I just found out why my electric bill has been so high, even though I keep trying to make my equipment more efficient.
Residential Customer: 19.45¢ per kWh
My son, one hour away pays less than half of that in Vancouver ! In the portland metro area, this is my rate !
Mark,
Long time lurker here from Canada. Sorry to hear about the
big rate increases in Portland. I've done quite a bit of research on
Folding Efficiency and
Folding during Time of Use Mid and Off-Peak periods.
My mission is to do the most amount of work for the least amount of non-renewable energy.
Might I suggest that you try Clock-Limiting your GPUs. The last test I did on a RTX 4080 Super showed that limiting the clocks on Ada to 2200MHz (nvidia-smi -i 0 -lgc 0,2205) can reduce power consumed by almost 40% with a reduction in Yield of less than 20%. Testing on Ampere and Turing showed the "Sweet-Spot" (peak Efficiency) to be a 1440MHz Clock Limit. The rule of thumb seems to be to limit the upper bound of the GPU or Shader Clock to the "Base" Clock for peak efficiency.
For your
Titan V's your limited to having to use Power Limits as Pascal and earlier don't support Clock-Limits. Setting the Power-Limit to the minimum supported Power (nvidia-smi -pm; then nvidia-smi -i 0 -pl 100) will usually be most efficient.
Having a Network Meter installed and changing from a Basic Plan to a Time of Use (ToU) plan and only folding during Off-Peak or Off and Mid-Peak periods can also substantially decrease Electricity bills. I was running my much more efficient Ada cards during Off-Peak and Mid-Peak Periods and my less efficient Ampere Cards only during Off-Peak periods.
Yes, It is a pain to setup but you can leverage Cron in Linux and Task Scheduler in Widows to do most of the heavy lifting for you.
