IMac 8,1 2.66Ghz Core 2 Duo maximum ram upgrade possible

I have an iMac 8,1 2.66 Ghz Core Duo, right now I have 2Gb Ram, and I am going to upgrade it. Some forums suggest that it is possible to install a 2GB and a 4GB slot to get 6Gb, and some others says it is better leave it up to 4Gb. Can someone tell me if I should go for 6 or 4GB, I obviously prefere going for 6. Thanks

6 GBs is the max.
Correct and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (macsales.com).
Here's the 6 GB RAM kit from OWC (macsales.com)

What is the maximum ram upgrade possible on a Mid 2011 iMac 21.5-inch

I have an iMac 21.5-inch, Mid 2011 running OS X 10.9.5 which currently has 4 GB 1333 MHz DDR3 Ram. The Hard Drive has 149.87 GB free out of 499.25 GB. It has been running slow for a while now. I would like to know what is the "TRUE" maximum Ram Upgrade possible. The reason I say "TRUE" is because the specs say one things when I find others saying another. I would like to install the maximum Ram that will increase the speed to its optimum. I have read some information that this particular computer will not take advantage of anything past a certain amount of ram.
So with all that said, I am asking for specific numbers, types of ram, suggestions etc etc...
Thanks

Here's what you can do and need:
Maximum Memory
32 GB (Actual) 16 GB (Apple)
Memory Slots
4 - 204-pin PC3-10600 (1333 MHz) DDR3 SO-DIMM
Sources for memory I recommend are:
OWC

2.16 GHz Intel Core Duo/ 2GB ram upgrade ?

Please could someone tell me if I can upgrade my MacBook Pro 2.16 GHz Intel Core Duo/ 2 GB SDRAM running 10.6.8 to Lion as I need it to run some 2015 software ?
IF I can, what are the dangers I must look for and will my laptop then be even slower than it is now?
Thank you very much,

I apologise for my ignorance and thank you again.
You have no reason to apologize. We all have to start from the beginning in every endeavor.
I too am very happy with my 2006 MBP however with the introduction of HDTV, the 2006 MBP was not up to the task. That resulted in the purchase of the 2010 17" MBP because I needed that capability. Technological change does often require newer and better equipment. As I have alluded to, I still use the 2006 with great pleasure.
I have also purchased a late 2011 17" MBP which I feel is a slightly better machine than the 2010. The 2011 has SATA3 internal interface whereas the 2010 has SATA2. What this means is that the 2011 MBP can utilize the full potential of current SSDs whereas the 2010 cannot. Do not misunderstand, an SSD in a 2010 will still be a significant performance enhancement. Also a 2011 MBP will accept up to 16GB RAM (also at 1600 MHz) whereas the 2010 can only utilize 8GB RAM (the 2010 13' model being an exception). The 2011 MBPs also have slightly better GPUs than the 2010.
On the plus side for the 2010 MBP, it is more energy efficient than the 2011. In other words, longer battery run time.
The 2011 MBP has a quadcore CPU which is not the great advance that some may lead you to believe. It shines only when a given application can utilize the parallel processing that it affords. Though not as critical, do opt for the fastest CPU available if there is a choice.
I like the 17" displays in the newer MBPs (late 2008 and newer) due to the 1980 x 1200 resolution. That is compatible with HDTV. The retina display are nice, but not nice enough to warrant my purchase of a 15" model.
Both my 2010 and late 2011 MBPs will run any applications that a newer MBP will, but perhaps not quite as fast. Neither is obsolete, yet.
Ciao.

Maximum RAM upgrade possible on a mid 2011 iMac 27"

Can I upgrade my mid 2011 Imac 27" to 32 gb of RAM. Apple handbook says only possible to upgrade to 16gm (4x 4gb cards). Has anyone upgraded a 2011 Imac 27" to 32gb of RAM?

Yes, both OWC, http://www.macsales.com and Crucial, http://www.crucial.com offer 32 GB ram kits that are guaranteed to work...to do that you would be best to not buy from sources that are not Mac specialists and who guarantee their ram to work.

If you want to sync it to the iPad from that Mac, you need to upgrade it to at least 10.5.8.
If you want to copy the music to another Mac, you don't. Move the iTunes folder of the item in the Finder's sidebar over as you would any other folder. If you put it somewhere other than the Music folder, launch iTunes with the Option key held down and point it to that location.

My Imac 2.0 GHz Intel Core Duo keeps powering off

Hi all,
I have a 20inch 2.0 GHz Intel Core Duo (Imac 4.1), Over the last few weeks the Mac would just power off on the odd occasion when using Apeture, I put this down to being the just overworked for processing picture. This seems to have been getting worse and kept occurring more and more often. Light Internet browsing was fine..
I decided after some time to replace the 2gb memory i had to see if that would fix the issue, this seemed to work for a few days then the same issues returned.
I now seeing this issue occured just by opening Safari and decided to rebuild the Imac, I completed the Snowleopard install and all seemed ok for a day then it re-occurred again and seemed to be worse, I then removed the 2gb memory and just kept with the 512mb as when bought... Still it keeps powering off. I have moved to different power sockets and still see the same issues.
Please note in order to power the Imac backup up I have to leave the power out for about 20-30 minutes, If i leave the power plugged in it never boots backup up.
I now decided to even revert back to Lion OS, but it just powers off during the install...
I thinking it sounds like a Power supply issue but would like confirmation before I take it to a repair shop..
cheers
Dan.

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

Bluetooth Error on early 1.66Ghz Core Duo Mac Mini model.

Something really weird that wasn't really happening until a couple weeks ago... I can connect to a bluetooth enabled cell phone just fine... I can even transfer some small files back and forth okay, BUT... if I attempt to transfer something big, like a music file... a 3MB mp3 per say... it will start the transfer and after a few seconds, sometimes longer... the error comes "The Hardware bluetooth is no longer available" ...
NO CLUE!!!
Anybody around having the same problem or had maybe?
Thanks a lot and PEACE!

Mac Mini 1.66Ghz Code Duo, 160Gb SATA, 2Gb SODDIM Mac OS X (10.4.8)

If this mini was bought new in May 2007 it is still under warranty, and you should contact Apple. If you have an Apple store in your area you can make an appointment at the Genius Bar and have it looked at. If not, then simply call Apple and describe the symptoms. If they can't walk you through a series of troubleshooting steps to identify and resolve the problem, they'll arrange for the system to be returned to them for service. You don't have to put up with a defective drive.
On a broader note, it's not likely to be your media, as long as you are trying to use good quality blanks rather than a low-cost generic brand. You might try a good quality blank from a different manufacturer to check however.
Also, you mention 'Disco' and 'Toast' - which implies you have installed alternative CD buring software on the system. Nothing wrong with that, but make sure these applications are properly compatible with your version of MacOS, and the system - particularly that they are Intel-native copies. A problem with third-party burning applications could cause the symptoms you describe.

Mac Mini Core Duo 2 RAM Addressing

I would like to upgrade my Mini Core Duo 2 667 MHz RAM to the maximum level of 4 gigs. It was purchased new from Apple in the spring of 2009. I have read on YouTube that this particular model cannot address the full 4 Gigs of installed RAM, instead it can only address either 2 or 3 gigs of RAM even though 4 gigs are installed. I have also heard that if 4 gigs are installed the "About This Mac" window will say that only 3 gigs are installed, but that the computer will actually use the full 4. Can someone please clear up this confusion?

Welcome to  Discussions!
If your mini is showing a 667 MHz bus for the RAM, it's a pre-'early 2009' model. Your limit will be 3gb of RAM, even if you install 4gb (2x2gb sticks). About This Mac will show the 4gb installed, but you will only be able to use 3gb. You are best off running a 2+1gb configuration and saving some money. The 'early 2009' mini has a 1066 MHz bus and can actually support 8gb unofficially with an upgrade to the EFI Firmware.

I have a MacBook Pro 3.1 2.4ghz core duo 2gb ram

Hi i am currently running ios10.8.5 mountain lion perfectly fine with no issues at all some people said i would not be able to run ml on this macbookpro without upgrading the ram etc just wandered if it runs mountain lion ok will it run mavericks ok.

You can run OS X Mountain Lion with 2 GB of RAM, but you cannot be sure that it will work correctly.
"MacBookPro3,1" belongs to the Late 2007 MacBook Pro, so it is compatible with OS X Mountain Lion. However, you say your MacBook Pro has got an Intel Core Duo processor, when it should have got an Intel Core 2 Duo processor. You can check which processor you have in  > About this Mac.
I recommend you to upgrade RAM. You can buy more RAM at OWC or Crucial.
The latest OS X version is Mavericks and it is free, so you may want to install it instead of OS X Mountain Lion. You can download it from the Mac App Store. If you want OS X Mountain Lion, you can buy it in the Apple Online Store > http://store.apple.com/us/product/D6377Z/A/os-x-mountain-lion
