Reduced temps by 5% while managing 5% better benchmark scores by simultaneously OCing and reducing power target to 85% (temp target remains at 80C)

post #1 of 2
Thread Starter 
GPU: EVGA GTX 960 SC 4GB

Stock settings: 1216/1279/1418MHz (Base/Boost/Boost 2.0) + 7010MHz (Memory)

100% Power Target + 80C Temp Limit

Firestrike graphics score: 7910

Maximum temperature: 78-79C (44% fan speed with the fan curve at 45%/80C)

Minimum observed clockspeed: 1354MHz

Overclock settings: 1348/1410/1550MHz (+132MHz) + 7192MHz (+93MHz)

85% Power Target + 80C Temp Limit

Firestrike graphics score: 8305

Maximum temperature: 74-75C (40% fan speed with the fan curve at 45%/80C)

Minimum observed clockspeed: 1405MHz


What do you guys think about this? I can of course do it without reducing the power limit, but it is pointless in-game for me cause the temperatures reach 80C and my clock speeds downclock at that temperature over time. With the power limit, the GPU is producing less heat and in-game it translates to a much slower heat buildup and I do not hit 80C, and it allows for more stable clock speeds over time.

Is it normal for people to overclock this way, where there is simultaneously an increase in performance (however small) coupled with a reduction in temperature?

EDIT: To make it clear, I went down this route (lowering the power target %) because I couldn't undervolt lest I mess with the BIOS settings, which I thought was not worth it. So by tweaking the power target, I have in a way forced my GPU to undervolt itself. As you all know, increasing clock speeds increases temperature linearly, while increasing voltage increases temperature quadratically. So I used this principle to offset the rise in temperature caused by the core and memory overclock by reducing the average observed voltages.

I don't see the point in doing it as long as its running at a "safe" voltage. seems to me like you're just limiting your performance for a very small undervolt.
