Had about $500 to burn and well the 280X is a grate card but im not about to blow $500 on a side grade....lo and behold a pile of EVGA GTX 780 ACX SC cards at my local Tiger Direct.

got my dream card and its sooooooo nice......the ACX cooler is amazingly quiet tho maybe too quiet as I can kinda hear some coil whine when the card is loaded up. Seems to be going away the more i use it.

stock it's boosting to 1097mhz and I have gotten 1200mhz without touching the voltage. seems to be on the raged edge of throttling due to the power target only being 106% but im happy.....sure blows my 7950 out of the water for my 1440P display.


Dont mind the dust....i gave it a air clean later...it was just a test for DOA smile.gif


Nearly in a near exact situation with a different GPU. I'll be going to a TD/CompUSA tomorrow and I'll probably be picking up the same card.

GPU-Z doesn't always work. If it doesn't, you can also use NVFlash

To save your BIOS, open up a command prompt and in the command prompt go to the directory where you have NVFlash. For ease of use I always just put it in C:\Classified (since I have a 780 Classy). From the command prompt:

1st step
Nvflash --protectoff
(This will disable the bios protection in order to save or flash a bios)

2nd step
Nvflash --save call.it.what.you.want.rom
(This will save the stock bios)

Use NVFlash v5.142, it can be found here:

I'll definitely take time and read your full advanced guide that I somehow missed on the very first post, as it seems to be the best way to go about this. Love a well-structured guide.

That said, wouldn't the TDP limit be hit when doing the stress tests as well? (currently the Power Limit is at 103%, which is the maximum on AB, likely due to me having the Stock BIOS, I'd wager.)
It's just odd (for me tongue.gif) to have such a great result out of stress testing with high loads and then have it go down during real gaming scenarios with comparatively lower loads on the gpu.

Yap, that will happen with hitting the TDP limit! Our bios have increased TDP limit to MIN 330W - MAX 500W for the GTX 780! thumb.gif

Thanks guys. Gonna give it a try.

my stock bios is 80.80.31.00.82 -- which one should i use?

also included my bios if anyone can tweak it like the skyn3t ones.

I've got an EVGA 780 with BIOS 80.80.21.00.80, which is supposedly the newer BIOS associated with the B1 Stepping, but GPU-Z states that my card is the A1 stepping.

I've read elsewhere (EVGA forums mostly) that this may be a bug in GPU-Z and is causing some headaches for 780Ti and non-Ti owners, a few people saying that taking the cooler off to see the chip is the only way to really tell if it is infact an A1 or B1 chip.

Can someone, maybe the always helpful all-knowing Skynet, maybe shed some light on this for me please? smile.gif

As I understand it, if your card ships with BIOS 80.80.xxx it's a B1 stepping.
I had the exact same BIOS version that came on a card I received sealed, but I also managed to get GPU-z to see it as B1....
In a related story, I had a brand new card I sold just other day and it had a BIOS sticker on it marked:
80.80.31.00.80
I'm trying to get ahold of that BIOS version because the buyer requested the original... which I have misplaced. I sent him the version you quoted.

It's taken me until yesterday from... November to figure out B1 gets Skyn3t BIOS v4 and A1 gets BIOS v3 or 3A... I just didn't get it because if you have a B1 stepping card the A1 BIOS works OK on it. I haven't tried the reverse and I wouldn't.

So I do have a B1 card......... Weird, going to make selling it to any discerning chap who wants a B1 card a few years down the road a bit tricky maybe.

Doesn't make sense why some cards that are B1 say B1 in GPU-Z and others don't, its either a bug in the BIOS or a bug in GPU-Z, right?

Edit: WOW, talk about timing. I just updated GPU-Z to 0.7.7 and after having this card for 4 and half months GPU-Z has been updated to fix this, it now says B1. (see attached pic)

Hello again!

Experimented with the rev4 BIOS for MSI on the first post and the results are quite different, if mixed! I followed all the steps in your guide carefully and all seems to be in order.

With it, I can no longer safely OC the Memory with AB past +150 without drivers resetting/system crashing (left it at +100 for the stability test overnight).
The core's result depends on the test/game used. In most (though not all) situations I have gotten it to stay at 1293MHz stable and at around 60-62ºC (fans at 75%) and gained about 90 points on the Heaven benchmark. The only test that has a negative result is MSI Kombustor's default "stress test" that you can call from AB's K button. It goes way over on the TDP and downclocks down to 901, sometimes even lower.

Still a lot for me to learn here, and reading other's experiences surely will help!

EDIT: I also seem to have it at 1.213 in AB's slider instead of 1.212? Anything I should do there?

Flashed my bios but didnt like the constant 1.212 voltage its running at. Is that how its supposed to be?

Probably due to tighter memory timings you cant OC as much as with stock bios, with mem OC you will have meager fps gains but with core OC they will be substantially higher, on the other hand mem OC might hamper your core OC stability as it takes current away! thats why you should find your max core clock first, Valley likes mem OC more than core! with benches you might have to compromise both clocks, but in games the prevalent is core clock and only some will give you higher fps with mem OC!
