Hi everyone. I'm having issues upgrading the ram of my laptop, it's a Dell Latitude 5400. It currently has 16 GB of ram, I recently installed 2 modules of 16 GB each to reach the max of 32 GB, accepted according to laptop specs.

However I have a problem, after upgrading it, the laptop doesn't start and led indicators blink 2 amber and 3 white, according to dell it is a display issue. If I reinstall the old modules all works correctly again.

Now, when I install an old memory in slot 1 and a new memory in slot 2 it works, I tried it with both new modules, but if I install a new module in slot 1 and an old one in slot 2 it fails with the same code.

Any clue?

Thanks!
