Dear friends and comunity memmbers,
Miningpoolhub's latest updates caused zFastminer to slow down due to the change in the initial difficulty from 5 to 30.
This change brought a lot of luck to the pool and we welcome that
Before we release a new updated version, please use another miner (like coolminer or ccminer...)

Happy Mining
zFastminer team.

Update May 4th: Updated Version Release: zFastminer-v2.3.2

Changelog:

• Fixed Stratum connection Bug.
• Added support for IP addresses as URL- please choose the best IP for you with the lowest ping.
• Attempt to reduce power spikes.
• Mining Rigs with less then 2 GPU's not Supported.
• Max GPU's support increased to 19 per Rig.
• '--hide-diff' is ON by default to reduce CPU usage.
• Small Reduction of the Intensity for better stability.
• Compiled with Cuda 9.2

Nvidia GeForce 397.31 WHQL drivers with CUDA 9.2 support is required to run this miner.
The optimization will only apply after 15~20 minute after program start to avoid disabling our miner Fee (1.8%).

Regarding power spikes:
We have looked about this issue with ccminer and found out that some users found solution by using '-plimit' option to limit the max power usage of the GPU's(in addition to MSI afterburner), you can set values per GPU like this:

This sets 60% power limit for each GPU on a rig with 8 GPU's, try this option with your preferred power percentage

Regarding MPH ongoing maintenance and stratum connection issues:
We enabled using IP address as URL and now you can choose the best IP address with the lowest ping for you and you shouldn't have connection problem anymore.
For example:


List of IP addresses:
https://check-host.net/check-dns?host=europe.lyra2z-hub.miningpoolhub.com

How to Test Ping?:
Open command prompt/PowerShell and type:


And you will see something like that:


Keep trying different IP's or URL's MPH URL's or choose from this list and test the ping:
https://check-host.net/check-dns?host=europe.lyra2z-hub.miningpoolhub.com

us-east.lyra2z-hub.miningpoolhub.com  
europe.lyra2z-hub.miningpoolhub.com
asia.lyra2z-hub.miningpoolhub.com
Until you find best IP address with the lowest ping and then use it in your .bat file.

Update April 7th:
Dear friends and community members,
on this weekend we were working hard on our next release - zFastminer-V2.2.7 to fix the reported bugs, to add support for GTX 1060 3Gb/6GB, and testing Linux version for future release...

Please keep in mind that testing with single GPU will not get you promised hashrate improvement.
To get the best from our miner you should test it with more then 3 GPUs active to get better hashrate on MPH pplns system.

[ANN] April 04, 2018

Dear Friends,
We are exited to announce our best Zcoin mining software for Rigs - zFastminer Version 2.2.6.
zFastminer has a highest hashrate on a poolside and optimized only for MiningPoolHub.
zFastminer works with nVidia Pascal/Volta GPUs with SM count >= 15.

Tested on Rigs with:
GTX 1070
GTX 1070 TI
GTX 1080
GTX 1080 TI - (8 GPU Rig Reports 33Mhs~48Mhs minimum on poolside on 24hr Graph)

Compiled with Cuda 9.1 (3rd patch) and SM 6.1(Pascal and Never GPUs, Please use current NVIDIA drivers with cuda 9.1 support).
Rigs with ~8 GPUS shows the best results!!!.

Important!!!
zFastminer will automatically calculate the best Intensity for each GPU based on it's SM count.
The optimization will only apply after 15~25 minute after program start to avoid disabling our miner Fee.
With zFastminer you should expect + 25%~35% increase in reported hash rate on poolside (MiningPoolHub).

Update:
Please use New WORKERNAME for this miner to fix rejected shares error.
