      Going to be a little more deliberate about electricity use going forward. Having one of these things delivered tomorrow for GPU power calibration, til then going to leave the workstation off https://www.amazon.com/gp/product/B00009MDBU/ … Also so my landlord doesn't see a box with a GPU running on top

      bit of quick computation 20A maximum instantaneous load is 2400W; maximum continuous load, 1920W turns out a continuous load runs >= *3 hours* this is actually great news for me, refrigerator turns on only intermittently and probably draws substantially less than 480W

      Got my Watt meter, going to do some testing. Also installed a 1080 on a Rosewill 1x riser. Mobo recognizes the card, but not showing up in Windows . . . going to try driver reinstallation. Rig pulls about 120W mostly idle, incidentallypic.twitter.com/Z2dwHAhnPI

      That did it! Ordering some Thai while it benches for nicehash. Then, onto power testing. Goal will probably be to maximize power use by cards, conditional on total power use <= M M tbd, will mostly be a function of observed refrigerator and monitor draw.

      Early findings: (i) i7-5820k @ 3.8GHz draws only an extra 30W when full-tilt running CryptoNight (350H/s), that's awesome (ii) running a 1080TI FTW3 @ 100% pulls an extra 269W, about spec. Every 10% reduction in power target reduces draw by about 30W. Will test performace drop.

      Fascinating. 1080TIs seem to see 1:1 gains in hash rates as power increases until about 80% TDP, when the return drops off dramatically 1080s drop off dramatically at . . . 65% TDP? Less? Interesting implications for power use optimization anyway

      Ok. Final tally, for 4x1080TI @ 80%, 3 x 1080 @ 70%, 35 CPU cores >= 3GHz is . . . 1779 Watts Comfortably under my 1920W continuous limit although a bit dull numerologically main remaining concern is the fridge. rated 6.5A full-load, which would be (eep) 780W, insta-game over

          GOTCHA 160W, pathetic. Can't believe I was worried about that damn food hole Modem (<7W) + router (<8W) basically negligible, as is Penny's Litter Robot (<4W rotating). Monitor + speakers + usb dock are 70W together tho, gotta watch that

          Okay, off to catch up @ work but I think I'm set. Last task: replace one more 1080 on top of my workstation after a guy comes in to finish fixing the ceiling tomorrow Overall have say, the fire what burned through my ceiling was a small, basically-insignificant bump in the road

          Hmm. Evaluating "include the fair market value of the virtual currency, measured in U.S. dollars, as of the date that the virtual currency was received." Wonder if I can defend use of the daily low price.

          Do I need to pay self-employment taxes if I already max out SS/Medicare tax at my day job? Does wiferobot's rental duplex fuck things up further? What about quarterly estimated taxes? Join me as I investigate these and other exciting issues and slip deeper into anarchocapitalism

          what's the easiest way to sell used GPUs? AMZN, EBAY? Still have all the original packaging and plastic bits and such as I'm still turning a profit but it's 70 Fahrenheit in Seattle and @tradwiferobot wants to be able to use the oven without logging in and killing my workers

          Well, end of a fun era. I listed four of my GPUs on eBay and set another two up with some tweeps. If I hit the going eBay rate, even after they take their 10% cut I should be in the black on capital, so that's nice.

          Have bids on 3 cards already, from a Russian. I panicked for a second at the thought of paying to ship across the Pacific, but fortunately eBay restricts to domestic addresses by default. Hmm. If I'd been more thoughtful + had higher n, could've run some experiments . . .

          All right. Six cards sold, roughly for what I paid for them (or at a slight profit adjusting for the fact that I sold my old 1080 and kept one of the 1080Ti FTW). Still mining Monero with my E5 2687W-v4 chips, but I might cut back on that once it really warms up. Full circle!

          Overall, I think I made about $1500 net of electricity. Purely as a function of the hours I burned on this project, this was an economic loss given my marginal value of time. But factor in the value of learning, experimentation, heating, and entertainment, and I made a killing.

          Thanks for following along, everyone. I'll be sure to document the next slightly-unhinged project I start out on. (This wasn't my first--ask my pal @Lexirad about living with me sophomore year--and it sure won't be the last.) xoxo
