DRAMClocks

[AnaKhorguani29]

Hello, I am running ./pcm-power.x for power usage evaluation. I got a bit confused about DRAMClocks. Does it represent DRAM memory frequency in Hz?

Given a Configured Memory Speed - 2666 MT/s, should the expected result be around 1333,000,000? (Half because of Double Data Rate thing)

Thank you in advance.

yes, correct, the number should be the half

Thank you very much for the confirmation.

I tested on two different machines, and I got the expected result on one of them. But on the other machine I got way lower DRAMClocks, which additionally fluctuated a lot. And since I read that DRAM frequency does not change dynamically, I was unsure that I understood this counter correctly.

Thanks again for such a quick reply.
