Unfortunately, most hardware vendors have decided not to expose these counters. You might want to file a request with your hardwarevendor to provide a BIOS that enables this feature or implements a BIOS option to enable it.

Cannot measure DRAM power
Hello Intel community, I have some questions about monitoring. I am using E5-2670 CPU, and Intel Server Board S2600CP. I heard that this platform can measure power consumption on CPU and DRAM respectivly, but there are a few errors. ------------------------------------------------------------------------------------------------------------- ERROR: QPI LL counter programming seems not to work. Q_P0_PCI_PMON_BOX_CTL=0xffffffff Please see BIOS options to enable the export of performance monitoring devices. ... S0; Consumed energy units: 1163926; Consumed Joules: 17.76; Watts: 17.80; Thermal headroom below TjMax: 65 S0; Consumed DRAM energy units: 0; Consumed DRAM Joules: 0.00; DRAM Watts: 0.00
-------------------------------------------------------------------------------------------------------------
First, I can't find that options in BIOS. What do I do? And secondly, although I run memory benchmark, DRAM energy are not measured like above. What's the problem? Hope this helps. Chanho Choi
