NVIDIA GTX 1080 ti GPUs


#592

Yea…what algos are you referencing @TeamGreen?


#593

he talk for 1070 TI , but im not sure this will be save long time


#594

Thank you, interesting answer.

What are more profit algos?
Did you REinvest or just buy more rigs?


#595

Unfortunately, but… True…


#596

what is true?
which are the other algos? pretty interesting thing, tbh!


#597

:slight_smile: My comment is related to Kosteg’s comment. But not to TeamGreen’s.


#598

Please correct me if im wrong but I think what he was trying to say is using a gpu other than a 1080ti there are other algos. The 1080ti is very power hungry compared to other gpus. Its best purpose is equihash. Once in a while you see some other algos rise above but from what i track the equihash algo and 1080ti goes hand in hand.

I’m running a nice little mining rig with 6x strix 1080ti, getting around 710-715 sol/s at 200w each, running ewbf-0.3.4b on SMOS with stable OC.
I was planning to extend the rig to the maximum capacity of 13 gpus, continuing with the strix cards, but I came across an opportunity to buy Galax 1080ti HOF air cooled cards for pretty much the same price (around 1020 usd). I can’t seem to find much info about the Galax HOF, but ppl seem to be hyped about it.
Could you guys share some knowledge about the sol/s I could get efficiently?

ps. Sorry for my bad english

I wanted to make a quick update.

Since this was posted I’ve switched all of my rigs over to Linux.

Although the EVGA water-cooled 1080ti SC2 cards are not able to be controlled in Linux, when you run them they have their own internal temperature control. This basically means that they do end up running at 80-100 fan speed once the temperature gets higher and that they stay cool enough to consistently mine at 750-760 Sol/s while staying
<=60c.

I do like to run my cards at max fan speed, but the EVGA’s internal settings allow you to use 12 of them on one rig while not having to worry about the fan speed. Pretty neat and overclocking is still possible with nvidia-settings and nvidia-smi.

Another thing is that the Aorus waterforce 1080ti is also amazing, but the downside is that it requires two 8-pin power connectors instead of one 6pin+8pin connector (note: make sure your PSU cables are rated for 6pin+8pin in the first place).

Best of luck!

running 3x GTX1080TI GAMING OC 11G underclocked to roughly 620 sol/145-150W each. pretty stable. mobo and other things except PSU(1000W) and risers - junk, second hand, cost nearly nothing, but allow to start up to 5 cards per mobo. EBWF 0.3.4.b miner.
stock runs at 720 sol/260-270W each
considering my electricity cost - underclocking is the best option.

Everybody, using risers, check the connectors, in my batch freaking Chinese got the wiring of the 6 pin connector wrong, creating a shortcut! Luckily my PSU was smart enough to prevent any damage. So, guys, always check the wiring (yellow and black wires going to connectors)…


#602

Forgot to say, the cards are GIGABYTE


#603

The underclocked cards run stable at 58-60 Celsius at 70% fan or so (in the closed case - mining case designed for 6 cards), it’s still hot here, ambient temperature about 29-30 centigrades Celsius, waiting for winter to kick in…
Stock ran at 90% fan, same temperature around 60C, but with the open case only, closing it rose the temperatures to 77 C…
Adjusting memory clock doesn’t have any effect at all. Now they run at 59% power, +223 core clock. 0 memory adjust.

Did cops busted down your door with a drug related search warrant yet?

That’s only possible if some one build a decoder optimized for the ZEC mathematical problem.

When you put 1+1 in your calculator Decodes it and spit out a 2.

There is a couple ways to do it that I’m aware of.
1: the calculator has a adder, which does bit addition. This would be series. The period T = # of terms *clock cycle for a single addition.
2: The decoder reads 1+1 and spit out an series of ram address. And load each bit to the coorsbonding answer bit location. This is a parallel process. The period is a finite clock cycle. Depend how each bit is loaded to the output.

Each of them can be fast for specific stuitions. The 2nd is most lickly the choice for complex problems. Optimizing it would be a challenge for GPU, because it’s for general computation. It has lots of unnessary process for mining. These process all require some clock cycles to run. If you can get rid of it, then you have a optimizes ZEC decoder, because it does nothing but spitting out answers for ZEC’s mathematical problem.

Does it exist? Well, who the fuck is going to build a decoder that’s capable of decoding every possible ZEC mathematical question then map it to a RAM?
Don’t forget ZEC team can change the questionat any time.

Will a quantum computer help??


#607

Why not just save the investment for a quantum computer and enjoy the rest of your life? I assume we are 1million years off and countless money away from a quantum computer. That’s a lot of money and time you could have saved.


#608

No it won’t, as said before:

And still no, soon enough block chains will be quantum resistant, I know for sure that zcash is working on it with some very credited people (zn stake? how was the name?). I would say max 2020 most coins will be quantum resistant, and having a quantum machine instead of your pc or even smartphone will propably never happend (never say never).


#609

You can’t have a quantum resistance mathematical problem, and expect others to solve it. The fact that a quantum machine takes forever to solve is the same as impossible solution. Like looking for the biggest number or biggest number number between 1 and 1.1, or the last digit of pi. They Cannot be computed. (I guess there are only 10 possible answer for last digit of pie).


#610

Here is the logic I was refering to: https://www.coindesk.com/zk-starks-new-take-on-zcash-tech-could-power-truly-private-blockchains/


#611

ok, it has literally nothing to do with quantum resistance, I’m going to get my facts straight. Ha!
