Thinkpad X240 RAM Upgrade Help

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?

That means that there is an issue with your memory (RAM) either the RAM you got for it is not compatible or it's just not liking it.Annotation 2019-07-10 145310.jpg
