Hi and thank you for your interest.
You should not count megahashes on dashminer. Dashminer works with %. Period.
R9 290 is about 100% speed. That will give you 0.26 DASH + daily bonus. Usually, this is somewhere around 0.0038 BTC per day for a single R9 290.
You should compare this daily income with the income that you're getting from other pools and make a decision. Factor in the power consumption / noise / heat.
dashminer.com is not for everyone. I can see that you need to keep your system cool and you only have 1 card... So this pool is probably not for you.
Serious miners have at least a dozen cards, open case systems with additional airflow, etc. They count watts that they pay for and are very sensitive to the daily income they're getting. dashminer.com is targetted more towards such miners.
Thank you!
Everyone has to start somewhere. I am in it to make money, not just burn electricity. But, I am not rich, so I have to add to as I am able. Matter of fact, I just recently acquired a 290x and a water cooler for it. SHould be here in a week. I intend to point it to the dashminer server, since I will be able to run it hard without heat becoming an issue. And, if my upcoming software release goes well, i will have the cash to buy a few rigs full of Fury X's So, I could potentially go from a single card miner to a small gpu farm in a couple months. My point is, I like to plan ahead. I need to know everything, so I don't get caught in a bad way.
And, just for the sake of giving dashminer a sensible trial, I have tweaked the settings (via the conf file), and am running my 290 at 59C-60C for at least 24 hours. I figured I should at least give it a full run to see how the payout compares to what I am getting at Xpool. With the settings I am using now, I am getting about 64%. Doing it this way, i can do a direct comparison based on power consumption vs payout, since I can't do it via Mh/s.
When I really have time to focus on it, i will probably start looking in to streamlining the mining software....since I am a programmer.
Also, while I am at it, to show I am not just trolling, I will post my bat and conf code, so anyone else wanting to run a bit cooler are able to do so easily.
My "sgminer.bat" file contains:
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
sgminer.exe
pause
My "sgminer.conf" file contains:
{
"pools" : [
{
"url" : "ny",
"user" : "my_user_name_here",
"pass" : "my_email@my_email_provider.com"
}
],
"device" : "0",
"xintensity": "64",
"gpu-threads" : "4",
"gpu-powertune" : "-34",
"gpu-engine" : "947",
"gpu-memclock" : "1250",
"temp-cutoff": "70",
"temp-overheat": "65",
"temp-target": "60",
"auto-fan": true,
"api-port" : "4028"
}
This is what I use for my r9 290. When I add the r9 290x in a week, I will have to change the conf file, but not the bat file.
The changes to the conf file will be to the following entries (everything else remains the same):
"device" : "1",
"xintensity": "64",
"gpu-threads" : "4",
"gpu-powertune" : "0",
"gpu-engine" : "1100",
"gpu-memclock" : "1250",
The reason only the temp parameters will not be changing is due to the watercooler i will be using. The NZXT Kraken G10 and X31 unit.
The temp should stay well below 50C, but this cooler does not water cool the vram. That is still air cooled. So, no OC to the memory,
and no increase in the voltage...although the voltage will be able to remain at the baseline 0 level.
Anyway, hopefully this will help someone else wanting to try out dashminer, but not wanting to let their system run hot.
