Core 2 Duo CPU whine.

Hi everyone.
I am close to purchasing a MacBook Core 2 Duo for my brother and I would just like to know how much of a difference there is in CPU whine between the Core Duo and Core 2 Duo MacBooks? Is the 'whine' in the C2D louder/more noticable or does it have less of an annoying noise?
Thanks in advance
Mark

I got Core Duo - my girlfriend got Core2Duo and both have the CPU whine. There is no difference in between the two - they're not too loud but get little bit worse with time. Apparently not every MacBook has this problem - so my advice to you is go ahead and buy one - and if within 14 days you're not satisfied, have it replaced or return it for refund.
Note that the CPU whine is not really that bad - that it will keep you from fully enjoying the computer. It only bothers me when I'm in dead silent room and browse the web. However - when I use Windows XP under bootcamp - there is no whine whatsoever. So when I need to browse the web - I do it on the windows side. Besides I really like the new internet explorer
Good luck with your purchase. The macbooks are a great little notebooks. I doubt that your brother will ever complain about the CPU whine - even if it is present. My girlfriend has never noticed it.

I have a Intel Core Duo CPU (not a Core 2 Duo) - Lion OS upgrade - is there any hope?

The APP store will not let me download Lion OS ... I have an intel core duo CPU - it is saying I need a Core 2 Duo. Currently running Snow Leo. OS 2GiG RAM with plently og spack on the HDD ... is their any hope - or workaround? Appreciate any help.

SOLVED ... when submitted I noticed outer responses on the right hand side ... the Intel Core Duo CPU is 32 bit while the Core 2 Duo (and Lion X OS) is 64 bit ... I will go away now and cry ...

Will the Core 2 Duo CPU work on the Qosmio G30?

Question is as follow:
In 2 months Intel will come up with Core 2 Duo/merom cpu for laptop.
Will then todays toshiba qosmio laptop support these processors for an upgrade ?
And wonder in general how much can be upgraded with toshiba laptop's?
Like if I want to have e-sata on this laptop. Maybe not supported by chipset ?

As you know this is a user-to-user forum and I don?t think that you will find somebody from Toshiba here.
However, this is my own opinion and this could be one of the reasons. I agree with you that duo core 2 CPU supports less power and generate less heat but more or less this are also properties of the intel duo core CPUs.
But I think that in the future the duo core 2 CPU will supports a higher speed as the duo core and I think the temp will also increases.
You know that the notebooks technology is different as the desktop technology and it's more difficult to upgrade the parts on the notebook as on the desktop pc. Some CPUs are also soldered on the board. (but I'm not sure about Qosmio) But if you will be able to remove it and to upgrade the CPU so then you could get some problems with BIOS and also software (chipset utility?). Maybe this could have a bad influence on the drivers and utilities.
As you see there are more factors as only the temperature. Everything must be compatible. I think the Qosmio G30 is a very nice notebook with really good performance. I think the CPU upgrade is not necessary because you will not get much more performance as with the core duo CPU.

HT3696 I have a Core Duo 32bit system. Is there anyway to upgrade to a 64bit?

It seems I jumped on the new Intel based Minis too soon. I have upgraded all that I can...that I know at least. I have 10.6.8. An Intel, but its only Core Duo. I wanted to buy some apps, but it seems they all require 64bit!!!...at least the ones I have looked at. Is there any way that I can replace a 32bit system to a 64bit without actually buying a completely new system?!

Hi, actually you can upgradeto a Core 2 Duo CPU...

Only one core working in Core Duo X60

I bought a 2nd-hand Lenovo/IBM x60 Thinkpad about a year ago on Craigslist. Perfect condition, nice price, all legit-looking, and I'm using it now -- except that the guy had replaced the legit XP Pro with a bootleg installation of Windows7, without saving any backups or making rescue disks or anything. It worked fine and updated and everything, but I didn't want to run bootleg Windows, so I was determined to reconstruct the legit XP Pro SOMEhow. I had various Windows disks (incl. a non-legit install CD some vendor stuffed into my shopping bag) and a full set of recovery disks from my T40 Thinkpad.
It wasn't easy or quick, and didn't go smoothly, and I don't think I saved detailed notes on all the steps I took, but I finally got it running smoothly. XP Pro, SP3, with the same ID# as on the sticker, and enough updated drivers to run properly. I've been using it pretty happily for the past year, except that the speed has been disappointing. Recently, it's finally dawned on me that I'm only using one CPU core in the 2-core "Core Duo" CPU. That's presumably because the T40 only has a single-core CPU, and I used its XP setup (with some updated drivers, etc.).
Device Manager says my Computer is an "Advanced Configuration and Power Interface (ACPI) PC", not an "ACPI Multiprocessor PC".
Other than converting to Linux or buying a copy of XP Pro. . . is there a way I can educate this computer to use both of its CPU cores??
[Here's more details, and what I THINK I know about the problem:]
I think the problem is in the HAL = Hardware Abstraction Layer, and I've already tried using XPud Linux to substitute-rename the multi-core halmacpi.dll file from the SPFiles\i386 folder, making it the Hal.dll file in the System32 folder (which was formerly identical to the 1-core halacpi.dll in that folder -- no, not the halaacpi.dll file I expected to be identical). But the computer wouldn't boot Windows afterwards, so I substituted-renamed the Hal.dll file back -- successfully, without having to restore from an image. I'm guessing that there's another file or two that refer to that Hal.dll file that don't match up, but I can't find any advice online other than to re-install Windows. Since I still don't have the "real" Windows install CD for this Core Duo computer, I don't think that's a good option.
I feel a bit victimized here, because I'm going to a bunch of extra trouble to be legit, but I'm not being treated (by MS or Lenovo/IBM) as a valued customer. (I must have gotten at least 5 or 6 "You're a pirate!" error messages while I was trying to restore the computer to its original legitimate OS!)
Lenovo/IBM will sell me a new Rescue disk for $50 -- I bought one for an earlier Thinkpad, my T22, IIRC -- but I'm not confident that I'd get joy from that, either. (As I recall, the old one I bought didn't do everything I'd hoped it would do.) Plus, I'd rather not have to reconstruct and reconfigure all my software unless I have to.
BTW, I've wiped out the traditional IBM Rescue partition I had originally set up and merged it with C:. (I wanted the GBs.) I do still have an image backup of it, and I could restore it (and try using it), but there's no reason to believe that it would help, since it presumably came from my 1-core T40, not from a Core Duo machine.
Any suggestions?

Have you updated the BIOS to the latest version and checked the CPU Core setting in the BIOS?

The Whine of Intel Core Duo (mobile) (& its users) in Laptops of all brands

Can I start by saying - OH NO, NOT ANOTHER WHINE THREAD.
But I had a search and this issue doesn't seem to be covered that much yet, and I feel it's important for us blighted by the whine to work out what to do about it. Apple has told me (and a lot of you) many different answers, "We recognise this issue and we're trying to fix it", "They've all got it! Stop complaining", "It's within spec, they're MEANT to do that", "Faster processor architectures generate more noise, there's nothing we can do", "You're mad.. there's no noise."
I think we can take these points as givens:
• There are three noises commonly reported; moo (HDD-fixable) / buzz (Inverter-fixable) / whine (CPU-mysterious). We're dealing with whine here.
• Not all MBPs are created equal, some whine, some don't.
• AppleTech will feed you a line to get you to go away. Don't give up.
• A whine is NOT within spec at these prices. (check consumer rights)
• The whine is made by hardware vibration of some sort, this can be affected by software, but the software does not generate it (ie. it doesn't come out of the speakers).
• When running XP, for 99% of people the whine disappears.
• The whine seems to be related to battery power as well. Most people experience a louder whine when using (or charging) the battery.
So in a roundabout way I come to this - Does anyone know of other laptops using Intel Core Duos and causing a whine noise? In my opinion this is unlikely as the whine disappears in XP, but it would be good to know if it is happening anywhere else. If you know of any other 'whiners', please post a link to where you found out about it and the name of the model doing it.
If other models do it, it would seem to indicate defective processors (which lends credence to Apple's "it's a problem with newer, faster processors" line), and it ain't really Apple's fault - but they'll still need fixed. If Apples only do it, then we should all shout at Apple for lying to us until we get ours fixed/replaced.
My laptop is being picked up in two days to be 'repaired' so we'll see what happens then. According to AppleTech I'll get a report on any repairs done to it, so I'll post again with what repairs were carried out and what effect they had when it comes back.

Hey LanEvoVIII... (Have you ever heard one of the defective MBPs in real life? If you feel the need to reply to this post, answer that question, although it would be infinitely preferable if you just removed yourself.)
Technology is not perfect, I know that. But for the amount of money you pay for Apple technology it should be better than this. And perhaps I wouldn't have bought a computer if I'd known that it makes noises like this.. unfortunately not mentioned anywhere by Apple, only on these forums where you-who-knows-best says we shouldn't talk about it.
Also you numpty, the point of all of this is we're trying to use the return policies and hardware warranties and gettin the runaround by Apple. This is another reason why people are unhappy - not so much the problem, more the fact about it's resolution (or lack of).
So how's about this? shut yer face. I'm aware of the irony of whining about a whine. You're so smart and funny referencing the same lil joke I made at the beginning of the post. What a smart smart human you are. Go on, give yourself a wee pat on the back for being so good and understanding the nature of technology so well. Go on, do it. There, doesn't that feel nice? Now go take your smug sense of self-satisfaction to some other thread and let us try and sort this out so that it doesn't drag on any longer.
Natsus, well said, sorry but I couldn't keep such a nice calm head about it as you. I know things are better if we all stay civil to each other. After so much trouble with this issue I ain't got much patience left, especially for people like "LanEvoVIII".

Fixing a Mavericks Installation Problem
How to manage a failed OS X Mavericks installation | MacFixIt - CNET Reviews.
Try these in order:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
     after the chime press and hold down the OPTION key until the boot manager screen appears.
     Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Trying to install 10.7 on a mac mini core duo that has a core 2 duo cpu

I have installed a core 2 duo cpu (T7200) in an earlier Mac Mini core duo machine. Runs fine, the system report shows the Core 2 chip. When I try to install 10.7 over 10.6.8, however, the installer reports that it cannot install this version of OS X on this machine.
It is possible of course to install 10.7 on another machine and clone that to the hard drive here. But that seems like the hard way, jumping through too many hoops. Surely there must be somewhere in the (list of) plist files to tell the installer that it is OK to put 10.7 on this machine. I've tried a few places but w/o success. Perhaps someone is a good system hacker who knows how to do this? Many thanks,
tony

I agree-- that is a method that is often suggested. I apologize for doing the Yes, but.... routine; I have several other Macs, but I'd have to back one up (or clone it), clear the hard drive, install 10.7 on it, and then go through your suggestion. In principle it seems straightforward. I might have to resort to that. I had hoped that it would be possible for a more software-centric way, of convincing the installer that the machine was OK; Have I missed something here?
I've tried several suggested methods, and the closest so far is to get an installation from a bootable usb stick that looks like it's installing and then I get a circle with a line across it. No error messages.
the machine is a 1,1 original that now runs fine with 2 gigs memory, a core 2 duo (T7200) cpu. and 10.6.8.
I have tried removing the lines in the plist files that require the 3,1 machines, etc. but that has not helped.
If my time was worth more than 10 cents an hour I should have thrown the sucker away and bought a new one. I have an i5 Mini that screams. any more suggestions are most welcome.
thanks

Live CD x86_64 not working on Intel(R) Core(TM)2 Duo CPU

Hi,
I wanted to install the x64 version of Arch as I want to make use of the full 4GB ram my notebook has.
However, trying to boot the live cd for the x64 version allways results in a reboot after the kernel is passing on the init scripts to arch and arch is trying to load the acpi modules. Using the 686 version it works.
So am I mistaken in thinking that the Intel(R) Core(TM)2 Duo CPU supports 64 bit?

Ok, disabling ACPI in the grub kernel line seems to fix the problem. I think it's weired though, that it works with the 686 version... guess a bug report is in order.

Hi:
I am looking at the BIOS setup guide for your PC series and it shows there is a VT setting under the device configuration menu for "select models." See Chapter 3 page 6.
http://h10032.www1.hp.com/ctg/Manual/c01662442.pdf
Here are the specs on the T6500 processor. It does not support VT, which is why the VT setting cannot be enabled.

My doubt is that one of the 2 CORES might not be functioning. I am not sure since technically I am a Zero.
Any help is greatly appriciated
Thanking all

And there is no reason to remove the battery since there is that little button you can push to clear the CMOS.
you might be amazed on how many times pushing the button it's just not enough.

I doubt I would be writing you from this machine if I had flashed it with the BIOS for the wrong board
no offense but how should i know that you don't have one more comp at home.
what was the previous problem you had with the mobo for which you needed a BIOS update?
edit: just remembered something. what PSU do you have?

Can I run Lightroom on a PC with an Intel Core 2 Duo CPU?

The specs for Lightroom state that you need a Pentium 4 processor. My PC has an Intel Core 2 Duo CPU @ 2.2Ghz. Is this sufficient?
Thanks.

Hi vc10,
You can install Lightroom on Core 2 Duo Processor.
P4 processor is the minimum system requirement for it.

Swapping the Core Duo for a Core 2 CPU

I came across this web site where they describe swapping a Core Solo CPU with a Core 2 Duo CPU. My mini has a Core Duo, but with Leopard now coming out w/true 64 bit apps, and with the future being 64, I have to wonder if this isn't worth giving a try. Here's a link:
http://www.macintouch.com/specialreports/minimonster/
Knowing a little bit about hardware, I'm somewhat apprehensive. The swap they did, they did several years ago and the 64 bit migration is recent, meaning they really couldn't truly test it in that environment. Since Mini's with Core Solo and Core Duo's aren't "true 64", my concern here is really with the addressing capabilities of the hardware. If the OS is limited to 32 bits, as in earlier OS X releases, then I think it's possible that the swapping of a Core 2 in place of a Core Duo or Core Solo would work OK as long as no 64 bit addressing took place. When a newer OS comes along and tries to do 64 bit addressing, possibly the addressing hardware on the motherboard is limited to 32 bits and this would presumably fail.
I hope that's clear. My mini is a late 2006 model FWIW, and at the time the only processors being offered with it were the Core Duo's.
Thanks.

I have a similar question.
I have a 2006 xeon macpro.
Will i beable to upgrade to lion.
I saw this on the website today.
Step 1:Make sure your Mac can run Lion.
Your Mac must have an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor to run Lion. Find out if your current Mac has one of these processors by clicking the Apple icon at the top left of your screen, then choosing About This Mac.
Here is what i have.
Processor Name: Dual-Core Intel Xeon
Processor Speed: 2.66 GHz
Will i be good to upgrade?
Thanks

Intel(R) Core(TM)2 Duo CPU Freeze Issues

Hi,
I have dual boot option windows 7 OS and windows server 2003 installed and have been facing two issues:
1. No drivers available for windows 2003 Enterprise edition. I have already written to MSI support for this and the answer was that I need to hunt specifically for the drivers from chipset vendors. If any of you have the drivers for windows 2003 and windows 2008, please share the same.
2. I had previously multiple combinations -windows XP and windows Vista, windows XP and windows 7, windows 7 and windows 2000/windows 2003. In all these combinations, I have always faced a problem of system freezing and not doing anything at all. Mouse and all system activities comes to a still. Unable to find out what the issue is about. Please let me know the issue resolution ASAP. I am putting some details regarding the system below (as taken from system information from windows 7), please let me know if you want complete system information and how to upload it.

And which drivers in particular do you need? Best I'm aware is that Windows XP drivers are usually suitable for use with Windows Server 2003. And for Windows Server 2008, Vista/W7 drivers should work.

Well this particular 'issue' could be caused by just about anything, so without knowing more details about the hardware in your system, as well as more information on the problem you're having, there is no magical quick-fix solution we can give.

Can u put a core 2 duo cpu in a core duo MBP?

as above

I suppose you could if you're up to de-soldering 478 very small pins to remove the old Core Duo, cleaning the contacts, and resoldering the pins of the Core 2 Duo to your logic board.
