Crypto rig part deux! (Mostly pics)

In the process of this ‘rebuild,’ one night I was trying to figure out different software settings and when I looked down, my CPU was idling at 98C degrees. After further inspection, I found the culprit. The heatsink has so much dust caked and cooked in the aluminum fins it was gross.

That project required me to pull the motherboard from the case, and disassemble the CPU mount and stock intel heatsink bracket. Somehow in the process i shorted 2 DIMM slots of memory. Oops. Its a 5 year old motherboard that need to be replaced anyway with a more “mining appropriate” board. Right now im using one of those PCIE riser cards that splits the PCIE into 2 different busses so you can use 2 different GPU’s. I know thats not the ‘correct’ or recommended way but it works for now. Here is the setup now mining ETH on nicehash.

She may not be pretty, but its still a work in progress.

Focusing on XMR(CryptoNight) since the payout rate is still crazy high at 343 BTC/GH:

Cryptocurrency mining, my experiment, and what could be the future

Edit: Check out part 2 for more pics

As some of you know, recently I have indulged in the world of blockchain and cryptocurrency. For those reading who don’t know what crypto is, think Bitcoin. If you have been living under a rock and haven’t heard of Bitcoin, check out the youtube video at the end of this blog post (don’t worry its short and to the point so you shouldn’t be too bored 🙃 ).

So in the most basic terms possible, its internet money. For years bitcoin hasn’t been profitable to mine unless you are a big “farm” with multiple rigs networked together to make a super-computer, or a ‘farm’ or ASIC miners (basically machines designed to mine bitcoin that tend to be expensive to purchase, and expensive to run). That all changed with the release of Ethereum, and how quickly it took off. It de-centralized the market (again, kind of) and brought mining power back to the home ‘user.’ Over the course of the last year, different algorithms have been used in blockchain technologies to create a new market of cryptocurrencies known as ‘alt-coins.’ This essentially launched the crypto market into a real economy. Its stability is a hot debate topic amongst the tope economists and technologists in the world.

Asleep yet?

So I decided to get involved. My funds are very limited, so this is a slow experiment for now. This is what I call Prototype phase 1:

This is an old gaming PC I built with my AT&T ‘fuck you’ money in 2012 when I quit. Specs:
– 3rd Generation Intel i5-2400
– ASRock z77 Extreme4 Mothboard
– (Started with) 12GB DDR3 (i think PC-3200 but i could be off) which became 8GB after i managed to short out 2 memory DIMM’s
– Thermaltake 730 watt PSU
– 4 PCI-E 16x to 4x power risers
– 3 ATI RX 570’s (2 MSI Armor’s, 1 XFX OC Gaming) (only 1 MSI and the XFX pictured above)
– EDIT: There was a 4th card, a GTX 1050ti i originally chose since it drew almost nothing for power, however the hashing power wasn’t worth what i paid, so i will be replacing it with a bigger ‘heavy-hitter’ soon

I have an old intel 120gb SSD for storage.

Its certainly not pretty, nor is it complete (need a new PSU and motherboard, along with my final GPU). It basically just a torn apart PC with wires all over the place.

Right now I’m mining on Nicehash using their algorithm switcher. Average daily profit:

Still have lot to fine tune and complete!

EDIT 2: Some asked what my hash rates per card are: (i can play with tuning and get better but this is average)
