Innosilicon G32 500 Grin Miner

Innosilicon G32 500 in Dubai

Innosilicon G32 Miner Project was discontinued in January 2020


Innosilicon G32-500 is a Grin miner that runs Cuckatoo31 algorithm with a maximum hash rate of 100 H/s at 520W power consumption.

Warning! Beware of scam websites selling Innosilicon G32 Grin miners. The project was failed due to technology challenges in manufacturing. So Innosilicon officially cancelled the G32 Grin miner project on 16th January 2020. Any company or website claiming to sell Innosilicon G32 is not true.

Innosilicon G32 Grin Miner is designed for full compatibility of Cuckatoo31+ and Cuckatoo32+ algorithm (backward compatible with Cuckatoo29/30 as well) in the same hardware.

The first batch of pre-order is expected to be delivered in January 2020. Subsequent pre-order delivery will be based on pre-payment sequence and it won’t be long after.

Other Variants

  • G32-Mini PCIe Card (Wifi capable)
  • G32-1800

Innosilicon invested a large amount in the G32 Grin miner R&D to complete the innovative CC31/CC32 Grin GPU ASIC design. Innosilicon believes in Grin and its core team. Grin is a great coin with a bright future. In order to better support the challenging Grin phase-out evolution path, they made the chip programmable for multiple purposes for best values. This challenging design was completed in September 2019 and put into foundry for production.

Innosilicon did not expect that the foundry kept delaying this production week after week by performing so much so called “yield check” citing big die size concerns which eventually lead to infinite delays until Innosilicon shutdown the project and started refund of pre-booking payments.

Note: Innosilicon also offered 15% discount coupons to all those who booked during the pre-booking period.

Power Supply

The Innosilicon G32 Grin miner comes with built-in original 220V/110V PSU for safe and efficient Grin mining.

Caution: Wrong input voltage may probably cause miner damaged and shall not be covered by the Innosilicon warranty.

Operating Condition

Max temperature 40°C, altitude 0m.

Grin Mining Difficulty

The current minimum share difficulty (4) is very high for C32 miners. As such, mining pools are introducing a lower minimum share difficulty for C32 miners. But read their terms and conditions carefully before you connect your miners to the pool. Violating their terms will disconnect your miners from the pool immediately.

Solo Mining Vs Pool Mining

Although Solo mining is feasible with Grin mining, it is recommended to join a big pool of miners.

Innosilicon Warranty

All Innosilicon Grin G32 Mini, G32-500, and G32- 1800 Miner will be tested by factory before shipment and certified by Innosilicon. The post-sales 180 days parts warranty is eligible for all miners.

If any problem, please leave an after-sales message on Innosilicon message board. Their technical support team will get in touch with you ASAP.

Please don’t send any machine or parts without contacting the technical support team first. Any loss or damage as a result of lack of contact will be the responsibility of the customer.

Please note that the following events will void the warranty:

  • Miner is demolished, privately altered or component replaced by customers;
  • Damage caused by lightning, voltage surges and poor quality power supply;
  • Circuit boards and components damaged by water, exposed to moisture or corroded;
  • The circuit board or the chip is completely burned;
  • Excessive overclocking in an overheating environment;

If one of the cases above happens, you shall be charged for your miner maintenance services. For the specific procedures, please refer to the after-sales process.

Note: Please ensure your miners are taken care in a proper farm with cooling and dust filter conditions. Warranty expires if you overclock miners or running miners at excessive heat or dust conditions beyond our target range.

For all repairs, within warranty or not, customer must return the defective parts at their own expense after opening a support ticket and troubleshooting with Innosilicon’s instructions. 

Grin Mining Pools

GrinMint (Recommended) (PPLNG / 2% pool fee + 0.5% fee to Grin Developer fund. Total 2.5% Fee.)

F2Pool (PPS+ / 3% Pool Fee)

Sparkpool (PPS+ / 1% Pool Fee) (PPS+ / 1.5% Pool Fee)

TheGrinPool (PPLNS / 0.5% Pool Fee)

GrinCoin (PPLNS / 0% Pool Fee)

NanoPool (PPLNS / 1%)


Note: To prevent abuse, GrinMint will only allow C32 shares on a low difficulty C32 miner. If you send C29 or C31 shares, your miner will get instantly be disconnected by GrinMint.

The current minimum share difficulty (4) is very high for C32 miners. As such, we are happy to introduce a lower minimum share difficulty for C32 miners.

To mine at low difficulty for C32 miners, your worker’s name MUST finish with "-c32".


How to reduce the noise of Innosilicon G32 Grin Miner?

Try our Crypto Mining Rack that can reduce the ASIC miner noise levels and manage heat ventilation as well. This will allow you to run ASIC Miners even inside your office or home. The Rack enclosure can accommodate up to 20 ASIC machines per rack based on the ASIC miner model.
