Undoubtedly, things have changed. Instead of weeding through hardware components, prospective miners must now sift through endless forums of pre-orders and group buys. I decommissioned my GPU farm in late 2012 since difficulty was rising and my GPUs still had a strong resale value. After waiting three months, I was hungry to start generating Bitcoins again.
With a big grin on my face I unboxed each unit. All units were packaged extremely well and arrived in great condition. As I unloaded these monsters into a vacant room in my house, I plugged them in and flipped them on. It was about this time I started realizing that ASIC mining was going to be trickier than I imagined.
The set-up was fairly straightforward thanks to many contributing members of the forums for advice on troubleshooting and setup. After about a half-hour with my partner we were ready to start mining!
The first unit switched on without a problem and we began mining away, but when we switched on the second unit, it flipped the breaker. This was a fairly modern house, however each breaker housed only one 10-amp circuit. At 6-7 amps per unit, my vacant room quickly turned into labyrinth with extension cords running all over my house, which I was fairly okay with.
Each unit had started hashing within +/-15% of its expected output. However, after a few hours I began to notice I was sitting in an oven. Each mining unit was putting out a significant amount of heat and units started hashing almost half of their original output.
After trying various methods to decrease ambient temperature, I gave in and bought a 12,000BTU 1-ton personal A/C unit to cool the room for around $600.00. This A/C alone was not able to handle 3 Avalons in spare bedroom during summer, and although my units were clocking around 55GH/s, I was underwhelmed by their unsteady performance.
In Seattle I live with mild temperatures and competitive electricity rates, so when I was having to further invest in A/C to cool my units, and pay hundreds of dollars in electricity per month ($0.12kWh), I figured there must be miners out there struggling to maximize the potential of their units.
This gave my partner and I the idea to start a Bitcoin ASIC specific co-location / hosting data center for Bitcoin miners. It all started to come together with the knowledge that electricity in Central Washington is some of the cheapest in the world at ~$.02kWh. After numerous trips to scout for a suitable property we found one in a secured location.
Our two goals: reach the full potential of every unit under our management and to operate at the lowest cost possible. At Bitcoin ASIC Hosting (www.bitcoinasichosting.com), we have achieved these goals.
Our facility is built completely with 3-phase power to handle any new hardware.
And adequate cooling to keep the ambient temperature of our facility in the mid 70s.
The performance increase in our hardware has been drastic. We also have experience overclocking and doing hardware upgrades to several types of units.
Avalon Batch #2 units (3 module):
Facility: 85 GH/s (peak at 88)
Avalon Batch #3 units (4 module):
Home: 75 GH/s
Facility: 110GH/s (peak at 115)
We are currently have several terrahashes under management and more demand is picking up. This all boils down to the fact that there has to be many GH, if not TH of unused potential. Many of these units run in a residential setting are being underutilized. At www.bitcoinasichosting.com, all units managed will reach maximum hash-rate and give you peace-of-mind during the mining process.
Operating fee is a factor of electricity and cooling requirements unique to each unit. By increasing the hash-rate of every device, we will increase your profits there will be no hashing lost due sub-optimal environments.
