Yes, sorry for not being more explicit! It's 3x8GiB. Originally 4x, but one of my RAM sticks broke and I never bothered to replace it.

I'm not deep into the details of the AMD DRAM controller, but this detail could cause some of your anomalies. If this was an academic paper, the findings would be borderline invalid. You might want to remove the extra module and run the benchmarks again.

At least once the tests become big enough to have some data in both partitions, the bandwidth will start to matter.

    Thanks, I may try that.

    Out of curiosity, what do you see when running the same code on your machine?

      I can't run it right now: My AM4 desktop has a broken Linux dual boot since some Microsoft update seems to have nuked something important a few months ago, and my pure Linux Intel machine sits at 1.2 load with services I can't stop.

      If I get around to fixing my dual boot machine, I'll try to remember running the benchmark and dropping you some results by mail.
