BSOD at random times - Mostly with chrome, revit, outlook open.

Both dumps are the same:

Code:

BugCheck EF, {ffff860625f10080, 0, 0, 0}

ETW minidump data unavailable
Probably caused by : memory_corruption

Nothing else in the dumps are of any use. I suggest testing your memory first. Looks like you have one 8GB module.
===================================================
RAM:

Follow this tutorial: MemTest86+ - Test RAM - Windows 10 Forums

   Information

MemTest86+ is a diagnostic tool designed to test Random Access Memory (RAM) for faults. MemTest86+ will verify that:

• RAM will accept and keep random patterns of data sent to it
• There are no errors when different parts of memory try to interact
• There are no conflicts between memory addresses

Memtest86+ runs from bootable media to isolate the RAM from the system, no other components are taken into account during the test.

   Warning

MemTest86+ needs to run for at least 8 passes to be anywhere near conclusive, anything less will not give a complete analysis of the RAM.

If you are asked to run MemTest86+ by a Ten Forums member make sure you run the full 8 passes for conclusive results. If you run less than 8 passes you will be asked to run it again.

   Note

MemTest86+ has been known to discover errors in RAM in later passes than the eighth pass. This is for information only; if you feel there is a definite problem with the RAM and 8 passes have shown no errors feel free to continue for longer.

Running 8 passes of MemTest86+ is a long and drawn out exercise and the more RAM you have the longer it will take. It's recommended to run MemTest86+ just before you go to bed and leave it overnight.

Nothing new in the latest dump, another memory_corruption.

I do see many of these in the eventlog.txt (Event Viewer)
