The computer I use is home built from a time that games where more a priority than photo editing.
Back then I did some photo editing, but my camera was an Olympus 16MP micro four thirds camera.
Now my software (Luminar 3) is crashing frequently. This happens mostly when removing dust or exporting.
According to my tastmanager my RAM at those times is at 100% use.

My hardware:
Processor: Intel Core i7-6700K
MB chipset: Z170
Video: GeForce GTX 1070
RAM: 16GB (2x8GB module) | DDR4 | 3,2GHz | CAS Latency 16 | True latency 10,0ns

Scanning:
Black and white 4x5 on an Epson V800, 2400DPi, Tiff

What would be a good upgrade?
I have room for 4x DDR4 RAM module

Does anyone else have chashing problems with big files and Luminar 3?
