Memory upgrade causing system to crash after a minute
[Edit: the system runs fine after having replaced the built-in SO-DIMMs with the ones from OWC - i.e., 2x16 GB, but I’d still like to know if they should be compatible to install both together]
I bought an iMac with 8 GB of memory, and separately 32 GB from OWC. I tried to install the two 16 GB sticks into the empty slots, and even though the computer booted fine, it went into a restart/crash loop after running for about 60 seconds. Before it crashed the first time, I saw the memory tab in “About mac” and it showed all 4 modules as correctly installed.
I’ve since removed the sticks and I’m currently only using the two built in 4 GB sticks in their original slots (never removed them) and the iMac boots and runs smoothly, but I’d preferably like to install the other two sticks too. What’s the best way to debug the issue? Should I try removing the original RAM and inserting the OWC RAM sticks into the same slots?
Thanks!
Is dit een goede vraag?

Try and run it with just the two sticks that you had bought to see if that could be the issue. It could just be defective ram chips

It's thankfully running fine with just the base 8 GB - sorry if it wasn't clear enough, I'll edit the question!
Edit: ah - sorry, I guess you meant to try out the two sticks I bought separately. I'll try that and see what happens.

It would be very unlikely that this could be the case but do you think there could be damage on the RAM slot pins? Try to shine a flashlight onto the sockets and see if there is damage or just go by trial and error and put the ram in slot by slots to see if they all work.

Where did you get the SODIMM's? And what did they sell you? Make and specs.

This is what it says on the invoice:
32.0GB (2x 16GB) PC4-21300 DDR4 2666MHz SO-DIMM 260 Pin Memory Upgrade Kit for 2019 iMac and 2018 Mac mini models and PCs which utilize PC4-21300 SO-DIMM. OWC Lifetime Advance Replacement Limited Warranty.
I'm going to try replacing the Apple memory sticks with these only, instead of using all 4 slots later today - haven't gotten around to it yet.
