Two of the largest miner software program for Grin, Bminer and Gminer, acquired an replace few days in the past. On this tutorial, we’ll stroll by the best way to mine with Gminer and what benchmarks (in addition to bugs) to count on. (Check this article if you wanna know more about Grin and why it might be a good idea to mine it)

First, let me make clear one thing to keep away from confusion. Grin could be mined through the use of few completely different algorithms. Cuckaroo29 is the official GPU-friendly ASIC-resistant algorithm and it’ll change into much less related as instances goes by till be fully changed by an ASIC-friendly algorithm in about 2 years from now.

Cuckatoo31+ is the ASIC-friendly algorithm that shall be related for few extra months till being changed by Cuckatoo32 (which is ASIC-friendly too).

Each miners I’ve talked about assist you to mine Cuckatoo31+ (the ASIC-friendly algo) with a GPU. Why? As a result of for now, mining C31 with a GPU is extra worthwhile than mining C29, as detailed under.

To obtain the newest updates comply with me on social media! 🙂

Bminer and Gminer Necessities

Cuckatoo31+ could be very VRAM-intensive. To mine it, you have to to have an Nvidia GPU with 8GB or extra VRAM. In principle, listed below are the suitable Nvidia GPUs:

  • GTX 1070
  • GTX 1080/ti
  • GTX 2070
  • GTX 2080/ti

I say ‘in principle‘ as a result of I haven’t managed to get my GTX 1070 playing cards to mine C31. I’ve been making an attempt to run a GTX 1070 below Home windows 10 nevertheless it failed with each the Gminer and the Bminer. I believe the issue is that Home windows 10 consumes an excessive amount of video reminiscence. It’s doable {that a} GTX 1070 may be capable of mine C31 below Home windows 7 however I haven’t examined that.

Additionally, I haven’t examined the Titan RTX series – when you have a type of playing cards, please share your benchmarks within the feedback.

The opposite essential requirement is tough drive/SSD house. Gminer requires you to allocate not less than 50 GB of free HDD house for digital reminiscence.

Bminer 14.3.0

I’ve tried Bminer with completely different playing cards however I haven’t managed to get it to work, sadly. It retains displaying me the identical error: “inadequate video reminiscence on gadget”. I’ve been making an attempt to run it on my Home windows 10 rigs and I believe the OS to be the issue.

Apparently, Bminer solely mines C31 below Home windows 7. None of my rigs have Home windows 7 and since Gminer is an honest various anyway, I haven’t bothered to put in Home windows 7 simply to strive Bminer.

Gminer – The way to Set It Up

Gminer proved to be Win10-friendly. Up to now, I’ve examined it with 3x 1080 Ti and 6x GTX 1080 Ti rigs and each mixtures labored fairly effectively.

Making the larger rig work was a bit tough – at first, one of many playing cards wasn’t hashing. Nevertheless, rising digital reminiscence from 42gb to 50gb did the trick and now your complete rig is hashing as anticipated. At first, I although that switching the show to the onboard GPU may remedy it however ultimately, it has nothing to do with it.

Right here’s the best way to make it work:

Gminer Mining Profitability

Whereas C29 is taken into account a GPU-friendly algorithm, it’s extra worthwhile to mine C31 as a substitute. As for right now, C31 mines 22% extra cash per hour than C29. The one cause to mine with C29 is should you don’t have a GPU that’s suitable with C31.

Thanks for studying. As at all times, your feedback, ideas and questions are welcome.
