Hi there,
I would hope so but I can't be sure as the notes given for the Updates don't mention Memory but an update to the CPU code is mentioned and this could resolve the problem.
If you do flash BIOS you can always Flash back to your present one in the same way so you don't need to worry about that. But, when you update BIOS any of your current BIOS changes will be lost and you will have to redo them again.
