Re:  However, both of them didn't work. Can anyone know the reason why? I noticed that both of your kits are with XMP profiles.  Normal timings would have better chance with compatibility.  Dell's RAM is guarantee to work, it also comes with warranty and support, although the pricings is considerably overpriced. Alternatively, some users (not all) have successfully upgraded with Crucial 's RAM, or ATech, just make sure that sellers offer free support and accepting return. While awaiting for information from Dell, if you prefer matching OEM ram, you may try SK Hynix HMCG78MEBSA092N, or HMCG78MEBSA095N.
Hello,I bought two kits ram 64Gb to upgrade the Optiplex machine. However, both of them didn't work. Can anyone know the reason why?First kit: GSKILL F5-4800S3838A32GX2-RS - [URL] Second kit: Kingston: KF548S38IBK2-64- [URL] As I checked, the bus and the type of ram are same as the one that is included in the machine (SK Hynix) Thank you a lot!
