Of course, doing so will void your warranty, so it may not necessarily be worth the risk. These days, if you want to attempt a DIY RAM upgrade on the 21.5-inch iMac, you'd need a lot of experience and a special upgrade kit, something like the ones iFixit sells. I bought an extra 16gb of ram from owc but I cant figure out the best way to put the sticks in. I just bought a new 2015 27' imac that macrumors linked to last week. RAM was relocated under the logic board, so it was no longer accessible without taking apart the entire iMac. Did you figure out the best configuration I've been using the same macbook pro since 2011. The 21.5-inch iMac is still off-limitsīack in 2012, Apple shut off aftermarket RAM upgrades for the 21.5-inch iMac. Each time, I postpone a RAM upgrade until I need it, which gives me time to save up a little extra cash and keeps me from spending money unnecessarily. The result is JEDEC-compliant memory that’s a perfect fit for a faster Mac.
We start with the highest-quality components, and then create memory to the exacting speed, capacity, and programming specifications of nearly every upgradeable Apple computer. I've done this with two 27-inch iMac computers. OWC memory is specifically engineered for compatibility with your Mac. You're good to start with the lowest RAM and upgrade later when you're ready.
You may want a different supported brand of RAM than what Apple puts in the iMac by default. It turns on fine and randomly it turns off, makes a loud screechy noise or other weird problems. On OWC it states my model supports 48 GB of RAM. OWC 48 GB ram messes up iMac retina 5k late 2015. You may not need more than 8GB of RAM to start but will want to upgrade to more a year from now. OWC 48 GB ram messes up iMac retina 5k late 2015. 1 B (bel) 10 dB (decibel) K v is the statistical adder for computing upper-limit of A-weighted sound power level. L p A,m is the mean A-weighted sound pressure level measured at the operator position (rounded to the nearest 0.5 dB).
We also have a guide that shows you how to replace the RAM in your 27-inch iMac.Īpple-installed RAM can come with a hefty price tag. L W A,m is the mean A-weighted sound power level, rounded to the nearest 0.05 B.
That means you can buy additional RAM any time you want, long after you've bought your new iMac, and install it yourself. The 27-inch iMac, on the other hand, is the only iMac that allows for aftermarket upgrades to RAM. The 21.5-inch does not allow for post-purchase upgrades without invalidating your warranty. One of the biggest deciding factors for some people have in figuring out whether to buy the 21-inch iMac or the 27-inch iMac is aftermarket upgradable RAM. The 27-inch iMac still has a backdoor for RAM
