Note: Dual channel is a technology that doubles the memory bandwidth
capability to transfer 128 bits using two 64-bit wide channels for the DDR
memory interface. A total 128-bit wide dual channel DDR memory interface is
achieved by loading identical pairs of two DDR memory modules with the
same speed and the same capacity.
Precautions when selecting memory modules.
• There are various types of memory modules. Make sure that the products
purchased at a store have a written warranty for the device when
installing.
• Sony does not provide support for memory modules purchased at stores.
Consult with the dealer where you purchased the memory module with
questions.
