Before buying 8GB DDR3 memory, make sure your notebook can use 8GB DDR3 memory in a separate slot

Because the maximum memory capacity of some buyers' notebooks recently is DDR3 8GB, but there are two slots, so each slot supports up to DDR3 4GB.

For example: HM55 is not compatible with 8G memory and 4G 1600MHZ.Be sure to check before you buy.

DDR3 is also sold. But DDR3l memory is sent by default. If you need DDR3 memory. Please contact us before placing an order.
