If you or your Mac really needs the 6GB RAM than sure.
The slight decrease in speed due to not using paired-RAM isn't comparable to the gain you get from the additional RAM.
Have you used Activity Monitor as described in here Mac OS X: Reading system memory usage in Activity Monitor to determine whether you need more RAM ?

10.10 painfully slow on 2008 iMac 2.4gHz intel core 2 duo

I made a big mistake-
My gf sees me as the guy who really knows Macs.
I updated her 20" iMac 2.4gHz intel core 2 duo (3G ram) when the prompt came up in software updates.
Now she's practicing patience as everything is much slower and problematic in keeping connected to the ISP.
Accepting that the Mac has to re-index everything, we've allowed 3 days for this, but not much improvement.
The question:
What is Best Practices (and detailed method) for getting back to her previous OS without the install disk?
This is probably best until we can get a new Mac on her desk.
Is it better to stay with 10.10.1 - if so, we need to speed this puppy up.
Any help?

The first problem may arise from the fact that iMacs use 3.5" harddisk whereas most SSDs are 2.5" ones.
So some sort of tray or 'holder' is needed.
Second problem might be the thermal sensor Apple uses in some iMacs.
Your first recommendation to your friend: 'get a bigger harddisk and more RAM' sounds like the best way.

Is RAM and OS for iMac 2.16GHz Intel Core 2 Duo upgradeable?

Can the RAM and OS for a iMac 2.16GHz Intel Core 2 Duo with 1GB RAM, 667 MHz DDR2 SDRAM, MAC OS X 10.6.8 be upgraded? Looking to upgrade to 4 GB RAM and OS X 10.8. Please advise. Thanks.

Welcome to Apple Support Communities
Of course you can upgrade RAM. You have a Late 2006 iMac, which supports 4 GB of RAM. You can buy more memory at OWC or Crucial > http://eshop.macsales.com/shop/apple/memory/iMac/Intel_Core_2_Duo_2006
This Mac can't be upgraded to OS X Mountain Lion because OS X Mountain Lion needs a Mid 2007 or newer iMac. Instead, you can upgrade to OS X Lion by calling Apple > http://support.apple.com/kb/HE57 Make a backup of your files with Time Machine and check that your applications are compatible > http://www.roaringapps.com

I recently updated the original ram from my 2.66 Ghz Intel Core i7 15" laptop. Can I take that ram (4GB set) and put in my iMac 2.4GHz Intel Core 2 Duo?

The 15" power book had this:
Memory Type: DDR3 PC3-8500, DDR3 (non-ECC)
The 20" iMac has this:
Memory Type: DDR2 PC2-5300, DDR2 (non-ECC)
I'm not sure what the difference between DDR3 and DDR2 is. Any support would be great.

DDR stands for Double Data Rate, the original DDR had a speed of 266MHz, double the rate of the previous memory standard of SDRAM which ran at 133MHz. DDR2 and then DDR3 are the successors of DDR. To avoid fitting the wrong type of module they use different memory slots and will only fit the one they were designed for, by way of slots cut in the memory boards at precise positions which correspond to notches in the memory slots.
If you want to know what memory will fit which computer I would go to the Crucial website and use their online Memory Advisor, put in the brand and model, it will tell you exactly which modules fit it and what kits (if any) Crucial have available for it.

Your Mac is definitely one of the supported models? http://www.apple.com/uk/osx/specs/
If so, what happens when you try to download? Is it a case of nothing happens? If so, take a look at the suggestions under 'Stalled Download' in this link:
http://www.wired.com/gadgetlab/2013/10/mavericks-issues-and-fixes/#slideid-23477 1
Also, some usrs have found that logging out of the Mac App Store and then back in again and starting over has kick-started the download. It seems that the 5+gb download can take a long time to give any feedback as to what's happening.

Stock RAM Configuration for 15" MacBook Pro 2.4GHz Intel Core 2 Duo

Hello,
I have a new 15" MacBook Pro 2.4GHz Intel Core 2 Duo on it's way to me and I need to order a RAM upgrade. I know the specifications of what I need, but am getting conflicting information from the retailer on how the stock models are configured for RAM. The total amount is 2GHz. Does anyone know if this amount is provided by one or two RAM modules?

You'll find the RAM is in a 2 x 1GB configuration. Unfortunately they both need to come out for you to upgrade to 4GB RAM in a 2 x 2GB configuration. Still cheaper than going with Apple which makes it a little softer.

RAM For Apple MacBook 2.4GHz Intel Core 2 Duo (13-inch DDR3)

What is the maximum Memory (RAM) supports for Apple MacBook 2.4GHz Intel Core 2 Duo (13-inch DDR3) -
is it 4GB (2GB in each slots) or 8GB (4GB in each slots)

IMac (3.4gHz Intel Core i7) shuts down when sleeps, then won't restart

Just bought a brand new 27" iMac (3.4gHz Intel Core i7) which shuts down when sleeps, then won't restart (ie completely dead).
In order to restart, I have to unplug the power cord from the computer, hold power key down for 10secs, replug in and it then starts up. I returned to the store and they spent a couple days letting it go to sleep etc and overnight and for them it was fine. Woke up no problems. They returned it to me yesterday.
So I set it all up again, left it overnight and this morning it was dead again. So now it leaves me to wonder if it's something I have plugged into it.
I have a new Seagate 3TB external hard drive hooked up using USB3.0. This is plugged directly into the back of the computer.
I also have a powered USB hub plugged into the computer which has regular USB stuff such as printer, graphics tablet and another external hard drive (this one is older LaCie 500gb, and have put it into a new USB 3.0 case as well for the arrival of the new iMac (this had an old firewire hard drive case). However this hard drive is switched off at the case and is not being used.
I believe it could possibly be the Seagate 3TB disk causing this problem, but it works fine during the day while I am using the computer, it's just when I either leave it at lunch time to go to a meeting or walk etc or overnight that I come back and it has shut down....leaving me to believe that it's due to the computer going to sleep.
Has anyone else had a similar problem with a Seagate drive? Today I'm conducting an experiment and heading off for lunch with both hard drives unhooked. If I come back and the computer wakes up from a click of the mouse or keyboard as it should, I will plug in one hard drive at a time and re-test. I will leave the Seagate for last, as I don't think it is the old LaCie disk (which is off).
For reference sake, I also have a NAS running off my network through Airport Extreme etc and have my old iMac hooked up to the network too, but don't believe this is the problem.
Initially I did put in some after market RAM (another 8GB) and though that might be the problem, but I removed and it still reacted the same way (plus store I bought it from again booted up fine and woke up fine at their shop after I had taken RAM out too).
Will keep this post updated with my next test (letting computer sleep without either hard drive in), but keen to hear if anyone has had any similar experiences with Seagate disks/cases and the new iMacs.
Cheers,
Kristin

Hey kristinandmike,
I had a similar problem shortly after I bought my 27" iMac. Here is an excerpt from my discussion:
"As BDAqua suggested, I started the process of elimination by shutting down the externals and just leaving up one of the USB drives and using the computer until time to shut it off. After eliminating 2 of the 3 drives I figured it had to be the last one. That drive is a Seagate GoFlex Desk version that allows different bases with differing connectivity. I had previously used FW800 to connect but had switched to USB3 on the new computer. I went ahead and got a Thunderbolt to FW adaptor cable and switched this drive back to Firewire rather than USB3. So far so good."
For some reason the Seagate I was using didn't agree with the USB3 on the Mac.

Apple iMac 2.33GHz Intel Core 2 Duo (24-inch), how much ram?

How much RAm can i add into a Apple iMac 2.33GHz Intel Core 2 Duo (24-inch), anyone know?

And I do not see any specifications for a White iMac with a 24" screen that is 2.33GHz.
But now I found it...
http://support.apple.com/kb/SP28
You have what normally would have been a 2.16GHz model but with the made to order 2.33GHz upgrade. Memory is...
1GB (2x512MB) 667MHz DDR2 SDRAM (PC2-5300), supports up to 3GB
officially. You have two slots, each supporting up to a 2GB RAM but officially Apple says 3Gigs is the max. Which is an odd number because normally I would expect to see something like 2Gig based on having 1G rams available at the time. However, since they spec 3GB that would imply that 2GB RAMs were around at the time, but they still specifically say the machine can only have 3GB (2GB + 1GB).
Many older systems can support more ram than their official specs due to larger RAMs being released after the support for testing new RAM was done. Apple specifically limiting you to a single 2GB RAM with the other having to be 1GB would seem to indicate there IS an issue with supporting a pair of 2GB rams.
So you can very safely go from 2GB to 3GB by replacing one of the 1Gig modules with a 2GB module. However I can't say for sure if it would work to go to 4GB or not.

I have a MacBook Pro 13inch 2.4GHz (Intel Core 2 Duo, 4Gb RAM, 250Gb HDD, NVIDIA GeForce 320M graphics, SD card slot, up to 10 hour battery life)bought in October 2010 in the UK. The charger has stopped working. Which model and voltage do I need please?

I have a MacBook Pro 13inch 2.4GHz (Intel Core 2 Duo, 4Gb RAM, 250Gb HDD, NVIDIA GeForce 320M graphics, SD card slot, up to 10 hour battery life) bought in October 2010. The charger has been playing up for a while now - the light going out but coming back on when I move the cable a bit - faulty connection it seems. It has now stopped working at all.
Apple UK charge a whopping £65 for a replacement - and the reviews are AWFUL for it!
I need to know which one I need - 45w, 60w and 80w are listed - can someone tell me please? If I'm going to pay this price I want to make sure I get the right one!
Also, is a genuine Apple one available on Amazon UK, does anyone know please?
Any help will be much appreciated.
Meanwhile my battery is going down.....

Thanks for that wjosten. Much appreciated.
I've read here on Apple's site that the 85W version will work, as you say, and that it would run cooler with a 13" Macbook - I have a 13" MBP of course but assume this would be the same with mine. I wonder if running cooler is a good thing (it sounds as if it is) and it would be better for me to get the 85W version than the 60W one?
Then I have to decide whether to pay the (extortionate as it seems to me, though I may be wrong) £65 from Apple (bearing in mind the rotten reviews here of the Apple product), or risk a cheaper alternative from Amazon UK, at around £20 (also with various rotten reviews)... Any suggestions? Please? :-)

IMac 2.0 or 2.4GHz Intel Core 2 Duo

Can't decide if I should get the iMac 2.0GHz or 2.4GHz Intel Core 2 Duo. Will the 2.0 handle Garageband, iMovie and iDVD or will I need to get the 2.4GHz. I do plan to add more memory either way. Will I still be happy with the 2.0 in 3 years? I'd appreciate any input.

I went for the 2.4GHz and I'm very glad I did, it just feels much...quicker. I run iMovie and iDVD all the time and they run very fast and as nice as I could ever hope for. The 2.0 version will handle everything and will handle it well, but the 2.4 version will handle it better...so to speak. Also I think that the 2.4GHz version will last you a little longer if your looking to get a few years out of your Mac (like I am doing as well).

New Corsair ram issues - 2008 Macbook (white) 2.4GHz Intel Core 2 Duo

Just after having a successful (though after some help from the forum) install of 8GB into my mid 2009 MBP I helped my brother install a 4GB (2x2GB) memory upgrade from OEM 2GB (2x1GB) into his 2008 macbook (white) 2.4GHz Intel Core 2 Duo system. Checked and made sure I got the right memory speed and capacity for the 2008 macbook. Here's the memory I recieved http://www.amazon.com/gp/product/B0011UPBMA/ref=oh_details_o00_s00_i00
So since installing even though the system seems to read the memory correctly showing in system profiler that 4GB is recognized and the status reads "OK" the system is crashing
Below is the latest system crash report that I copied from when I had to restart the computer. Any help on what to do or if the memory is bad?
Note: After booting into safe boot. The system is still crashing! (The report below is before the crash in safe boot)

Hmmm I'm not quite sure if I'm ready to conclude that it's not compatible. I mean vendor of ram shouldn't be why it's not working as I just got done installing Corsair ram into my mid 2009 MBP and although had trouble initially was able to figure out (with the help of this forum and a very helpful member: Kappy) that I had an incompatible (for OSX) kext installed on my sytem. The Corsair ram on my MBP is running great now.
Wish I knew how to read the panic report. Anything pointing to something else that may be incompatible or anything pointing specifically to the memory.
I'm not trying to ignore your advice as I'm very appreciative of it, it's just that I was pretty certain that the ram purchased should be compatible as I checked all specifications and noticed the reviews pointing to compatibility.

Does Apple sell memory for Apple iMac 3.06GHz Intel Core 2 Duo (21.5-inch - DDR3) Late 2009 anymore?

I have a 21.5-inch, late 2009 iMac (Apple iMac 3.06GHz Intel Core 2 Duo [21.5-inch - DDR3]) and I need more memory for it. Currently, I have the standard 4GB memory for it (2X2). I wanted to know if Apple makes memory for my model iMac anymore. Thanks!

Buy your ram from either Crucial http://www.crucial.com or OWC http://eshop.macsales.com.
Apple probably still sells ram for your iMac but you'll pay twice the prince and get less for it.
