Gridcoin mining for heat started to payoff

in gridcoin •  27 days ago

Hi everyone,

Weather was shitty in the past few days.

It was raining (with cats and dogs) for 20 hours. Now it stopped, but temperature outside dropped dramatically. At 9AM, when I started to write this article, temperature was 6°C (42.8°F).

My effort to bring up my HD7990 and crunch data for Gridcoins, started to payoff. PrimeGrid is generating computational errors on the Genefer work units, but Seti@Home runs smoothly.

The temperature in my apartment reached a decent 21.1°C (70°F) with one HD7990. I'm aware that the GPU is sub-optimal, as the temperature of the radiator is nothing compared to the old times when they mined LTCs.

SETI@home is not very GPU intensive. Their GPU application also utilizes CPU for some calculations, so a lot of data is shuffled between the CPU and the GPU which makes a 100% GPU workload unlikely.

There are BOINC applications which could easily outmatch the power consumption of LTC hashing, for example Primegrid GFN-22 (looking for very large prime numbers). But if shorter GFN tasks are failing on your GPUs, GFN-22 will more than likely fail too. It could be that those tasks are failing precisely because they are hard on the GPU.

Thanks, @vortac!
It looks that PrimeGrid works perfectly with the old GeForce GT630 in Ubuntu 16.04. I will let this one working on PrimeGrid for a while, and use the time to find a solution also for the HD7990.

Many thanks for your support!

You'll likely making enough money on SteemIt to pay for your electricity bill too ;-).

Sorry, couldn't resist.

Yes, that's probably true!
I found that the Gridcoin community here is really amazing!
