    Hi, Getting ready to pull the trigger on a maxed out new iMac 5K for video editing;
    4.0GHz Quad-core Intel Core i7, Turbo Boost up to 4.4GHz
    8GB 1600MHz DDR3 SDRAM - 4x8GB
    1TB Flash Drive
    AMD Radeon R9 M295X 4GB GDDR5
    Apple Magic Mouse
    Apple Wireless Keyboard (English) & User's Guide

    PROMISE Pegasus2 R4 8TB (4 by 2TB) Thunderbolt 2 RAID System

    I'm ordering with only 8GB RAM due to upgrading to 32GB. I will be selling the 8GB and replacing all with new (4x8GB) RAM.
    I'd like to know what recommendations you may have that's been working flawlessly for you on the new iMac 5K retina? I've been looking at the Crucial, OWC and Kingston. I was set on purchasing Crucial, but I've been reading about some people having issues with it. The following thread is one case in point;
    Thanks in advance for your help. Ray :rolleyes:

    Get 2x8 GB to add to the 2x4 GB and make 24 GB, I doubt you'll notice any difference.

    As for the poster on that thread, they must have received defective RAM. I haven't had any such problem with my Crucial RAM upgrade, you'll likely be fine.

    Mighty nice setup! :)

    Defective RAM is rare, buy whatever is cheapest.

    I can confirm what redheeler posted. A RAM upgrade will likely not make any difference.

    Thanks for the replies...... I'm purchasing the iMac 5K mainly for 1080 and 4k video editing. It seems to me that RAM issues would be a major problem throughout your loaded software, not just to something specific. More than likely most complaints are due to defective RAM right from the factory. I've always felt that RAM is RAM...... but maybe there are better manufacturers than others. I want to get it right the first time if possible. I don't understand why Apple wants the $$ for RAM as they do. In a word "Ridicules" Thanks again, Ray

    And your feeling is right.


    Because they are capitalizing on the fact that people don't know about how much memory they actually need.
    With 4k video it is possible that you will profit from more RAM, but since you can always upgrade later I strongly suggest you see how 8 week for you.
    Come back to this forum and tell how it went. I'll bet you'll be surprised ;)

    If for some reason you need more, just order any old RAM that fits.

    Go OWC. There have been some crashing issues with some of us using Crucial on the 5K.

    I have never experienced such issues.

    But in fairness, the majority of people reporting the fairly common 'wake from sleep' crashes have been using Crucial RAM, at least on this forum.

    Cheap RAM increases the likelihood that crashes will occur.

    If you are editing 4K video, having the extra RAM helps. Might as well give yourself some breathing room. I tried 4K editing with 8GB when I first got the 5K iMac and it worked but after I jumped to 24GB I noticed an improvement.

    Crucial RAM has been working well in my 5K iMac. To be fair however, I did need to exchange the first set of Crucial RAM sticks because they were causing me Kernel panics.

    Personally I have not seen a wake from sleep crash.

    Good to know about the Crucial issues that some are having along with good experiences. In my research (below) OWC is about $100.00 more than the Crucial. Why that much more does intrigue me...... but then again, look at Apple. With that being said, as we all know, someone somewhere will have a problem with any manufacturer. It's the real world user's (you) that I will pay attention to. I sincerely appreciate your input and please, keep chiming in. Ray

    Crucial $263.98 32gb ($336.02 savings over Apples $600.00)

    OWC $364.99 32gb ($235.01 savings over Apples $600.00)

    You have the same setup as I have beside the PROMISE Pegasus2 R4 8TB (4 by 2TB) Thunderbolt 2 RAID System, I did the same thing and ordered mine with 8 gigs and updated it to 32 from Amazon and it works fine.

    P.s on a side note anyone need 16 gigs of ram for a 5k Retina pm me, and I will give you a good price.
