Core Duo and Core 2 Duo

So, my black 2 ghz Core Duo is in need of a new hard drive. Of which I'm waiting for a warranty replacement.
My wife's white 2.16 Core 2 Duo macbok will be mine for the next week. Will my RAM from the black macbook work in the white macbook? Are they interchangable?
TIA!

All white and black MacBooks come from the factory with PC2-5300 (DDR2 667) memory - more than likely CL=5. They should be interchangeable, but there is the caveat about total memory supported in various versions of the MacBook.
I'm not sure why you'd want to do this unless somehow your Core Duo has more memory than the Core 2 Duo machine. The standard build for the Core Duo MacBooks was 2x256MB, while the standard build for the Core 2 Duo 2.16 was 2x512MB.

Java Development issue/differences between Core Duo and Core 2 Duo (??)

Hi Everyone,
I am a Java developer that uses my 17" MBP Core Duo for all of my development. Lately, I've been trying to use both the Glassfish Application Server V2 (from Sun) and Maven 2.09 from the Apache project. I have configured identical scenarios on my MBP Core Duo and on a 15" MBP Core 2 Duo.
The scenario involves compiling and running some webservices (at least on the Core 2 Duo) in a local development environment. Both machines use the default JDK 1.5.0_13 installed on the machine.
On the 17" Core Duo, issuing a "mvn install" command produces the following error:

I have installed the same software versions and have the same configuration on a Windows desktop running XP SP2 and get the same successful result.
Is this an issue between the Core Duo and Core 2 Duo? I can't see that it is since I don't believe the hardware influences the software to that degree. However, I am at a loss for what is causing the issue and the Apache Maven list insists that there are developers that are using Maven successfully on OS X.
I really need to get past this issue, but I am at a loss. Please help.
Thanks,

LabVIEW Core 1 and Core 2 training effectiveness

I'm scheduled to take LabVIEW core 1 and core 2 training in the second week of October. I would like to get an idea on how effective this training is, and how to approach it.
I work in a test and measurement lab and we use LabVIEW to automate our testing (RF, EMI/EMC). We currently have some labVIEW programs up but no one to maintain/upgrade or design new processes and I am planning to step into this role. Is it feasible to expect to jump right in after the training?
Thank you.

Core I and Core II will teach you the fundamentals of what LabVIEW does. (And some very valuable skills)
It will not teach you how to architect a robust framework for test. That's something you will need to learn to step into a Lead Developer role.
It will not "Give" you a source code control repository. That's something your boss will need to provide to keep your work product safe.
It will not provide mastery of best methods and practices with a thourough knowledge of the intracacies of programming in LabVIEW for yor companies needs. BUT, you found the forums.....come back often! You'll learn more here by accident than you might imagine!
I found Core 1 and 2 to be very nice affirmations of what I have learned here!
I would highly recommend taking this tutorial in advance, so it won't be totally alien to you when you start the training. It's better to start out with some questions and some answers, than no questions or answers.
Post-training, I would recommend Bloomy's LabVIEW Style Book. You don't have to get the latest, greatest edition - most of the guidance there is timeless.
[edit]
LOL it would appear that I am responding the wrong post. I assume Jeff has advanced LabVIEW knowledge.

Core-1 and Core-2 study materials question

first let me start by apologizing if i am posting this in the wrong section, I'm pretty new here. I am enrolled to take the labview core-1 and core-2 classes at a training center in Ft Wayne Indiana in February. I am having surgery tomorrow on my foot so I will be off of work and laid up for a few weeks, so I was wondering if there were any good study materials i could start using to help gain some knowledge before attending the classes. I play with labview a bit, but not knowing much I'm limited on what i understand while "playing" with it. i have found this forum to be great for finding information, but not having any official training most of the stuff i find in the forums is still over my head. i do intend on continuing my education in labview and going for the CLAD certification when i get to that point and feel ready to take the exam. can anyone help guide me in a good direction to start gaining knowledge that will help me along in my journey in learning this amazing world of labview? thanks in advance for any help you can offer. again, i apologize if I am posting this in the wrong section.

Core2 Duo and Core Duo?

I'm finally converting to mac and want to buy a mac mini but I was wondering if someone could help me out first. Is there a difference between the Core 2 Duo and the Core Duo? I was wondering if it would be better to wait for the Mini's to come out with the Core 2 Duo first before I bought one. I'd say if there's not much of a difference, I'm going for it. Any suggestions would be greatly appreciated. Thanks.

but apple used to put a video car in the mini and the
ibook's. there starting to get cheap. i kno the cards
wernt top of the line but it made it a mac and not a
junky peecee
There are many points to make:
1 - A Mac is not defined by the hardware but by how the system works, what it does, and how it does it. I would point out to you that the vast majority of users would find it hard to discern their system was Intel or PPC, or had a video card or integrated graphics. Some know and care, but most don't.
2 - If you think integrated graphics equates to a 'junky pc' then it's time you tried a mini in comparison to an equivalent Dell.
3 - You can ignore the technical issues if you want, but enhancements in systems design and chip performance have given rise to much better integrated graphics sub-systems than ever existed before.
4 - There are many people who would consider the ATI 9200 (for example), as used on the G4 minis and many iBooks as extremely poor and limiting. Not surprising since by the standards of the day it was used on those systems it most assuredly was. It was also significantly inferior to the integrated graphics systems on the new models.
5 - Horses for courses. Low-end systems will have low-end specifications both to hold prices down and make the entry-level models accessible to the buying public, and to ensure those models don't cannibalize sales of the higher-end gear. It would be idiocy of the worst sort to risk bumping the entry-price for Mac ownership up at all in order to include a video card that most users have no reason to actually want.
6 - Prejudice against a design element doesn't equate to good technical evaluation. Objection to the integrated graphics choice is understandable in the historic context, but needs to be evaluated against the backdrop of what users actually want and realistically from their systems.
7 - If anyone were to have specific need for a dedicated graphics sub-system in their Mac, there are plenty of models to offer it.

Difference between core duo and core 2 duo

I want to upgrade to Leopard starting where ever i need to but I cant figure out how o do it. On some of the discussions it says must have core 2 duo more, my macbook says core duo. Is this the same thing or different? Any advise on how to upgrade would be appreciated. I want to upgrade itunes and cant because i get the message not compatible wit this version of OS X.. Please help

1. As stated above, you need to purchase Snow Leopard on DVD. Don't worry about any intermediate versions.
2. The newest version of iTunes which will run on 10.4.11 is 9.2.1. If you need to upgrade because you purchased a new iPod or similar device, you'll almost certainly need to upgrade your OS too.

Please verify core duo vs. core 2 duo speed comparison

Hi,
I was looking for RAM to upgrade my MacBook CoreDuo 512mb to 2gb, and found this:
http://eshop.macsales.com/Reviews/MacBook/Testing/Memory_Benchmarks
If you go down, there is performance comparisons b/t core duo and core 2 duo, and between different size of rams. I am looking at photoshop result. Notice C2D 1gb is FASTER than CD 2gb.
Since I will be using Photo Editing Apps. to process RAW files, speed is my primary concern. Could you please verify this data? If this is true, I am going to consider selling my current MB and getting a new one with C2D.
Thanks!

Performance comparisons vary from tests to tests. And even if you test the same machine 10 times, you will get 10 different results. But from looking at the data, it seems though that the differences are very minute.
Selling your CD MB to get a C2D MB would not be a smart investment for that small improvement in performance, but the decision is up to you. If you decide to upgrade since speed is your primary concern, why not opt for Macbook Pro?

2.33 intel core duo and G5 2.0 dual desk

Hi i am using a g5 2.0 dual processer with 3.5. ram with lots of synths may b all possible softwares including viena..
i want to buy a laptop 2.33 macbook intel core 2 duo and work on the laptop with the same logic setion with all the synths at some other place..
what i want to know is can the laptop open the smae amount of plugins and the synts which i open in my desktop G5 2.O DUAL..or may be more..let me tell u that my setions are preety heavy because i do also compose filmscore and do program the fulll 20 min. reel in 1 setion.i have my own studio n i also have a quad 2.5.the idea to buy the laptop is to carry the same setion outdoor and work n get it back..
please help me with this.else i will loose my money buying a laptop.and not get the same result.
your suggestion should be helpful for me..

hi,
I have exactly the same G5 as you (but with more RAM) and I also have the MBP 17" C2D 2.33 GHz.
as far as I can tell, my MBP is more powerful running logic than my G5 is. I don't think you'll have any trouble getting your work done on the MBP you are looking at. in fact, you might even find that if a project you are working on gets close to pushing the MBP to its limits, it won't even play without freezing tracks on your G5.
the only thing to keep in mind is that you have more limited i/o options on the laptop.. meaning that if you are expecting to use an audio interface with many inputs and outputs working simultaneously, as well as a fast external firewire drive, then you'll be pushing the boundaries of your firewire bus to get enough bandwidth. whereas on the desktop machine, your extra drive space can be internal drives that have their own SATA bus, and your audio i/o can be either FW or PCI. but if you're just composing and producing music on the machine, without trying to record 26 simultaneous audio tracks and streaming vienna orchestra sounds off of a firewire drive all at once, then you won't have any trouble.

Question: I want to update to the new LION OSX, but it says that I need to at least have an Intel Core 2 Duo. When I click "about this Mac," it says that I have a 2.16 Intel Core Duo. Is there a difference between the "Core 2 Duo" and the "Core Duo"?

Well, my title basically asks the question that I am seeking an answer for. Im not sure what year my MB Pro is, and I cant exactly find it on the Apple site. Its a 2.16 Intel Core Duo, 2 GB 667 MHz DDR2 SDRAM. All I see (dating back to 2007,) is Intel Core 2 Duo on the apple site. Im pretty sure (but not 100% positive,) that my MB Pro is a late 2008/early 2009. Just trying to figure out if I can install LION OSX or not, since it requires atleast intel core 2 duo, and mine says I only have the intel core duo. Any help would be appreciated. Thanks!

HT201364 I'm currently running OS-10.6.8 on my IMAC with an Intel Core 2 duo and would like to update to at lease 10.7

I'm currently running OS-10.6.8 on my IMAC with an Intel Core 2 duo and would like to update to at lease 10.7. Can this be done and if so how?

Only if you cannot upgrade to Mavericks.
Upgrading from Snow Leopard to Lion or Mavericks
To upgrade to Mavericks you must have Snow Leopard 10.6.8, Lion, or Mountain Lion installed. Purchase and download Mavericks (Free) from the App Store. Sign in using your Apple ID. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mavericks- System Requirements
       Macs that can be upgraded to OS X Mavericks
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
         See App Compatibility Table — RoaringApps.
Upgrading to Lion
If your computer does not meet the requirements to install Mavericks, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.

I have a MacBook Pro with Intel Core Duo and Snow Leopard 10.6.8. Want to upgrade to Lion to take advantage of icloud. Is there anything I can do without getting a new MacPro?

I have a MacBook Pro with Intel Core Duo and Snow Leopard 10.6.8. Would like to upgrade to Lion but it requires a minimum of Intel Core 2 Duo. Can I get what I need or do I have to buy new MacBok Pro?

I also have a core duo MBP with Snow Leopard and it runs perfectly. There are very few things it cannot do as compared to the faster, newer MBPs, but that is attributable to the CPU, not the OS. There are some who view Lion as downgrade rather than as an improvement. If there are important applications that reqire a fast CPU or Lion features that you find essential, by all means get a new MBP.
I have an aphorism: Obsolescence is more often a perception rather than a reality. Besides the silver keys look much classier than the black ones.
Ciao.

Difference between Intel Core Duo and Intel Core 2 Duo

I bought my MBP in November of last year, before the update on the Pros. However, it says about the new Pros that they have Intel Core 2 Duo processors, which are faster than the Intel Core Duos of previous MBPs. I know I bought mine before they updated them, but my "About This Mac" says that mine has an Intel Core 2 Duo processor. So, did they update the processors before this latest update, or do have one of the new Macbooks somehow, or what happened? And, is there any difference between my 2.4 GHz Intel Core 2 Duo, and a 2.4 GHz Intel Core Duo?

Only the original Intel machines came with Core Duo processors. The principal difference is that Core Duos are 32-bit and Core 2 Duos are 64-bit processors. There were also increases in available clock speed, L2 cache, and frontside bus speed. The first models only addressed 2 GBs of RAM. Later models had a different memory controller that enabled 3 GBs of user accessible RAM (4 GBs installed) and even later models such as yours had a memory controller that enabled accessing 4 GBs of RAM (4 GBs installed.)
The first Intel Minis came with a Core Solo processor which had only one core instead of two.

I have an 20 inch Imac 2,4 GHz Intel Core 2 Duo and I want to introduce Final Cut Pro X into the machine, can I change the Vieodcard ATI Radeon HD 2600 Pro 256 MB, into a more suitable videocard? Or is that not possible?

I have an 20 inch Imac 2,4 GHz Intel Core 2 Duo and I want to introduce Final Cut Pro X into the machine. Can I change the present Videocard ATI Radeon HD 2600 Pro 256 MB, into a more suitable videocard? Or is that not possible? I have upgraded the memory to 4 GB 667 MHz DDR2 SDRAM.

The GPU in a iMac is NOT upgradeable.
You should check to see if your model of iMac meets the minimum specs to run FCPX.
I believe that your GPU is NOT OpenCL capable, and hence not supported.
Even if it works, you would probably get marginal performance.
What you can do is download the trial version and see how (and if) it works.
