I want to set power limit to DRAM with using RAPL.
So I set "Enable bit" to "1" and "DRAM Power Limit" to "power limit I wanted to set" in MSR_DRAM_POWER_LIMIT register.
Then, I set Power limit of DRAM to "20W" and mesured power HPCC benchmarks with RAPL.
But the limit didn't work.
Need any other configuration?
I use Xeon E5-2680.
