CPU cores are really single threaded, meaning they can compute 1 task at a time. CPUs these days are often offered in 2 or 4 cores, meaning they can simultaneously calculate 4 things at once. GPUs on the other hand have many cores, allowing them to calculate many different things simultaneously. The GPU I have has 3584 cores, meaning it can calculate 3584 things at the same time. They are way more power efficient for tasks optimized for this multi-threaded capability.

My GPU can generate about $100/mo in Bitcoin, and my insanely powerful 32 core CPU can generate about $10.

Lots I don't even fundamentally understand, like why a necessary component of establishing trust is presenting insanely compute intensive math problems, where "guesses" are made. I don't know any math that involves guessing. I don't know why that is a critical element to establishing trust, and I don't know how it can be known when a guess was correct since knowing the answer would defeat the purpose of the guess.

Like most things, I assume there exists a relatively simple high-level explanation, but nobody is forthcoming with it.

I'd have to review to take a crack at that, and it's sunny outside.

The part that amazes me is that you can pick any arbitrary 50-digit string and be assured it hasn't been taken simply by the Power of Big Numbers.

Well my attempt to migrate the Tesla P100 GPU into a tower seems to have been misguided. The GPU has no active cooling, meaning it depends on the airflow of the rig it's in, and therefore designed to be in a 2U server with plenty of noisy cooling fans. The OS was reporting a resource conflict (error 12) and I couldn't figure out how to clear it. Probably it isn't possible for that hardware. The hope was to cut 100 watts of server overhead and reduce noise to a level where it could live in my office instead of the boiler room in the basement.

New plan is to relocate the server to my parents who have more excess electricity production than me. I've made about $1000 mining since February and had to pay $60 in electricity since I couldn't quite produce everything I needed.

I'll build up that spare tower to be my surveillance PVR (BlueIris), media server (Plex), and 3 display gaming rig, though I'll hardly ever get a chance to game.

I may be a little behind, but it sounds like this is not a Tesla P100D OEM computer running off-label, but maybe something by Nvidia? Not the Dojo architecture? It looks the same here.

If you'd paid for all the power at the rate the $60 segment was, what would it have cost then?

You have the PCIe card? The [$200] reTerminal has a PCIe slot. I wonder if they would work together. If you follow Major Hardware on Youtube (www.youtube.com/c/MajorHardware), you could take one of his winning designs and then undervolt a few of them.

Stick it in a bucket of baby oil. Aquarium pumps are pretty quiet.

Yes, Nvidia P100. It wasn't clear to me that it had no fans. Also not sure if it can run in a normal tower workstation given the vague error I was getting about insufficient resources. These cards are finicky. There was a server that would detect the card but wouldn't enable it. Turns out it wanted a power connector from a specific spot from the server, and not an identical looking one that it was plugged into. The difficulty in figuring out that mystery is how I ended up with this "extra".

The server runs 500 watts when mining, and 250 watts at idle. If I didn't have excess solar generation, it would cost me $440 per year in electricity. That's nearly half of my "profit".

Maybe I'm trying to kill to many stones with 1 bird by combining a surveillance PVR, gaming rig, media server, and crypto miner all in one.

Furthermore, it also has a high-speed expansion interface with a PCIe 1-lane Host, Gen 2 (5Gbps), USB 2.0 port, 28 GPIOs, and PoE. You can use this interface for industrial and more advanced scenarios!
See what you think. With the Power over Ethernet and PCIe hosting it could potentially be a lid to your aquarium full of baby oil (Not made from real babies). 5V@4A DC, how much power does the Nvidia card draw?

edit: Currently on back order, but it includes a cryptography chip and accelerometer.

I'd be interested if I didn't get my hardware for free, and had time to learn something other than Windohs.

My quick and dirty solution is to move the mining to my parents house. They forfeited 1068 kWh in March during the 10 months they had solar. They did get a Nissan Leaf this year, so I better re-evaluate how much excess they actually have...

Just had the thought to put the miner in my grandmother's empty house. The heat is being run just to keep the place from decomposing, but I could at least put those 500w to useful work there.

I've already spent $68 on electricity since March (the true-up month) and we haven't even hit the cold and dark season yet.

That's smart.

The quickest option was to move my mining rig to my parents house. They have a cold spare bedroom, and I placed the server under the bed so it's out of sight. If someone wants to use the room, I can shut the server down (remotely).

It's quiet enough they can leave the door open and allow the heat to disperse through the house. I'm told the heat is making the heat pump run less often, and it's certainly a lot warmer in the room now.

It's taking about 100 days to mine 0.1 Ethereum. If the mining rate is cut any further (April), it probably isn't worth my time to mine even with free electricity. Wondering what other promising currencies can still be mined with GPUs?

I've got 0.35 Ethereum so far and was hoping to get to 1. Not gonna happen now it seems. I'll be lucky to hit 0.5

I haven't given up on the notion of moving the GPUs into the more efficient Tower PC I've got. Just need to solve how to cool the card, and I suspect the "This device cannot find enough free resources" error is due to improper power.
