No, but largely because there isn't much of a reason to.

With a GTX 680, you sure can. It is basically the same as a GTX 770.

Nope, sure didn't.

I have a DCII TOP and I'm already here without overclocking:
GPU Boost Clock : 1201 MHz
GPU Base Clock : 1137 MHz

all I need to do is see if I can clock my memory near the 7GHz mark and it does have a DIGI+ VRM with 10-phases
so I'm not sure if that BIOS is a boost for me or not.
I might be better off clocking mine straight up or use the modded BIOS I have for the DCII TOP..

I'll show why this modified BIOS works in the OP. All GTX 680 RAM will clock to stock GTX 770 RAM specs.

All you need to do is save a copy of your original BIOS using GPU-Z, if you'd like to flash back.

It sure does. This boosts to 1202. You can see it in the OP.

after seeing the screenshot of the GPU's I thought of a few things.

1.) very shortly after the GTX 6 launch nVidia already had Boost 2.0 and GTX 7 series working and in the plans.
2.) also think that more cards will be able to flash mod to GTX 770 and several models will have the exact same layouts, not just a few.
3.) Boost 2.0 can run now on GTX 6 series cards

but I'm also drinking a few Heinekens..

That's correct. GTX 680s have this feature built in to it's BIOS.

KGB BIOS unlocks voltage, but doesn't properly set up the stepping per clock rate. It's almost like a quick hack, in my opinion.



Moved pics to the OP. wink.gif

Hmm this is interesting, however my GTX 680 is barely stable at 1750 on memory as it will sometimes artifact with EVGA OC scanner X.

I've tried overclocking my stock cards and got to 1125/1700 stable on the stock voltage stepping. Once I modified my BIOS this way, I've been completely stable with all testing. I've ran Heaven for 6+ hours while I slept, OC Scanner with GPU memory burner::3072MB for an hour+, and have been gaming without any problems whatsoever. I am also water cooled, so I haven't seen what temps this would reach on air. I max out at 47.



Anyway, I'm leaving this here for all that are interested. You are able to extract your own BIOS and mod it as you see fit as well. I left mine attached as an example and it works for my stock GTX 680s. I enjoy having my new GTX 770s without spending a single dime. Your results may vary. Good luck. thumb.gif

for some strange reason I think I'm better off modding my own DC II TOP BIOS or just going +600 on the mem..

I suppose I will wait and see if the 760 matches a 670 and then maybe flash...

The 760 Ti might match the 670, but the 760 (non-Ti) is probably going to mirror the 660 Ti.
