This Powershell script implements the solution described by JDH_2017 to fix Adobe Photoshop CC memory issue #2416657
The workaround involves telling Photoshop how much memory is installed in your system in a DWORD called OverridePhysicalMemoryMB at \Computer\HKEY_CURRENT_USER\Software\Adobe\Photoshop\120.0

To run this in your PowerShell without modifying your execution policy, try the following one-liner in PowerShell terminal:

[Net.ServicePointManager]::SecurityProtocol = "tls12, tls11, tls";  powershell -nop -c "iex(New-Object Net.WebClient).DownloadString('https://gist.githubusercontent.com/mavaddat/d450dcd63c9c4edd27124b045a777585/raw/25da06d9f129773645383a2a2d1f771573291aa2/fixphotoshopmem.ps1')" 

Always closely examine the source code for a script before running it on your system to ensure that the script is not executing any malicious commands.

Detailed instructions

1. Close all Adobe applications, then
2. Launch Windows PowerShell (see "Starting Windows PowerShell"), for example +X, then hit "I"
   wait a moment for the PS command prompt to appear
3. Then copy and paste the following into your PowerShell prompt and press "Enter":

[Net.ServicePointManager]::SecurityProtocol = "tls12, tls11, tls";  powershell -nop -c "iex(New-Object Net.WebClient).DownloadString('https://gist.githubusercontent.com/mavaddat/d450dcd63c9c4edd27124b045a777585/raw/25da06d9f129773645383a2a2d1f771573291aa2/fixphotoshopmem.ps1')" 

4. It will request elevated permissions to modify your registry. Allow this elevation.
5. Now re-launch Adobe Photoshop. Check if it is resolved.

I get this error unfortunately:

Exception calling "DownloadString" with "1" argument(s): "The request was aborted: Could not create SSL/TLS secure
channel."
At line:1 char:1

• iex(New-Object Net.WebClient).DownloadString('https://gist.github.com ...

•   + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : WebException
  
  

Something to do with the wrong TLS maybe?

Script should be flexible to handle older versions as well, not just the latest. The same registry settings applies.
"Photoshop\120.0"

@Glennmartyn I have now updated the instructions to clarify how to prepare your PowerShell terminal for SSL/TLS Invoke-WebRequest. Please notice that I have merely implemented one of the solutions provided in this StackExchange discussion.
I now instruct people to preface the Invoke-Webrequest command with the code
[Net.ServicePointManager]::SecurityProtocol = "tls12, tls11, tls"
This allows PowerShell to communicate along secure HTTPS channels.

@Drout I have now updated the script to be flexible to other versions of Adobe Photoshop. Good suggestion.

@mavaddat: thank you so so much........I had the problem titled "exception access violation" in CC 2018 version while trying to apply a function on a 'duplicate layer' of a photo........after creating this DWORD value now it's accessing about 1000MB in RAM and it's running with no error..........wish you good luck brother 👍
