Calculating DRAM bandwidth from EMON

[cnsujeer]

I wanted to extract DRAM bandwidth information from EMON. For the same I extracted the following events: 

• UNC_M_CAS_COUNT_RD
• UNC_M_CAS_COUNT_WR

And, then I used the below formula : 
DRAM Bandwidth in GBps = (UNC_M_CAS_COUNT_RD + UNC_M_CAS_COUNT_WR) * 64 / 1GB / Time (sample window) 

Is the above formula correct ? Especially using sampling duration as time ? 

The reason I am asking is, Vtune shows for an application high bandwidth. But, if I run the same application through EMON and use the above formula.. I get very less bandwidth. (~8 times less). So, I was doubting if the formula being used is correct ?

I'm following up with the developers on your question, and will have an answer shortly.

Any update on this?
