GTX 780 Owners Club

Very nice system Alex

Good work.

MOOGLEYS · 27 May 2013 at 19:09

Can't say I had any issues with my 670's no stuttering or anything. The 780 feels like a 670 on steroids but for me it does not match the grunt of 670 Sli but for a single card does surprisingly well matching Titan most of the time.

Very happy with mine.

Thanks guys. Boldey it OCs I imagine very similarly to the stock cooler. On the stock cooler though I suspect it throttles down when at 70-80+ C. The liquid block allows me to OC with no worry about temps or fan noise.

What this card really needs is an unlocked bios to enable more voltage control and a power target higher than 106%. My card never reaches more than 96% power even OCed.

Haven't finished testing but so far I've got up to +215 core and +200 mem. There's a bit more to be had on this stock bios.

Has anyone had the guts to try a Titan bios ? I know Nvidia say they are lasered off but who trusts Nvidia....

I would not recommend it, don't forget the 6gbs of vram on a Titan. I don't know a lot about graphics card bios but you could end up with a bricked GTX 780.

Top notch

No way I'm trying just wondering if anyone had. There are a few rumors floating around the net that it has been done and shows as a Titan on GPU-z ?

Well of course it will, as the BIOS is how GPU-Z reads a card.

If you flashed a 7850 with a 7970 BIOS (outside of the fact that it wouldn't actually take) GPU-Z would read it as a 7970.

I doubt your cpu is causing much of a bottleneck if any. A guy on here is running the same cpu with dual titans. His does bottleneck those cards a bit but that's 2. Bf3 likes hyper-threading so make sure you have that enabled.

how do you know if you have hyper-threading enabled? Sorry for the random question guys

Use CPU-Z

In the lower right hand corner are two boxes for Cores and Threads. If you are using a quad core CPU with hyperthreading those two boxes will say 4 cores, 8 threads.

spoffle · 27 May 2013 at 19:53

Don't even need to use CPU-Z, you can use task manager to show how many threads your PC has available to it.

It'll say cores, and then logical cores.

Loxa · 27 May 2013 at 19:56

Ok cheers guys, was just reading google and some people said it was better to have it off for gaming but that makes no sense to me LS

Who really knows what the bioses can and cannot do, they have been encoded and locked down for a good while now, it takes smart boys ages just to find a clock or power entry string.
who's to even say the latest chips don't even have an element of self test built in. But Nvidia saying they have been lasered, leaves little doubt they have been regraded somehow, best stick to the conventional methods to increase performance, I would think

I've been OCing my card wrong LOL!

In EVGA Precision I left the power target offset at 100% which means the gpu clock was not ramping up with the core offset at 147...

Time to re-run benches

Edit*
OC Scanner test passes after 5 minutes of letting it run.

Does it? I might be blind but I can't see anywhere.

With that ek back plate can you fit it after the waterblock.
Or is it like the xspc ones that you screw into each other?

With those settings what does your clock speed boost to during heaven benchmark? Check gpuz sensor tab afterwards and view max values. Also try with temp target kept at 80, I think that lets the boost value go higher.

Yes you have !... Get some cool air to that Card.

Yes you can. It is optional. If you do install it, there is additional passive cooling from the back. All you do is take off 4 screws from the waterblock installation which are used to mount the backplate (with another 2 screws on the side).

I need a knowledge bomb after reading mrk's post.

I'm running +150 offsets so 1012 GPU, 1123.5 boosted and 1652 Mem, 6608 effective.

I have not touched my power or temp target and my 780 seems fine running Heaven 4.0. Just to see what would happen I upped the power and temp target to 106% and 94c and ran Heaven again and nothing changed.

Am I missing something? is it his 300 mem offset requiring him to do this? is it silicon lottery not requiring me to do this?

Answers greatly appreciated, I am new to this software.
