Although memory compatibility cannot be guaranteed 100%, it is generally OK.The building owner can safely purchase 4G DDR3 1333 for replacement.In order to avoid problems, it is better not to plug into asymmetric dual channels.In addition, the 32-bit system cannot recognize the 4G memory, so it is useless to plug into 5G without changing the system.
It is estimated that it is OK!The motherboard of the G41 supports a maximum of 4g of ddr3 memory, which can be described as a single 4g---------It is not sure that a single 4g can be supported. It is recommended that the ddr3 of two 2g can be used directly, and the memory dual channel mode can be set.
