I have an HP Probook 450 G5 laptop. It uses a Hynix 8GB memory module with the description SK Hynix 8GB DDR4 1Rx8 PC4-2400T SA1-11 HMA81GS6AFR8N.
I would like to upgrade the memory to 16 GB. The corresponding 16 GB memory module seems to use the spec SE1-11 instead of SA1-11. Otherwise the specs are very similar (16GB DDR4 2Rx8 PC4-2400T SE1-11).
I would be most grateful if anyone could help me with the following questions:
What is the meaning of the SA1-11 versus the SE1-11?
Would this 16GB module be compatible with the HP Probook 450 G5?
Would I be able to use the 16 GB module alongside the 8 GB module?
Thank you for your assistance!
