> PSA: motherboards these days have a RAM compatibility list on their product page, check it before overspending on RAM.
That's a valuable PSA, but FYI it's been that way since the 80s. I've been bitten by compatibility issues at least once a decade since the 90s myself, and the answer from forums or support is always "did you check the compatibility table tho?".
Some memory manufacturers have lists of motherboards compatible with a given memory kit. E.g. I checked that my motherboard was listed in [1] before buying the memory, and everything worked effortlessly together with EXPO on.
