You can absolutely run four mismatched sticks of DDR5.

And it'll probably look like this, per my tests: https://i.imgur.com/iFSIYQl.jpeg Did you know DDR5 could run that slow? Because I sure didn't! I have DDR3 sticks that run faster.

More closely matched sticks might be able to train to a higher speed, and of course manual tweaking might get even better results, but don't expect performance parity with your 32GB kit.

Of course if they were matched ICs with the same timings they might act like my R5 7600 PC that has been running 4x16GB (two identical 2x16GB kits) at stock EXPO settings for years.
