So I've been playing around with overclocking my new ASUS STRIX Edition GTX 970, and while doing so and watching the 'Power Limit' graph in MSI Afterburner, I notice that the card hits the power limit constantly regardless of clock speed, core voltage, or power limit adjustment. Even at stock speed when running Furmark or the current version of 3DMark's tests (like Fire Strike or Sky Diver), I'll see that graph bounce up and down like crazy. Now mind you, this particular 'graph' only has a value of '0' or '1' which I take it to mean the card ISN'T or IS hitting it's power limit.
You'll notice the 'Power Limit' graph in Afterburner in the screenshot above... bouncy bouncy and this is at stock clocks and voltage. The graph jives with that Furmark says too, Furmark has a 'limit' portion of the OSD and it's on '1' most of the time.
I would think at stock settings the card shouldn't be constantly hitting it's power limit like that - but then again I have to admit not FULLY understanding how Nvidia's GPU Boost and thermal / power algorithms all work.
Or maybe MSI Afterburner is just reading things wrong?
