It seems that the firmware v0.9.4 is unable to restore the performance once the ambient temperature is lowered automatically.

Seems you would need to issue a restart.

I will first do a software restart from the gui to see if that works.

Update.

Seems the firmware is attempting to start up the performance.

Pulling 540 watts at the wall presently.

Yes I think I am aware of what you are attempting.

As far as the cores are coming online. I know that just restarting cgminer will get it running at 100% and will pull 580 watts at the wall.

I just want to see if the firmware can adjust to changes in the environmental temperature with out needing any restarts.

You can tell that the core's are indeed coming back online ambient room temp is now below 18 degrees Celsius and power draw at the wall is 536 watts @ 120v.

​Note: You can see from the details that providing a low ambient temperature enables the vrm's to start using more power even if the cores were never originally disabled. You can see that occurring with ASIC Board 0 from the results with 25 degrees celsius ambient room temp to sub 18 degrees celsius ambient room temp.

Seems ASIC Module 4 VRM #4 has an issue with temperature.

I have made a note and will later on see if putting a heat sink will help mitigate that.

Power at the wall is 536 watts. I will leave it for a few hours and see if it climbs in GH/s and if the power draw at the wall goes back to 580 watts.

Here is the core temps and details at room ambient temperature under 17 degrees celsius with case off and house fan on.

38 hours firmware v0.9.4 wattage still 535 watts.
Note that when operating with v0.9.4 at full potential the power draw at the wall is 580 watts.

I have lowered the ambient room temperature back down to under 17 degrees celsius/62 degrees fahrenheit.

It seems that firmware v0.9.4 does not turn back on what it may have turned off. I will wait a few more hours at this ambient temperature to see if the GH/s and wattage goes back up automatically without restarting cgminer.

Would be nice if the KnCminer software dev's would just tell me if that was in the code Oh well.

Here is the core temps and details at room ambient temperature of 25 degrees celsius with case off and fan on.

Kano is of of the persons that volunteers on the cgminer project.

You do not need him to setup this. However you do need to modify the miner.php file that comes with cgminer and host it on a server. Then in the cgminer.conf file you will have to adjust the jupiters settings under the api line.

..................

Yes and you can read about setting it up on the cgminer documentation under miner.php

I had to make the tests that would tell me what the culprit to the performance hit is.

Very well.

I may as well do that first before attempting to see what the max performance from this unit would be using firmware v0.9.0 and adequate air movement along with a low temp environment.

Okay just completed my final run of tests in order to put one of my suspicions to rest.

It seems that firmware v0.9.4 is highly temperature sensitive. For the last 3hrs I raised the ambient room temperature to 25 degrees celsius in the room.

What I notice is that the processor temps themselves remain low however the unit starts to slow down and the power draw at the wall also goes down.

It stabilized at 535 watts and the performance dropped down under 510 GH/s.

I will provide the screenshots of the details below. If you take the numbers from the last time I updated you and correlate it to the numbers I am going to give you. You will see the results for yourself.

Straight away you notice the hardware error % went up rather than down.

Again this is just the case off the unit with the house fan pointing down on it with the exception that I raised the ambient room temp to 25 degrees celsius.

Firmware v0.9.4 results after 36 hours no cgminer stall or restart.




36 hour results


37 hour results


In conclusion, the results help support my suspicion that the components on the board were overheating is indeed correct. Based on the results I can say with certainty the components on the boards themselves are overheating. It may very well be the VRM's.

Increasing the airflow in and out of the case will not be the only needed steps to resolve the issue. One will need to also provide additional heatsinks on the troubled components in order to maintain an operating performance above 530 GH/s.

EDIT:

I will revert the unit back to firmware 0.9.0 to see if providing adequate cooling will increase the overall performance beyond 540+ that I was getting.

Instead I will just see if changing the intake fans to a higher CFM model will help.

Yes that seems to be the simplest solution at the present.

I will be swapping out the stock fans for 175cfm ones.

I will post the the results on my first impressions post that can be followed at the link bellow.

Thanks Kano once again.

here is a ss of the results after 24hrs.

Pulling 580 watts @120v but I had to take special steps to cool the unit with better ventilation.

Before I was pulling 500 at 540 watts.

I plan on improving the case airflow by simply swapping out the two intake fans with higher cfm fans.

You can follow the results at the link below.

KnCminer results after 21hrs on open case and fan pushing air downward onto components.

I am close to 24 hr mark myself.

So far the performance is the same once I supplied acquitted ventilation.

Here is the 13 hr update.




Note: The next test will be swapping out the two stock fans that ventilate the unit and putting the case back on to see if just doing that is adequate.

5 hours into mining with open case and fan on firmware v0.9.4

I forgot to include the 50btc.com results

Here it is. Hardware errors are down to 7.4% and power is at 580 watts at 120v

Thank you for providing your experience. It helps with getting others to tweak their systems for their environment.

Here are the results after 2 hours on v0.9.4.

Okay Update.

This is the results after 1hr on firmware v0.9.4 with the case cover off and the large fan placed on top pushing air down.

Yes I needed to restart the miner because of the api configuration settings. (Thanks Kano for the help!)

Results after 1hr on firmware v0.9.4 with adequate cooling.





Note: You can see from the results that this performance is far better then the results we have seen with the case cover on and relying on the stock fans to move cool air into the unit and the hot air out.

Wanted to add that the power at the plug is at 570 watts.
