No you can't, but read on. When we learned that NVIDIA's upcoming GeForce GTX 770 uses a GPU not unlike the GeForce GTX 680 in specifications, we overlooked one possibility, that it uses the same exact chip, the GK104. We assumed that NVIDIA could release a new ASIC codenamed "GK114" or "GK204," which features higher energy-efficiency, and GPU Boost 2.0.

No doubt the core and boost clocks are doable for most GTX 680's, but that 7000Mhz effective memory is going to find more than a few 680's wanting.
Thought so. When we learned that NVIDIA's upcoming GeForce GTX 770 uses a GPU not unlike the GeForce GTX 680 in specifications, we overlooked one possibility, that it uses the same exact chip, the GK104.

The GK104-425 variant rumour had been floating around for a while

what? nearly all gtx680s do those clocks right out of the box already.

So, besides higher memory clocks the 770 doesn't offer a single ounce of performance improvement over the 680? Like said before, even the core clocks are easily attainable on the 680! :shadedshu

On the plus side, this means I already have 4 "770s"... WTF is wrong with Nvidia? Are we sure that GPU-Z shot is correct?

I've no doubt that any of the better binned (factory OC'ed) cards should get there. I was thinking more of the vanilla 2GB boards (reference design/reference clocks) in circulation. I seem to remember that the scope of memory overclocking ranged from ~6600 - 7000+, and not every reference 680 made 7K.
So, besides higher memory clocks the 770 doesn't offer a single ounce of performance improvement over the 680? Like said before, even the core clocks are easily attainable on the 680! :shadedshu
If Nvidia retain the same reference blower and shroud followed by a quick onslaught of vendor designs, then its 7970 GHz Edition/ 7950 Boost redux.

I wonder if a BIOS flash workaround works for the GTX 780M as well ?

Yes, that memory clock is not easily attainable on the 680, Nvidia must be using parts that are rated for much higher clocks for the 770

I doubt Nvidia would let some thing like this happen. Even if its the same card.
For all we know they could have looked into the coding of GPU-Z and checked what W1zz has the 770 guesstimate specs and then changed the bios to show up like this...

If i have a reference cooler on my zotac 680 this http://www.zotacusa.com/geforce-gtx-680-zt-60101-10p.html

I wonder if the standard cooler can handle that ram speed and core clock :S i im not brave enough to try this out, but seems really awesome that we can flash it ;D
Just use normal OC software to use these speeds. It's really no different

does it mean GTX 770 can do SLI with GTX 680?
It most probably won't. SLI is locked to same device ID (unless NVIDIA changes their mind). And the BIOS does not and can not change the device ID.

cool! then i just set the same clock speed as the 770 with no bios update, but im current at work. but will afterburner allow me to set the ram speed that high? and can i leave the voltage at standard as it is now?

Yes you could do that, but even if it's stable at that clocks it won't turn your card into a GTX 770.

yeah i know, but im not the best overclocker, so if i just use the clocks the 770 has, then i get a little boost, i just wonder if my standard cooler can handle it ;D but i will try this out when i get home.

Whilst this bios is exactly what bta says it is this is still the Exact type of thing nvidia loves to and often does ie new bios on old chip = new card = more cash.

my 680 already does 1267/7000 on a custom bios, so the only upgrade for me would be a 780 or titan, right?

Titan brought a new Boost algorithm, so it's only reasonable to expect that GeForce 700 uses the same algorithm, or an even more advanced one.

But you are right of course, it's a business model that exists everywhere and will continue while people buy new products.

So in fact the GTX770 will be a "GTX680 GHZ edition", like AMD did with their cards?

Technically the GTX 680 is already a Gigahertz edition (1006 MHz base frequency), although I'm hoping that Nvidia raise the base clock to 1111 for the 770...just b'cos

Yeah I'm just talking about the principle of releasing a card which simply has higher clocks than the previous model and a few more software tricks. If they actually sell it at the same price as current GTX680 and lower the price of the 600series it could work well for nVidia.

Just as much as this means that Nvidia will be buying out AMD. Get your 8970 with CUDA cores!!!

hahah ye ok.

That just reminds me of a friend few days ago who showed me GPU-z pic from Ocaholic where we could see a GTX780 with 6GB RAM and DX12 support. And was like: don't these guys on this site check what they are uploading? (they were really convinced it was a valid rumor even with that DX12 lol)
