Question Maximume RAM for Dell vostro 3500 Core i5

Jul 26, 2021
I have the following Dell Vostro 3500 laptop which currently have 4 GB of RAM:-

Dell Vostro 3500 NEW Intel 11th Gen Core i5 Business Laptop
Dell New Vostro 3500 Intel Core i5 11Gen up to 4.2Ghz 4-Cores 8M Cash, 4GB DDR4 RAM , Optional SSD + 1TB HDD , Intel® Iris® Xe Graphics ,15.6" Full HD Display , Camera , Wireless , Bluetooth , Free Dos.

so can we upgrade the RAM by adding 16 GB on one slot and 4 GB on the other slot so we will end up having 20 GB of RAM? or the laptop have a maximum RAM size?
