Hello AAlf01
According to the specs on https://support.hp.com/de-de..., this should work without any problems. RAMs designed for faster timings usually work as well, so they can also be operated "more slowly". If I were you, I would take the risk of buying it, because in my experience it has practically always worked in comparable cases. However, I would first take a close look at the RAMs already installed.
Greetings, T.
