Is anyone else on this? I'm using nvOC, 13x 1080ti, 6x p106, 8gb ram, g2620 CPU. Mining equihash at 11000 sol/s.

I can't get any ccminers to work, they all throw up cuda errors or crash immediately upon launch. So I'm missing out on vertcoin which is a bummer. Claymore dual and eth only works though, but sticking to equihash now as it's most profitable. My odd numbered cards get about 720 sol/s and my even numbered cards are 700 sol/s or below. Have no idea why. Thinking it has to do with the motherboard. Do we expect a future bios update to unlock the 13x limit? When?



Who else is on this? What are you mining?

Mobo is all set and waiting for 19 x P106-100 6GB, ETA 2 weeks. Should work right ?

[mikespax]

definitely. keep in mind I think my p106 speeds are quite low though from what I hear other people get. not sure if it's the mobo

[s3c70r]

Right, What gen speed you running on ? Mind sharing your clocks on these p106 ?

[jmigdlc99]

Nice rig. But those efficiencies are pretty bad. Is electricity cheap where you are from?

Not yet a 19-GPU ASUS B250 user but with my 12-GPU rig i make sure all efficiencies are above 3.0.
It should be easy to undervolt NVIDIA cards as they can easily be tweaked using afterburner.

Watt for an impressive setup !
But, unfornately the ~2.40/2.50 sol/Watt ratio is very bad.
Even with my old GTX750 (non "TI"), from the previous nVidia generation (2.5 years old), made a better ratio (2.56 sol/W).

[phuocduong]

maybe use 3 power 1600w

[mikespax]

I'm using the rig to warm my apartment, so I really don't care about the efficiency, just need it warm in here. But I will play with the power limit and overall profitability soon. I have three PSUs and one wattmeter so I really can't accurately measure stuff at the moment.

[s3c70r]

Hehe I just disconnected my baseboard to connect my PDU on that nice 30A 240V breaker to heat my place too.

I believe 19GPUs will run at approx 1900W so there's no way a regular 15A 120V can handle it. Buyers beware !

[shibob]

Your setup is really impressive. Btw I'm just curious that why hashrate of P106 is almost at optimum while 1080Ti did not get that high.

[mikespax]

If anyone can help me get my 1080ti hash rates up, that would be great. It's weird that every other one is low.

[DarrenJC]

Which sites sell the p106 mining gpu's? I just normally shop for gaming based cards

[QuintLeo]

The number of cards limit is not the motherboard, it is a DRIVERS limit.

 I think I remember seeing at least one of the P106 mining cards listed on NewEgg, and Amazon should have sources for most or all of them.

 You might need more CPU or more RAM to run that many cards on one motherboard.

Do you think there will ever be a time when this will work without mining cards?

[QuintLeo]

There is no reason for it to NEED mining-specific cards to run 19 cards.
Just tons of power connections, risers, etc.

 720 is kinda low for a 1080 ti at 100% tdp, unless perhaps they are FE cards (which have relatively poor cooling solutions and don't boost as high as pretty much any aftermarket cards do).
 I get that much out of my Aorus cards at 200 watts (80% TDP) +100 core +100 memory and very close on my Gigabyte Windforce and EVGA SC cards at the same settings.
 Which 1080ti cards do you have?
 Have you done any setting testing on core clock and memory clock on them?

[mikespax]

Got them running around 666 sol/s or 10200 sol/s total now as I dropped the powerlimits to reduce heat and noise. I have mostly founder's editions as well as a few gigabyte gaming OCs, 2 gigabyte turbos and two pny 1080ti blowers. Overclocks don't really have so much affect on hashrate with equihash I believe, but everything is running at 150+ core and 450+ memory.

Did you achieve 3.5 to 4 sol/J?

 Equihash can be wierdly picky about overclocks, sometimes MORE overclock gives less hashrate.
 It doesn't seem to be super picky about memory clocks though.

 My GTX 1080 ti Aorus pulls 620 sol/s at 150 watts (60% tdp) for a bit over 4.0 efficiency - which seems to be it's most efficient point or very close to it's most efficient point.
 GTX 1070 ti (I got my EVGA SC today) at 60% can manage quite a bit better than 4 - more like 4.4 - at +200 core +700 memory in afterburner (but the card UNDERCLOCKS the memory by default a little for some reason).

 Up side of the 1080 ti though is rig density and fewer cards to deal with, even if it IS a little less efficient than some of the alternatives.

Hi QuintLeo,

Would you mind sharing what are your core&mem overclock settings for the GTX 1080 ti Aorus 620 sol/s at 150 watts (60% tdp)? That s pretty good number you 've got there.
