Gigabyte GeForce GTX 780Ti WindForce 3x OC Driver/Card problem

hello all,
i recently bought the Gigabyte GeForce GTX 780Ti WindForce 3x OC (http://www.overclockers.co.uk/showproduct.php?prodid=GX-129-GI&groupid=701&catid=1914&subcat=1402) the card runs great on some games and AWFUL on others. it seems i can play ultra BF4 without any issues however when it comes to playing diablo 3 or some other games on any settings i get black screens that do weird graphics effects for about 5-10 seconds and sometimes crashing my pc on a frequent basis.

when it lets me tab out i get the microsoft message "Display driver stopped responding and has recovered, Display driver NVIDIA Windows Kernel mode driver, version 335.23 stopped responding and has successfully recovered." at the bottom of my screen.

I am wondering if anyone else knows of this issue or has had it, is it a faulty card or a driver problem. Things i have tried:

driver sweeper
clean driver reinstall
updating to the latest nvidia beta driver (seemed to help a little and fix for some games)

thanks for any insight you can provide :)
 
You need to find out the exact model its most likely your PSU is not strong enough for this card as its very power hungry especially with its factory ocing.

Without taking anything part look inside your case you should see a label/sticker somewhere on the PSU.

If your ocing your CPU/Ram run that at stock speeds as any ocing especially with a weak PSU will create issues not all PSU's can supply enough amps on the rails you really need a powerful PSU if your heavily ocing your system with this GPU.

Some games will be fine some will not as they all place different demands on the GPU & do not use the exact % amount of power which is why some games work some are unstable.
 
Well i have gone through my order history (as i bought my PSU from OCUK) and the exact one I am using is OCZ ZS Series 750W '80 Plus Bronze' Power Supply (no longer being sold by OCUK).

would you say that is enough to run my system and this card, im using an intel i3 overclocked to 4.2ghz, 16bh ram and a 250gb ssd.

the thing is i have also noticed reduce performance then is shown from benchmarks people have taken with the same card (my average in watchdogs is 30 and the average in others is 60) is this also caused by not enough power?


thanks for any help

It's the card I'm afraid, a lot of Gigabyte 780s seem to be unstable, try downclocking by 20Mhz or so.

Then why pay the extra for if its not stable, also i dont see how this would fix my performance in some games (watchdogs that should average 60 and i am averaging 30) by downclocking?
 
He is not asking you to accept it for keeps but to try as a temp test.

Lower Core/Vram clocks and see if its stable.

Also that PSU will not be that great, what are AMPS on 12v rail(s)?

Edit, single rail with 54 AMPS for CPU+GPU and all other 12v devices.

GPU need : GeForce GTX 780ti - 42A and yours is an OC model.

jh30uk, thanks for the really helpful reply however im not yet so tech savvy meaning im unsure of what it all means. it my PSU not enough or is it taking to much and leaving not enough for the rest of my system?
 
Both, its not a good PSU for a PC today and it cannot power your CPU+GPU and all rest of 12v devices with that Amperage on a single 12v rail.

You need a new PSU and the GPU may be fine.

are you seriously pulling numbers from air?
the power draw at the wall for a overclocked 780ti system is 450w. that is equivalent to 420ish watts being supplied by the psu to the components.
his psu can supply 650w ergo is sufficient
 
Read the links I provided FFS. :rolleyes:

Do you know understand AMPS needed?

The exact same issue in 2 other threads lately, WATTAGE was above min spec but single rail was weak in AMPS.

This is really helpful indeed and i suppose its time for a psu upgrade, if you wouldn't mind going the extra mile would you help me find a suitable one so i don't make the same mistake again? I was looking at this one a few days ago: http://www.overclockers.co.uk/showproduct.php?prodid=CA-004-EA&groupid=701&catid=123&subcat=2464
 
your link doesnt tell me anything.
it is well known that manufacturers overstate the power requirements to allow for poor quality psus.
ocz may not be an A grade psu company, but they're far from the worst either.
