Firstly, big thanks to Claymore for getting this great miner out to everyone!  I know you mentioned that you still expect you can get better rates down the road but I think I am not alone in appreciation for you publishing this version now so we can mine more efficiently than other options currently available!

I have only read about half of this thread so sorry if I am repeating anything here but I did have a few observations and questions that I wanted to post.

- I have 4 MSI RX 470 4GB (strap 1500 mod, overclocked, undervolted) averaging between 40-42 Sols/s each using your miner. This is a vast improvement over the 13 I was getting using nicehash the last few days, so really appreciate the extra sols!

- I noticed that the power draw for this miner is much lower than your ETH Dual Miner.  Even just solo mining ETH my rig was using ~625W at the wall, while your ZEC miner is only using between 400-450W!  This of course increased the profit margin over ETH mining even more, which is great, but I have a question about the power consumption.  Is it just that mining this coin is inherently less power-consuming than ETH?  Or, does the much lower power draw mean that there is still a lot more headroom to work towards increasing Sols/s even more?

- Finally, after running your ZEC miner stably for about an hour this morning, I launched nicehash miner to use only its CPU ZEC mining function. Unfortunately, almost right at launch, it cut the Sols/s rate in your miner by about 25% on each GPU.  Then after about 5 minutes, it crashed my system. Then crashed again after reboot, so I haven't tried it again.  This seems a bit weird to me since I have used other CPU/memory intensive programs like Claymore Crytponote CPU to mine XMR and plotting & optimizing BurstCoin plots on HDDs and neither affected your ETH GPU miner.

Normally, I wouldn't even bother about CPU but this rig has an i7-6800k that was pulling 23 S/s, which equates to more than half of a GPU, so I hate to waste it idly.  Anyone here been able to CPU mine ZEC with NH and GPU with Claymore successfully?



Did you set your nicehash miner using -t 6 ? (6 = 6 threads)

Nope... thanks, I will give that a try and see what happens.  Out of curiosity, how exactly would you do that?  I know how to make that kind of change like in a .bat file (such as exists in Claymore's work) but I only see EXE and DLL files in the NHM directory.

i have those and works fine. I tried to mark them on paint but that fucked up the resolution (no idea why). i hope u can see them the txt and bat file.

Thanks very much! I can see it fine when zooming in. So... I checked that directory and I do not have that .bat file in it.  Did you just created that yourself and use that to launch nheqminer in a command window (meaning that you not not use the GUI)?  Or, do you create that .bat file, then launch the NHM GUI exe and that will pick up this new command?  Thanks again, I am still learning this stuff Wink
U launch it thru the bat file. (Which u make it by urself)
