I'm not sure what information I need to provide. I have a Trident 3 9sh-444us I attempted to upgrade this device from 8gb total memory to 16 gb total memory. I used DMS Data Memory Systems 16GB DDR4-2400 PC4-19200 2048x64 CL17 1.2V 260 Pin SODIMM . Now obviously I wasn't on relying on the websites claim that it was 100 percent compatible but it just leaves me wondering how I can upgrade my memory. I turned off the computer and removed all external plugs. Removed the old 8gb memory and inserted this 16gb module and the system wouldn't start. The led light turned on as if it was function in some form but no visual out put to my monitor. I returned the 8gb original module and it booted right up. I can't even enter safe mode with the new module. I seem stuck because I've seen people online say you can at least get 16 gb memory output but not sure what device to use.
