Problem with Dell Optiplex RAM not functioning.
Problem with Dell Optiplex RAM not functioning.
Hi Alex, I see the issue. You're trying to upgrade your Dell OptiPlex 390 with 4 GB RAM, but you're getting errors when using a DDR3 Samsung stick. Make sure the RAM matches the specifications for that model—DDR3 is not compatible with the OptiPlex 390. Also, check the motherboard support and try a different RAM type if needed. Let me know if you need more help!
All the information I've found points to a compatibility problem. The discussions about upgrading memory focus solely on Crucial products. https://www.crucial.com/usa/en/compatibl...90-desktop
