ASUS DirectCU 2 GTX 780 ti OC edition overclocking.

hey guys. so i have an asus gtx 780 ti and im trying to find the optimal settings for it. so the problem i have is this:
I dont know what to do with voltages. i can put the core clocks up fine and memory fine. but it will always stay at the same voltages. right now i have the core clock at 1200Mhz when its boosted and memory at 7300Mhz. Now that card does run fine on these overclocks. but what i have seen is that sometimes it will come up with a directx error and close down my games. Is this just from the clocks being too high? or are the voltages too unstable and low for this kind of overclock? The voltage will always stay at 1187mz under load no matter what the clocks are.

Bare in mind that it will run 3DMark fine.. there are no artifacts or blue screening. it just comes up with that error with direct x and closes the program. This card is only 2 months old so its not breaking.

Im only asking so i can find out what my optimal settings are with this card. So i can play with it at maximum for short periods of time. Plase help me out. thanks. :) 

My system specs are as follows:

CPU: i7-4770
Power supply: cheftech 80+ bronze 800W PSU
RAM: 16gb 1600Mhz
Motherboard: asus Z97-A
GPU: info.

So its a direct X error? Its not saying something like nvidia video drivers have crashed and recovered? Do you not get the direct x error when you run at lower clocks?

If it is your nvidia drivers crashing it is probably due to too high clock rates...

No.. i never got it before.. i only got it when i put the core clocks up to 1150 (1202 boost). i think its strange. Thats why i came here :/ 

if the clocks are too high. could i raise the voltage at all to maybe stabilize it?

Yes increasing voltage will make it more likely to be stable.

ok thanks, do you know roughly how much voltage i should go up by? and will it decrease the life of my card by much?

I'm pretty sure its limited so you can't move the volts "too high", its been awhile sense i OC'd mine but i think i just moved the slider all the way up... I use MSI afterburner. I think it just a power target slide. I'd have to be at home to make sure, at work right now.

does all this make my graphics card warranty void? i mean.. the program to overclock came with my card. and it does have limits. so my warranty should be fine right?

and thanks a lot for your help :)

Your warranty won't be void for OC'ing.
