Things I know:
Voltage: Increasing voltage, just like with the processor, can increase stability at higher clock speeds. The ratio in which voltage increases stability at higher clock speeds gradually declines until it takes a much higher voltage to add a little more clock speed.
Power Limit: Increasing the power limit allows the card to use more power. This essentially allows the card to overclock further, and gives it more headroom at lower temperatures.
Temperature Limit: As the card comes closer to this limit, the clock speed gradually drops to prevent overheating. An overclock at 60C that is stable may not be stable at 30C as a result of this.
Clock Speed: Core speed typically makes a larger difference than memory speed, but causes instability more quickly. Most people overclock this first until the card crashes, then adjusts memory speed afterwards.
Memory Speed: Memory speed makes less of a difference in overall performance than core speed. However, once core speed is maxed out at the desired voltage, you can add extra performance by increasing this value.
Fan Speed: Can be adjusted to preference between noise and performance. Increasing this value with a stable overclock could make it unstable due to the power draw of the fans, thus it is better to leave this at 100 when finding a stable overclock.
Okay now that I have said what I know, where is what I don't understand.
When monitoring the card in MSI Afterburner, I have noticed that the power limit and the voltage limit are almost always at 1.
Question: Does this mean the card needs more voltage and/or power in order to perform faster? Thank you.
