Ram is not being detected, I made sure it was connected accurately and that it made the “snap” sound. I made sure to do the following steps:
inserted the gold connectors and the empty notch to the notch on the Synology
Using the Synology 4GB DDR4 2666 MHz Non-ECC SO-DIMM -
Rebooted Synology and ran Memory Check on Assistant
Control Panel > Hardware and Power > General. and unchecked the First checkbox.
What synology are you using? have you made sure it’s able to take more ram? have you checked synology’s ram compatability list to make sure the ram you bought works with your synology model?
from here you might need to start going through your hardware troubleshooting steps. If everything else is setup correctly: you may have either a bad ram stick or a bad motherboard ram slot.
I would start by removing the old ram stick from it’s current slot and replacing it with the new ram stick. Then at least you’ll know if the new ram stick works or not.
