You might have heard plenty of times that it’s better to buy a Mac with the maximum amount of RAM (random access memory). Why? The answer is very easy: there is no such thing as too much system memory. Just consider the fact that the more RAM your iMac has installed, the more windows and/or tabs it can have open at one time without slowing down. Also, with physical memory available, macOS won’t need to resort to using virtual memory, which ultimately slows things down.
Whether or not you can upgrade the RAM in your Mac—and how easy it is to do so—depends entirely on the model. Some iMacs, like all the 27” models, have an access panel specifically for adding RAM. And it takes only a few seconds to pop that panel off. If your Mac has slowed down it's possible that your RAM is being used to the max. Here's how to free up memory on a Mac (or how to free up RAM), including ways to reduce Mac RAM usage without. NVRAM (nonvolatile random-access memory) is a small amount of memory that your Mac uses to store certain settings and access them quickly. PRAM (Parameter RAM) stores similar information, and the steps for resetting NVRAM and PRAM are the same.
iMac RAM upgrades are easy for most models, and it’s a good idea to do it yourself, for two reasons: firstly you’ll get to know your iMac better, and secondly it’s possible to save a few hundred bucks rather than having Apple do the expensive upgrade. There are a few situations, though, where you might need to contact Apple or an Apple authorized service provider to install the RAM. Memory isn't removable by users on 21.5 inch iMacs from late 2012, late 2013, mid 2014 and 2017. Nor is it possible to manually remove the RAM on a 21.5 Retina display from 2017, either. In these cases, sadly you will need to pay higher prices to get the upgrade you want.
How to Upgrade iMac RAM
Upgrading your iMac with more RAM is super-easy and requires only a few steps. The first and most obvious task is to identify your iMac to know which memory it is that you will need to purchase. The price of the memory module will differ based on the iMac model you own.
Apple has guidelines for the maximum amount of RAM each iMac model supports, but upgrade specialists say the devices are capable of supporting more.
While earlier versions of the iMac (17-inch or 20-inch models from 2006) have two memory slots, starting with 2007 models Apple decided to implement four slots instead. However, we highly recommend checking the type of RAM you need to buy, otherwise the iMac won’t recognize it.
Here’s a guideline for the type of RAM you should be looking to buy, depending on your model of iMac:
- Mid 2007 models use 200-pin 667 MHz DDR2 SDRAM.
- Early 2008 models use 800 MHz DDR2 SDRAM.
- Early 2009 models use 1066 MHz DDR3 SDRAM.

It’s worth noting that memory specifications change dependent on the iMac model, and so models after this can include additional sizes of memory. As such:
- Late 2009 iMacs can equip 2GB or 4GB SO-DIMM, DDR3, or SDRAM formats of RAM, running at 1066 MHz in each slot.
- Mid 2010 and mid 2011 iMacs can also use 2GB or 4GB SO-DIMM, DDR3, or SDRAM formats, with a maximum of 1333 MHz in each slot.
Meanwhile, 27-inch models manufactured between late 2012 and mid 2015 with the option to upgrade the RAM each come with a base memory of 8GB, and support a maximum of 32GB. The earlier 27-inch and 21.5-inch models released between late 2009 and mid 2011 support only 16GB of RAM, according to Apple.
Once you’ve figured out which memory types are compatible with your iMac, installing the RAM is easy. It only requires a few minutes, but there is still a slight difference between some models since Apple migrated from one design to another. Essentially the one thing you’ll need for all models is a soft, clean towel or cloth that you’ll place on the desk or other flat surface to protect the display from getting scratched.
The installation of the memory is pretty straightforward: first, you need to locate the memory compartment. On models released between 2006 and 2011 this is located at the bottom. The memory access door is secured by three screws on these earlier models.
On newer models released after 2012, this compartment is located on the back of the iMac above the AC power port. Apple made access easier, and the memory compartment opens with a button. A full step-by-step guide on how to install iMac RAM on various models is available on Apple’s support page.
One last thing that you should be careful with when upgrading your iMac’s memory is the compatibility between each of the individual components. Computer operating systems handle memory in very specific ways, so after finding the right type of RAM for your iMac with the guidelines above you should then try to ensure that you upgrade your system with matching memory.
Why Not Apple RAM
It’s good to have the maximum amount of RAM in your iMac at the moment of purchase, since this is a good way to expand its lifespan. But if you didn’t opt for the maximum RAM, then that’s no problem because you can upgrade it at anytime. And you won’t break the bank, either. In fact, this is the main reason why we don't recommend maxing out RAM at the moment of purchase of an iMac with upgradeable memory. For example, the mid 2017 21.5-inch 4K iMac comes with 8GB of RAM. But if you want to upgrade to 16GB it will cost you an additional $200, while 32GB of 2400MHz DDR4 RAM (the maximum supported) adds another $600. By comparison, a similar non-Apple 32GB DDR4 2400MHz kit costs $250 on Amazon.
In other words, while a factory upgrade is nice as you won’t have to worry about performance for the next ten years or so, it does come at a cost. Opting for a third party RAM upgrade will save a significant amount of cash, and considering how easy upgrading is this is definitely something worth doing.
Best RAM Brands for iMac
With so much choice available when it comes to system memory, it can be a challenge just to pick the one that is right for you. As such, we’ve picked three brands that we think you should consider when looking to upgrade your iMac’s memory.
Crucial
U.S. company Micron Technology can be found among the top ten companies for memory manufacturers; it produces affordable memory modules through its Crucial subsidiary. The company has products in computer memory, internal SSD and internal HDD categories on the Amazon store. If you are eyeing an iMac RAM upgrade, Crucial’s products should be on your list since its memory upgrade kits are well priced. For example, a Crucial 32GB Kit (16GB × 2) DDR4 SODIMM 260-Pin Memory costs $239.99 compared to Apple’s $600. Crucial has modules for earlier versions, as well, and maxing out RAM in an iMac released between 2012 and 2015 would cost you roughly $200 if you opt for four 8GB modules ($103/2 × 8GB).

OWC
Other World Computing’s (OWC) “MaxRAM” Certification Program is often cited by Mac blogs. It’s software that determines the maximum amount of memory supported by any Mac. As a retailer deeply connected with Apple’s platform, the U.S. computer hardware company OWC sells memory modules through its online store, MacSales. Here, besides getting a good quality RAM module, it is possible to find out how much RAM your iMac actually supports based on OWC’s testing results and then go on to purchase the modules. For example, Apple suggests the mid 2010 iMac supports only 16GB of RAM, but OWC has discovered that the actual maximum is 32GB. That means even greater performance for a long time.
Timetec
Timetec, another U.S. memory manufacturer, was founded in 2013 and seeks to provide memory modules to compete with established players such as Kingston, Corsair, Crucial and OWC. Although the Timetec name may not sound familiar to many, the Hynix name does, and Timetec uses integrated circuits from this renowned IC manufacturer. Timetec tries to position itself as a budget-friendly option, and just a quick glance at its products on offer would confirm that to you: while Crucial’s two 8GB RAM kit for a late 2012 iMac costs $103, the same package sold by Timetec comes in at $85.99.
Video Guide and Instructions
If a picture is worth a thousand words, then how much is a video worth? But would you prefer written guidance or a step-by-step video on how to install memory into your iMac? OWC’s online store, MacSales.com, is the best option for easy-to-follow video guides. Here you’ll find detailed videos on how to install memory and SSDs into your iMac and various other Mac products. These video guides deliver just the right amount of information that you won’t find on Apple’s iMac RAM upgrade support page.
Of course, if you have already done a few RAM upgrades then the steps should be familiar, but those upgrading their iMac’s for the first-time should definitely watch the tutorial videos to get an overview of the complete process from beginning to end.
FAQ
Should I Upgrade My iMac’s RAM?
The short answer: yes, definitely. When it comes to performance, any computer’s limits – even the iMac’s – are outlined by its technical specifications. The more RAM you have, the better the computer performs in the long term. To understand the reasons for a RAM upgrade, you should know about its role: random access memory is where macOS, apps and data currently in use by the system are stored. This enables quick access to that data by the computer's processor. The advantage of RAM is that it is much faster to read/write from/to than other storage type in your Mac. But when your Mac reaches the physical limits of its RAM storage, it turns to the system’s virtual memory, which is much slower since it utilizes the startup disk. If this happens then you’ll certainly notice your Mac running slow.
Does Upgrading My iMac’s RAM Void Warranty?
Performance slowdown is a very good sign that your iMac deserves a RAM upgrade. If you have AppleCare+ or the one-year limited warranty is still valid, then know that upgrading memory doesn’t void warranty. Unfortunately, this claim is only valid for iMac models that allow the user to replace the memory. If you opted for – as an example – a 21.5-inch iMac (late 2013 model) then sadly the only warranty-acceptable option for RAM upgrades is via Apple-authorized services or Apple itself. But upgrading RAM on the 27-inch model from the same year, for instance, can still be performed manually at home without ruining your warranty. As such, before jumping on the RAM upgrade hype-train, be sure to always check Apple’s support page to identify what is possible for your iMac.
How Much Memory Does My iMac Need?
Every iMac comes with a minimum amount of memory that it needs for even basic performance. But that’s mainly optimized for the operating system released in the year of that particular iMac’s launch, and as technology and operating systems advance the physical limits of the installed memory modules are reached more quickly. Although Apple has done a great job of optimizing macOS for earlier Mac models, there are still going to be more issues with their limited hardware resources as the machine gets older.
Also, while Apple suggests a maximum amount of supported RAM on every iMac model it releases, as OWC’s tests have shown these machines are capable of recognizing up to twice as much as Apple’s guidelines. The more memory your iMac has, the better the computer’s performance and longer its lifespan.

Optimizing RAM Usage
Still, having the maximum amount of RAM under the hood doesn’t mean you don’t need to pay attention to the remaining details for optimal performance. If this means a change in usage habits, then consider it well worth the investment.
macOS has a very good memory management tool called Activity Monitor, which allows knowledgeable users to keep an eye on resource-demanding applications. But if you want a similar experience that is packed into a more convenient and visually appealing user interface, third party Mac optimization apps can help to manage memory usage.

Well, you could get the newest Apple MacBook Pro with shiny Touch Bar and speedy SSD storage, and perhaps donate, give away, or simply re-sell your old Mac for the residual value (take these steps if you do).
But, there’s another cheaper yet simpler alternative – you just need to upgrade the RAM (Random-Access Memory), a component of your computer that works in tandem with the drive to load data and quickly complete operations. You can learn more about it from this Wikipedia page.
Inadequate RAM will severely delay the response time of your computer, and upgrading the RAM can make your Mac last a bit longer than if you stuck with the original specs.
Below you’ll find our recommendations on the best RAM for MacBook Pro, covering models from 2008, 2009, 2010, 2011, and 2012. Please note that models after 2013 have non-removable memory thus can NOT be upgraded.

These upgrade options were chosen based on their brand reputation, warranties, and reliability. Some items have advanced features such as overclocking while others are widely known for their resilience and speed. You can learn more below.
Who Should Get This?
Should you upgrade your Mac by adding extra RAM? We recommend that you ask these questions first:
- Does your laptop run significantly slower than when you got it?
- Does it freeze more frequently, or struggle with resource-intensive applications like Photoshop and iMovie?
- Does your display frequently only partially load?
- Has multitasking become too taxing on your computer to do effectively?
- When booting your computer, does it take an excessive amount of time?
If these sound like issues you’re currently experiencing, you should consider upgrading RAM to get more out of your MacBook. However, before you purchase any RAM, there are several things you need to pay attention to both in regards to your machine and your purchase.
First, check that your RAM is upgradable with this list of user-installation friendly MacBook Pros from Apple. You’ll also want to check the RAM you currently have by opening the Apple Menu and choosing About this Mac. From here, you’ll see a brief overview of your machine, complete with RAM specifications.
Second, make note of how much memory you have, the frequency, and the DDR. You may also want to check if you’re using both or one of your RAM slots by choosing “Memory” from the header.
Teamspeak for mac. Keep in mind that you MUST check Apple’s list to know how much RAM your computer can handle. While you can theoretically install more, it is not recommended.
Upgrading RAM will be less useful to those of you who are either not experiencing any of the issues mentioned above, do not engage in frequent multitasking or run apps that are resource intensive, or who are simply looking to make a fast Mac faster (an overkill!).
Buying Extra RAM for MacBook Pro: What to Consider?
Now that you’ve learned all the pre-cautions and probably figured out whether you’ll benefit from RAM upgrade. In this section, we’re going to talk about things you should consider while choosing the best options for your MacBook Pro. Yasu for mac. Most (except for the much older models) require DDR3 RAM in a particular speed (Macs shipping with newer RAM do not support user-installed upgrades). Since you don’t have much flexibility in that regard, other factors become more important when making a decision.
Brand
While it may seem superficial at first, the brand name carries a lot of weight when it comes to computer parts. Trusted brands have tested their RAMs to make sure they work effectively on your computer, and you should avoid purchasing from a less reputable brand in exchange for a price cut.
Warranty
We don’t like to think about what can go wrong, but warranties are important when it comes to the investments you’ve made in your Mac. Make sure to purchase RAM that features a warranty enough to cover you for at least several years.
Reliability
Most RAM from well-known brands won’t have issues with reliability, but you should always read reviews of those who have a similar system to you just to make sure that your risk of errors is minimized. You’re also going to want your RAM to last a while, so doing good research is a must (that’s also why we spent hours to make this buying guide available.)
