Two memories with varying delays may cause instability rather than just minor slowdowns.
Two memories with varying delays may cause instability rather than just minor slowdowns.
I'm sharing what you've got so your dad can understand. The laptop runs DDR4 with a top speed of 2400Hz, which is fine for everyday tasks. It has an onboard memory slot that uses slower access times (15-15-15-35), and the one you found was a CL17 module. Whether it will work depends on your needs—if you're okay with slightly reduced performance, it should function, but expect some lag or delays. If you notice frequent crashes, it might be due to the memory interface limitations rather than instability.
