1.) How does one then pick a "correct" TDP value to set? With voltages, one can adjust them bit by bit in OC software, till finding just the right voltage for an OC. But with TDP, it seems you can't do this in OC software (other than messing around with Power Limit %age).
I just don't get why there's even a TDP variable to adjust in the first place -- isn't it basically the same as a person setting their voltages?
2.) What happens if someone just "guesses" and sets a really high TDP? Like, what would happen if someone set their TDP value at 300W? Does that mean the card would constantly be pulling 300W's of power through it?
And I'm a bit fuzzy on the purpose of the the "minimum" TDP value. What's the point of that? And in the OP's guide, it seems that he sets the minimum at the same value as the TDP. I don't understand what the minimum is even for.
(side-question: ...but at the same time, the OP doesn't set the minimum value at exactly the same as the TDP value -- he set it +2 above the set TDP, which doesn't seem to make sense...? Why not set it exactly the same? And further, why set a "minimum" value +2 above the default TDP value?)
1. I think there is no ''correct'' value, if you plan to Overclock your card with a high voltage, you must either have a high TDP, or a High % Power limit. In the end it just needs to be that the TDP+Power Limit is higher then the Wattage your card uses on your maximum overclock. Or else it could result into throttling.
2. Setting the TDP to 300W doesnt make it use 300W constant, it just means without any Power Limit set, the Max TDP will be 300W before it starts throttling.
3. I think the Minimum TDP Value is the value that is used, when the Power Limit is on -20% or -50%.
If you manually edit that Value, example 300W TDP, 300W Minimum then with the Power Limit set to 0%, the Max used is 300W.
By manually setting the minimum TDP higher, you actually lose the ability to ''Safe Power/Run cooler on old games" by setting the Power Limit a negative %.
i think setting the power limit do a negative value wont work after you set the Minimum TDP to high
I think the minum value is used when setting the Power Limit slider all the way to the ''left''.
So by making the minimum the same as the TDP value you essentialy ''SHIFT'' the working of the Power Limit slider.
But in the end this could all be wrong, this are just my own interpretations of the value's etc.
I didnt manually set the Minimum and Maximum TDP. I just set the Power limit to 50% and the TDP set to 250W.
Giving me a maximum Power Draw of 250W + 50% = 375W Power Draw.
Perhaps i need to go higher when i apply higher Core Voltage, but so far it works perfectly.
When i play some older games like Counter-Strike Source i set the power limit to -30% and see my GPU Temprature are very low.
