Same here!  It would be interesting to map out what algos work well together.  A quick search came up with this article:

Which mentions a nicehash fork that includes dual mining:

Looks like there might be some interesting possibilities/ideas there to use within zPoolMiner?!  

I ran into the same thing.  Was mining phi but receiving no payouts.  I looked at the pool stats and it had been over 6 hrs since anything had been discovered and looked like the MH/s rate of the pool was in the dumps.  something like 2-3 day TTF for the block.  I unchecked PHI and things went back to normal.  

I think perhaps it benchmarks one card at a time?  So you have to wait on the first before the second starts?  I ran into the same thing and ended up just benchmarking them separately using the check boxes.   

Hope things are going well today!  I have had good success with the KlausT ccminer for neoscrypt as well.  I think neoscrypt in general hits a sweet spot for the 1070 mining power as my 1080 ti is only ~ 27% faster on that algorithm at ~50% more power.  Supposedly it has something to do with the GDDR5 (1060 and 1070's) vs GDDR5X (1080 and 1080 ti) memory latency, GDDR5 being more responsive.  All that being said, I guess profitability still just depends on current market prices. 

At the moment I'm keeping them in BTC and exchange myself at a later date.  I also had the change to nist5 for a bit yesterday but it worked properly for me.  I've had it stay on 0 hashes for a minute or two but I believe that is due to either the API being worked on momentarily or the miner waiting for data from zpool.   

Oh nice.  I just got two ti's with the same thought on resale potential.  The prices right now are crazy!  I was lucky to find a couple in stock for normal-ish prices, but it took a lot of looking...I think the price jumps/news in December will bring in a bunch of new hobby miners.  

I'll keep an eye on my setup and see if anything else happens.  I haven't had a change over to the dev address since the first one.    If you can't find anything, I can try out your 5 minute dev version (if you want)  and see if I can recreate anything.    

oh nice!  that will speed up testing a bit.  For what it's worth, I was thinking it might have to do with the fact that I manually stopped mining after the first card switched over and then restarted it.  So the initial change worked as you expected (only 1 card) but the restart during the 12 minute period affected both cards starting but only the 1 card again when time was up.  

No worries! Thanks for taking a look.  Don't stress too much...I can support the cause a bit   

Just sent over the log.    I do have 1 1080 ti and one 1070.  Both of mine ended up switching though.  Perhaps because I cycled the miner mid change?   Thanks for explaining how the schedule works.

I had something similar happen.  I was watching my wallet on zpool and noticed my 1070 nist5 gpu had dropped out.  Looked in the log and saw that I had been switched over to the dev fee wallet as described in the first post.  

Cryptominer, would you mind just clarifying how it is decided when this switch is made/the fee timing schedule?  I'm not worried about it, I just think there might be an issue with my second GPU not reverting back to my wallet automatically  (after ~30 minutes on the dev wallet I stopped the mining in the GUI and restarted again.  It then switched back to my wallet.   I can send over the log if you would like to see it.

So far so good with everything else on my end.  Thanks!

On windows 10 with an XFX RX 480, 17.12.1 driver, I am not detecting any usable devices on 1.9.0.0.  I checked the settings and it should be looking for AMD devices unless I need to change something else?  Perhaps it's due to the stock driver vs the AMD crypto driver?  It's not my machine and used for gaming, so I would probably hear about it if I started changing drivers around...

First of all,  thanks for all your work with this!! I think it will be very helpful.

Am I correct in thinking that neoscrypt hasn't been added back into 1.9 yet?
 
I also have access to an rx480 if you would like me to run a couple test with it? (I think you mentioned you just have 1080's?)
