Hi Adithya5,


Welcome to the Community Forums.


OEM recommended RAM for upgrade are listed here on the parts lookup along with the substitutes:


Part number 11201304 Mic MT16KTF1G64HZ-1G6E1 DDR3L 1600 8GB

Part number 11202082 M471B1G73DB0-YK0 25nm 8GB DDR3L 1600

Part number 11202450 RMT3160ME68FAF-1600 8GB DDR3L 1600

Part number 11202707 SK HMT41GS6BFR8A-PB 8GB DDR3L 1600

Part number 5M30G18424 M471B1G73EB0-YK0 1600 8GB


Listed RAM for 8GB also here in the hardware manual item 11 page 77.


Getting a non OEM RAM should also work ensuring it has the same specification and check for a good return policy just in case. 8GB + 4GB is also an acceptable combination for the model.


PC3-12800 1600MHz DDR3L (low voltage), dual-channel capable, two 204-pin SO-DIMM sockets 


Hope this help answer your query.
