However, the price of memory has increased recently. In the early period, the memory of 4G was in the early stage of 100.

Common memories include Kingston, Wigan and Jinbang. However, the notes used in this book also include South Asia Yisheng and Samsung.

Theoretically, only 2G DDR3 1333 1 memory is needed, and the brand doesn't matter. Of course, it may also be incompatible with Mg 2G.

Personally, I think it's ok to change the memory of 4G directly, and the brand mentioned above is also ok.
