Hi I'd like to add 8gb ram to my  standard 4gb ram, if i install 8gb ddr4 ram 3200mhz to my device that support 2133mhz would that cause any problem?

Hi Semo9134,

According to the hardware maintenance manual page 27 of Ideapad 320-15IKB, the specifications of the machine are as follows:

Installing a RAM with a higher speed than your device supports will not cause any problems.

The ram with 3200MHz will just automatically clockdown to what is set by your machine. The RAM will simply operate at the maximum speed that your device can handle, which in this case is 2133MHz.

So, you can go ahead and install the 8GB DDR4 RAM 3200MHz to your Lenovo Ideapad 320-15IKB.

You have to keep in mind that a ram with 3200MHz frequency is going to be expensive.

You can check the Parts Look Up site for some OEM compatible ram.
