Low Core Duo Temp Readings

When i run core duo temp, and have my processors about 80% loaded playing 1080p videos my core duo temp reads about 27C. I know this cant be right? Is anyone else experiencing these super false readings??
~Ryan

how would you reinstall?
I tried and it said it was already installed...

Core Duo Temp Question

I just got my replacement macbook from apple and so far it's working great.
Something odd I noticed is that with any temperature monitor program I use (core duo temp is one of them) the temperature seems to be locked at whatever it was at startup. It doesn't change even while running yes in two terminals. The fans to eventually turn on but for instance, I've been maxing out the cpus for about 10 minutes now and the fans are going full blast but my temp monitor is stuck at 32C.
It a week 31 White 2.0 macbook. I wonder if something changed in the temp. interface on a new ones or something is just not working.
Could someone with a week 31 or higher report back what your temperature monitors are doing.

How does the physical temperature feel on your MacBook case bottom to the touch and do your fans come on noticibly (audibly) when using the MacBook for more than an hour?
Perhaps the sensors changed on the latest models or some had the sensors forgotten to be plugged in. I hope an 'in production' logic board/CPU design revision didn't overlook the sensor design somehow. Apple would never reveal publicly an in production revision; only a part number change would show up a supercedure.
Perhaps many more week 30 and later owners will report in here or on the MacIntelTemp site. (I don't recall the URL)

Core Duo Temp program

I have read about a program that tracks the temp of the processor in this forum. Where can a person download it?

Two possibilities:
Core Duo Temp

Core Duo Temp Frequencies?

Ok what is the deal with the frequency thing in Core Duo Temp? it says like Minimum 1000 Mhz and Maximum is like 2000 mhz is it bad that mine is running at 2000?

These mobile processors use stepping technology to save battery. That just means that when you don't need as much processing power, it lowers the frequency to save battery power. You'll notice that if you open a program that uses a lot of processor (try a flash app, which still runs under rosetta) and the processor will pop back up to 2ghz.
It's nothing to worry about.

Core duo temp reads 74 degress Celsuis

thats like 150 fahrenheit
not normal right

coreduo reported much higher temps than temperature monitor. i recently installed that and my idle temp has 'gone' from 65C to 55C or so......
also, coreduo would screw up on occasion, giving me the "retrieving information" message and not actually getting anywhere.
i feel that TemperatureMonitor is a much better program, for it's stability, also the feature of viewing seperate core temps, also HD temps

Core duo temp...

ok i downloaded it for the first time and i noticed the temp was 58 degrees. so i was like wow thats not bad...then i saw the C. celcius. so i changed it to farenheit (obvioulsy the metrics we use in the USA) and its 136.4 degrees. isnt that really hot? why does everyone go by C? does the lower # make everyone feel better? im confused.

Steven, the Centigrade temperature scale is used in much of the world instead of the Fahrenheit scale commonly used in the U.S.
But even in the U.S. the Centigrade scale is used in science and engineering.
Every computer chip has operating temperature specifications, a range of temperatures within which it will operate properly and meet specifications for its operating lifetime. The Intel CoreDuo used in the MacBook Pro is specified to operate safely at temperatures up to 100 C (212 F).
Your computer has sensor circuitry and associated software that keeps the CPUs from exceeding the maximum safe temperature.
Don't be put off by the "boiling water" temperature. Doesn't really mean anything. Your home heating furnace likely operates with a really hot gas or oil flame. But no matter how hard it might try, your furnace can't heat your house to such a temperature (unless it sets your house on fire).
Your CPUs cannot heat the computer's case to 100 C; the case may feel very warm but you cannot receive a burn by touching it for a moment. I use an aluminum tilt stand whether my computer is on my desk or in my lap, and am perfectly comfortable. Yes, I can use the MBP as a laptop and in a way that follows Apple's guidance on page 107 of the user guide.
My MBP doesn't have a heat problem. It operates very conservatively inside the temperature specifications. The portions of the computer that I need to touch to operate it -- the keyboard, trackpad and rest areas left and right of the trackpad -- stay comfortable for me to work on it all day (and I do work long hours every day). That's also true of my hard drive. It stays comfortably inside its design specifications for temperature.
My MBP doesn't need the "grease fix" as it operates very well as designed by Apple. I can easily generate temperature graphs that compare with those posted for computers that have had thermal grease reapplied, displaying temperatures lower than some of those. I feel no need to void my warranty by disputing the design and manufacturing specifications certified by Apple's engineers.

Core Duo Temp guage in Windows XP?

Hi all!
I finally pruchased the MacBook today and I install bootcamp and Windows XP. I was wondering what tool y'all use to guage the temp in XP?

Try RMClock or CPU-Z

New Core Duo 2 Macbook benchmarks?

are there any new Core Duo 2 Macbook benchmarks out yet?

Well, 46°C idle do seem high, even for the 4MB Core 2 Duos. I think with the stock cooler you should idle around 38°C to 40°C, depending on your ambient temperature. You can overclock your CPU moderatly without burning it, and if you dont increase the v-core, things are pretty safe anyway. Just make sure your memory can handle the speeds, but if you set the divider to 533MHz (1:1) 300MHz for example shouldnt be a problem. Set the v-dimm (RAM voltage) to 2.1v.
Your CPU temps dont have anything to do with the PSU you use. Its more about the other components in your system and your airflow. Do you have a case with fans sucking air in? If not find some fans that fit into your case (lower front, rear). Using the stock cooler a better airflow will give you better CPU temps immediately.

Has anyone with an Intel Core Duo got lm_sensors to work?

I keep getting a message about no sensors being found. I've followed the wiki, but I just can't seem to get it to work for my Core Duo.
If you have got it to work, can you please let me know which modules sensors-detect told you to load?

I have it working on my new system.
I tried to just build the driver for beyond but it would not work so I found a patch and rebuilt the kernel. An updated patch has now been sent to iph for inclusion in -beyond.
I then built lm_sensors-svn from the AUR and low and behold:

Overheating MBP Core Duo

Folks,
I know that the original Core Duo MBP's like mine ran hot. I'm accustomed to that. My MBP typically idled at about 46*C to 56*C. I had a problem about 2 years ago where it would spike to 80*C+ & it was suggested to me that I disable Spotlight. I did so & thereafter the only time it ran in the upper 70's to low 80's was when I was doing heavy calculating, like ripping movies.
However, lately it has been climbing into the low 80's for no apparent reason. Whereas, in XP in runs in the 40's to 50's.
I updated to 10.6.3 in the lame hope that it might have some moderating effect, but no.
Can anyone offer an explanation? I'm sure that letting this machine operate at these temps for an extended period will do it no good.
Thanks for any help.

S.U.
Yes! I checked the ActMon & one app was taking up way too much CPU usage. I didn't recognize the acronym so I Googled it.
Turns out it was iAntivirus. Once I disabled it my CPU temp dropped immediately to the high 40's *C. 45*C at the moment.
So, I did a little research & it seems many others have had the same complaint. I uninstalled iAv, installed ClamXAv & all seems fine now.
Oh, and just as an aside...the MBP sits on an aluminum/plastic cooling pad with its own fans & I keep it (the MBP) spotless & dust free; outside and in.
Thanks for the help! Cool!!
Regards,

Second hand Core Duo or new Core Duo 2?

Ok, I am really in doubt at this moment. I can buy a second hand Macbook 1.83 Core Duo with 2 Gb mem. for EUR 950 which seems like a good deal to me, but... should it be a better choice to go for the second generation Core Duo processors of the current Mac Books considering the upcoming OS? Or is speed more about internal mem than CPU? Can anyone figure this one out for me?

We really can't answer this one for you - it really comes down to personal preference and what you are planning to use the laptop for. Check out the technical differences between the two and think about whether or not the differences are really important to you. There are three big differences, off the top of my head:
- Core duo is 32-bit, while Core 2 duo is 64-bit.
- Core 2 duo ships with an 802.11n capable wireless chipset
- Battery life seems a bit longer with Core 2 duo, and it tends to run a bit cooler.
There are quite a few more minor differences between the two (and several not-so-minor ones that I'm forgetting about, I'm sure). If your price for the core duo is significantly lower than the newer core 2 duo, and if the differences between them don't really matter to you, then I see no reason not to go with the cheaper laptop.

Random Shutdowns on a MBP Core Duo, Suggestions/Help would be great

I've had two random shutdowns of my mac since purchasing it back in August. The first happened on January 11th, when it said it was at 11-12% power. The second happened about two weeks later, at 23% power. I've been looking around these forums and other pages, and haven't really found anything that has helped so far.
Details of the first crash:
Open apps- Firefox (5 windows, two had about 20+ tabs open, the rest were single page, and yes, I know it crashes often with that many), Camino (1 window with 5 tabs), and Word 2004, as well as Quicktime open to the iPhone stream.
I had an USB key plugged in, to which I was saving my Word document.
So I was working in Word while in front of the TV and during an interesting bit, didn't do anything for a minute. So, like the many times earlier, it slept the display to conserve power (in "Better Energy Savings" mode). I moved my finger on the trackpad to wake it back up, and it turned back on the backlighting, and then stopped. I thought it had just went back to sleep, but after a few key presses and a check of the light that usually pulsates when it's sleeping (plus the USB key , I found out that the computer had turned off. I let it sit for a while, and when I plugged it back into AC power and turned it on, with my USB key still plugged in, and although it booted to my desktop, the Finder never started (so no desktop icons for anything), unplugging the USB key fixed this and everything returned to normal. I then installed the only update I was missing, one for iChat, restarted, and continued working.
In the second incident, I only had my browsers open, nothing external plugged in, and my displayed was dimmed to the third darkest level. When it was at about 23% power, it once again randomly shut down. This time, I attempted to turn it back on, and nothing happened. After plugging it into AC power, it turned on and once logged in showed a very low (2-6%) power, so I guess it was reporting the power incorrectly?
Anyways, went back to look at the battery exchange on Apple's website. I had checked before when they started it, and was pretty sure mine wasn't covered, and a second check confirmed that. My Mac's serial is W8618091VWX, which isn't covered by the recall.
So, I have a few questions:
1. Is there a toll-free number I can phone Apple (Canada) at? The only number I've found seems to be only free for those who bought their computer in the last 90 days, which I'm no longer covered by, and haven't been for a while. Talking to someone at Apple would be good.
2. Otherwise, if I took my computer to an Authorized Service Provider, would they be able to take a look at it and answer some questions? I bought my MBP at a London Drugs and they aren't service providers, so how much would it cost to do this?
3. Is there a definite cause for these random shutdowns? It seems to vary among other people, so it would be helpful if I could try something to eliminate one of the causes.
4. Does Tiger report battery levels pretty accurately? In the past when I reached 6% I got a warning and was able to plug it into AC power and had no problems.
Thanks for any help you can provide.

I had this problem of RSD fixed for a while after having had the battery replaced by Apple, till yesterday, when the MBP suddenly experienced a shutdown during a meeting presentation, while it was connected to the AC power. At the first restart, as coming back from a stop-mode, for a while appeared a warning of low-battery level, with battery level indicator flashing red and showing the empty icon but with a 86% of charge level and a new shut-down definitely put the MBP out of service, no way to have it functioning again. Obviously, AC power was OK, no problem with the microphone or the projector ( I was at the podium of an international meeting) and a lucky precaution ( double save of the same presentation on a friend's twin MBP, that worked correctly) saved the job.
Then, a couple of hour later, my MBP started up normally and everything works fine, with or without MAGsafe connected to AC power, almost up to now.
I've read the post with a link to the procedure for resetting the power controller chip on the mainboard, I'll do it in a minute, hoping that this will help.
Any further suggestion?

Should I upgrade Intel Core Duo 1 Mac Mini (2006) to Snow Leopard?

Okay I have a 80 GB Apple Mac Mini with Intel Core Duo 1 proccessor that shipped with Mac OS X Tiger (10.4.7) currently running 10.4.11 that I want to upgrade to either Leopard or Snow Leopard in a few months just in time for Christmas which I acquired in September 2006. It was the first Mac Mini model to include Apple's Front Row software and shipped with an Apple Remote (I know Macs don't ship with Apple Remotes anymore you have to buy them separately) and am now pondering an update. I've heard some things about Snow Leopard not working so well with older Macs even Intel based Macs that are only 32 bit.
Thing is I just got a new MacBook Pro that shipped with Snow Leopard and it seems to run fine on the MacBook Pro except for the fact a few applications I wanted to install wouldn't work with Snow Leopard like Google Desktop for Mac so was wondering if I should update the Mac Mini also to Snow Leopard. I do not particularly like how Apple removed the transcoding features to export video from one format to another in QuickTime X that was available to QuickTime 7 Pro users (actually reinstalled QuickTime 7 Pro on my new MacBook Pro so I can still use that despite QuickTime X being installed) but like Expose integrated with the Dock Menu that's new in Snow Leopard and features like Cover Flow built into the Finder (available also in Leopard along with Spaces) so if I update the Mac Mini should I update to Snow Leopard or Leopard?
This is a 2nd generation Mac Mini (the 1st generation had PowerPC chips) with Mac OS X Tiger and I've heard some negative news about upgrading Mac Mini to Snow Leopard so I want to get some more feedback on whether or not its worth it. The Mac Mini came with iLife and iWork 06 versions but updated iWork to iWork 08 Family Pack. Still have iLife 06 though and am still running iTunes 8.2.1 on the Mac Mini.
I use this computer as my main system for syncing with iPods (I have a 5th gen video iPod and a 2nd gen iPod Touch that I sync with the iTunes Library on my Mac Mini which includes videos purchased earlier from iTunes Store and music purchases as well as TV purchases) so don't want to risk messing up the system with a Snow Leopard update if it is going to cause problems doing so. If Snow Leopard is not good for the Mac Mini will just update to Leopard and stick with Mac OS 10.5 Leopard on this system.

I upgraded my mac mini 1.5GHz core solo to a Core 2 Duo 1.8Ghz in order to run most of SL's 64 bit stuff. I bought a pulled Core 2 Duo from ebay for $29 and it took about 1.5 hours to do the switch.
The main downside with the 2nd gen Mac Mini is the kernel cannot run in 64 bit mode due to a 32 bit controller that cannot be upgraded. Yet, booting into 32 bit kernel is SL's default setting and as you may have read in articles when SL came out, relying on a 32 bit kernel does not slow down use of 64 bit apps. I maxed RAM to this mac mini's 2 Gig limit years ago which is a good thing for you to do too.
I am happy to report the upgraded Mac Mini runs much faster than originally thanks to the 2 gig of RAM and the Core 2 Duo chip. Installing SL made it run faster still and consumption of memory for apps is lower (smaller pipeline requirements with faster CPU), and about 14 GIG of HDD space was recovered since I did not reinstall Xcode tools. I can now encode 1.5 hour long video files that used to take overnight processing time. CPU runs hotter, up to 89ºC, but usually run only about 10º higher on average than before while fan rev's not noticeably more than before between 1500 to 1800.
If you are not comfortable to upgrade the CPU, I think you will still find some benefit to SL for $25. Alternatively you could sell your Mac Mini on ebay (these 2nd gen model are popular for those want to do the upgrade) and use the proceeds to buy a refurbished current gen Mac Mini.

Using new battery on old 2.16 GHz Intel Core Duo

I am in a remote location, under a deadling. My 2.16 GHz Intel Core Duo MacBook Pro battery cable finally went south. I'm in a studio with half a dozen brand new battery units ... for 2.66 GHz Intel Core i7 MacBook Pro's.
Can I use the battery from a 2.66 GHz Intel Core i7 MacBook Pro on my older 2.16 GHz Intel Core Duo???
All ears,
Ben

As I wrote above, there is no possibility of using one of the new batteries in your old machine: it absolutely won't fit. Furthermore, removing the battery from one of the new machines will void the warranty on that machine, so even if you could contrive a wiring harness to connect one of the new batteries externally to your MBP, there would be good reason not to do it.
And if you did, there is no way to predict how the charging system in your machine would respond to the incorrect battery. Would it be charged at all? Would it be charged only to the capacity of the battery specified for use in your computer, which is far lower than the capacity of the new battery? Would the SMC in your machine recognize the battery and distribute the power from it correctly? The answers to these and many other related questions are anybody's guess.
So the solution to your immediate problem will be to move your work onto one of the newer computers, finish it up by the deadline, and order a new battery for your own computer.
