Those are default values for the controller implementation, my guess nvidia didnt mess with them

Not really. Do note that nvidia is already adding an extra offset of 18mv with DD=03. Why not set that to 00 and set LLC to 0, same voltage applies there will be no lifespan shortening.

download GPU-Z and right click on the top of the window, > asic

Makes sense to me now did nto think of relating it to a chip, on Air I would assume we wouldn't need to account for LLC really.

You can use gpu-z to read your asic. Not necessarily high asic correspond to high OC...

that doesnt answer my question. a card with normal LLC and BIOS Voltage set at 1.212v will result in a loaded voltage of 1.18v. a card with LLC set to maximum and bios voltage set to 1.18v will result in a loaded voltage of 1.18v. So my point is that the loaded voltage is the same either way. So why do nvidia not just release cards with a slightly lower bios voltage and LLC set to maximum? it would produce the exact same result.

So I am looking for someone to explain since all 3 methods can produce the same loaded volume, which way is better and since the loaded voltage is the same in all 3 what is the difference?

Ok flashed with Occams AMAZING Help...

Now to Overclock them but here you guys go:
http://www.techpowerup.com/gpuz/4zx9z/
http://www.techpowerup.com/gpuz/3yf2r/

Looking for Asic

GPU1 (not sure which port) shows an Asic Quality of 74.1%
GPU2 (not sure which port) shows an Asic Quality of 61%

I take it 61 is bad?

So why does nvidia not do this? why do they prefer a higher bios voltage and lower LLC regulation?

I understand the LLC function is when changing clock and voltage there is a short moment when more voltage is needed than the one needed once it is stable. For example card idle at 300mhz with ex 0,8v then the card is put under load, 1150mhz and 1,212v soon after the LLC tells how much the v can drop and the volts go down to example 1,18. If it would jump directly to 1150/1,18 there would be more risk to crash. If it would stay at 1,212 it would use more current for nothing.
Tell me if I'm wrong.

By the way I just readed ten pages of this thread wink.gif always following.

On my pc I reinstalled windows 7, by the updates in the first 3 days it got unstable, means it sometime fails at boot frown.gif
I'm also having some strange slow downs almost like Luna frown.gif (haven't disabled the services running in background yet).

Question what drivers do you run? I installed the 314 as, if I remember correctly, crysis2 worked at best with these.

If you like fps games and fast action I invite you to come to play crysis2 multiplayer, the 10$ for crysis2 maximum edition are the money I best spent in my life (well no maybe at first place I'd put a condom) wink.gif

Cheers guys smile.gif

By the Way Does anyone know how to permanently turn off Geforce experience on Startup? It seems it always crops back up... soo annoying

Do you know of what is ASIC the measure?
Is it an esteem due to values ex. Volt/clock? Have no idea

When in doubt, follow the money with applied business logic...lol
My guess is this allows Nvidia's AIB partners to price differentiate otherwise identical skus based on a nuanced pwm controller that can adjust LLC , thus effectively resulting in different boost values out of the box. So for example, SC vs non SC evga version of the same card, and so on.
Just a guess though.
