I had the same problem and was the "virtual memory" ( i call it page file or swap file.... ).
Try this commad in to powershell if the value is lower than 16256 you didn't set it correctly.
Command:
Get-WMIObject Win32_PageFileSetting
Output example:
PS C:\Users\admin> Get-WMIObject Win32_PageFileSetting
MaximumSize Name Caption
----------- ---- -------
16256 c:\pagefile.sys c:\ 'pagefile.sys'
Hey,
Am back after a long nightshift.
So I've tried this out and it says 16256 is allocated.
Still not working.
Regarding the "enable 4g decoding" the bios doesn't feature that option, since it should be preconfigured for mining.
I still don't understand why three cards work when I plug in four, but only two cards work when I plug in three...
Strange thing.
