TDP is Thermal Design Power, it doesn't mean the max power. Whilst experimenting with my new desktop, with a 65W TDP CPU, the power of the whole system (measured at the mains supply) went from 16W idle to 170W by executing "while : ; do : ; done" for each core. I'd guess the bulk of that is the CPU, not the memory system. It soon drops to 130W as the thermal protection kicks in, but you'd want a PSU to cope with the peaks. And maxing out all cores isn't just a theoretical exercise, transcoding video files or compiling programs will happily do that. -- Tixy
