EWBF's CUDA Zcash miner

[namjey]

Hey guys, I have two gtx 1080.
currently getting 481 and 489 sol/s each
power limit is 53% and 66%
Temp is 72C and 68C

Is it normal hash rate? or can I get higher hash rate?

Is equihash algorithm core intensive or memory intensive? what should i overclock?

@LoverAli94: I've used flypool and nanopool for some time to make a comparioson. Nanopool never gave me a high hashrate but the ZEC amount I was not what I was expecting. Flypool gave me a lower hashrate but the right ZEC amount.

About ping: I get 20-40 mostly. Sometimes when something is wrong I get around 200-300ms but my rejected shares are not really higher. I think in theory it's bad to have a high ping but it's not significant.

 I ran my farm on an Exede SAT connection (never saw less than about 650 ms, usually closer to 700) for a couple years - rejects were still under 1% though barely so.

 RELIABLE connection is more important than fast connection.

Yeah, you're right, my rejected share are that low too, or even less. i just thought it may have other influences that i haven't heard or considered.

Just for some additional feedback in regards to the effect on ping to rejected shares.

A few days back I setup a zen pool and with it running over the past few days with 0ms - 3ms ping times to my miners I have had basicly 0 rejected shares (0 rejects in the past 16 hours on 4 rigs after a pool restart).   So i would say that it would be fair to see an increase in rejected shares as your ping to the pool increases.

On a side note, if anyone would like to run on the zen pool pm me and I can send details, no plans for fees in the near future.  It is located in Australia.

Could someone help me with this issue?

I have mined ZEC before on this rig, but for last 2 weeks i have been mining SIGT and now that the profit in it has drastically dropped after 30k block, i was switching all my rigs back to ZEC and i ran into this issue.. very confused, i have restarted the rig multiple times.. no change..

You most likely have a slightly unstable overclock on your 1080ti's. 

What are you current settings for mem, core and power?

I am still trying to tune my 1080ti's, they seem to be a little bit more volatile than the 1070's.  It only takes 1 card to go down and then they all do.  So far I can keep them up on average for about 1 - 1.5 days before they go down.  Each time they go down i adjust my settings slightly until I can find values that are stable.

Just for reference my current settings are;

Mem - +155
Core - +128
Power - 85% (about 210 watts for my cards)

This gives me 710 - 720 sol/s.

But like i said, still trying to find that sweet spot where they will run for longer periods.

I just tried to run that rig on stock settings, 100/83/0/0/auto and it still doing it..

Im very confused, because i tried to run it back on SIGT, starts right up and mines just fine... also tried to mine DGB using Alexis CCminer, had invalid shares issue all on stock settings, but SIGT it will run overclocked and everything.. so confused.....

I would start by putting a large underclock on the memory, that allows more power to be provided to the gpu.

I would start off around -400 / -500 and see if that will run at the 83% TDP.  From what I can remember the ti's didn't really like to be undervolted on the gpu and i think that is how I ended up around 85%.  Those settings keep the core voltage above 900 mV.

I have 6 msi gaming X 1080 and get around 560/570 each gpu 3300/3400 sols all temp 55/58 and power limit 80%

Equihash is core intensive so to increase your hashrate you would need to overclock that. Depending on the GPU and your setup you might be stable at anywhere from +125 to +225 Core (in my experience). i typically leave the memory at stock, but some people underclock it abit.  You will also get a little higher hashrate if you run at a higher power limit, but whether that's worth it for you depends on how difficult it is to keep them cool (and your power  bill).

yeah make sure its a POWERED riser too..

the card needs power from the slot as well as the PCI E cables

I bought this exact model:

https://www.amazon.es/XCSOURCE-Extender-Adaptador-alimentación-AC579/dp/B01M6BIWCZ/ref=sr_1_3?ie=UTF8&qid=1502209285&sr=8-3&keywords=riser&th=1

I powered the card and also de slot-riser, I dont know whats the problem so.

LOOKS LIKE A DECENT RISER--

Looks can be deceptive.  Risers are evil creatures.  I am replacing all my risers with newer models.  Brand new risers can be bad.  Also, mixing slotted cards and risers can be a problem.

Sorry if I am not too clear.  Some motherboards are finicky, and will disallow certain PCIe slots when another is in use.  Do all cards work when in a slot?  If you have only one card, and it is on the riser from the main 16X PCIe slot, does t work?  Check, if the riser does not work from the main 16X slot with only a single card, it is a bad riser.

The other thing, if your power supply is weak, the system may be unsuitable for that 3rd GPU.  Risers and worn out or low wattage PSUs are often the cause.  If your PSU is good, just swapping risers will often fix the problem.       --scryptr

thanks for your complete answer!!

I have tried riser with one gpu on main 16x slot and not working.... all the cards work when in a slot and I think wattage is enough for this 3 cards,  because according to my measures, 2 cards and computer consumes less than 400w and my psu is 650w gold

so i will return the riser and buy another one. thanks!!

equihash core intensive? I thought it was memory intensive, I have 1070 and have tried also 1080ti, and I leave core clock stock settings and memory as high as possible, also reducing power limit

is not correct that?

no. memory plays a minimal role

I have similar problem , my miner crushes a lot , sometimes it runs for more hours , sometimes it doesnt.  Also my rig starts lagging a lot .
I have windows 10 x64 , latest updates ,  4x 1060 3gb , 1x 1080 ti , 1x 1080 .  I've left all cards to 80% power limit , +100 core , 0 mem .  Also miner throttles a lot , Speed starts to drop off a lot . Any ideas , possible solutions ? Also tried to lower intensity and I left it at --intensity 50 at the moment.

Please state your source because from the begining of zcash I have read that it is memory intensive.

https://z.cash/blog/why-equihash.html
Equihash is a memory-oriented Proof-of-Work, which means how much mining you can do is mostly determined by how much RAM you have. We think it is unlikely that anyone will be able to build cost-effective custom hardware (ASICs) for mining in the foreseeable future.

so the overclock I did is wrong? I put -60 core clock +73% power limit and + 625 memory clock

however, this could be valid for mining eth? which settings should be good for zcash and a gtx 1070?

Equihash (as used by ZCash) was intended to be memory-intensive, but turns out to not be nearly as much so as the original creators probably intended it to be - it's DEFINITELY not as memory-limited as the algo used in ETH mining.

 In practice it wants a lot more core clock than memory clock when you're overclocking cards to mine it.

 Your -60 core +625 memory would be a good starting point for ETH mining, if it's stable.

Hi, I want to know if anyone has a (bat) to use slush pool with EWBF 0.3.4b THANK YOU =)

Isn't it the standard .bat except using userName.workerName instead of a wallet address?

[jocarugo]

I have this but it is misconfigured (Miner.exe --server us-east.zec.slushpool.com --user t1K1PKJ8LBurBy2y8yT5mtrE9euuVtjbiQj.PCMINER --jocarugo --port 4444 --allpools 1 --pec). And I am something new at the moment and I feel a little difficult for this.

miner.exe --server us-east.zec.slushpool.com --user username.worker --pass x --port 4444 --pec

That should be all that you need to get it running.

I think you also have to register the worker in your user control panel before they will allow the connection.
