Haven't experimented too much with changing the clock speeds yet, I just used default settings from my ETH mining, so switching between the two coins is pretty much effortless. The pleasant surprise was this "test" rig was drawing ~290 watts at-the-wall while mining ETH and this has dropped to 199 watts mining ZCash. This suggests the ability to potentially push the clocks higher with this algorithm.

With the kernel im getting 14 sol/s on 290 give it a shot.

I got same results (15sols/s on 290 with 'threads'=11264 in config.txt file). It seems this miner a bit faster others on RX470/RX480, but don't show good perfornance on R9 2xx.
But it's not a final release!

It will not work with suprnova stratum?
Just do not want to install ZCash wallet.

Can't do before mainnet launch.

can help me?

I get the same:(made sure cards were default settings)

Great work how u can get 8.5 Sol on a Nvidia 750 Ti i get only 1.5Sol

Thx in advance

How difficult would it be to make a Cuda version for nvidia cards?

Try lowering your worksize and/or threads. I got that same error when trying to push my worksize up.

What dependencies needed for this?

CUDA is per definition for nVidia cards.

[ShopemNL]

Weird, the first card seems to be slow (only 2 sol) rest is 14 sol.

Is any way to get an address without installing Ubuntu, compiling wallet etc?

Haven't experimented too much with changing the clock speeds yet, I just used default settings from my ETH mining, so switching between the two coins is pretty much effortless. The pleasant surprise was this "test" rig was drawing ~290 watts at-the-wall while mining ETH and this has dropped to 199 watts mining ZCash. This suggests the ability to potentially push the clocks higher with this algorithm.

A little update.

I have been playing around a bit more, it crashed immediately (console windows closes) if I push the memory clocks much more. However, it loves the core clock increases. I got my core set at 1300 MHz now, or 50 MHz past default, and I am cranking along at:

Work received: height=1301 diff=8694.1578 latency=156ms
[GPU 0] T=-1C A=-1% sols=18.712
[GPU 1] T=-1C A=-1% sols=18.068

I also tried adjusting the worksize and threads a bit as well and it seemed to have a slight improvement moving the worksize down to 192 and increasing threads to 11264, but not enough difference to be definitive yet.

It seems memory bus/frequency is a far more important metric than clock-speed. Try cranking up the memory as high as you can, and downlclocking your cores.

For testing you can just use the address in the config file (that's what I and it looks like a lot of others are doing) but for mainnet launch you will need your own address. Depends on if an exchange trades on day 1 or not if you can use that for an address, but it is probably worth your while to download and compile your own wallet.

Remember this is launching with a slow-start, so even if you get in a few days later you will not be missing out on a lot of coins as that was pretty much the intention to give everyone time to get kinks worked out etc. before full block mining appears. I am sure within a week or so there will be Windows wallets available and maybe even sooner you will have exchanges with addresses you can mine to.

Whoops I meant for nvidia.  As this miner is opencl, right?  But it's based on Cuda code?

I would assume so. But then again, you know what they say about assumptions.

First of all, thanks for this miner.

nice! clocking ~18Sols/s on the same R9 390X that does ~22 using my own brew. your miner has one major advantage though...it actually comes up with solutions that are accepted by the pool
