user validated 16GB crucial ram for 8930 Re: On marketplace near me there is… CT16G4DFD8266. The above memory 2x16 gb (Crucial CT16G4DFD8266.M16FR 2x16GB) is validated in 8930. [URL]
Hi I'm looking to upgrade my RAM with Crucial memory sticks. According to official site ([URL] I have to buy Crutial 16GB DDR4-2666UDIMM  CT16G4FRA266. On marketplace near me there is almost the same Crutial 16GB DDR4-2666UDIMM  but CT16G4DFD8266. Because I don't undestand the difference between this letters in bold  FRA and  DFD8, my question is may I buy this RAM or not. Any help is welcome Thanks!
