Updated for DRBoss, your card clocks a little better than my Lightning. Core is stable at about 1270-1275 and memory somewhere between 3300 and 3400 (not tried 3350). This is at stock voltages, still haven't bothered to flip the switch yet.

Do it! There are many reports of the 2nd BIOS adding a TON of overclock headroom, the 2nd BIOS has a much more optimized profile for OCing in addition to possibly preventing kepler throttle (the 70/80c throttle!).

Also Don I see you're still making friends at the EVGA board 😀 I guess some don't consider that EVGA had 2 classys on sale while MSI has gone through hundreds on newegg...

Ok, I am doing more testing on my card today. It seems to be 3dmark11 stable at 1,300 MHz using the second bios. I am currently testing memory adjustments now that I have found the max core. I am using auto fan speed by the way.

Once I get to what I think is ideal memory I will post my new score and make a YouTube video of the run and show what afterburner and gpuz show during it.

Wow! That is one huge card! ASUS GTX 670 DC II looks like a tiny little card in comparison 😱

Yea it's huge but it cools like a beast 😎 I also like the blue led's since they are subdued instead of blinding. Gives my case an aura :awe:

My overclock was done on the stock bios. I'll see what the other can do later.
 
Yeah, previous poster was right. Cpu or something is holding you back bad. My only run so far was 10100 something. I can't post a compare link as I have the Future Mark system info bug that reboots my pc while scanning system. I have to disable that to run the benchmark thus it won't allow me to upload.

Bug described in detail here. Anyone have any ideas? Nothing has worked for me so far.

Voltage only does so much with the GTX 600 cards though. It's well documented by modders who have tried it that you can get big boost clocks but the performance difference isn't there without also getting big overclocks on the memory which would be the limiting factor.

just from looking at some people are hitting with the ln2 bios.

it gives 1.25 volts and poeple are hitting 1300 on the core. that's good, but not uberwtfbbq good.

Asus DCII volt mod GTX 680. 1.35v 1406 Boost, but "Yes it does look like bandwidth is an issue here. I stilll get improvements the higher I go, but around 1400MHz, more core speed returns a negligible increase. VRAM is topping out right around 6900-7000MHz before I get crashes or errors."
 
Yea, I haven't bothered over volting the VRAM or PLL yet, just plain core voltage. Real life stuff in the way lately. Soon, and we'll see if there's any use for it or improvement.
 
If there's a voltage that allows higher memory clocks, I bet it'll help quite a bit up to a point where the 256bit bus will be the limitation.
 
Yea I thought I had the right resistor for it, but that VR wasn't able to give any less than 1.9V at max resistance :thumbsdown: slight miscalculation lol.

Needless to say, that's a bit more than I wanted, but I have a few other VR's I ordered that will do the job. Just have to find the time for it. I'm not going for Kingpin insanity levels, after all if I fry my card it's not like I have a supplier to give me another tray full heh.

wow, even at lower clocks than my 670, the lightning trounces the power edition. my oc'd FPS was 62.4, you pulled 67 with lower clocks. Starting to wish i paid the extra money for a lightning.

EDIT: why is Unigine recognizing your Lightning as a GTX 480?

Honestly I have no idea why it's not picking up the GTX680 as the primary GPU. I thought at first maybe I didn't have the latest version but if that was it you'd think it would say "Unrecognized Video Adapter" or something and mine does say V3.0 and that looks like the latest. I still have a 480 installed as a PhysX card, that's where it's pulling that from. That will be fixed shortly....another Lightning is on the way. 😀

Yeah when I had my 9600GT installed for physx it would read my card as a 9600GT and tell me it doesn't support this or that should I continue. lol
 
The secondary BIOS opened my card up a little bit, it's now stable at 1302MHz core, +400 (6804MHz) on the memory. I tried 1325 and +500 and that resulted in a crash, haven't tested between those variables yet. If the next version of Afterburner has further core and memory voltage adjustments this may become interesting as I think the memory will stabilize. The higher settings aren't crashing outright, they are making it a good ways into the benchmark and heat isn't an issue, the card has yet to hit above about ~60.
Ohh, flipping the BIOS switch oddly fixed the card detection issue as well. Now shows properly as a 680. lol

I got in a second run at 3DMark, since I can't use the compare function I don't even know if it's a decent score or not. Picked up about 800 points though.
