Re: 8th Alt coin thread. Or what to do now that asics are all over the place.

This year I am no longer focusing on what gear to use.

But how to expand my cheap reliable power.

If the new focus is on surviving and counting on cheaper reliable power, what do you guys think about optimizing mining rigs with 19-GPU builds?

From what i've seen most are simply running 13-GPU rigs with pure or mixed AMD / NVIDIA GPUs but i believe true efficiency lies in maximizing the 19-GPU capable ASUS B250 mining expert motherboard. With 19 GPU builds you save on electricity by running less motherboards, CPUs, SSDs, etc.

Has anyone had any experience in using p106/p104 mining cards to build truly efficient 19-GPU rigs?

I did have my hands on a 16 card beast did a review but it had the p106 which is like the 1060 it is simply not that efficient.

the p102 is better but is costly

it is a modded 1080ti. I would have loved to have had the p102 that they were looking to build I may have kept it after the review.

When it becomes more available to the public, i agree that the p102 will be a much better option.

But i'm also interested in stability. Don't know exactly where i read it from, but some have said that 19-GPU builds are a pain to build and are a hassle to maintain? Does this mean 19-GPU builds regularly crash or require more constant attention compared to regular 13-GPU builds?

the 16 card had a special back plane and run not stop in a 95f room for 5 weeks zero issues rock solid gear.

Just not that efficient.

a 19 card build with carefully tweaked risers would be better power wise, but if all 1080ti's it would be hard to power or cool.

it would pull over 3000 watts more like 3500. It would need 2 delta 2400 watt plus'
