I'm curious to find out what drives this machine will support and how much ram it will take and benefit from.
View 3 Replies View Relatedwhat I imagined was a documented 8600GT nVidia issue with my SR MBP (purchased in April 2008 without Apple Care, d-oh), turns out to be a different issue altogether. The display gets distorted and it seems as if the LCD needs a v-sync controller. I have posted a video of it here[URL]. If I move the LCD slightly the distortion will go away. But it inevitably returns after a while. It gets unusable for that period of time. Oddly enough I can go hours without this problem manifesting, and then hours when this problem doesn't go away.
My recourse has been to connect an external monitor to the MBP, and it works great that way. So I am pretty convinced that it is an LCD/Cable issue as well. The Genius seemed to believe it was an LCD issue as well, something about the cable being torn or stretched or something. He quoted an amount ~$650 to get the whole assembly changed. Here's my dilemma: this is my work machine, and I can't afford to have it gone for a few days/week. Is there anything I can try at home before handing it to Apple for repair... like try and reseat the cable... I have opened the MBP in the past to replace the HDD. Should I even bother to get it repaired, if I can't fix it myself, or should I just save the money and get a new MBP?
I have had my MacBook Pro now for a little over 2 yrs and I was very frustrated I could not change any print options in any application. I know that the Triangle button expands print options screen but when I do, I have only two print choices. It gave me Standard or Page Attributes in Office and any other App it is Standard and Last used settings. I can't print in Draft, Best or other setting because it does not even give them as a choice. I have two high end color photo printers, Canon i9900 and Epson Photo series and an old HP830 series. Any app I tried to print from and the same thing. I tried to capture the options on the choices but it would not grab that part of the image but here is my screen shot. I searched many forums and I still get the same answer so something else is not letting me change things so I figured best to ask since I am a 20 year win user now switched to Mac. Well right after I posted this question, my wife found the answer. I never though to check the application NAME in the print setting screen. Example, in the screenshot I am using Preview. I never thought to hit the up/down arrow next to the Preview label and wouldn't you know, that is were the quality and several other settings were. I felt pretty stupid that it took 2 years to figure this out but if I posted the answer maybe someone else will not have to take as long as I did to change their print quality!
