    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.

    HP DL360 Gen8 2x2660v2 (Static High Performance, Max Performance), 128Gb RAM, Quad-channel (4*16GB DIMM each CPU)

    Oracle Linux 7.7 4.14.35-1902.4.8.el7uek.x86_64

    Keep in mind that this benchmark is not NUMA-friendly

    Code:

    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

    Just got my R710 back online. Running the 1.10 version of the randomx benchmark I am getting arond 2431 h/s.

    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.
