Open Source ZEC (ZCash) GPU Miner AMD & NVidia (up to 45 sol/s on RX480)

[IOTUSA]

This is great.. we have a running gpu miner... so better this than a cpu miner

Except there is an optimized CPU miner that pulls 30/sols out of a single Xeon CPU

Which optimized CPU miner is that? Where did you get that benchmark for Xeon CPUs? Most i7 don't go over 10 H/sec

A Xeon can have up to 22 threads though vs the 8 threads of and i7

Doesn't matter. CPU mining doesn't scale well at all beyond 4-6 cores, and hyperthreading does more damage than good cause it just fills up memory channels. Memory bandwidth and frequency is far more important than cores.

Anyone tested the mining speed of AMD 7950 ? Does it worth testing?

[DarKSm0ke]

yes similar here.

I guess the pool is receiving a lot of requests recently due to everyone testing out the miner.

I am sure it will be resolved soon.

Thanks for sharing this miner with us!

7950 - 7.5 sol

For GPU mining to even be viable vs. closed source and optimized CPU this has to double or triple. That said, it rocks that we have a working implementation, even with performance being lackluster vs. the optimized closed source.

[Marvell1]

Gnoli miner and the Toomin miner do around 17.5 sol on a 480x and 22 sol on a 290x respectivley

I don't know where you're getting your numbers from, but we are much faster than 22 Sol/s.

Sorry I watched the youtube video demo , must have read the results on the screen wrong no disrespect meant.

It seems you are getting over 40 sols on your 290x cards.  - fastest implementation of of EQuihash so far out there.

CPU wise only .60 sols per core - which is inline with the slower CPU implementations of course this is not your focus.

Yeah if they add the TROMP solvers which have already been implemented in the Nicehash binary they should be able to at least double the current perfomance

[DarKSm0ke]

Did anyone already tried on a multiple GPU rig?

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

We should be able to reach higher performance soon, hopefully.

@darksmoke works fine with multi-gpu

[joniosbra]

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

same question

My rig r9-390+rx470+rx470+7950 = 42 sols/s

[IOTUSA]

Anyone here have a 390/390x to test with? I am offsite and can't run my own tests right now.

MSI r9 390 = 10.6 sols/s

nope... 10.3.... with default.bin....
is there a new bin for the card?

edit: found it .. using the r92XX that was in a folder!!!!!
15.3 sols

Very odd considering: 14 sol/s on 290

I think the recommended drivers are the amdgpu-pro 16.30

Pool mining:

Miner uses custom binary protocol first time implemented in xpmclient (Primecoin GPU miner). Working pool instance: http://coinsforall.io/#!/coin/ZCASH

To start mining:
 - Put your Z-addess to config.txt (need ZCash client installed, online wallet or exchange with ZCash support):

server = "coinsforall.io";
port = "6668";

# Your ZCASH payout address (z-addr)
address = "zthTb2ToG5kuAc11Ni6NxoYjoxQdEr2XvST7XEdLvmHG9k7kotEcwYCaAn1SH4zRdPoXn9kNeFm8CQo k9SNtNgn8d9WcdTK";

 - Configure your GPUs (edit corefreq, memfreq, powertune and fanspeed parameters)
 - Run zcashgpuclient in Linux or zcashgpuclient.exe in Windows
 - Put you address to 'Your Address' field on web site for monitoring workers and payments

Pool system: PPLNS (Pay Per Last N Shares); accounting procedure uses all your shares received during last hour.

Pool now configured for public ZCash testnet until 28 October when mainnet starts

Awesome news! Thanks for this!
