Hi,
Thank you for making this miner.
I would like to know if your miner supports multiple instances. I have 12 cards and would want 2 instances of your miner running simultaneously with 6 cards accessible for each instance. Reason for doing this is to increase probability of getting shares.
Could you comment if this is possible, how to achieve it and if it will yield the benefits I stated?
Thank you and more power to you and your team.

Yes, you can do this and it is quite easy. The first step is to have two copies of the PhoenixMiner folder. Then add the command line option
-gpus 123456 to the command line of the first miner (or in the config.txt file if you are using config.txt file instead of directly adding command-line options). This will limit the first instance of PhoenixMiner to the first six cards of your rig. For the second instance of the miner use the option
-gpus 7,8,9,10,11,12 and it will use the other six cards.
If you want to use remote monitoring, you have to add the option
-cdmport 3334 on one of the instances (first
or second) because they cant both run on the default port 3333 for remote monitoring.
As for the more probability of getting shares, we don't think that it would make much difference but you can use one half of the rig to mine on one pool and other - on different pool and compare which works best for your. Or you can even mine different coins.
Hello Phoenix, is there any scheduled date when version 2.7. will be released? I had to switch back to Claymore's miner because of that bug when during Devfee session the voltage parameters of cards are reset.
I really like your miner as it has better hashrate performance and lower stale shares on Ethermine.
Also stability is without any problems..mining 2 weeks and no sigle crash.
We will release an early beta tomorrow or the day after tomorrow (depending on how the internal testing goes). The "seemless" devfee switch is already undergoing testing and works quite stable but the hardware control options are nowhere near completion, so we will probably release a 2.7a versions without them but with all the other new features first.
How to use -gt (GPU tuning, what does it do)? I dont seem to find any value that would make a difference.
There is quite small difference unless you go to really high gt values (above 30-40). Also, give it at least 30-60 seconds for the hashrate to "settle" after changing the gt value before moving to the next gt value (you can move by 10, for example from 15 to 25, then wait one minute to see what the hashrate looks like when it stabilizes, then repeat and so on).
Running HWiNFO v5.72 in the background I lose 1-2 mh/s ... it's just me ?
Yes, this is normal, and the same effect can be observed with GPU-Z when looking in the sensor tab. The reason is that the ADL library is not thread-safe and the sensor readings can't be read in parallel, which slows down the driver, especially when all available sensors are read every second or so, which is the normal mode of operation of these programs. If you want to keep them in the background, make sure that the frequency of reading of the sensors is not too high (for example once every 10-30 seconds should be fine but once every few seconds is too often).
The -gpus command does not work. I cannot mine with only specific gpus. Any suggestions?
Could give us some specifics? How menu cards you have, and what command line you are using? Note that the -gpus option GPU indexes start from 1, not 0 like in the -di option. So, if you want to use only the first three cards, you have to use
-gpus 123 or
-di 012.

Hmm, this is something new. So far we have seen this only with AMD cards. Would you mind telling us what program you are using for setting the clocks and voltages of your cards?
