RAM 16GB Upgrade Troubleshooting
I installed a 1TB SSD HB 2.5" and it worked like a charm. Then I installed the 16 GB RAM upgrade and nothing. No beeps, no chime, just a black screen and the fan might be running, hard to tell.
Back to the original 4 GB RAM and starts up like a charm. High Sierra and all else is up to date. Tried running the EFI updater available for my machine and got message that it's not supported by my system.
Took out one of the 2 GB sticks and put in one of the 8 GB sticks. Started right up and system info says it is running 10 GB RAM. Took that 8 out and put in other 8 and same result. Runs great. So the RAM I bought is not bad and my RAM slots both work, but it won't run with both 8 GB sticks.
Anyone encounter this too and if so is there a way to get all 16 GB of RAM to work?
