CPU Load and Memory Bound Diagrams

I am trying to speedup my program via parallelization. I am unable to get speedup factor more than 3 on 8-cores Core i7 CPU.
I suspect I am facing DRAM access bottleneck.
Concurrency Analysis provides very good diagram of CPU load for each  thread over time,
​Is it possible to show access memory metrics (L1, L2, L3 Bound, DRAM Bound) on this diagram?
