Hi I have the specs as depicted below. Noob here, not sure what is relevant, feel free to explain in baby steps at me

I want to replace the non-fixed RAM slot with 8GB or 16GB (pretty sure it has 4GB soldered). Will these do the job?
Crucial 16GB DDR4 2400 SODIMM 1.2V (1x16GB) - Umart.com.auCrucial 8GB DDR4 2400 MT/s (PC4-19200) CL17 SR x8 Unbuffered SODIMM 260pin Single Ranked - Umart.com.auHave seen in other responses that Aspire 5 A515-51 needs CL= 15 (albeit in a 2133MHz context, maybe a diff model?)), whereas these are CL=17, and I seem to be 2400 MHz. I can't see the relevant CL value in my specs. Or is that the RAS# [etc] figure in the CPU-Z test? (slot #2 read as blank).
THANKS in advance.
