What is the maximum module size of DDR3 memory?

The maximum module size for DDR3 memory is 16 GB. DDR3 supports a maximum capacity of 8 GB per module for standard consumer memory, but through the use of double-sided (dual-rank) DIMMs, it is possible to configure modules up to 16 GB for a single memory slot in specific implementations. This allows systems to utilize higher memory capacities, particularly important in server environments and high-performance applications.

While the lower options such as 4 GB and 8 GB are indeed supported by DDR3 memory modules, they do not represent the upper limit of capacity. Option 32 GB exceeds the maximum supported size of DDR3 memory modules as defined by JEDEC standards. Hence, 16 GB is the correct answer, demonstrating the potential for enhanced memory capabilities in DDR3 technology.
