    I plan to transition slowly to Ryzen 36XX boxes, Ryzen's use a lot less power to run.

    Absolutely the Ryzen 3000 series (3600 and upwards) are going to be your best bang for the buck. somewhere around 40h/w or higher if the benchmarks are valid. As I mention I am primarily running my servers for the heat generation in the basement as the weather get cold. I will more than likely turn them off come late spring.

    We also have about 150 OCP nodes with 2x2660v2 each, mining monero now. I've done some tests with dual-channel memory. HR was around 6000h/s, did't measure power though. Want to test it again later with proper quad channel memory and power measurements using DCMI interface

    I would hate to have that electricity bill on 150 nodes. I have six and have only test mined with them for a day or two at a time in the last year and a half.

    I have them in my dining room and at %100 they do put out some heat except with the 2603 v1's installed so during the summer they are mostly off to save on the electric bill.

    Testing the nodes, not the latest version of xmrig.

    Tried xmrig 4.0.1- beta on my Ryzen 3700x pc with a single RX580.

    The opencl mining did not work, I have AMD-GPU-Pro and legacy opencl installed and working.

    Version 3.1.3 mined a tiny bit faster than 4.0.1-beta with just the cpu cores.

    How does rx/loki hashrate translate to cn/r?

    That's really a apple vs orange comparison.

    Cpu's mine MUCH faster on randomx vs cn/r and gpu's mine probably about 2/3's of the rate on randomx.

    At first I thought that there would be a massive drop in the network hash rate because the gpu's would no longer be dominating or even competitive and they all would leave.

    Now I'm not so sure, there is so many factors involved that affects the network hash rate.

    I think at first there will be a huge drop just because of the change but that will probably swing back and get higher simply because everyone that mines has the hardware to mine with cpu's plus the bot nets i'm sure will be updated.

    Also quite a few will update their gpu rigs because thats what they have the most compute power invested in and i'm sure they will switch to the new algo and mine at least for a while just to see before they switch to another algo if it proves to be unprofitable for them.

    So this is my forcast:
    Short term a big drop in network hash rate.
    Long term will increase to probably halfway between the current hash rate and the peak when the asics were hashing on the network.

    UPDATE: Network upgrade no longer in mid October, now its November ~30th.

    From the reddit Monero page:

    Preliminary information thread regarding the scheduled protocol upgrade of November 30 : Monero

    "General information about the scheduled network upgrade
    Approximately the 30th of November there will be a scheduled network upgrade on the Monero network. To be sufficiently prepared, a user, service, merchant, pool operator, or exchange should run CLI v0.15 or GUI v0.15. The scheduled network upgrade introduces a few major changes. First and foremost, a new long-term Proof-of-Work algorithm, namely RandomX, will be introduced. Miners therefore ought to upgrade their mining software as well. Second, long payment IDs will be phased out in order to improve privacy and user experience as well as reduce support work for services and exchanges. Third, transactions will now require at least two outputs. Fourth, the ten block (approximately twenty minutes) lock time for incoming transactions will be enforced on the protocol level. Both these changes will improve privacy for the user as well as for the whole network.

    A few notes:

    What ram timings are best for RandomX? Reading that timing and latency can have a noticeable difference on hashing performance.

    ok, guys...maybe stupid question....I am trying to run randomx-benchmark on windows 10 64bit from PowerShell, nothing happens. I downloaded the compiled version (for windows) from GitHub its self.

    the folder I see only BENCHMARK.EXE....tried ./benchmark, ./benchmark.exe, .\benchmark, .\benchmark.exe....all of this with --help or -help....nothing happens....even tried PowerShell as admin....and I have dotNET version 4.7.2 on windows 10....any help??

    you need to pass some arguments to it. RTFM.

    RANDOMX BENCHMARKS FOR MONERO MINING!

    Look for your cpu or a similar cpu then look to the "Parm" to the right and you will see some examples of the command line arguments.
