    Question Ryzen 1700 - Poor memory bandwidth?

    Hi all. I've been away from these forums for a long time, it's good to be back!

    Doing some benchmarks recently, I noticed that I'm getting much lower memory bandwidth results than other Ryzen systems ... about half

    My results:


    Comparison:


    I'm not new to overclocking, but something tells me I've goofed somewhere here ... I'm just not sure where. Please does anyone have any pointers?

    It's running in single channel. Look at the "Memory Type" in the Benchmark results, higher ones say Dual.

    I thought that only contributed around 5-10% though. Am I wrong there?

    EDIT: Ah, I'd got that wrong. Maybe 5-10% performance increase in some applications, but ~double the bandwidth. Knew it would be something daft! Thank you!
