Iceriver KS2 Specifications

Specification note: The Iceriver KS2 is rated at approximately 2TH/s and 1,200W. This produces a calculated nominal efficiency of approximately 600J/TH.

The original August 2023 release date has been replaced with March 2023 because IceRiver introduced the KS1 and KS2 during that period.

Iceriver KS2 Kaspa Mining Performance

The Iceriver KS2 performs approximately two trillion kHeavyHash calculations every second under nominal operating conditions.

Actual local hashrate can vary because of firmware, temperature, voltage stability, fan performance, production tolerances and machine condition. Pool-side accepted hashrate may also move above or below the local reading because of network latency and share timing.

Factors That Affect Mining Output

• Firmware version
• Ambient temperature
• Airflow quality
• Fan condition
• Input-voltage stability
• Ethernet reliability
• Pool-server distance
• Rejected shares
• Stale shares
• Miner uptime

Operators should compare the local Iceriver KS2 dashboard with average accepted pool-side hashrate over several hours rather than relying on short-term peaks.

Important Monitoring Values

• Current hashrate
• Average pool-side hashrate
• Accepted shares
• Rejected shares
• Stale shares
• Hashboard status
• Miner temperature
• Fan speed
• Ethernet uptime
• Measured wall power

Iceriver KS2 Power Efficiency

The nominal efficiency of the Iceriver KS2 is calculated as follows:

1,200W ÷ 2TH/s = approximately 600J/TH

The same efficiency can be expressed as approximately 0.6J/GH.

This published efficiency is similar to the KS1 because the Iceriver KS2 provides approximately twice the hashrate while using approximately twice the power.

Efficiency measures power used per unit of hashrate. It does not guarantee mining income or a specific return period.

When comparing the Iceriver KS2 with other miners, consider:

• Total hashrate
• Power efficiency
• Hardware price
• Electricity cost
• Cooling demand
• Pool fees
• Noise output
• Power-cord requirements
• Warranty support
• Expected useful life

Iceriver KS2 Kaspa Compatibility

The Iceriver KS2 is designed for the kHeavyHash proof-of-work algorithm used by Kaspa.

Kaspa is a proof-of-work blockDAG network. Current Kaspa mining is performed primarily with specialized ASIC hardware rather than CPUs or GPUs.

The Iceriver KS2 is not designed for unrelated algorithms such as:

• SHA-256 used by Bitcoin
• Scrypt used by Litecoin and Dogecoin
• RandomX used by Monero
• BLAKE3 used by Alephium
• NexaPow used by Nexa
• SHA512256d used by Radiant

Learn more through the official Kaspa website, review the Kaspa mining documentation, and download the official IceRiver KS1 and KS2 manual.

Iceriver KS2 Pool and Solo-Mining Setup

The Iceriver KS2 connects to compatible Kaspa mining pools through wired Ethernet.

Pool configuration generally requires:

• A compatible Kaspa Stratum address
• A Kaspa wallet address or pool account
• A worker name
• A pool password
• Secondary and tertiary backup pools

Pool Selection Checklist

• Kaspa ASIC compatibility
• Pool fee
• Payout method
• Minimum payout threshold
• Regional server availability
• Historical uptime
• Worker-monitoring features
• Customer support
• Pool hashrate concentration

After configuring the Iceriver KS2, verify that accepted shares appear and that average pool-side hashrate remains reasonably close to the rated performance.

Solo mining is technically possible, but pool mining generally provides more frequent payouts for miners representing a small share of total network hashrate.

Iceriver KS2 Electrical Requirements

The Iceriver KS2 requires approximately 170–300V AC and should not be connected to an unsuitable low-voltage outlet.

Approximate current at the nominal 1,200W load is:

• Approximately 7.06A at 170V
• Approximately 5.45A at 220V
• Approximately 5.22A at 230V
• Approximately 5A at 240V
• Approximately 4A at 300V

Actual current may vary because of power factor, PSU efficiency, operating temperature and machine condition.

Electrical Preparation

• Properly grounded high-voltage outlet
• Suitable circuit breaker
• Cable rated for continuous load
• C14-compatible power cord
• Surge protection
• Secure power connections
• Accessible emergency disconnect
• Compliance with local electrical codes

IceRiver states that the power cord is not included. Prepare a suitable C14-compatible cable before installing the Iceriver KS2.

A qualified electrician should inspect the circuit when there is uncertainty about voltage, grounding or breaker capacity.

Iceriver KS2 Cooling and Noise

The Iceriver KS2 converts approximately 1,200W of electrical power into continuous heat. It therefore requires reliable intake airflow and an effective exhaust path.

Although the KS1 and KS2 were originally promoted with a lower noise figure than many larger industrial ASIC miners, actual sound depends on fan speed, room temperature, dust buildup and placement.

Cooling Recommendations

• Keep intake and exhaust openings unobstructed.
• Place the miner on a stable rack or shelf.
• Avoid sealed cabinets and boxes.
• Separate warm exhaust from cool intake air.
• Provide additional room ventilation where necessary.
• Keep ambient temperature below 35°C.
• Remove dust from fans and heatsinks.
• Keep power and network cables away from exhaust heat.
• Avoid moisture and condensation.
• Monitor temperature continuously.

IceRiver identifies the internal fan used by the Iceriver KS2 as model 12038.

Iceriver KS2 Maintenance

Routine maintenance helps the Iceriver KS2 maintain stable cooling, Ethernet connectivity and accepted pool performance.

• Inspect intake and exhaust openings.
• Remove accumulated dust carefully.
• Check the internal fan.
• Monitor miner and hashboard temperatures.
• Inspect the power cord and connector.
• Check Ethernet cables and network switches.
• Compare local and pool-side hashrate.
• Review rejected and stale shares.
• Back up settings before firmware updates.
• Use only firmware intended for the KS2.
• Disconnect power before cleaning.

Do not install firmware intended for the KS1, KS2 Lite, KS3 or another IceRiver model unless the manufacturer explicitly confirms compatibility.

Official software is available through the IceRiver firmware page. Incompatible or unofficial firmware may damage the miner and affect warranty coverage.

Iceriver KS2 Model Comparison

The Iceriver KS2 sits between the KS1 and higher-output KS3-series miners.

• KS0 Pro: Approximately 200GH/s at 100W
• KS0 Ultra: Approximately 400GH/s at 100W
• KS1: Approximately 1TH/s at 600W
• KS2: Approximately 2TH/s at 1,200W

The Iceriver KS2 delivers twice the nominal hashrate of the KS1 while consuming twice the nominal power.

Compared with the KS0 Ultra, the KS2 delivers approximately five times the hashrate while consuming twelve times the nominal power.

Always verify the exact product label because the KS2 and KS2 Lite are separate models with different specifications, cooling systems and intended use.
