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?
