NVIDIA BIOS Editor?

Hmm but the card cant keep pulling power indefinitely. Vrms would probably get overloaded.

As said above using Furmark is pointless and can damage your GPU.

Its the best gpu tester around.

It's really not.

Fixed that for you.

I find it odd that the 6pin plug is rated at 75w yet the 8pin plug is rated at 150. Looked to me that 2 extra ground wires doubled the power capacity? Seems odd.

Also there are 2 temp targets in the bios. One temp target is set at 79.53c and the other is called max temp target and set at 95c. Whats the 95c one for?

The pcie power thing is because with 3 12v wires you are nowhere near the physical limt of the wire at 75W, not even at 150W. The two grounds act as sensor pins that tell the GPU it can safely pull 150W through those pins. Your whole computer is powered by a 3 pin connector.

I imagine the first temp is limit is the boost limit, normally around 80C for nvidia cards. The 2nd is probably the failsafe limit before aggressive thermal throttling.

thats true however, thats 240v and 13amp rating on that side of things.
for the gpu we are dealing with low voltage and high current, which requires thicker wiring.

yes the temp target is set at 80c and the bios shows a max temp target of 95c. so i guess at 95c it will do major throttle or shut down?

has anyone done any undervolting on kepler to lower temps?

That's why you use a custom bios that raises the power limit. You can draw a lot more power through the PCIe connectors than they are "rated" for.

But doesnt always mean the card can handle the power though....................
