Hmm, could cram another couple of 1080TIs into my dual boot Upsides: probably an extra $10/day, would pay for themselves by summer Downsides: might overload my circuit, probably requires a new power supply hm

Rearranged things a bit more, jammed one of my 1080s into the mATX rig I was using as NAS. Probably consumes ~300W full tilt, which is more than my refrigerator. Wiferobot is going to want to store perishables, so I'm renting space for it in my DM's house at $25/mo + electricity

Semi-final setup. Consumer rig, workstation, converted NAS. Calibrating now. Worried about toasting my 20A circuit and also about heat dissipation and finally about long-term fan noise irritating my cat, so workstation cards likely to be throttled Bonus: catpic.twitter.com/w7b8KE2Rxi

realized I could jam another card in my consumer rig, prices have increased about 40% since I bought a couple weeks ago maybe the real play is day trading 1080s, fellas

wowza. newegg just put up some new 1080ti ftw3 on sale for $800, and they sold out in <20m

Good news, everyone! My (single) breaker tripped today during lunch and won't reset Landlord: "Do computers use a lot of power?" oh boy

Now digging around my apartment with my landlord trying to track down (i) the source of the electrical short in my unit and (ii) the source of a strange smell something like Trail's End popcorn Hoping they are not the same thing

Landlord: do you actually want to try that? Electrician: fuck yeah, we're just having fun, right?

Ok SO Apparently, issue was a shorted jank-ass wire off the main circuit, probably installed 50y ago. Supplied power to outlets on a post near my breakfast bar. The outlets had 3 prongs but were not actually grounded This was the spot I had all my boxes plugged in, ofc

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

Quick check reveals probably not vermiculite Also it was burning which seems like a contraindication

Apartment rewired today, still stuck on 20A. Landlord bought me a bottle of cheap whiskey for my troubles, though he also helped himself to a few shots of my tequilapic.twitter.com/Jkie2OgBqC

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

I wish the government would just fucking rob me directly instead of forcing me to keep meticulous records of the size and associated fees and contemporaneous USD value of BTC for every fucking daily payout

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.
