Here is the detailed guide for you to underclock your Whatsminer with factory firmware.
TLDR
- Have a whatsminer M3X
- Update newest Whatsminer firmware release and Whatsminer Tool (Requires Windows PC)
- To achieve notable efficiency improvements, use Adjust Frequency down. There will be a decrease in hashrate.
- Purchase a clamp meter as an option to gauge wall-mounted power usage. Verify; don’t rely on the software.
Kilowatt hours are breakfast for the beast that is whatsminer. When compared to its rival, the Antminer S19J Pro, which is rated at 29.5 W/TH, an M30S++ 100-110T is rated at 31 W/TH. Compared to the Antminer, the efficiency is reported to be 5% lower. And that significantly affects the power bill. Keep in mind, though, that many amateur miners will choose the Antminer. Further, with aftermarket firmware such as Braiins OS+ or VNISH you can tweak the settings to overclock or underclock any of the It doesn’t matter how much more efficient Antminer rigs are compared to Whatsminer; I still prefer Whatsminer.
At home, where hash prices are low, miners strive for maximum efficiency. The more creative the miner, the higher the efficiency. These guys have come up with inventive ways to recycle waste heat into their HVAC systems, even how to heat their homes’ water, and some have even heated their pools and dried laundry with the extra heat. In essence, this enables the miner to double his or her utility bill expenditures. However, since the spring of 2021, the price of hash has fallen dramatically.
Hashprice as Defined by Luxor
One TH/s of hashing power per day is expected to be worth a certain amount of money, or hashprice, according to Luxor. The metric measures the expected profit a miner can expect from a particular hashrate level. We display the metric in terms of USD or BTC (sats), though Hashprice can be expressed in any currency or asset. For example
– $0.20 per terahash/second per day ($0.20/TH/s/day)
– 475 satoshis per terahash/second per day (475 sats/TH/s/day)
Hashprice is a function of three inputs: transaction costs, network difficulty, and the cost of Bitcoin. Each time a block is added to the blockchain, the hashprice of Bitcoin will change. Transaction costs are taken into account by the 144 lagging SMA in Luxor’s Bitcoin Hashprice Index.
Hashprice is inversely correlated with changes in transaction fee volume and price of bitcoin, and inversely correlated with changes in mining difficulty.
We won’t be covering technical analysis or predictions in this article because not everyone is a nerd for them. Since reading tea leaves is not the point of this essay, I won’t bother. Luxor has provided the following chart with the Hashprice Index over the previous year. The hashprice is unmistakably tanking, as shown by the graphic representation of the downward sloping trajectory. While it appears to be rising somewhat steadily in the lower right corner in the first few weeks of 2023, we still have another year to be able to clearly analyze the data rather than making predictions. A positive trend is all we can hope for, but don’t be shocked if it dips and then rises once more. We are still early and our journey will undoubtedly be bumpy, that much is certain.
Other than the factory Low Power setting, Whatsminer owners have had few options for increasing efficiency. Since this summer, I have enjoyed using Low Power Mode. By using less power and lowering the Watts/Terahash, a user can hash more effectively when Low Power Mode is enabled. Efficiency gains between low power and normal modes can reach 10%. To enable more customizable settings, Whatsminer updated its firmware. In October 2022, they published an update to the Whatsminer Tool and firmware that offers greater flexibility and productivity.
Frequency and power limit settings are available in the most recent firmware update. For complete functionality, make sure to update the tool’s firmware. It is available on our website for download.
*The classic power modes are illustrated here from the tool user guide .Link *link-okk and to what or for what?
Adjusting frequency and power consumption is possible thanks to the October update. Only rigs that are cooled by water can use the up-frequency option. In order to improve efficiency and reduce the W/TH (J/TH for our non-U.S. readers) for the common folk with air-cooled rigs, the frequency can be lowered or power limited. pleb miners). Though I haven’t played around with it much, I can tell you that I was able to lower the W/TH more than the standard Low Power Mode.
In Addition to Frequency Adjustment There is Also a Power Limit Setting.
I have been operating a few M30S++ at a -30% frequency, and I am getting around 27 W/TH. I also made adjustments to one with a 1,930 watt power limit, but the results were less successful. Below are three M30S++ 110T models that have had their frequency and power limits adjusted. It appears that the frequency adjustment is more effective than the power limit set to a comparable wattage.
Selecting the IP addresses in the tool you want to change will allow you to execute the Frequency and Power adjustments in bulk. For those thinking, “what is the reading on the wall?” I understand; however, when I spot-check the WM tool data with my Iotawatt, I see a difference of +/- 10 to 20 watts between the two data points. The data from the WM tool closely matches what I can deduce from the circuits.
I was motivated to write this quick post because I keep hearing people say that they wish they could change the wattage on their Whatsminer. Yes, you can, because the efficiency improvements are worthwhile. Additionally, I want to point out that this release was made prior to Antiminer’s Christmas gift. Hope this saves someone some fiat on their electricity bill while hashrate, difficulty, and electricity pumps.
Happy Hashing
