It's possible, but depending on your OS and processor it might be quite difficult. There are "Uncore" performance counters for this, but the means of access has been changing from generation to generation and the software sometimes lags behind. For Linux and Haswell EP, I've had luck with likwid: https://github.com/RRZE-HPC/likwid/wiki/Haswell-EP#memory-controller-fixed-purpose-counters https://github.com/RRZE-HPC/likwid/wiki/Haswell-EP#memory-co... You also might have luck with Andi Kleen's pmu-tools: https://github.com/andikleen/pmu-tools/blob/master/ucevent/README.md https://github.com/andikleen/pmu-tools/blob/master/ucevent/R... I don't know for sure if Intel's VTune supports these counters, but I'd presume it would: https://software.intel.com/en-us/intel-vtune-amplifier-xe https://software.intel.com/en-us/intel-vtune-amplifier-xe
