Xeon gang in the house. I picked up an HPE with an E5-2650 v4 on eBay with 64GB memory and some spinning disks for $180. Best investment I have made. It’s the z640 tower so pretty quiet and doesn’t need a rack. Core count has made my life a whole lot easier.
- My only complaint, when I doubled my ram from 128g to 256g of ddr4... it added another 100w of power usage. :-(
  
  Surely there's no way that's just the ram... did you also double your workload or something?
  
  A possible explanation is that the new ram sticks requires another memory channel to be active
  
  Every ddr4 ram module (8g of ram), uses around 3w. I have 256g of it.
  
  That is 32 modules * 3 = 96 watts.

  This is also ECC server ram, might be safe to say, it takes a bit more too.
