Installation and layout - by the end of 2015 iMac 27 "5K of RAM

Ordered a new mac (end of 2015 iMac 27 "5K retina) with 8 GB of ram (2 x 4 GB).  I bought from another 2 x 4 GB of ram to do the 16 GB mac. What is the optimal layout for the 2 pieces of stock and 2 additional parts:

1, New1, Stock 2, 2 new stock or

Stock 1 Stock 2, 1 News 2 news

Or it does not matter? Does it affect the double channel because they are 2 pairs?

Thank you

It's incredibly simple, install new RAM in the empty slots and that's all you need to do. Nothing to worry about at all!

  • Can I install more memory on end of 2015 iMac?

    Can I put my 8 GB memory at least 16 GB on my iMac end of 2015? I'll even take to the Apple store and ask them to do so is possible. I sort of remember, however, that memory upgrades are impossible to do on the end of 2015 iMacs.  I'm playing the game Blizzard on my Intel Core i5 Overwatch to 3.1 GHz with 8 GB of memory. Parallels (virtualisation company says that I need more memory in this game of Blizzard. I am disappointed that I bought this game, Parallels desktop 12 and 10 Windows and can not play. Leah

    As a side note: why Apple does not have a computer game descent?

    Thanks for the help,

    Only if you have the 27-inch model. The 21-inch models cannot be upgraded. However, you can view at OWC to see if they upgrade kit for DIY with a video tutorial. I don't know if they do it, but you can check with them.

  • I can't get updates since SP2 installation and update of the Windows Update Agent.

    I have Vista Home Premium 64-bit.  I have done 3 installs clean for several days and each time I install SP2 and update the Windows Update Agent I can't get updates.  When I click search for updates, it just keeps looking for hours and hours and never stops looking.  I tried several solutions on the internet, including those found here.  Of course, the first thing I did was run the Fixit of Windows Update tool.  He could not solve any problems found.  He gave the error code 0 x 80070005.  I installed the SubInAcl.exe and run several different command text and a text of the batch.  The batch text did nothing.  The texts of order had errors of syntax and a file, he could not access.  I ran the System File Checker, and it finds errors, it could not fix.  I just did a clean install on this machine 6 or 8 months ago because I was going to get rid of the computer, so when I put in place I used the username user.  I came across no problem at all when I installed the operating system and update everything.  Since then, I decided to keep the computer, so I wanted to have it in my name.  As I said, this is my 3rd try.  I am willing to give.  Maybe someone here can help.

    I tried two clean installs and I get the same thing.  Once I have installed SP2 and the new Agent update, I can't get more updates.  It keeps only the search for hours without results or error messages.  I tried all of the suggestions I found on the internet, but nothing works.  I get always the same error code 0x80070005, when I run the Fixit of Windows Update tool.  There must be a way to solve this problem.  Why I was able to do a clean install of 6 or 8 months without any problems, but now I can't.  It makes no sense at all.  I really hope someone who knows the answer reads this.

    I finally got it!  I tried two other proposed solutions, then I ran the System File Checker, which is no problem, then I ran Check Disk.  Check disk found and repaired files in the file system of BITS among others.  After that, I'm now completely up to date with Windows Update.  I was ready to give up.  I'm glad I did not.  For anyone else having similar problems, don't give up, the answer is there.

  • WMP will open the VTS_01_1.VOB and stop at the end of this file

    I don't know if this is the place to post this question, but it's here.

    I created a web page that lists the cover images all my DVDs that I have on an external hard drive and each cover image is related to the first file VTS_01_1.VOB for this DVD.

    I test page to see how it works for each device I have.  The page works perfectly with my tablet from Samsung, the player on the Tablet, I installed automatically go VTS_01_1.VOB, VTS_01_2.VOB and so on until the movie is done.

    If I use my pc Windows 7, WMP will open the VTS_01_1.VOB and stop at the end of this file, how can I get WMP to continue to the next file automatically?

    Personally, I would check the source code of the Web page of the first.

    Paste the full path to the video_ts.ifo file in a new MS Word document and save it as htm.  Then run the file [it should open in your default browser], then right-click on the page and select view source.  Find the link - it should look like

    href ="... / SomeFolder/VIDEO_TS. IFO "> D:\SomeFolder/VIDEO_TS." IFO

    assuming that D:\SomeFolder/video_ts.ifo is the text that is displayed for the link

    Then go to your actual Web page and discover its source to verify that the link contains this model.

    If the solution is not as simple as that, then you will need to post a question in the section Web & networks of this forum I don't know enough about writing for the Web page.

    To increase the chances of getting there help please include a description of what happens when you try to click on the link - rather than 'will not work.

    I can create a branch to several branches then have a quiz and evaluation at the end of each branch?

    The situation: I have 10 roles taking the same training.  each will have to branch halfway through and take their own quiz.  It needs to report on completion of 80% of cornerstone LMS.

    You can take a look at a use case in this blog: branch aware Quiz - blog of Captivate

    If you can deal with limitations of navigation because of the current branch, you will see that it works very well.

  • End of 2015 iMac 5K Calibration of the retina

    Hello. I have an iMac end of 2015 with the retina from 5K to the address 27. I do a lot of photography and want to calibrate the screen. Unfortunately, the calibration in the system preferences window gives me no option to set the display, other than the white point and the brightness. No point buying a third device of calibration of the party if I can't make actual adjustments to the screen.

    Am I missing something here? Or is it pretty well "our color is the right color" Apple? It seems to me that I had more control on other views of Mac in the past...

    Hello!

    It is hidden. Please press option while clicking on calibrate and you're done

    Let me know.

  • Towards the end of 2015 memory 27-inch iMac

    Just got my iMac to 3.3 GHz 27 inch end of 2015 and looked at the memory already installed.  A bar of 4 GB of ram is installed in Bank 0 and Bank 1 is the other 4 GB of ram.  Just put two 8 GB of ram, 4 GB and 8 GB is in Bank 0, and the other 12 GB are in Bank 1.  Is this correct?  I thought that the ram was supposed to be the same size and type in each bank memory, for example 2 x 4 GB in Bank 0 and 2 x 8 GB to Bank 1.  The iMac doesn't seem to object and it seems the tests when it starts.  Help much appreciated. Marie.

    Simply put the RAM in both slots empty and you will be fine. Don't resist it.

  • Everything by opening a new tab with the Alt + Enter command, is it possible to open next to the current tab and not in the end?

    No indication on how to achieve this will be very welcome.

    There is not an integrated framework for the opening of new tabs "unrelated" everywhere except at the end of the tab bar.

    Various add-on authors tackled this request over the years. It is not really clear to me that these extensions are still working, but you might check the reviews and see what you think. (I have not tried these myself)
