I run an Intel(R) Xeon(R) CPU E5520 @ 2.27GHz and follow, apart from perf list, this list <http://oprofile.sourceforge.net/docs/intel-corei7-events.php>for the available counters. Based on Linux perf events Event Sources <http://www.brendangregg.com/perf.html> I expected that counters like MEM_STORE_RETIRED and MEM_LOAD_RETIRED would capture only DRAM's activity. I mean that if I don't use DRAM it's bizarre to me to see these counters have the same trend with CPI and other cpu counters. I run a cpu intensive benchmark which does not use DRAM, as I could see from htop, and these two counters followed the same trend, in the graph that I created later, with almost all the other counters. So, my question is if there are any counters which are "triggered" only when I use DRAM? Like the IO_TRANSACTIONS which is triggered only when I have I/Os.
