Hello michaelking. Welcome to the forum.
My advice is to sent it back RMA. If it is early enough you may be able to do so before it ships.
The RAM speed is not that important. It will run at a lower speed just fine.
But the voltage will give you problems. Running 1.65v RAM at 1.5v will likely result in RAM errors. Running it at 1.65v can damage the processor.
Get the correct RAM.
