SK Hynix memories for Vostro 7620

Hello.

Need help for memory upgrade (from 8 Gb to 16 Gb, in Vostro 7620). I see that there're two SK Hynix memories (16 Gb) that should be compatible with Vostro 7620: HMCG78MEBSA092N and HMCG78AEBSA095N. Are they really compatible? Which one would be the best for this laptop, and why?

Thanks.
