It's been 2 weeks since I use these bars in a mobile-based APU amd 3420m. The latencies to 1333MHz (the maximum for my apu) are 8 and I won 15% memory bandwidth band. It is felt at the level of use in photo editing and a little in the few games I play on the PC, there is no difference to my other office automation and management software. The large capacity makes it possible to see it coming, especially for those like me who use many software at the same time (even with 10 windows of Mozilla Firefox, Word, Excel, Photoshop, plus access to a swap therefore more slowdowns file).
