How to upgrade ram for iMAC 21.5" i5 mid 2011

I recently purchased a 2-4 8GB ram kit for my iMac. Unfortunately, I ordered the wrong kit, one for a mid 2012, rather than one for my mid-2011.
I'd like to get some advice before I buy another kit.
My mid-2011 iMAC came with 4GB (2x2). That is nearly full now (~3.8 GB). I had thought an 8GB update (a 2x4 kit) would cover my needs. Unfortunately, I ordered and received the kit intended for a mid 2012. Okay, chalk it up to excerience. Experience also tells me to ask for help--HELP!

It also answered my first question.
Now that I'm feeling a bit more confident, I'll ask one more:
Maybe instead of adding two 4G sticks, I'd like to considder replacing the existing 4G (2 2x2s) with four 4G sticks. Is there a limit to how much ram the rest of the computer can support?
Thanks again for the prior reply, And thanks to OWC for the clear and simple video!

How to upgrade RAM in iMac 2013 models

how to upgrade RAM in iMac 2013 models. I know one can ask for RMm upgrade while buying iMAC from online store. Is it advisable to upgrade the RAM by self or from some professional?

Even if you do get the 27", RAM installation is a PTA to install. Prior to setting up your computer on your desk, you must lay it it face down on a soft area (couch). Then you have to maneuver your hand & fingers either around or under the pedal to pop open the RAM door. When putting the RAM into the slots you need to use all of your God given muscles to get them in there. Otherwise, while you are seating one RAM, the one next to it will pop right on out.
When you hear the "snap," the RAM is seated properly and it's neighbor(s) will not pop out.

I upgraded RAM to 16gb in my i7 mid 2011 mac mini and it shuts down at night

I have a mid 2011 mac mini i7. Below are the specs on memory, hardware, and solid state. I also have Yosemite installed - everything is current. version 10.10.2
I've had 8gb installed since I bought it. And I just purchased 2 sticks of Crucial RAM 8gbx2.
Everything is fine but when I go to bed and wake in the morning, the system will not wake-up. I have fresh batteries in the keyboard and mouse. The system mini is warm on top - not cold or hot. So it does not seem asleep. I have pressed the button on the mac mini once and thought it was alseep...nothing happens. I just can't get it back up after it seems asleep at night.
The only way I can get the system going again is pulling the power plug. This has happened each night since installing the RAM. Oh, I also have held the power button down for 5 seconds trying to do a hard reset. Nothing
I was really excited to get the system up and running with 16gb but hate trouble. I am not a tech expert....
I have not changed any settings. And if it was asleep, why isn't it waking?
Does anyone have any ideas here?

Thank you for your help.
I did both resets you offer in the link above and then I went to bed last night.
In the morning, when I hit the keyboard, it paused and came to light....and said there was a problem and it automatically reset and re-booted from a blank screen (not main screen). This was the screen after the reboot. The full error info is listed below the image.

Replacing RAM in an iMac (21.5-inch, Mid 2011)?

Can I install 2 x 1333MHz DDR3 SDRAM (2 gb) and 2 x 1333MHz DDR3 SDRAM (4 gb) together in an iMac (21.5-inch, Mid 2011)?

I have to admit that I do not know - I rely on OWC to have the correct RAM I need. Since you got me curious, I chased around for specs:
Here is the specs from Apple:
No mention of either there; OWC lists SO-DIMM. And Crucial doesn't mention anything either.

I have a iMac 21,5" Intel mid 2011 and I need to know if is possible I change the original 500Gb HD for a 512Gb SSD? If yes, where I find a tutorial about this? Thanks a lot and best regards all.

Hi people,
I'm typing from Brasil, sorry my English.
I have a iMac 21,5" Intel mid 2011 and I need to know if is possible I change the original 500Gb HD for a 512Gb SSD?
I intend to keep the original DVD driver and install the SSD in the same HD place.
If yes, where I find a tutorial about this?
And I will like to know if the 512GB Solid-State Drive Kit for Mac Pro is compatible with iMac.
http://store.apple.com/us/product/MC731ZM/A/512gb-solid-state-drive-kit-for-mac- pro?fnode=5f
What brand and model of SSD do you recommend?
Thanks a lot for now and best regards all.

Since the late 2009 iMacs came out, replacing the hard drive has caused the internal Hard Drive Fan to start running at around 6000RPM.
This is due to Apple replacing the external Hard Drive temperature sensor with a proprietary firmware and using the drives internal sensor.
Replacement drives do not contain the firmware to deliver temperature data on the temperature sensor cable.
When the iMac does not receive a good signal from the hard drive it puts the fan at full speed to protect the drive.
If you replace your drive, your iMac will initially seem fine, but soon the fan will begin to speed up to full speed. Resetting the SMC (System Management Controller) will have a temporary effect, but again the fan will speed up.
Fixes people have used in the past included:
Using smcFanControl and the terminal to set a MAX speed for the fan and writing scripts to start this after every sleep/restart.
Shorting the temperature sensor cable (Not a possibility on 2011 iMacs) this tricks the iMac into thinking the drives temperature is very low, hence slow fan speed.
Both these fixes are less then perfect and leave the drive in a dangerous situation with no protection from overheating.
Another option people try is other Fan Control software. These programs will not work for this particular issue as they often only control the base speed, and if they do control the fans actual speed they rely on the temperature reported by the sensor which is now incorrect.
HDD Fan Control
HDD Fan Control works to fix this issue by reading the drives internal temperature using the S.M.A.R.T protocol and set the fans actual speed to a value good to protect the drive.
It runs at startup and continually to always control the fan correctly, prevent the loud fan noise and protect the drive from overheating
Instead of HDDFan Control, get the free SSDFan Control

How do I download Windows 7 64 bit drivers for my new MacBook Air (Mid 2011) from a Windows 7 PC?

How do I download Windows 7 64 bit drivers for my new MacBook Air (Mid 2011)? I have already formated the HD and preformed a clean install of Windows 7. Perhaps I did this too early. I have read I need to install the drivers from my OS X DVD, however, OS X Lion does not come on a DVD! I've also read that I can download OS X Lion from the App Store and burn it to a DVD, however, all I have are Windows PCs which don't support the Mac App Store.
Is there no way for me to download these drivers from a Windows PC? I know they exist. However, you are supposed to download them through Boot Camp in OS X when you are creating a new Windows 7 installation. I'm I stuck?

I am pretty disappointed in the lack of documentation.
This is the Apple Support page for Boot Camp:
http://www.apple.com/support/bootcamp/
No mention anywhere of Lion, of 4.0/4.01
In the past, 10.6.6+ was suppose to - and sometimes did - provide for a download drivers from within Boot Camp Assistant program, in order to save them to flash or such (that should be about 1GB, too large for CD). Some macs req'd a USB-DVD or other driver that was needed pre-install of Winidows
You don't install Apple drivers until after Windows is installed otherwise,
It is possible for me, with a tower, to run w/o needing any drivers from Apple. But with laptops, mini, you do need some drivers from Apple for graphics, internet, wireless, SMC support.
And right now, loading any Apple support Tech Note articles is very very slow.
People keep asking why Apple can't post 3.0 or 4.0 like they do the updates. Only logic is to force t he download from inside OS X or from an OS X DVD. Otherwise would be here, and avoid all the trouble. they aren't of use on a PC, and any PC motherboard vendor does post their support software for download.

Thank you

I think Apple has reacted to a perceived---or actual---"dumbing down" of the user base. When new Macs shipped with disks, all too many people either blindly threw the disks away of lost them. There are posts all over these forums from people who no longer have their install/restore disks. Some can no longer get proper replacement disks becsue their computer is too old and Apple no longer has a stock of that model's disk.
This is not unique to Apple. PC makers are doing the same thing--providing a restore function internally.

Make sure you are using the latest version of Adobe Flash Player
Check Flash Version
Adobe strongly recommends that you first uninstall any previous version of Flash Player, using the uninstaller:
http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-mac-os.html#main_1 0_4
Follow the instructions closely, such as quitting ALL applications first before installing. Repair permissions and restart your computer after the installation is completed.

Since I cannot read German, I was wondering if there was some sort of "Help" listing at the bottom of the website you linked? If so, there should be a section or a FAQ section that should tell you what you need and/or the system requirements to watch their streams & videos.

TS5167 iMac 27 Inch from mid 2011 with screen display issues

I have a iMac 27 Inch from mid 2011 with a 2.7Ghz Intel Core i5 processor and a AMD Radeon HD 6770M 512 MB video card. The screen has started to go dark on the left side whilst the right side is normal. Has anyone else had this issue? Is it the video card that is defect?
Thank you

Hello! I have a problem with the video card radeon 6970M, is the one that is described in this article ((((I'm from Ukraine, and I purchased my iMac 27 " in the United States. Can you do something to help me with this problem? In Ukraine are now very expensive to change the video card on the iMac, the dollar is very high, a new video card will be very expensive for me. I can't work right now on my computer (((
