AMD's A-Series Kaveri APUs apparently works much better with a dual-rank memory modules as well as has a decent performance improvement when paired up with DDR3-2400 memory, according to a report from Computerbase.de.

The best bandwidth is apparently achieved when Kaveri APU has both memory channels populated by 2-rank memory modules or with four single-rank modules, depending on what you can get your hands on. The easiest, but not always precise, way to determine if the module is actually dual-rank, is to check if both sides of the module actually has DRAM chips. Of course, the best way is to use some software with memory details, like for example AIDA64, as there are some modules which are dual-rank but only one side of the PCB has DRAM chips.

According to the same report, AMD A-Series Kaveri APUs also benefit highly from DDR3-2400 and according to results, you could be looking at up to 15.2 percent performance increase when compared to DDR3-1866 memory modules.
