RAM can be faulty straight out of the box.
Diagnostic tests aren't 100% accurate.
The only 100% accurate test is to replace the suspected stick(s) with stick(s) that are known to be good. Another option is to test those sticks in another system (if you have one).
Were you able to boot to Safe Mode? Can you conduct the tests there?
If able to, have you completed the Prime95 test that I suggested? How about the rest of the tests?
Have you tried testing each stick individually? This'll help to identify which stick(s) may have a problem.
Have you tried testing a good stick in each of the slots? This'll help rule out problems with the slots or the motherboard.
Here's my procedure for ruling out hardware problems:
My suggested way to diagnose a hardware problem (3 steps):
Step #1) Please run these free hardware diagnostics: http://www.carrona.org/hwdiag.html
Please run ALL of the tests and let us know the results.
If you can't run all the tests, then at least run these free, bootable diagnostics: http://www.carrona.org/initdiag.html
Step #2) If all the tests pass, then try to perform a clean install of Windows:
A clean install is:
- Windows is installed to a freshly partitioned hard drive with legitimate installation media (W10: https://www.microsoft.com/en-us/software-download/windows10 ).
- The installation media is only a copy of Windows, not the OEM recovery disks that you can make on some systems.
- Windows is fully updated after it's installed. That's ALL updates - none excepted.
- NO 3rd party software is installed.
- There are no errors in Device Manager (if you find any, post back for suggestions).
- The BIOS/UEFI is updated to the latest available version (this presumes that the system is compatible w/Windows 10 also).
This will wipe everything off of the computer, so it's advisable to backup your stuff first.
Also, it will wipe out all the special software that the OEM added to the system, so if you rely on any of that - let us know what it is so we can figure out a way to save/download it (the easiest way is to create/obtain the OEM;s recovery media)
If unable to find recovery media that has the software (or if you suspect that this is a hardware problem), you can make an image of your system that'll preserve everything in the state that it was in when you made the image. You can also do this if you don't want to try another hard drive - yet you want to be able to return to the current system state.
One drawback to this is that you're making an image of a malfunctioning system - so, if there are errors in the system software, you'll have a nice copy of them 
Another drawback is that the image of the system will be very large - so you'll most likely need a large external drive to store it on.
But, this will allow you to save everything on the hard drive (although you'll need an image viewer to get things out of the image).
The point here is that, if it's a hardware problem, then you can restore the system to the point it was when you made the image - after you repair the hardware problem.
You can obtain more info on imaging in the Backup/Imaging/DiskMgmt forums located here: http://www.bleepingcomputer.com/forums/f/238/backup-imaging-and-disk-management-software/
The point of doing this (the clean install) is to:
- rule out Windows as a problem (if the problem continues, it's not a Windows problem as you completely replaced Windows
- rule out 3rd party software (if the problem continues, it's not a 3rd party software problem as you didn't install any 3rd party software)
- so, if the problem continues, it must be a hardware problem.
OTOH, if the problem stops, then it was either a Windows or 3rd party software problem. If the problem doesn't come back, then you've fixed it. Then all that remains is setting the computer back up the way that you'd like it and importing your data from the backup you made.
Step #3) Then, if the clean install confirms the hardware problem, try this procedure to isolate the problem device(s): http://www.carrona.org/strpdown.html
