Hi Patrike, I have not written to you for a long time, you are doing a great job as always, I remind you of an old request from me and I propose a new one.
Old request:
Know in statistics the times you make profit change in 24 hours and for each moment. To determine if that percentage of mining of a coin has done it in 1 change or in 30. It would help me to make better decisions
The other request is an improvement on something existing. I mean temperature control, which is going very well but I explain.
I use both methods, both the general by TDP with its two options and also the core reduction. My scheme is as follows
TDP 1 limitation: 72 degrees, you under the TDP
TDP 2 limitation: 74 degrees, even more under the TDP
Temperature limitation in each OC or core, I have it at 76 degrees
What is the problem ?, Well, it works well, but is constantly jumping temperature. I have a card that according to the Algorithm gets very hot and is always dancing the temperature of 72 to 76 degrees. Because what happens that when it falls to 71 or 72 the limitations are removed and reheated, when it is heated, the limitations are activated and the temperature is lowered, but then the limitations are removed and again heated. I think that so much temperature change, TDP and core can be even bad.
The idea or solution I see simple. If a card activates a temperature limit for example TDP 1, this limit remains active until it changes algorithm or currency. This way we avoid getting the cards receiving a constant change of TDP and CORE all the time. It is logical that if it reaches TDP 1 and 2 and the temperature drops, if we remove the limitation it warms up again. That's why I think it's a better idea to keep the limitations until you change your currency. That way the temperature would be more stable, and I wouldn't be hitting jumps all the time between 72 and 76 as is my case, I don't want it to reach 76 every time.
I hope it is understood and that you see it well as an idea, the implementation is very easy, basically because almost everything is done, just keep limitations until currency exchange, with which the temperature will not be jumping, we are not changing TDP and CORE several times per minute to the card
Hi patrike, happy holidays. I would like you to tell me something about the suggestion I made.
I think the implementation is very easy, 90% is done. It is only to maintain the limitations if they are reached and even if the temperature drops, keep those limitations. Only if you change currency or make a change would you reset
Believe me that I have several cards constantly dancing between 72 and 76 and I do not like anything, and if under the OC it is for the entire Rig, while if a card reaches a limitation, it keeps it, instead of constantly activating and deactivating the limitations and producing a temperature dance. I have already broken one of those cards and I think it's because of the continuous dance, because it always reached the maximum, it went down to 71, it went back up, so 24 hours every day. Too much stress for the card.
Thanks for the additional comments.
Right now there is a limit of 30 seconds between the Power Limit changes. This will only prevent some of the changes - but I understand your point that it still can be too many. Maybe the change should be like this:
- The Power Limit can be decreased no more frequently than 30 seconds after last Power Limit change
- The Power Limit can be increased no more frequently than 5 minutes after last Power Limit change.
This would make the Power Limit go down as fast as today - but it will not be increased so fast again. It will stay on a lower level for some time before it even attempts to go back. So instead of possibly 120 changes per hours as you could have today, this concept would give about 11-12 changes per hour.
This concept would work fine even if you would be mining for a longer period of time - as you don't have to wait for a profit switch. It would also be working for those that doesn't do profit switching and runs the same mining software and pool all the time.
Please let me know what you think. Thanks!
