[Official] NVIDIA GTX 780 Owner's Club - Page 1880

post #18791 of 24924
So, after about 2 weeks I think I finally maxed out the OC on my two 780s....phew.

Here are my max. settings:


GPU 1 - Asus GTX 780 DCU2OC @ air
ASIC: 84.1%
BIOS: Skyn3t rev 4
Core Voltage: 1.212V
Power Limit: 100%
Core Clock: 1154MHz
Memory Clock: 1552MHz


If I go higher on the Core, it freezes/blackscreens on BF4 after about 20 minutes.
I think I could push the memory some more though.






GPU 2 - Gigabyte GTX 780 WF3 rev 01 @ air
ASIC: 65.7%
BIOS: Skyn3t rev 3a
Core Voltage: 1.212V
Power Limit: 100%
Core Clock: 1054MHz
Memory Clock: 1527MHz


If I go higher on the Core, it freezes/blackscreens on BF4 after a couple of minutes.
If I push the memory further, I hit the voltage limit after a couple of minutes playing BF4.



Kinda disappointing I have to say. frown.gif

I'd say, try another game. Far Cry 3 and Heaven. And just set back to stock clocks when playing BF4 cause it's so extremely fluctuating when it comes to stability.
post #18793 of 24924
Well, I don´t really play any other game. wink.gif



EDIT: Oh yeah, a few weeks ago, I was only using benchmarks to test stability and I was able to push the clocks much much further.

Yeah it really is, I have also Gigabyte GTX780 WF3 OC rev 1.0 and with SkyN3t 3A BIOS my card is stable @ 1125MHz/1600MHz with stock 1.15V.

ASIC 74.4%, max GPU temp 73C (fan @ AUTO).

Hehe, neither do I...

Then you have to do as I've done, find yourself in it that the game is extremely unstable during overclocks and apply stock clocks or just an insignificant oc profile.

But in Battlefield during SLi, I'd recommend the stock bios since the heat is just so unnecessary since the skyn3t-bios bumps it up too 1.212v when under load. And you really don't need that much for those clocks that you've achieved.

1.168-1.175v for the good asic, and 1.175-1.187v for the one with bad asic is what you are going to need for those clocks, I'd say.

I recently got my hands on a cheap (well.."cheap") 780 Ti which I will be testing lateron today.
Just curious to see how that one performs.

If I decide to stick with my current 780s, I´ll definately put both on water.

Just a heads up for anyone that is going to update their copy of 8.1 with update 1, will save you a lot of headache.


This also happens to me.

ASIC quality < 80% - 1.1125 V;
ASIC quality < 85% - 1.0500 V;
ASIC quality < 90% - 1.0250 V;
ASIC quality = 100% - 1.0250 V.

The higher ASIC the less voltage the chip needs to operate!

My 2 Titan "dogs" only go 1150mhz@1,212V but fly all the way to 1500mhz@1,510V!
Some chips love voltage... tongue.gif


Cheers

(Team skyn3t)

My card has asics quality of 73.9% and its voltage is 1.15V. smile.gif

I have a bad luck and my memory is elpida... In all reviews i have read GV N780OC comes with samsung or hynix, but mine is elpida!!! I can clock the memory max to 7000MHz for benching and 6900MHz for gaming.

Does anyone here know how to access the very root of the software on a graphics card?

Like the very very natural bottom where the i/o controller and stuff like that resides?

Thanks in advance.

The only variable here its the update itself, why should be the bios that breaks anything? It could be a lot of circumstances including drivers and DX files borked during/by the update itself, we all know how microsoft is, there are updates that prevent you from playing some games in DX10, you have to uninstall them to be able to play, so, lets rule everything else out before blaming a bios that has not changed as the OS did!

You and over a million people would like to know that... tongue.gif
The software must be open source, if not you have to be very good at reverse engineering to be able to go deep and break the software code!

"very root of the software on a graphics card"

By this you mean graphics drivers and overclocking software? again , same as above, only a handful guys i know can do that and most of the time, when they get to it a new version is out rendering all efforts void!
