iMac si blocca dopo aver aggiunto memoria extra, qualche idea del perché?

Il mio iMac del 2010 27 "ha appena ricevuto un aggiornamento della RAM: ho acquistato un kit RAM da 16 GB di Crucial su Amazon, la specifica soddisfa i requisiti di questo modello di iMac e ha delle ottime valutazioni.

Quindi adesso i posti di memoria sono due 2 GB di RAM originali + due di 8 GB di RAM Cruciale. Il sistema si avvia perfettamente, ma quando eseguo compiti pesanti o eseguo l'app di test della memoria di Rember, si blocca completamente. Ho allegato due foto che mostrano i sedili della RAM e la schermata di arresto anomalo.
