@RSimmons09 - You have to be logged into the forum first. Click Reply to a post in this thread and you should see a Camera icon on the toolbar in the window where you'd type the new post.
Click that icon and a Photo box appears. Open the folder where the image is saved in a new window and just drag the jpg you want to share into the Photo box and click Done. That should take you back to the box where you are creating the new post.
NOTE: Images have to be approved by the moderators, so you may see it in your post in this thread immediately, but we'll only see a "placeholder" until the image has been approved, which may take a few hours or a day...
@RoHe , How do I paste or insert a screenshot jpeg? It says I don't have permission.
After reading the article that @Vic384 referenced I wonder if the 8GB single SDRAM was dual channel? (That was 1 year ago). I'm thinking that it now sees the three SDRAMs and only reports the matched pair as dual channel and not reporting on the single SDRAM as there is only one field to report the channel mode.
My advise to you is populate RAM slot evenly, 1st pair on white TAB, if need second pair on black TAB. Do not use odd number, use in pair with matched speed, size, frequencies and CL. If you need 32GB use two 16GB on white TAB, don't use 8GB on all banks, this adds more chips, mean more delays.
@Mr.Byte While I agree with you on the 32GB configuration, that is not what is in the Dell Service Manual or the Setup and Specifications. Many in this forum have had success with two 16GB modules so perhaps Dell should update their documentation. It was not that long ago that the documentation did not have the single 8GB or 16GB module configurations.

@Vic384 Having a single RAM module running in dual channel mode is contrary to everything written about dual vs single channel mode.
I'd like to see a screenshot of CPU-Z when @RSimmons09 has only that one single RAM module installed...

@RoHe & @RSimmons09 Here is a post where the user had a single 16GB memory module and he happened to post an image of the CPU-Z results (not Channel # = Single). https://www.dell.com/community/XPS-Desktops/XPS-8910-why-ship-ONE-16GB-instead-of-TWO-8GB/m-p/7436129

@Vic384 - That's why I asked @RSimmons09 to post a jpg of CPU-z showing the channel mode with only one RAM module installed...
Call me "Skeptical"...
