    Crucial has done it again! Fantastic Kit!
  

*by L***N on Reviewed in the United Kingdom on 11 June 2018*

I have always been a fan of Crucial Memory as they are always of high quality! After doing research on what RAM specs I would need for my 15inch MacBook Pro, I decided to buy from Crucial and as usual they did not disappoint! High speeds and of great build quality!I bought it for my MacBook Pro (Mid 2012) - Model Identifier (MacBook Pro 9,1) to go with one of the 2GB RAM sticks already in the machine! Now I have 10GB of RAM and has brought a new life into my 6 year old machine!Only thing with Macs is that I would make sure that you get the right RAM for your machine. Crucial offer RAM sticks for every Mac on the market (That has physical RAM Slots) so make sure you buy the right one! Check the model number of the RAM needed as well as the clock speeds! Can check on the OWC repair website as they tell you the RAM you need to get for the machine you have!Simply take off the back cover of the Mac after removing all the screws holding it into place, then simply take out an existing RAM stick (if there is no space - mine had two 2GB sticks in it so I had to remove one) and then slot in your new Crucial RAM! It is so simple and works right out of the box!I have heard from some people that it took over 10 minutes to boot for the first time after initially putting in the new RAM stick, however I didnt have that problem and was able to boot pretty much straight away. If you do have this issue, it is common and just let it load as it might take a little while, however that will only happen the first time you install the new RAM stick and not every time you boot as the Mac is just checking the hardware of the machine.Totally recommend Crucial over any other RAM brand I have ever used! Cheaper than many competitors, however still with an amazing build quality and performance!

    Worked perfectly in my iMac 27" (Late 2012 - 3.4GHz Core i7)
  

*by C***Y on Reviewed in the United Kingdom on 28 March 2013*

Bought my iMac March 2013 from Apple Store and configured all extras apart from additional memory because the store price from Apple was extortionate and I had researched on YouTube how easy it is to replace the memory in the iMac 27" model (unlike the 21.5" model).  I ordered 2 kits totalling 32GB (4x8GB) because the iMac 27" has 4 memory slots.  They arrived promptly and were well packed in sturdy plastic cartons so the modules were well protected and a little tricky to get out but if you pop them out from behind you won't damage them - just make sure you discharge any static and always hold the modules on the edge. I suggest leaving the modules in their packaging until you have removed the memory module cover on the back of the iMac.To install the memory modules you need to lay your iMac screen down on a flat surface (use a soft cloth to protect from scratches - an empty pillow case works just fine). Remove the power cord to get access to the little push button to release the memory module cover.  I used the flat end of a screwdriver to push this in hard in order to pop off the cover.  Once opened there are two catches holding the existing memory in place (in my case 2x4GB). Pull these catches towards you to release the grip on the modules.  Carefully pull out the modules one at a time.  Remove all modules before installing any new ones.  Now install the new memory modules using the reverse technique.  There is a little notch along the edge with the pins so it's impossible to install them the right way around.  If you buy more than 1 pack I would recommend you install each pack together i.e. don't mix them in the slots.When installing my modules I found they were a really tight fit and I had to force them in.  This could be down to the positioning of the notch above.  It seemed easier when installing the modules in the slots from which I took out the old memory.  Perhaps the engineer at Apple had the same problem and once forced in initially they become easier to install.  I did try to pull them out again but they seemed to be stuck fast...so didn't try again on the basis I've maxed out the memory so don't intend to remove.Push the leaver forward once all modules are installed - it won't click into place if you have not properly installed the memory per the above.  Clip the memory cover back in place and power on your iMac.  My beeped repeatedly first time suggesting the modules were not fully clipped in. I opened back up and push each modules firmly back in their slots, replaced the cover and booted up again - BINGO all 32GB recognised and has been running sweet every since with no reported system issues and boy coupled with the Fusion drive I spec'd this machine now flies.I looked at several different supplier included non-Apple certified modules from Crucial but decided that if I am going to spend £150+ on memory for an iMac that cost significantly more then it's worth paying the extra to have the reassurance that Apple engineers have certified these memory modules for iMac.  It was a toss up between Corsair and Crucial but on the whole I felt that more customers provided positive review comments for Crucial (not just the star rating) and besides when I upgrade my MacBook Pro memory recently I purchased Crucial and have not had any issues with them for over 18 months now.As others have stated on reviews before if you already have 16GB then the performance uplift from 16 to 32 will not be as noticeable as the jump from 8 to 32 obviously but improving your iMac memory by 50% has to be a wise investment given that memory is one of the most cost effective and only ways of upgrading an iMac 27".For gamers out there the main reason I pushed memory up to 32GB was to run some of the triple A games at high frame rates.  I spec'd the NVIDIA GeForce GTX 680MX 2GB and this machine now runs Gotham City, COD Black Ops etc flawlessly.  Running video editing and ripping software along with multiple other office applications concurrently now is a breeze with no noticeable slow down - and I multi-task heavily with workflow on my iMac.
