With AMD 400 and 500 series cards, how much are you undervolting for zec/zen mining? and are you underclocking the core too like with eth?

I run Anorak's powersave BIOSes on my 570s and 580s.  I haven't tried the other BIOSes with ZEC but I should give it a try.  I suspect it will be the same situation as mining ETH though, not worth the extra power cost and heat.  I also suspect you still want to underclock the core when mining ZEC.

What is wrong with suprnova? I am mining ZEC and earnings dropped from 0.3 to 0.05 per day?

I noticed same thing. $1 dollar per day not including electric cost with a 1080 Ti mining on suprnova. I lost money mining zcash. Something is up with the pool or difficulty is through the roof

That is insanely low.  My 1060 does better than that.

Just compare pools hashrate suprnova - 8 Mh/s, flypool 224 Mh/s.
At suprnova was found only 6 blocks for last 24h.
So factor of luck have a big influence on your daily income, todays it's only 6 block, if tomorrow be 10 and you will get +67%.

A little help would be appreciated.

I switched recently to mining Zcash from dual mining ETH & SIA. The problem is I can't seem to get maximum from my cards. I have a rig with 4x1070. From what I have been reading they should be able of producing 450 sols each. I get maximum around 420 from 2 cards and 390 from other two.

Cards are ok because all for of them were around 31 MH for ETH in dual mining (450 sia) no problem.

Any advice would be appreciated. OC settings: Is memory important or core or both? Which miner to use for best hashrate? Am I missing something obvious? At the moment I am using nanopool and EWBF's CUDA Zcash miner.

The OC settings are different for ZEC and ETH.
The core OC is the important for ZEC.
I have 440 Sol/s per each 1070 in my rig.

Dual mining uses every idle gpu power, so it's power consuming.

Is their software out there that will mine with both AMD and Nvidia from the same executable.
a bit like the claymore software.

nope, just start 2 miners, one for AMD GPUs and another one for Nvidia GPUs. There shouldn't be any problems, I'm doing that by myself.

I have 440 Sol/s per each 1070 in my rig.

My 1070 performs poorly.  It rarely gets above 400 H/s on ZEC and usually runs about 340-360.  Terrible.  I've tried all kinds of OC settings.  It does well on ETH though.

The 1070 gets unstable and stops at +175 core OC.  Should I OC memory as well?

By comparison, my 1060 does 290 H/s or better most of the time.

I am thinking we are making some stupid mistake. I can't believe that there is so much difference between 1070 cards. Can one of you with 440+ sols share his setup? Which miner, pool, and oc settings including undervolting are you using?

So the problem with my 1070 turned out to be TeamViewer.  When TeamViewer is running the hash rate drops a lot.  I get over 430 H/s if I close TeamViewer.  Same thing happens with VNC.

I don't know why but that's what it is.  I don't even have a monitor plugged into any card.

 Underclock core on ZEC/ZEN = BAD thing, the algorithm is not severely memory-limited like ETH is.

mining with 1070s on ewfb and afterburner using +100 core, +500 memory, 85% PL, and lock volt to .963. get 450 sol on average. can fluctuate 440-470.

Recent experimentation on my Aorus GTX 1080ti came up with the following Afterburner settings for "fairly efficient" mining.

 TDP 75% (188 watts more or less).
 CORE +150
 Memory +100

 resulting in right around 700 sol/s



 I do wish folks would stop just posting "TDP %" figures, as they are MEANINGLESS without the card involved, or what the actual WATT figure ends up at.
 This is PARTICULARLY true for GTX 1070 cards that can range from 151 watt factory TDP (all FE cards, many lower-end cards including the Gigabyte ITX/Zotac Mini/EVGA SC Black/MSI "Aero" ITX) to 240 watt factory TDP (the MSI "Armor" model that has 2 PCI-E power connectors).

 It's ENTIRELY possible for my "80% TDP' figure on that MSI card to be HIGHER than YOUR "100% TDP" figure on many other GTX 1070 cards or even some GTX 1080 models (which start at 180 watts).

Superb dude. I am not involved in mining big. I am research about mining and finally now arranging to go with the 2 altcoin mining rig one is for eth and one is monero. I will go with Nvidia 1070 TI cards 6 numbers in each rig. Will it profitable to mine Zcash with the specification I said. SSD would 64 GB and 8 GB RAM.

Some incredible mining profit spikes on Zcash since last night but they only last a few minutes.  My rig makes about $8-9 per day the last week mining ETH/DCR or Zcash and last night Zcash spiked to $11.50 for a few minutes.

I'm even mining it with my AMD cards.  I did not realize how little power 570s and 580s use to mine Zcash compared to ETH and ETH/dual mining.  My 4 AMD cards are using almost 300W less when mining ZCash vs ETH/DCR!  That works out to about 75 cents per day saved on power and everything runs much cooler.  So now I am factoring that into my decisions about what to mine.

Is that $8-9 pre or post-electricity costs?

That's gross profit, electric is about 20% of that.

Since Zcash has dropped back to $200s in the last week I've gone back to mining ETH on my AMD cards.

 GTX 1070 is overpriced at current pricing for ETH mining - you'd do better to build an ETH mining rig around AMD RX 470/480/570/580 cards now that they're commonly available under $300 again.
 SSD is a waste on a pure mining rig - I'd go with a low cost hard drive or a USB flash drive instead.
 8GB is overkill for a pure mining rig but does offer some future "room to grow", and it's not all that much more expen$ive than 4 GB any more.

 Yes, your planned rigs SHOULD be profitable on ZEC mining - as long as your electric cost is not crazy-high.
 I CAN'T say if it will achieve ROI though, way too many variables like "future ZEC pricing" that I don't know and NOBODY can predict, and I also have no idea what your electric cost is like.
