If you have LHR RTX 3060 12GB cards, I recommend mining ETH+CFX with T-rex. You can get 20% more profit than ETH alone at a power limit of just 80%.

It'll be interesting to see what happens after PoS. I think we'll see as big of a crash as 2018, then profitability will recover in a few months.

I 100% agree. Actually, 96% of the market cap of GPU mineable coins currently comes from ETH. That could be as much as a 96% collapse in total mining revenue available (although this doesn't consider differences in block rewards). The folks buying video cards at inflated prices today will be the bag holders, if ETH 2.0 goes according to schedule. Of course, if the merge gets delayed by 3 months, they'll probably break even.

The miners who will make profit are those who wait for the crash, buy mining equipment at 50% below MSRP, mine while difficulty is low for a few months, then sell when difficulty recovers. They also have to have a decent power cost (< 10¢/kWh) and need to know the tax incentives available.

Personally, I can't wait for the PoS merge. Right now I'm buying different models of video cards to test them on different algos and learn. When GPU prices crash, I will buy hundreds of cards and pay 5-6¢/kWh (after tax) for power.

First, quality USB watchdogs cost $10-20 and some still have 3-star reviews. Most importantly, they can't detect every single mining issue and fix every issue. Watchdogs rely on signals from the OS and all they can detect is an OS freeze. Also the user has no control and can't temporarily disable the watchdog. Resetter RF will allow you to control everything and manually reset.

Update: I have new pictures of the RRF hub.

A proprietary algorithm that we're going to develop. It will work with a bunch of popular mining softwares, not just Claymore.

We're just repurposing existing radio-controlled outlets, which were designed for smart homes and stuff, to be useful for GPU mining.
There will be a feature to temporarily disable automatic control if you're working on the rig so that it doesn't reset infinitely.
Sometimes the motherboard can be finicky at powering back on after a blackout is over. I've noticed this with Gigabyte Z270x-Gaming 5's. Or multiple PSUs need to be turned on in the right order.

Resetter RF isn't the solution to all rig crashes, but it'll prevent occasional random hangs, the rig getting stuck offline after a power failure, and freezes while changing OC settings or algorithms.


Sorry about the lack of diagrams and pictures; the project has just started 2 weeks ago.

Very early prototype of the RRF hub:



Example of mining rigs connected to the outlets:




What I did here is power the MOBO with a 400w ATX PSU and power the video cards with a HP server supply. The ATX's power goes through the RF outlet and is switched.
The device doesn't restart the Claymore software, it just hard reboots the machine (or whatever PSU's it's connected to). If the OS and/or Claymore are already frozen, a hard reset is the only solution.

P.S.: the current US outlets support 240 volts and can connect to a C14 PDU socket with a little adapter. They've been tested on 240v for months.

Hello miners, my name is Hammereditor and I'm from Coinfarm Ventures.

In January I started my own mining farm with 200 video cards. The only problem: the warehouse was 100 miles or 2-3 hours away in another state. We just couldn't get a reasonable electric rate here in Long Island. At first it was a nightmare: I had to use expensive Wi-Fi smart outlets and deal with offline rigs. Every single week I had to visit the facility.

I bet many of you struggle with rig crashes, blackouts and GPU stalls. Not just large miners, but small hobbyists too. Until I crafted a little rig resetter for way cheaper than Wi-Fi outlets or smart PDUs. It solved 90% of crashes, eliminated most lost profit, and saved me countless hours of traveling to the warehouse.

Now I'm turning it into an actual full-featured product that's built from the ground up with only one purpose: reduce mining-related downtime. However, I first need to know how many miners need or want Resetter RF and whether it's useful or not.

You can help by taking the market survey, which is 14 questions and < 5 minutes long. If you're located in the U.S. or Canada only, you have a chance to take part in the closed beta test 3 weeks from now and try out a prototype of Resetter RF for free for around a month. 10 beta units will be handed out. If you're not in those countries, though, you can still submit the survey, then PM me a request to participate.

In the future there will be support for international outlets (EU, AU, UK) and the control panel will be upgraded over time, but we're sticking to the basic features for now. The more interest there is in this, the more I'll discuss in this thread. That's all! Any questions or suggestions?
