I'm a fan of Gigabyte's Windforce, had the 670 and now the 780, both run super cool.

Also depends on your case, small spaces or sli would benefit more with stock cooler.

This post has links for FLIR images of the ACX, Windforce, Twin Frozr, and reference 780 ti.

The board layout of the 780 ti and the 780 are very similar. The only difference I noticed is that the Windforce in the FLIR image has 6 phases, while the 780 rev 2.0 version has 8.

EDIT: OK, I got it to work, but is there a way to save the voltage into a profile or do I have to apply the hack every time I start Windows?


No, at this time there is no way to have over 1,300V at boot (AB profiles) for several security reasons!
And why would you have your card to boot at over 1,400V? are you using DICE/LN2? If so you need to dig deeper and prepare your card for special P0 bios and your soldering iron for a hardmod!

Thanks for the response.

No DICE/LN2. Just water.
Why is 1.35v-1.4v under water unsafe if the temps would never go over 50? Isn't that enough cooling?

You dont have VRM temps avaliable, the only temp you have is core and can only guess the rest, measuring temps on the back of the card is never an true estimate as the real source of heat is on the other side and you only measure a fraction of the heat by induction, at 1,400V the amperage (current) going through the VRM modules is very high and a heat spike is enough to burn one of the mosfets (where most heat is generated) like happened to Mr Tooshort's Titan@ 1,470V (IIRC)
Water is never going to cut it with high voltages (not the voltage as its a potential but the increase current that it allows as it rises) its more suited for extreme cold (DICE/LN2)

Valley will report the wrong clocks a lot of times. Monitor your clocks with GPU-Z, Precision X, or Afterburner while you're running Valley.

No OC anywhere on machine. 3way SLI EVGA GTX 780 SC ACX. AMD FX8350 the rest of the details are in Monster of my sig.

2 of the cards are samsung ram one is a hynix ram card.

Everything I've seen so far has pointed toward valley showing boost clock whereas AB is showing core clock..is this incorrect?

edit: well, yep, looks like I'm a noob. biggrin.gif Just noticed in Crysis 3 (AB showing variations in clock speed as I played) Well dang. time to rerun my valley and go from there. Feel like a noob with a new sports car, vroom vroom. Thanks for pointing that out. thumb.gif

double edit: Followed the LLC guide and flashed BIOS. Given my setup though I had to modify Occams instructions for finding good core clock. If I set voltage to 1212 I hit 80c quick and begin to throttle, but thats not really a suprise given the setup. Going to have to either A) get rid of this h60 (2013) in favor of the h80i or similar B) order some better fans for this h60 (high static and high airflow or maybe a mix and match static to push air in and high cfm to push it all around) C) a mixture of both.

Haven't even started in the i5 yet but I'm not going to shoot for too much past 4ghz unless cooling dramatically increases, giving me more headroom for both. (i5 is just working off turbo right now so 3800 on load, but it stays manageable at 56c)

hmmmm....rolleyes.gif

When i start my computer, ssd its quick, at the swirling windows balls my screen goes blank, monitor goes into standby mode, and comes back about 4 seconds later at the desktop. Why?

my old 7950 didnt do this and from what i remember neither did the 570 i had do it either.

Should I add another GTX 780 for 3 way sli and upgrade my watercooling, or get me 2 GTX 780ti and slap on NZXT G10s on them? doh.gif

Edit: Oh yeah im gaming @ 2560x1600 that's my reason...thumb.gif
