New memory? Solve constant CTD

[Airsoft]

Get sporadic CTD from playing Arma 3 and wargame. Even got CTD playing wargame saying a memory issue. Will upgraded memory solve this?

Currently have this

Looking at this a good replacement? Will that improve my constant CTD?

Also plan on running 2 monitors and doing a lot of 3D CAD analysis if that's at all important.

Have you downloaded and run MemTest86+?

run memtest, id doesnt show anything, swap ram sticks with places, see how it goes, run memtest again.

Also, try running one stick at time to see which one is faulty. And as its Corsair - lifetime guarantee, use it.

Doing CAD - need GPU and RAM, so 16GB RAM upgrade should be good upgrade.
