Bitmain Antminer S5

The AntMiner S5 Still Relevant to Modern Mining?

Bitmain released their AntMiner S5 Bitcoin miner in late 2014. At that time, it was one of the fastest and most efficient ASIC miners available, rivalled by the Spondoolies-Tech SP20.

However, the S5 has long since been surpassed by newer models.

As a product of a 28nm fabrication process, the S5 can’t be reasonably expected to compete with modern 16nm or 14nm ASIC designs in terms of hashrate or power efficiency.

Is there still a place for the venerable S5?

If you’re a hobbyist miner on a budget, with no interest in the profitability of transmogrifying electricity into bitcoins, then the S5 is worth considering.

Power Supply

The S5 will draw between 560 to 590 Watts at around 115 Volts. Any sufficiently-powered ATX Power Supply Unit will run the S5 without problems.

That means that your old PC power supply – or someone else’s second hand one – can be easily repurposed for Bitcoin mining.

Note that the efficiency of power supplies is rated as gold (10% of electricity wasted), silver (20% wasted) or bronze (30% wasted).

The efficiency of power supplies is a worthy topic of investigation for any aspiring Bitcoin miner; inefficient, unrated power supplies will waste electricity and create extra noise and heat.

A list of PSU ratings may be found here.

Recommended for use with the S5:
Ideally, get a PSU from the Corsair Enthusiast Series Bronze Certified PSU; either the 650 or 750 Watt model.

The 650W model is available second hand for a little over $100. Corsair has a good reputation among Bitcoin miners and other tech enthusiasts for building reliable hardware. The Bronze series offers good value.

One thing to note is that under-clocking the S5 is difficult without a special, 9 Volt-capable PSU.

Power Efficiency

The S5 will produce 1 Gigahash for every 0.51 Watts it consumes. This figure can be expressed as 0.51 J/GH.

The S5’s real power consumption, as measured by your electric bill, will vary depending on your PSU’s efficiency and the ambient temperature.

0.51 J/GH is a lot more efficient than the S3 (0.78 J/GH) but a lot less efficient than the more expensive AntMiner S7 (0.25 J/GH) or S9 (0.098 J/GH) models. Traditionally, each new BitMain miner series doubles efficiency.

It’s possible to upgrade the S5’s hashrate, primarily by increasing its frequency (aka overclocking) but this increases the miner’s power and cooling requirements.

There are ways, ranging from simple to extreme, to manage the overclocking burdens. Gains of up to ~400 GH/s are achievable but require serious effort. This video demonstrates oil immersion cooling.

Casing

The S5 is open at the top and bottom and the sides are constructed of fairly lightweight plastic.

This limits the placement of the unit and somewhat reduces its safety. One upside of the plastic casing is that the unit only weight 2.5 kg. / 6.5 lbs.

Noise

The noise from a stock S5’s 120mm fan has been compared to an industrial vacuum.

It’s definitely an unsuitable device to run in your living environment; it’ll drown out conversation and irritate people or pets.

The only solution is to replace the stock ~75 decibel fan with a quieter kind. Often a secondary fan is added to the back-end, where screw holes exist for this purpose.

Setup

The S5 will automatically search out an available IP address to use and features an intuitive control panel.

The MinerLink software will allow you to monitor the status of your miner(s), easily configure your mining pool settings, upgrade the device’s firmware and share access privileges to the miner over a network connection.

Temperature
Onboard temperature must be maintained below 80^C / 175^F. Keeping the onboard temperature below 60^C / 140^F will prolong the lifetime of the S5.

As with all miners, the lower the operating temperature, the higher they can be overclocked.
