Is it best to replace ram before plugging in a new Mac or after running it
Will the : " 128GB OWC MEMORY UPGRADE KIT 4 X 32GB PC21300 DDR4 2666MHz SO-DIMMS for 27" iMac w/Retina 5K ( Early 2019 ) " be Compatable for a 2021 iMac . BIG THANKS in advance, Would be nice saving an extra $2K
This feature alone makes this iMac better than the iMac Pro.
Agreed
Thanks for the video. I saw this video and got the courage to buy 16 gb RAM and went on to put it to my new 2020 27' iMac (5k) computer myself.
It originally came with a total of 8 gb of RAM, the two 4 gb RAM units were placed in slots B and D. The computer turn very slow after I downloaded my music and photos. After adding the 16 gb of RAM units, the computer is now working great.
I found that new 8 gb RAM units should be placed in slots B and D and the 4 gb units should be in the slots A and C.
If the 8 gb units are placed in slots A and B and the 4 gb units are placed in slots C and D, the computer shows that it only has 16 bb of RAM, not 24 gb it should show.
placed
So you kept the two 4gb n only added two 8gb ?? If so that’s convenient was worried I had to replace everything completely
hi! i'm thinking about doing this. just wanted to ask now since it's been 2 years, how is your computer working? still good? thank you!
Contrary to what some may believe, Apple does not use some kind of special or faster ram. It's the same run of the mill stuff you can buy yourself.
i is slow ram
m1: are you challenging me?
Is this okay to use two 16+16GB ram sticks(crusial) along with the Apple provided 4+4GB RAM to make it 40GB ? Won't it affect anything !
Shouldn’t affect anything, however make sure to check how fast it is after you turn it on, and mix and match the slots if you have to, since not all layouts will deliver maximum performance
Awesome you just saved me a bunch of time. I watched another guy take apart the whole computer to get to the RAM. Thank you!
Thank you! Learning about & how to do this saved me a fortune. Bless up! ✨
dude, you just saved me $3000cnd. thank you!!!!
Thank you for this video. I looked at several. You were the best. Everything went exactly as you showed us. Have subscribed and given you a BIG thumbs up.
why not combine the ram? i have 2 16 gb sticks and want to know if I can keep my 8 gb sticks to have 40 gb of ram
Why didn’t you keep the ones that came with it for extra 8 gigs?
I'm wondering the same.
Because that would mess with the performance. It's preferable to have equal sizes of RAM on your machine, so keep it either two RAMs of 4gb or two RAMs of 8gb...
AnonymousNut i haven’t understood:S
@@guillettoaparicio13 The Imac came with two RAMs of 4gb each, he bought two more, but of 8gb each, he didn't use the four RAMs together because the performance would suffer a loss, as the RAMs need to operate in synchronicity. Even if the RAMs were the same frequency, their voltage and controllers are, most likely, not. That's why most people end up using the same size, brand, frequency for certain parts of the PC... Small details like these end up making a difference in the hardware world.
AnonymousNut perfect explanation! Thanks you!
Apple applies the “I don’t care tax”
Would you recommend 24GB ram. I found a good deal on 16GB ram, but was thinking of keeping the 8GB thats already in the machine.
it's a little non-standard, but it should work fine
Why not use the 8GB in the two free slots?
Have the same question
Would be the "better" option. Because they are the first slot each of the two different ram channels but effectively it doesn't matter.
I'm guessing it depends on how different the kits are between the new sticks and the 8GB that were included. Looks like the new kit in the video runs at 2666 MHz but at what CAS Latency? Or does the iMAC strictly requires 2666 MHz running at CL19 only? (Effectively making it not matter with the new kit?)
I added 16g to the original 8 and the speed reduced to 2133mhz using just the new 16g it was fine at 2666
they need to be put in order 2 4g and 2 8g not 4g 8g 4g 8g
If that's the case then why does the Apple site says: "iMac (Retina 5K, 27-inch, 2020) DIMMs have a notch on the bottom, slightly left of the middle. If your DIMMs are mixed in capacity, minimize the capacity difference between Channel A (slots 1 and 2) and Channel B (slots 3 and 4) when possible."
Why not keep the original Ram? have a total of 40g? Are you allowed to mix different ram?
Best to have dual or quad channeling. Also mixing DIMM sizes is never good, can cause some instability depending on what you're doing (CAD for example).
I added 16g to original 8g and the speed reduced to 2133 if i had just original 8 or the new 16 it was fine at 2666
Mar Schrammeyer ok, thanks
Thank you!! Just used your video to change my RAM.
Can I leave the 8GB of RAM n there & just add 2 more n the open slots?
I purchased 64GB from OWC, which is 2 chips 32GB each.
Wish I saw this vid before I purchased my 32gb ram iMac. Can I buy a further 32gb ram and upgrade to 64, leaving the ram already in place there or do I need to remove it and replace?
Have a look to see but I bet Apple installed 4x8 Gb cards so you won’t have any free slots. Look in My Mac memory to find out.
Yes, I have the same question? If the 8G’s only comes with the two 4G ram cards but there’s 4 actual slots, can you just add 2 more ram cards in order to increase the 8G’s of ram?
Can you still attached the stock 8gig (2 4gig) on slot 1 and 3? To have a 40gig ram?
Can someone please answer this question
I need an answer too
You can, but your RAM will be working at the speed of the lowest one of your RAMs. Like if your attached 2333hzs rams and 2666hz rams, your overall ram speed will probably be at 2333hz.
@@jacksonwang3974 but if I stick with 2666mhz with the 2pcs 4gig ram stock, and 2 PC's 16gig 2666mhz or 2pcs 32gig ram. It's gonna be 40gig ram or 72gig ram. Is that ok?
@@MrRaychard123 size will be the total of them all, no reduction
Excellent video well produced I rarely say that because I’ve been a Creative Director for 40 years.

Why not add 2 modules instead of replacing? Do all 4 modules need to be the same size?
You should be able to add the memory instead of replacing. At least, that's what I hear all over the place. If you order 32 GB of ram, the total of ram will be 40 GB, is what other videos say.
But, I remember one video, that talked about the order. I think the lower (2x 4GB) should be in the lower slots. The higher capacity rams should be in the top. If I remember right, it has something to do with the speed. Just check the "About this Mac" menu, and look for the clockspeed of the memory modules. They should be 2666 Mhz for the 2020 macs. If it is lower, change the order of the ram modules and see if it changes the speed.
I added a single 32gb to already installed 2 4gb modules and I have now 40gb. seems to work fine.
@@bastawa4569 Apple site says this: "If your DIMMs are mixed in capacity, minimize the capacity difference between Channel A (slots 1 and 2) and Channel B (slots 3 and 4) when possible."
Apple says this on their site: "For optimal memory performance, DIMMs should be the same capacity, speed, and vendor."
@@amerikan ok, I'm just saying my 2x4GB + 1x32GB seem to work fine since August.
Great video but you do not answer the important questions. Can you not add the two new Ram to the existing ones, and if not why not?
BonaventureHope no. There’s only 4 slots. He replaced the other ram with all matching ram.
Jimmy Minhinnett no he removed two and added a different two
I have a black screen after installing my new ram onto my 2020 imac!!! Please help :(
Add to slot 2 and 4 wait it takes about 30 to 40 seconds to start
@@CineFutbolByScarlos thx figured it out a week after researching it.
Appreciate it I'm not really a apple fan but I've realized the advantages for music creation because simply there are better and cheaper software than on windows so thanks
This is excellent information and well presented. My thanks.
WOW thank you for this you've just saved me loads of money
ATTENTION TO DETAIL for all doing a first time upgrade... be sure to remove labels from new ram AND make sure slots are WELL lit to see proper alignment of notch... attention to detail is a must!
The problem I have with the ram is whenever I switch plug in's, it won't turn on. I have to leave it off a good 20 to 30 minutes. Plug it back in and then wait forever for it to start. Once it starts I can turn it off and on as long as I don't change the plug in. Any ideas what this is about? Thanks, great video.
Best informative youtuber:)
Fantastic video! Thank you! I thought these new ones they made it so you couldn't replace it yourself. Such great news for pricing out a new imac eventually.
If you wanted to add ram to the existing 8 would you need to move the existing 8 to slot 3 and 4 to put the bigger modules in 1 and 2, or does it matter?
I heard that’s a better way.
what you just mentioned is the way to go. because if you do 1-3, 2-4, it will clock down to 2133
From the Apple Support page "iMac (Retina 5K, 27-inch, 2020) DIMMs have a notch on the bottom, slightly left of the middle. If your DIMMs are mixed in capacity, minimize the capacity difference between Channel A (slots 1 and 2) and Channel B (slots 3 and 4) when possible." This appears to suggest that to add 2x 16GBs to the stock 4s you should put 16+4 on each channel. ie alternate the sizes.
Cuz the Mac come with 1-3 and if we want to add additional storage we move the ones on the Mac to 2-4 and the new ones to 1-3 ? Is that right ?
Has this proved to be correct, alternating ram sticks as you mentioned, rather than matching pairs or putting new sticks in the top two slots?
Do you know if the SSD is soldered in or if it’s a plug-in module???
plug in only at 4TB model and above unfortunately
dnsxwdn ‘premium’ models 🥺
No for some reason it's soldered in with a huge free space next to it because if you get more than 2TB of ram you need an expansion module.
I’m buying 2 iMacs, can I take the ram from one of them and plug it in the other and upgrade just one of them?
yes! it should work.
Very, very nice video - thank you. Does it make any difference in the performance, i.e speed, if I put it 4 x 8 ram or 2 x 16 ram?
Excellent tutorial very helpful 🎉
Hi I bought one dimm to put in my iMac.
I put this dimm on first slot (top to bottom) and leave the 2 stock dimms
Once you've inserted the third-party ram, what do you do with the Apple ram after it's removed? Where do you store it? Can you sell it or send it back to Apple for a gift card? It would be a waste of perfectly good memory if you don't do anything with it.
Reminded me of the old Dan Quayle quote: "What a waste to lose one's mind. Or not to have a mind is very wasteful. How true that is." Sorry, I digressed :-)
I ordered a 16gb kit from OWC, will I be able to install that and keep my 8gb that came inside my iMac for a total of 24GB of ram?
Yes, you can mix and match in pairs, as long as the matching pairs are in slot 1 and 3 or 2 and 4.
Chris Krowchuk I was expecting the same configuration, but 9to5mac just put out an install video that found that for optimal performance they should no longer be staggered, but rather placed 1 with 2, and 3 with 4. I don’t know who to trust anymore. Staggered brought down the MHz it seems
Chris M Forsyth that’s odd considering Apple staggers them right out of the factory.
@@chriskrowchuk8477 I'm typing this from the 2020 iMac 27 inch with 24GB of RAM. I put the two 4GB Apple Ram slots into slots 1 & 2 and my two 8GB after market RAM into slots 3 & 4 and I'm getting the full RAM speed and it all shows up and works so I'm getting the full 24GB RAM. And i'm loving it.
@@jonsatvoutdoorchannel6686 That's good, if you don' t install them correctly you will lose speed, some have gone from 2666 to 2133 so its good to check you did it right and are getting the full power
My experience with Apple repair/genius is they ALWAYS blame non apple RAM for any issues with the computer. My hard drive died on my macbook and the genius blamed the RAM. I always keep factory ram in the even the mac needs service.
Why not just reinstall the cheap ram that the iMac came with before taking it to to get repaired, that way you don't have to worry about them saying that and still get to saved hundreds of dollars?
I would appreciate suggestions to this question:
I have 2 PNY 1600 8GB Ram sticks with C11 Latency. I want to buy 2 additional 8GB Ram sticks. Cost isn’t a factor.
Should I buy:
2 Motoeagle 1600 8GB with C7 Latency
or
2 PNY identical to the 2 that I am already using
Thank you
I like the new music and graphics!
Very nice video, thank you for saving me a lot of cash!!
Is it single rank or dual rank RAM that is recommended in the iMac 27” 2020?
thanks !!
Thank you so much for the help! I really appreciate it
Great video, even from Belgium
🦉 When Apple switches to their own CPUs we'll probably have to buy Apple RAM from now on.
Yes unfortunately we will have to. Spend the same amount as a new computer just to add RAM. I like Apple, but I don't like them taking away choice. I just bought a new 2020 iMac so I don't need to worry about that for a few years.
Can I pull the extra 8gig ram I purchased from my 2012 iMac 27 and use it in a new 2020 iMac 27?
I wouldn't recommend that, since the 2012 iMac runs on a DDR3 RAM, and the 2020 on a DDR4...
Where did you get that Desktop Background? It's shown on the iMac box, but doesn't appear in the Desktop & Screensaver menu.
THANK YOU.
Hi ! I can’t find rams at 2666 MHz with PC4-21333 on the OWC website. Since this is what apple recommends I’d like to be sure while buying the rams. What exactly did you buy from OWC ? Thanks a lot !
Thank you!!!
Great vid. Very knowledgeable.
thanks, fam
Nice & Thanks :)
amazing sir!
(Sept 3, 2020) - I have a new 2020 27 inch iMac with original (2) Apple 4GB RAM boards. What is the advantage of increasing RAM? Will I notice a performance difference with anything?
🦉 Run Activity Monitor in the Applications/Utilities folder to monitor how much RAM your system is using. if you are using creativity apps like Logic or Final Cut, more RAM will certainly help.
Is 2666mhz slow? Can I add faster one?
Friends, kindly help me to select ram for new imac, im living in India and we not have same stuff as America.
Here is our indian amazon provids:
Crucial 32GB Kit (16GBx2) DDR4 2666 MT/s (PC4-21300) DR x8 SODIMM 260-Pin Memory - CT2K16G4SFD8266
so i plan to get to kits so its will me 16x4=64 Gb.... but what mean this 8 SODIMM?
In advance thanks
Does doing this can void apple care?
Hi, I’ve just ordered 2 x 32gb = 64 which I’ll insert in with the existing 8gb does it matter what order I insert them? Thank yiu
Yes, it matters. According to the Apple site, the first 2 slots should be as close as possible to the capacity of the last 2 slots. So in your case it would have to be something like 8GB | 32 GB | 8GB | 32GB. At least that's my understanding.
😭😭So sad. I just got a new 27’’ 64gb iMac. But I’m going to follow your way to update it in the future. Appreciate!
Any brand its working?
where can i get that knife?
Does this hurt the warranty?
I will be doing this soon. I am purchasing either 2 x32 or 2 x 64. Can I leave the RAM that is in the machine (2 x4 MB RAM) to give me either 40 or 72MB?
No all the rams need to be of the same size. You can’t have a 32 in one slot and a 8 in another, or any other sort of combo. Good luck
That's fucking bullshit.
Very good video. But why you speak like you are out of air???
If my 2017 iMac came with 16GB 2400 MHz DDR4 can I go to 16GB DDR4 at 2666? or do I have to keep it at 2400? Or for that matter could I go to 32GB DDR4 at 3200?
Frequency needs to match i believe.
Good tip andrew
Thanks 👍
can I keep the 8gb that came with it and just add 64gb more for a Total of 72 gb of RAM
same question ^^^^^^^^^^^^^^^^^^^
no , just new ram , take old ram out
Is this ram the same speed and type and all like the originals ?
Yup!
Is a 10gbps port worth it?
Not to me, you'd have to spend big bucks to upgrade your home or office to make it worth it.
What’s the most ram I can add to this so let’s say I buy four 64 gb sticks of ram will it be 256gb ram then
Well ... yes but your cpu probably isn't able to use 266GB of RAM and i don't know which motherboard apple put in here but the motherboard may also not be sufficient enough. I'm not sure but maybe that's why the maximum on their site is just 128 GB of RAM.
I mean if your CPU and motherboard are good enough you could even add 1.5TB of ram like the mac pro.
@@smeshsmesh9695 Thanks that makes sense I was wondering why they put 128GB of Ram.
I did this and my iMac will not restart. So I went ahead and unplugged the cheaper RAM, replaced the original two RAMs in their original slots, and the computer will still not start.
How come you can’t leave the other RAM in there?
Because it will slow it down and can actually mess the imac up they have it on the apple page not to mix owc or any other brand ram with apple ram get all owc or all apple ram which is expensive
Can I use Kingston or GoodRam instead of OWC?
🦉 I recently installed 2 x 8GB sticks in an iMac 27" Late 2013 model. It was cheap as. You can download this app to scan your system & it'll tell you which of their RAM is compatible, then search Amazon, eBay or StaticICE for the best price. www.crucial.com/store/systemscanner
The original pair is still in there for a total system RAM of 24GB. I moved them up a slot so that the new RAM gets used instead. I don't even recognise the brand Apple used. It was made in Korea. But Kingston or Crucial should be safe choices.
Ground yourself & eliminate static electricity by touching a metal tap before handling RAM. There also seems to be a bit of confusion how to pair modules to make the most of dual channel speed: www.ifixit.com/Answers/View/223429/How+to+couple+RAM+Modules+in+iMac+27
SAMSUNG worked for me. Made a video about it.
@@gemwebb Yep, I did so too. Installed 2x16 of Samsung RAM and kept original 2x4. Works great.
if I buy 2x 16 in which slot do I install them
Slot 1 and 3, or 2 and 4. Just don't place together like 1 & 2, or 3 & 4. That's my understanding of it.
Do you have to backup your stuff on iMac before upgrading ram??
@YYZpresto thanks
No need.
Also. Can you use all 4 slots with new ram?
@YYZpresto Thank you
Nice ☺️
I bought owc ram. My iMac is now constantly restarting my iMac is useless now.
Soooo, did you put the original ram back in and restart?
Dear Eddie please update your situation.
can the ram be purchased and ship to Canada
Yup, I just made a video about it for correct ram on amazon.ca ua-cam.com/video/EN8AhcSlaNE/v-deo.html
you sound like jimmy from south park
yeah that would be the peasant way.
clicking the button with how much ram you want like a boss is much better.
you should try it
Sounds like Kermit
Hi. Is there any reason you didn't leave the 8gb in and just add to it? I'm in the process of getting a new iMac and realised the price difference so will need to do the same and was planning on leaving 8gb in, then adding 2 x 16gb. Is that possible?
You don't want to add unevently Ram capacity to your computer. It will cause confusion to the board. We do add for example 32gb of ram, you should get 2 Ram of 16gbs.
Dont mix apple ram with any other ram it's on the apple page just add the 2x16 on slot 2 and 4
@@CineFutbolByScarlos What’s the reason for avoiding this?
Just to let you know there is a T in Twenty, not twenty
