GTX 780 Owners Club

HEAT is electronics Arch enemy, control that and a little more voltage would not be damaging, but every extra 10 degrees Centigrade hotter you run Life is halved

Ah fair enough, I was considering bumping the speed of my card up to the clocks of whatever is the quickest one out, leaving the voltage at stock and just using it like that

Google 'GTX 780 ti bios'

It gives 1.212v and disables boost. I'm using it, very good bios.

Any chance you could "Trust" me the site as I got like 50 different results.

So the GTX 670's are out and the GTX 780 are in !

Don't even comment "the cable manangement" - I've answered that 1mio times. I know there are new better cases but I like my 6 year old case - EOD. It's no beauty inside and won't win any contests, but I like the outside looks.

How much of a difference does the OC on the cpu make to the Unigine Valley and Heaven scores?

As good as 0% since those tests only stress the GPU's (well 98% GPU stressing only).

You could do with winding the CPU up a bit as it will hold your GPUs back a bit.

This is a very extreme example but it depends on how fast the cards are.

In both pics below the cards are running at stock clock speeds, the only thing that changes is the CPU speed.

Yeah, I am seeing differences between my scores and ones running with OC'd cpus. My score seems to be 400-900 less. Obviously my cards clock speeds arent identical but there pretty similar, so I am guessing its that or drivers holding me back.

Drivers do make a difference but providing they work it is not a huge difference.

I got a huge difference between CPUs.

~1900 scored at 1080p maxed settings with a 1100t @ 3.5ghz (58fps average, min 11, max 68)
~3000 scored at the same settings with a stock 4770k (72fps average, min 27, max 140)
the GPU was overclocked +200 on core and +600 on memory both times.

i wonder what marks i'll get when i overclock the CPU and push the GPU a bit further under water!

Wow that's quite a difference ! I never experienced that. Back when I had 3x GTX 580 and core i7 870*and just upgraded to a core i7 3820 there was only a 1-2 fps increase.
Could it be in such extreme scenarios with 4 gpus that they are actually waiting for the cpu to process the information ?

Yes but it also happens to a lesser extent with fewer cards. If I was to overclock the cards without doing the same on the CPU it would not a pretty sight, things become very jerky indeed where the cards have to wait for the CPU.

The valley bench is a no go area @1080p for any more than 2 Titans as the fps are very high causing a bottleneck. If it is run @1600p with an overclocked CPU things are fine and there is no bottleneck.

It's a funny one really, If you game on a single monitor at 1080/1200P, games seem to fall into 2 categories, the ones you can play with power to spare and then games like Crysis 3 that even with a super OC you will not get the fps you want.. So is all the extra heat and noise and running on the edge worth a couple fps ?

Each to their own but for me, unless your going to water cool it and properly OC it's not really worth it except for a bit of fun with benchmarks

Nvidia has pretty much squeezed these cards as much as possible already.

Hey guys,

Got my Gigabyte 780 a week or so ago and loving it so far, running at 2560x1440 and it is coping very well.

Managed to get a clock of +150 core / +100 mem so far. Have been able to push the core to +190 in Fire Strike but it is not stable in gaming, I kept getting a CTD in Crysis 2 when running ultra. I also adjusted the fan speeds and is hovering just below 70 in gaming.

boomstick do you know any webpage how to flash it?
I feel like i want to try it today
have you tried hydro copper bios? just wonder if there is any difference between ti and hydro copper?

 

[Boomstick777]

After a couple weeks with this 780, my honest opinion it is the best GPU I have used, build quality of the card, performance in game, power use, really exceptional. I even prefer it to the Titan because of it's cost VS performance.

Performance really is amazing, not had any problems in any game, smooth as silk. If AMD can bring a faster card than this in the 9XXX series along with the driver fixes I will be very impressed. It will take one hell of a card from AMD to tempt me back to the red team...

Here's the bios, I've uploaded here for you - hxxp://www.sendspace.com/file/fhu5fh

Change 'xx' to 'tt'.

Take care with flashing, if you can do it DOS mode, safer than Windows imho. This is the bios to use, unlocks 1.212v and disables boost while keeping low power states. Very stable overclocking.

Remember to keep a copy of your original bios in several places so you don't lose it.

What sort of overclocks are people getting on the stock voltage?
Received my Gigabyte card yesterday and managed +148 on the core before the drivers crashed running heaven and +250 on the memory (didn't push that).

You should be able to get to around +450 on memory running Heaven 4. If you have good memory chips you can go faster.

Keep an eye on the scores though, higher memory (due to error correction) does not always equal better.

Memory I managed to get to +390 before the driver crashed. But, I'm still using a power target of 100%.
Currently running these on a pre-overclocked card, so they are added onto the stock overclock.

Which gives me a total of
Core - 1241Mhz
Memory - 6580Mhz

You can try again with the power target set to 106% but just do the memory on it's own to find out the highest it will overclock to. +390 maybe as far as it will go, with this sort of thing it is all down to the silicon lottery.
