    When I posted previously I had forgotten that you had already added a second DIMM to each system, ie I had been thinking that your CPUs were running with only one of four memory channels populated. Didn't expect the extra memory to make a difference but I as thinking that improving CPU memory bandwidth would make the CPU portions of the work run faster and improve your overall performance a bit.
    i had only 3 dimms of 16gb ddr4 mempory so the 1920 runs with 2 dimms and the 1900X runs with only 1 dimm.
    but both system make the same ethereum output... so more ram dimms do not make a difference. i can show you 24hour statistic about this.
    so in fact i can prove that going from 1 to 2 dimms gives you nearly zero more ethereum...

    right now the 8core with only 1 dimm is faster than the 12core with 2 dimms:

    24hour test run average 12 cores 2 dimms: 83.6 MH/s
    24hour test run average 8cores 1 dimm: 84.9 MH/s

      OK, good to know.

      On the 1920 do you have one DIMM connected to each of the active dies ? I'm sure you do, just checking...

        I do have an awesome 310€ money output per month thanks to the 17.40 driver.
        Heh, all this bullshit for like 200 euros per month (factoring in power costs), or 300 euros per month after a significant investment in solar panels and accompanying equipment.

        And it isn't even stable, rates may change at any time.

          but i can tell you the result right out of my mind from sources i know...

          on windows there is a mining only driver with the old closed source openCL stack
          with this driver a Vega-64 makes 43MH/s on the linux 17.40 mining driver the same card only make ~33MH/s

          for me the closed source version is not a option because i want to support opensource.

          But I am 100% sure the Open-Source will win the mining battle in the end. But it takes 2-3 more month.
          Thank you! Keep up the good work, I think this articles are extremely important!

            Aren't Carrizo and Kaveri (I have the latter) supported as well, hence CI?

              Why is Monero valuable? Why should I mine it over Gridcoin?

                Yeah I was curious, was this a old-style-pro-opencl or ROC-OpenCL driver? The release notes don't mention anything about ROC...

                  I did strictly follow the handbook of the mainboard. if this means the second dimm goes to the second active die then yes.

                    Gridcoin is fine?.... i only use monero to increase the total money output because ethereum on the CPU is pointless.

                    https://en.wikipedia.org/wiki/Gridcoin sounds very good. so whats your problem?

                      Can some1 explain?"And the six AMD Radeon RX VEGA 64 with the newest AMDGPU-PRO 17.40 Mining Beta driver jump from average ~33Mh/s to 180 MH/s in a twenty-four hour test run."
