Evidence of mining capacity expansion: AMZN is out of stock on high-end PSUs. Had to debase myself with a Corsair and pay for rush on Newegg. Earlier, ended up getting another 1080ti, figured out I can cram 3x1080 in my consumer rig and 3x1080ti in my workstation.

Okay. Pulling in about $8/day in XMR with CPUs, $17.50 in BTC from
@NiceHashMining with 3x1080 and 1x1080ti. The 1080ti hashrate is double any one 1080 (!!!). Stacking 3 gpus in my workstation is getting a little toasty (85c even with a box fan), SO . . .2 replies 1 retweet 4 likesShow this thread -
. . . in the interest of learning and also because I realized the case (Mercury S8) can be converted to a GPU rack with a little modification, I'm going to grab some risers and see if I can extend my GPU working life by spacing them out. Pics to follow when set up.

Came home, house was 71F. Mission accomplished. Unfortunately, also dug around downstairs and saw thispic.twitter.com/ml3Wl4g8Av

So: two circuits serving the apartment, one for hardwired lights, one for everything else. Hmmm. Guess I could take down a chandelier and rewire it to an outlet. Or just make use of an existing set of wires from the ceilingpic.twitter.com/4SFDA5dHk6

Before I do that, though, going to flip the breaker and see what still works outlet-wise. My guess is nothing but gotta be sure.

Interesting. Flipping the switch disables lights *and* outlets. Possibilities: 1. Single circuit, 20A 2. One breaker switch controls two 10A circuits First possibility would be the most convenient. Unsure how to test. Need to read up on breaker notation next I think.

Helpful mutuals assure me (1) it's a single fixed 20A circuit and (2) fucking with the circuit breaker will result in literal face melting, so spent the evening playing with GPU optimization. Heat actually a major bottleneck when 3 GPUs arrayed with no space, surprising no one.

So, working around this. Earlier plan for 16x -> 1x risers for my case won't work since *all* the slots in my board are x8/x16 form factor. Instead, repurposing my pseudo-NAS box to hold one 1080, and going to kludge a different solution with a ribbon riser in my workstation.

going to try a box fan and see how it goes. I'm down by about 15C from where I was, so I think I can handle ambient temperatures 10F higher without tooooo much loss
