Sure thing. If you’ve ever purchased Crucial memory, that’s their “consumer” brand, where they make the DIMMs themselves, so you’ll have some of their memory chips. There was a lot of outrage on here that they stopped doing that during the RAM shortage, prioritized filling B2B demand first.

There are also third-party DIMM manufacturers like PNY (also US-based) that make DIMMs with chips from memory chip manufacturers, and they might be using Micron memory chips as well.

If you’re on Linux, you can check what’s in your system at the DIMM level without pulling it open with:

$ sudo dmidecode -t memory

I don’t know if there’s a way to see where the chips on a third-party DIMM come from — like, potentially Micron, with a third-party manufacturer — without actually looking at the chip.
