Hello, I have a thinkpad X240 with Ddr3 4gb RAM 800mhz, I recently tried to change the ram for Ddr3 8gb 1600mhz (I saw many people upgrading with this specs so I thought its OK), but after I turn on the laptop with the new RAM, the bios beeps 3-3-1 and I don't know what it means. It's like:
beep beep beep beep beep beep beeeeeeep
What does it means and how can I make the upgrade work?
