Beware on using unknown firmware posted by newbies there are possibilities that the firmware is compromised.

Anyway, you can overclock and change the frequency without changing your firmware by following this guide https://bitcointalk.org/index.php?topic=3239820.0
and increase the fan speed by following this guide https://bitcointalk.org/index.php?topic=2690140.0

how do you know it's 7%? any way to check this? 1.5~7% is a huge difference.

I really like the firmware, no complaints works very well. Job well done to dev team. Only problem is, and I'm no mathematician but dev fee seems much higher than 1.5%. Before taking steps to mass deploy, I'll need to figure that out.

Make the calculation as in the picture, or measure per pool during the day

how do you know it's 7%? any way to check this? 1.5~7% is a huge difference.

you can simply monitor the hasrate on the pool side, a graph is usually presented. something like this



those ugly green arrows point to time periods that the dev fees were taking place. while this is not 100% accurate because a few other things aside form dev fees can show the same results ,but overall this is a highly accurate method to determine dev fees with little to no efforts.

take 24 hours of mining , sum the total "flat" time periods and get the percentage by doing a simple calculation.

do this for the first 24 hours if fees are higher than what you willing to pay > ditch it
if fees are fine , make a longer duration based test. maybe 72 hours. some devs are smart liars, they don't take the fees straight away,so you monitor the firmware for a few hours, and you say waw , this is it , only then they start to screw you , you just need to dig a bit deeper to be 100%.

the kernel log can also show you the results, but using the graph of your pool is usually the easiest way.



paying 7% for dev fees can be very stupid. simply because

assuming you went from 14 to 17th , then that's about 20% more hashrate, impressive right? but take a look at the power cost , it has increased, and you are paying 7% of your net-profit before paying for power. so at the end you might end up making just the same profit but risking your miner to failure by pushing it to it's limits.

That^^ plus the fact that IF the miner finds a block during the dev mining period you or the pool obviously do not get credit for the block -- the developer does. Just something to keep in mind...

almost 2% is not small. oh. Not bad, he clearly raises on the commission. (Developer)  Roll Eyes

it really depends on the miner and the market condition, sometimes paying even 5%/10% of your profit  MAY still benefits you. for example the D3 by bitmain has a terrible firmware , therefore usually a custom firmware was needed , and the known custom firmware by then had less than 2% fees which was very reasonable and overall profit increased even after paying the fees. however in most cases the stock firmware does just fine, also one thing that many people seem to be missing is that when dev fees are stated at say 10% , it does not mean miner will mine for 2.4 hrs straight for the dev pool and then you get the all of the remaining 21.6 hrs to your pool, it doesn't work this way simply because

1- The dev fees are time-based, they start the count from the time the miner switches to their pool till the time it swihces back to yours, there is gap in between as it's never instant when cgminer switch pools , you are looking at a quite a bigger loss as you are the only who bears those switching periods, they are small but when summed up, the became reasonably questionable.

2- The dev ensures he get's his fees asap, so assuming it's 10% , they will try to get 10% of each hour, and not straight 2.4hrs. therefore assuming you start your miner, 2 mins on your pool , then 6 mins (10%) to dev pool , then cgminer restarts for whatever reason , 2 mins on your pool 6% to his pool again !

total time for you = 4 mins , for dev = 12 mins.

of course this case will not apply 100% of the time, but the possibility is always there, dev has the right to do it this way to prevent people from cheating,but they usually don't tell you the full story.
---------------------------------------------------

I tried a few custom firmware, i usually divide my miners , split them into 50% stock fw, 50% custom, let them run for a few days and them make my calculation.

i used the method mentioned above as well as Wireshark and other network tools to monitor exactly the time my miners were mining on dev pool vs mine.

there is almost 0 chance you are going to lose only what the dev states , there is always a bit to a lot extra .

so i advice everybody to do the math before trusting and settling down on a custom firmware.
