Now I hope EVGA can let me know why on Earth is the GTX 960 SC hardware limited to 100% of power limit only, when the BIOS clearly shows that there is an allowance for a further 10%. What is that supposed to mean? If there is a hard limit at 100%, why then even allow the "illusion" that we can set the power target to 110%? I even confirmed with GPU Shark, again it shows my power never exceeding 100% even when I set the limit to 110%, and it keeps showing "Power Limit Reached" under the limiting policies. Then the second screenshot he shows me a GTX 960 SC (same as mine) and sets power target to 100%, and the power reading during the benchmark shows 97.4% and he says "EVGA PX functions properly" and calls it a hardware limitation. First screenshot, he sets a GTX 980 Classified to 110% power target and shows a power reading during a benchmark at 111.4%. He showed me two screenshots saying that "things are working". So I am 100% certain it hits the power limit in the case I mentioned above, and I am saying this, when I set it to 110% I don't believe it gets "applied" to the GPU, for whatever reason. The GPU now uses up 98% power on the graphs. Now, the moment I reduce the power target to just 98%, I can see the clock speeds decreasing. The GPU doesn't use the 110%, and there is zero performance increase after increasing to 110%. The thing is, I have compared the graphs before/after (via MSI AB and Nvidia Inspector) and they're hitting the power limit at the same points. I'd say overclocking 123MHz on the core (boosting till 1541MHz) and overclocking +400MHz on the memory would be considered a "hard" overclock for the 960 SC. Generally unless you're pushing a hard overclock, you're not going to see the card draw extra power from increasing the power target, and even then it may not if the drivers and card determine it's not necessary. But why is increasing the power limit via either of MSI AB or EVGA PX not working? Can someone please hazard a guess? So long story short, is there a "hidden" setting that needs to be enabled/disabled to actually allow the GPU to draw that extra 10% of power?ĮVGATech_JaesonW Like Saijin said, increasing the power target allows the card the possibility of drawing more power, not that it necessarily will. So the allowance is there in the cards BIOS. And it shows, my 100% power target as 128 watts (matches EVGA's rating) and 110% as the max at 141 watts. I then downloaded the BIOS of my GPU and checked it using Maxwell Bios Tweaker II. Instantly I see lower power usage %, lower clocks and lower temps. Clocks do not increase, power usage % remains the same, temps do not see an increase etc. There is no difference at all when I compare the power consumption graph before/after increasing from 100% to 110%. No, when it is hitting Perfcap it uses 100%.
