are these two modules interchangeable?

[Michael Butash]

I would highly recommend NOT mixing and matching sticks of ram, this has
never ended well for me, particularly since most everything is dual-channel
configs these days and really need to be paired exactly per bank.  If you
do/must, match them up as close as possible in terms of speed, cas/ras
latency, etc, or only use the exact same ram down to the model number.

I've long ago stopped mixing and matching sticks of ram for weird pc
crashes, I always put them in as a set now.  Matched sets by batch are
best, or if needing a bunch of sticks for a server, buying a batch of same
sticks used of ebay out of the same server has been good to me too, just
make sure to run a memtest on them first to make sure they're good if
used.

Likewise test if using off brand random sticks, they're probably cheap for
a reason ie. 2nd rate parts.  These days I only use samsung memory.
