Re: DashMiner.com - BTC & DASH multipool for AMD GPUs. Fast kernel and custom software. Extra profit
I have a bit of a problem. Hopefully we can get this issue sorted out.
So here is the deal. I run sgminer 4.2.2. Just open source stuff that I have found via forum crawling. I have a single r9 290. I read that dashminer uses x11 as one of its algorithms. The reference given was found here http://dashminer.com/stats/. As it states, the reference r9 290 card crunched out 4.84Mh/s, and they are using this as a sort of baseline reference for their % value scale. No problems so far?
Okay, here is where my problem kicks in. When I mine on x11, I maintain a stable 6.1 Mh/s. The issue is, the dashminer software is overworking my card, and getting worse performance.
When I am hashing x11, maintaining a stable 6.1 Mh/s, my temp never reaches 60c, because I set the power limit to -38 (yes, that is negative 38). I am using much less power, and increasing efficiency by running cooler. Yet, my hash rate is about 25% higher. I snapped a couple screenshots just for a quick reference.
My normal mining on x11:
My mining with dashminer:
As you can see, I normally run at a cool ~58c. When I run the dashmining, I was pushing 73c, and still only hitting 92.74%. So, I am burning more power, and dropping efficiency from heat...plus I am running a lot slower in MH/s. I tried dropping the power limit down to -38, like I normally do. When I did that, my % value droped to about 50%-55%, and the heat problem still did not completely go away (stayed around 63c-65c). Obviously that is not realistic. If I were fine with running my card hot (>70c), I could set my powerlimit back to 0, and then my normal x11 hash rate goes up to around 8 Mh/s.
What gives? I want to try out the dashminer pool, but I need to figure out why I am having this issue to make it worth the switch.

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!
