Incompatible RAM? This PC uses 1600 MHz, DDR3L (Low voltage) RAM.
If that's what you bought, you can try clearing BIOS to see if it will recognize the new RAM:
And if it is DDR3L and clearing BIOS doesn't help, the RAM isn't compatible....

Hi All
I have been having the same problem of upgrading my Dell memory too, having tried all of the option posted and 3 different rams, said to work with my system, I thought let’s see if I can get one that matches the part numbers and other numbers that it was marked on the memory, by looking at pictures of the ones for sale. Got the nearest I could find, exact part number, exact type (not missing the L as this is important), same make, 4 digit and 10 digit number close. This worked for me and system booted as expected!
