Core Duo memory limit?

As far as I'm aware, my MBP Core Duo has a limit of 2GB. It has 1GB pre-installed, so is the most I can buy 1GB extra? If this is true, how come on the apple website, I gives me the option to buy a 2GB stick, which would mean I'd have 3GB... And the 2GB stick they offer is 2X1, but I'm pretty sure there is only 1 free expansion slot, so I'd have 3 sticks of memory - the 1 pre-installed and the 2 I'd buy... I feel like I'm in grade school, but I'm a little confused. Can someone please explain what I should do. Thanks.

The Core Duo models only support 2 GBs. There is no option to purchase a 2 GB module for a Core Duo - only for Core 2 Duos. The 2 GB set consists of two 1 GB modules that replace the two 512 MB modules that were originally installed in the Core Duos.

Imac 20'' Core Duo memory specs

Hey,
im thinking to expand my imac's total 1gb ram
and im really confused from what i've read about the memory amount a ram module
should have.(some say it can be expanded to 4gb(3gb used))
I know for a fact that it can be expanded to a sum of 2gb (2x1gb).
Is there a way to find out?
I bought my imac on 06/2006 but i cant be sure which imac is(early or mid 2006) as im not living in the states or in any other technologically "advanced" country.Forgot to mention that the model is imac 20'' intel core duo
cheers.

Adding Memory to a White MacBook 2.16 Ghz Intel Core Duo (Memory 1Gb 667 Mhz DDR2 SDRAM)

Good afternoon from London.
I want to put 2x2GB memory into my MacBook (mid 2007) but Apple support site specifies that the maximum amount of memory for this model is 2Gb. In other words, I can only add 2X1Gb.
What would happen if I proceed?

Thanks. They say the following, which I take to mean that I am good to go:
MacBook2,1 (All) - Install up to 4.0GB total memory, uses up to 3.0GB.
Note: Although limited to physically utilizing a maximum of 3GB, there is a performance
benefit due to 128 Bit addressing when 4GB( 2GB x 2 Matched set) is installed.

I have a old 2006 modle macbook 15 inch the A1150 i believe with core duo processor can change or replace that with a intel core duo 2 processor ?

it,s a 2.16 GHz Intel Core Duo
memory 2 GB 533 MHz DDR2 SDRAM
is there some kind of way i can upgrade that to a Intel Core Duo 2 processor
or is it just a batle i cant win ?

You should be able to get a used or repaired MacBook 13/15-inch core2duo 2.0+GHz near
$350 or so, in working condition with some kind of limited warranty or guaranty. Companies
like macsales, wegenermedia, powerbookmedic, powermax and others offer previously
owned Macs that are not current models. Older, to vintage or obsolete; those who some-
times have the better deal on those also can repair most all Macs and have parts.
The effort to swap out a logic board (and then what? the
other parts likely won't match) isn't hardly worth the effort.
You may be able to find an early MacBook (circa 2006 to 2010 era) that needs minor work,
and troubleshoot/repair it with a DIY guide online... But that can be a gamble if you mess
up things that were not wrong in the first place, while learning on the job. It could cost plenty.
Some companies can sell you used parts, no guarantees on matching an incorrect logic
board with a diffferent build model spec computer's other original configuration. You'd do
better if you found someone selling their old MacBook Core2Duo, nearby, & could see it run.
I have a MacBook 13-inch coreduo 1.83GHz first-edition; an early core2duo won't do much
more than the coreduo. Snow Leopard is better than Lion in several ways; if you have older
software you already own that works, from the PowerPC era -- that can save you money.
Good luck in any event, & happy computing!

I'M MAD! Majority of games/apps require 2 GHz Intel Core Duo...D:

So to start off, I have a Mac OS X 10.6.8
     Processor 1.83 GHz Intel Core Duo
         Memory     2 GB 667 MHz DDR2 SDRAM
What I want:
     To be able to play games/apps
"Why can't you?"
     Because they require 2 GHz Intel Core Duo
So my question is:
     IS THERE A WAY I CAN UPGRADE TO A 2 GHz INTEL CORE DUO???
     ...it makes me frustrated that I have the required OS version yet I still can't play games or use simple apps because of my stupid processor...
What I've already tried (so don't suggest this):
Wine (so that I can open windows required games)
Updating all my software
Getting rid of unwanted files
Downloading X11 (to run Wine)
Watched tons of tutorials on downloading desired games/apps correctly
EVEN BUYING A NEW COMPUTER (this one)
Repeating the above tactics on my new computer
     What. must. I. Do. Please tell me !!

Have MacBook Pro (ancient) has 2.16 Ghz Intel Core Duo with 1 GB 667 MHz RAM using OS 10.4.11. Can I upgrade OS? If so, how far? And can I add more memory? I realize this is an old laptop but I need to wait to upgrade to new.

Please describe the problem in as much relevant detail as possible. The "etrecheck" fad hasn't made that step any less necessary. The usual results of posting etrecheck output on this site without a full description of the problem are very poor.
The many "failed" warnings that etrecheck sometimes spews mean nothing. Those warnings are not a reason to reinstall the OS, or to do anything else at all. They should be ignored.
The better your description of the problem, the better the chance of a solution.
For example, if the computer is slow, which specific actions are slow? Is it slow all the time, or only sometimes? What changes did you make, if any, just before it became slow? Have you seen any alerts or error messages? Have you done anything to try to fix it? Most importantly, do you have a current backup of all data? If the answer to the last question is "no," back up now. Ask if you need guidance. Do nothing else until you have a backup.

Sounds to me like you may have gotten a machine with hardware issues, but it's hard to say. It will shut down if it gets too hot, but that's not a normal occurrence. I have never seen a MacBook Pro shut down due to heat, even after lengthy 3D gaming sessions where the fans are running fast and the bottom of the machine is unpleasant to touch.
First thing I would try to do is reset the SMC. If that doesn't help, erase the hard drive and reinstall the system from scratch, which you should always do with a used machine anyway.
If a fresh system doesn't help, you'll need to get it checked out by Apple.
Edit: Oh, and sig is absolutely right... please don't post in all caps! It's very irritating.

First, back up all data immediately, as your boot drive may be failing.
Launch the usual set of applications you use when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. What approximate values are shown for Reads in/sec and Writes out/sec?
Step 2
You must be logged in as an administrator to carry out this step.
Launch the Console application in the same way as above. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Post the 50 or so most recent messages in the log — the text, please, not a screenshot.
Important: Some personal information, such as your name, may appear in the log. Edit it out before posting.

Open the Mac App Store and try downloading Yosemite. If you get told it's incompatible, choose About this Mac from the Apple menu, check if the computer has at least a Xeon or Core 2 Duo(not Core Duo) CPU and 2GB of RAM, and if it does, click here and order a download code for Lion 10.7.
Back up your data and check your applications for compatibility before upgrading. In particular, Mac OS X 10.7 and newer don't support PowerPC programs such as versions of Microsoft Office prior to 2008.

21.5" 2.4 ghz Intel core duo with 4 GB memory iMac w/ OS X 10.5.8

my 2008 21.5" 2.4 ghz Intel core duo with 4 GB memory iMac is running OS X 10.5.8 and has recently started over heating and locking up .... even with applications that it has never had problems with before .... I don't think it's capable of being upgraded any further, right? can I upgrade the graphics card or is that even worth it?

Your tems are fine, nothing at all to worry about. One thing you can do is shut down the computer, remove the RAM plate cover on the bottom and vacuum out the air intake. As for the spinning beach balls that isn't a freeze it means a process is busy. You can run Activity Monitor (Applications - Utilities - Activity Monitor) and when you begin getting SBBOD look in AM and see if you see any processes using a large %CPU and also click the System Memory tab and look to see how much FREE RAM is available at that point in time. As a general rule of thumb OS X likes to have 500MB or more of FREE RAM, if you see it's at or below 500MB then a RAM upgrade is needed or you need to reduce the amount of open windows. The graphic will look similar to:
Also I'd strongly recommend carefully reading the XLab's Spinning Beach Ball of Death article. It's an excellent guide on how to trouble shoot spinning beach ball issues.

Ram limit in macbook pro core duo

hi
I was wondering what the limit of the macbook pro core duo is. I know it says 2 gb but has anyone tried a 2gb chip + 1gb chip? I also know the core2's can do 3gigs.
I have had laptops that thave worked with way more than the specs said. My pismo's limit according to apple was 512mb ram I have had 1GB in that for many years. I think the 512 mb chip was the larges one at the time the computer was released so thats what was reported. is it the same thing with the first generation macbook pro's?
thanks
t

According to Apple's specs the limit for the MBP CoreDuo is 2 GBs. The limit of the Core2Duo is 4 GBs although only 3 GBs is user accessible.
The spec limit for the Pismo is 1 GB (512 MB per slot.) When new models are released sometimes there isn't RAM available to suit the limit of the model, so Apple can only certify a max based on what's currently available. You will find this is true of many older Mac models such as the Pismo.

While we all have MacBooks in this forum most of us don’t run Lion. There's a Lion Support Community where everybody has Lion. You should also post this question there to increase your chances of getting an answer. https://discussions.apple.com/community/mac_os/mac_os_x_v10.7_lion

I am running 10.6.8 but can't upgrade to Lion. 1.83 GHz Intel Core Duo processor 1.83 GB memory. What should I do?

My MacBook software is 10.6.8 but I can't upgrade to Lion. 1.83 GHz Intel Core Duo with 2GB memory. What to do?

Lion/101.7 System requirements
    •    x86-64 processor (Macs with an Intel Core 2 Duo, Intel Core i3, Intel Core i5, Intel Core i7, or Xeon processor.)
    •    At least 2GB of memory, (I say 4GB)
    •    Latest version of Mac OS X Snow Leopard (10.6.8), with the Mac App Store installed
    •    At least 4GB of disk space for downloading, (I say 40GB at least)
Like Snow Leopard, Lion does not support PowerPC-based Macs (e.g., Power Macs, PowerBooks, iBooks, iMacs (G3-G5), eMacs).
Lion also does not support 32-bit Intel Core Duo or Core Solo based Macs. Rosetta is no longer available in Lion, which means Lion no longer supports PowerPC applications.

Will increasing the memory from 4Gb to 8Gb make a big difference to the speed of my Intel Core Duo 2 Mac mini?

Will increasing the memory from 4Gb to 8Gb make a big difference to the speed of my Intel Core Duo 2 Mac mini?

Well, technically no, CPU will remain the same speed. But having 8 gig will give you some room for memory hungry apps and run better with multiple apps.
Adding a SSD drive will give a second life to your macmini. I did mine a few weeks ago (240 gb SSD ) and also went from 2 to 4 gig ram. It's like having a new computer!
Good luck!
