Thank you very much.
Just another GTX1080 user here to report performance around ~90 Sols/s after overclock. Thanks for the miner though, it’s the best performing so far.
nicehash reports quite a high reject rate:
1.81 Sol/s (2.70%)
Target: 1.81 Sol/s
[09:22:21][0x0000xxxxxxxxxx00] stratum | Rejected share #81 (Share above target.)
with silentarmy I had exactly 0.
I have reject rate around 1-2%.
So from 120 sol/s, 2,5% is dev fee and 1-2% is rejected.
If we take that as 5% loss, you still come from 120sol/s to 114 sol/s.
Silentarmy gave exactly 88sol/s for me. Not sure if there was any fee or not, but you can still see that this miner is better because you are still making around 25 sol/s more than before.
At least that’s how it is for me.
But I got around 0,5% rejected rate with silentarmy.
Not sure if there is any miner that is 100% buggfree.
Can’t wait to see new version and new optimisation for GTX 1070 cards. I think it can get up to 150 or even 160 sol/s.
Right now it’s using around 80-85% power, so it can still use like 20-30% more (if overclocked).
@zcminer-dev are you working on any new updates and optimisations? Do you think you can fully utilise GTX 1070 cards?
Just for a laugh I thought I would try this on a 750ti, didn’t expect much of a jump over the eqm nicehash miner but yeah I was wrong. 750ti now doing 34.5 sols up from 24 sols. Original zcash miners got 15 sols with this card. Hell of a gain!
Morning!
@chronosek
Minimum cc3.5 is due to some operations I am using that do not work with cc3.0. Then again cc3.0 cards might be very slow anyways.
@Holy
That sounds good 
The drop might be due to the card reducing its boost clock when reaching higher temperature.
@Melthdown
Just add a zcash address and a pool to start:
zcminer -l eu1-zcash.flypool.org:3333 -u zcashtaddress
@rekoil
Maybe try the ‘-s1’ option as Holy said before.
@bugmenot
The rejects usually happen due to outdated shares (pool has already sent a new job or target in the meantime). You should be able to reduce rejection rate a little by using less mining threads, but this might also reduce Sol/s. I’m currently working on rewriting my mining code, not sure how fast I can make it. 160 sol/s would be nice.
@darky1
Nice to hear
@zcminer-dev thx getting 106 soils/s with strix gtx 980 oc +200 core +430 memory
Small update to my other post. Currently 0 loss but speed has dropped from 34.5 to 33 exactly.
Looking forward to trying this on a clocked 980ti later. Currently have it running at 1500mhz core so might be good!
nicehash released updated eqm, 115 sol/s for my gtx 980 … will be war between devs?
war would be kind of nice. Get these 1070 cards up to Fury speeds, 170 sols would be great!
Can you link the miner? whant to test it
link in their official thread - Miner- Nicehash EQM
Unrealistic if you ask me.
160 is the upper limit for gtx 1070.
Anything beyond that would need custom BIOS and tweaking.
-s1 has basically no impact. In fact, seems to lower output slightly.
Strange things happened after upgrading my graphic driver to 375.86
My speed dropped from 100 Sol/s to 32 Sol/s.
Not only happen with zc_miner. Silentarmy and eqm also got affected.
Weird.
Ok forget it. It’s a driver problem that limited my memory clock @ 400MHz…
Can I use my CPU to mine as well? Or is it GPU only?
Could it be that the GDDR5X memory is just being badly utilised by the miner? I mean, each memory fetch returns twice the amount of data, and the memory is running at 62.5% the speed of the GTX1070 (slower, but greater than half so in total there is a 25% increase in memory bandwidth, just accessed differently). So logically it would require fewer fetches to return the same amount of data, and thus require fewer clock cycles. Does that make sense?
