Hi,
I wanted to share my results and to hear your opinion:
I only overclocking GPU, memory is stock frequency

i7 2600K@4.8GHz 1.46v
GeForce GTX780TI reference rev 1.0
Drivers: 331.82
Bios stock without any modification
Windows 8.1 Pro x64
ASIC quality: 77,9%

biggrin.gif
GPU: 1299MHz 1.162v ; Mem: 7000MHz
biggrin.gif


Benching everything: 3dmark 13, Vantage, 3dmark 06, 3dmark 11, Tomb Raider, Valley benchmark, Heaven 4.0 with tesselation on Extreme, Nvidia New Dawn, games: Battlefield 4, Crysis, Crysis 3, Metro Last Light......


Valley benchmark runing a couple of hours on the extreme mode:D
But in one game I have error: aplication error and close the game (no drivers error) - NFS RIVALS after 30 minutes:mad:

Maybe my PSU causes this error???
My PSU: Chieftec 750W 4x18A on 12V+

Okay, I have sold off my 780 Ti...
Wasn't too happy about having a chip that could do 1189MHz max when that clock is stable all the way down to 1.062mV which is crazy good but hitting a wall on core clock on a golden voltage/core chip is stupid.

So I'm just waiting for the 780 Ti Classified which should be released in 2 weeks. thumb.gif

Dont think so, you have tested with much demanding software and didnt shutdown, 780Ti with 1,162v is hardly pushing too much amperage out of those 18A 12v lines so, no its not your PSU, its probably a bug in the game! thumb.gif

Ok, but I read that GTX780TI needs 43A (1x6 pin & 1x8 pin) so my PSU give 18A + 18A = 36A rolleyes.gif

OR.. MORE!!!! over 1,40v you are seeing a power draw over 500W!

A quote from one of my posts:

"Bear in mind that my system is in my SIG and the only difference was the CPU@4.8Ghz@1,30v! Using triple monitor 3240 x 1920@120hz SLI TITANS W/ Skyn3t Rev2 bios
and memory at stock 6000mhz!

1306mhz / 1,37v / power draw 124% / load 99% 372W*
1333mhz / 1.37v / power draw 134% / load 99% 402W*
1359mhz / 1.37v / power draw 139% / load 99% 417W*
1385mhz / 1.37v / power draw 145% / load 99% 435W*
1400mhz / 1.39v / power draw 155% / load 99% 465W*
* one card only

As you can see voltage alone will not increase power draw until you increase clocks and dynamically load your card, power was being drawn from the wall ranging from 850W - 1250W!

This is why you see multirail PSUยดs shut down when OC your GK110! thumb.gif

Cheers

Ed

EDIT: Just a small exercise i made in another post:

6 Phase VRMยดs (CORE) 60A each = 360A

DC-DC = I(A) ร— V(V) = P(W) =ยป 360A x 1.6v = 576W Theoretical MAX Wattage for the core

Plus 2 Phases for the memory and the rest of the card!

@ 1.40v = 504W
@ 1.45v = 522W thumb.gif

Who cares ... here's OCN ... just give us 1.4v rather than those miserable 1.2v ...tongue.gif
