Heat travels upwards. ACX will be able to cool itself better against the heat produced by the reference card. I have the exact same GPU setup.

Right, so the ACX at the bottom won't intake any heat at all and the blower won't mind the heat if it is at the top since it will take in cool air from the side. How would the way it is now work better?

....let me rephrase it.

Reference card has lesser cooling potential.

ACX has higher cooling potential

Heat Travels upwards. Thus, the card on top will be exposed to more heat.

You want to put the card with higher cooling potential on top to minimize the difference in temperatures between the two.

Yes.

Same here. Max performance does nothing.

Just started playing Hawken and tho I am below 120 FPS, it still clocks me down 230 Mhz.

I wish I would never have touched this BIOS. mad.gif

I bought this 780 ti from Gigabyte http://www.amazon.com/gp/product/B00GFZPE2S/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=AZ8ZZL30AH7DI. Does anyone know what vbios i should use, the "GTX 780 Reference model" vbios or "GTX 780 Gigabyte" vbios?

Running at 1084 still causes dips below 60fps, so I'd like to have a higher frequency that is applied at all times to help with that. Overclocking does me no good if it won't apply the clocks I'm setting unless a certain load requirement is met. Plenty of games don't use much GPU power, but would benefit from a higher OC.

For example: Borderlands 2 uses 30%-40% of GPU power, but I dip below 60fps in extreme battles. The overclock does not apply because the load is not enough, so I'm not getting those extra FPS to help minimize the dips. There has to be a way to force the overclock I want to run at all times, right?

Doesn't Precision X and K-boost do exactly what you're after.. forces clocks to remain what you set regardless of load. Have you tried this?

Boost is removed with the bios flash I did. I had no idea I couldn't just set the clock and it would work fine. Every other card I've had applies the OC the way I set it up and works as such. The 780 ti, not so much. But yeah, K-Boost doesn't do anything now that boost 2.0 is removed. Well, that's not entirely true as it will lock in your voltage.

Not only that, but the reference cooler dumps most of the heat outside the case, so the impact on the cards above it will be minimised.
