nheqminer - open source & free CUDA ZEC (GTX 1070 @ 400 Sol/s) miner by NiceHash

Great!

Mining on nicehash as thanks for the great nvidia cuda support.

Anyway even if nicehash takes 3%, just mining it and never worrying or exchaning ZEC for BTC is worth it, if your time is valued less than 1USD per hour, only then you can "invest" your time in mining on other pools and exchaning your zecs manually.

the difference is far greater, now using this open source miner to mine on any pool give me roughly 50% more profit than mining on nicehash directly

if you call this only 3%, then your math is wrong on unbelievable level

you math is flowed, you can have 50% more onlu if pool luck is 40% over calc which is insane, and be sure pool luck for zcash sux... so do you test proper
I have minened for weeks on nicehash and on other pools and difference is few % more or less depending on price, diff, pool luck , etc

same hash on whattomine one give me $7 the other $4.5, this is the average 24H

whattomine is pretty accurate, the myth that whattomine is wrong is more than wrong

For last 7 days, difference on what to mine is 15%, and you can bet none pool will give you 100% from calculator on zcash, nad nicehash payout is 100% to it, because it has nothing with pool luck

i tested it, suprnova is giving me around the same as what whattomine say, it's accurate as i said, nicehash payout vary but it's always far less than mining on normal pool, not 3% at all

I can not understand. when a miner drawing hashes speed in the log, I hear a pause in the choke and power sags at this moment, how to remove these interruptions? Sorry for my eng...

[alucard20724]

it looks like this just has the eqm 0.4c in it... is that a correct assumption?

[wacko]

There seems to be something wrong with this miner (or the windows build in particular) - like Tomorrowman, I'm also having the load jumping all over the place, and there are other users reporting the same issue.

[laik2]

If something is wrong it's open source so someone with CUDA knowledge will fix it soon. Just wait

This miner has some cpu load issues, nicehash team noticed about it in there first posts.

Miner involves cpu in removing fake results in last round.
The duped() function is slow, especially on celeron, in 6-card rig GPU load is only 92-93%. The host code must be rewrited, allowing executing GPU code and CPU code simultaneously .
The second issue is speed reporting, it causes some cpu load.
I made some dirty fixes, GPU load is 97% and speed went from 395 to 435 on overclocked 1070, but it is slower then Ewbf's miner.

Can you share your changes?

[reb0rn21]

For me with two thread speed is ~1-2% same as eqm miner, if GPU usage drop would be fixed, speed would be same

I set debug level from 2 to 4 (-d 4)  and i have much less load jumping now (I think this is because the miner is not showing hashes speed on this debug level), but the power is still sometimes jumps

We wrote there in source code what can be improved. The task needs some rewrite in main loop (that calls solver). Once this is done, there will be no more GPU load drops and less CPU load.

https://github.com/nicehash/nheqminer/releases/tag/0.5c

Windows all in one build.
Ubuntu (16.04 and 04.04) Linux bulds (only cuda_djezo and avx support, for now).
There is still a lot of room for improvement. First Linux all in one build, after that automatic solver chooser based on device capability, etc.

have on gtx 750 this error:

CUDA error 'an illegel memory access was encountered' in 'func eq_cuda_context<RB,SM,SSM,THREADS,PACKER>::solve' line 2095.

is miner suport gtx750?

 GTX 750 ti doesn't support CUDA 8 as I recall, so probably not unless you recompile.

[_javi_]

it´s a shame..

i cant pass 1450 sols with 4 x G1 1070 (no OC)...

Is it so hard to run miner with option  CD 0 0 1 1 2 2 3 3 ??

It seems you can't go above 6 thread for one instance of the miner, with a 6 card rig i put -cd 0 0 1 1 2 2 3 3 4 4 5 5, but it only open 6 thread making the last 2 cards not used, was able to circumvent this issue with running 3 instance of the miner both with 2 cards. Seems to match EWBF, but overall sol/s across instances seems to be less stable.

EDIT : it seems with the release of 0.5c they upgraded the instance count, gonna try it !

EDIT2 : ok new version 0.5c support more instance so you can double thread 6 cards, but it only support 2 thread per card. Still plagued by the GPU usage going up & down, we're close but not quite there yet.

Keep up the good work

it would be nice if somebody compiled the miner for old cards.i can myself,but i need to install ubuntu and understand the system of compilation and possible errors.if someone will do it quickly and it is not too much trouble,i would be very grateful for that.and I think I'm not the only one.

You don't need to install ubuntu you can as well compile with any other linux distro or windows. What os are you using?

What Linux distro (I am assuming you mean Linux) do you need? Builds with CUDA 7.5?
