Efudd’s modified firmware for the Bitmain AntMiner Z series ASIC miners now supports the Bitmain AntMiner Z11 with its latest update to version 2.3, AntMiner Z9 is supported by version 2.2 and for the AntMiner Z9-Mini you need to use the version 2.1d. The modified firmware allows for more advanced overclock including frequency and voltage tuning with voltage controls per hashboard option available. With the modified firmware it is easier to achieve higher performance than with the stock firmware that has limited OC capabilities by Bitmain. According to the developer of the modified firmware 150+ KSol/s (up from the stock 135 KSol/s) should be doable with minimal tuning and further increase to 170-180 KSol/s might be achievable with more power, careful tuning, good cooling and some luck.
Do note that the modified firmware comes with a built-in 3% developer fee, so the miner will be mining for the developer 10 minutes out of every 330 minutes it is operating.

The newest NBMiner 21.4 update comes with further improvement in the performance for Grin31 mining (Cuckatoo31 algorithm), though slight one from what we are seeing, the miner is still probably the fastest Nvidia GPU miner for Cuckatoo31. There is also performance improvement for Grin29 (Cuckaroo29) and AE (Aeternity) on Nvidia RTX cards and the current level of performance is almost on par with other competing miners in terms of hashrate on GTX 1080 Ti GPUs, though the latest GMiner 1.36 still has a slight performance advantage on GTX 1080 Ti under Windows at least.
NBMiner v21.4 also fixed Grin31 compatibility on Windows 7 with 8GB video cards and comes with a new option to reduce the range of power consumption by multi-gpu rig (--cuckatoo-power-optimize). The use of this option could prevent power spikes from causing problems with power supplies that are near their limit and thus can help improve mining system stability, though there may be some drop of mining performance as a result, so do try the option and see it it helps or not improve system stability and ho it affects mining performance in your case.
We remind you that the NBMiner is a closed source GPU miner for Nvidia CUDA that is available for both Windows and Linux operating systems and it has the following developer fee built-in: tensority + ethash – 3%, tensority (Pascal GPUs) – 2%, tensority (Turing GPUs) – 3%, ethash – 0.65%, cuckaroo29 and cuckatoo31 – 2%.

The new Bitmain Antminer Z11 ASIC offers a hashing power of 135 KSol/s for the Equihash algorithm used by ZCash (ZEC) and other crypto currencies and is essentially the successor of the Antminer Z9 from the last year that offered 40 KSol/s and the Antminer Z9 mini that was just 10 KSol/s. The Antminer Z11 uses Bitmain’s latest proprietary 12nm chip, which is made using advanced Bare Die molding technology for better heat dissipation and has a power-efficiency of 10.50 J/KSol, so it is with significant improvement over the older hardware. The recommended power supply for this miner is 1800W, though the actual like the APW7 PSU from Bitmain, though the actual power consumption is lower (1418 W power consumption claimed). The current price of the Antminer Z11 is $1242 USD and shipping should start around the end of April (20-30).
