There is nothing magical about the bios that would give another 50mhz to the core besides the obvious fact that the cards are now getting more voltage.
It could possibly be that a few 680's were already peaking out at 1.21 while most others such as myself were stuck with 1175vc.

I have the 1.21v bios for my Asus card and for kicks I ran without the hotwire. I measured 1.23v load with my multimetre.

Thanks, that is interesting info. thumb.gif

Its already been verified with voltmters by others on various other forums. I suspect you know this but software doesn't report proper voltage on the GTX 680 (sans the lightning) it only reports what the BIOS lists as vDroop max. So if you go over that on such a board, even if you mod your card with EV Bot on a classy it will report 1175mV. Again, software doesn't report proper voltage. It is pretty cool that a BIOS is benefitting others, thats great for them. Who knows what the actual cause is though, there are a lot of power related parameters in the BIOS.

GPU-z reports 1.21V on my lightning when its at 1.37V.

Of course, since you have so many 680s you could easily just try it yourself by using a voltmeter on an unflashed 680. Try it!

Have you tested this with the old BIOS? I know other ref boards go up to 1.2V at max vDroop. Some of them do, anyway.

Well what ever it was, I love it. I am, imo, having a hard time believing that it couldn't read 1.21v before but after the flash it is now? Thats the main part that does not make sense to me, but oh well.

Thats awesome dude. thumb.gif Whatever the cause, its pretty awesome that you guys are getting better overclocks. Join us in the 3dmark11 benchmarking!

Thats because GPUZ does not read anything beyond 1.21vc. Up to that point however it reads vcore just fine.

There's the sarcastic comment that I was expecting, for a minute I was getting worried that you might be sick or something. rolleyes.gif

Thanks for the info guys. I may try the modded reference BIOS when I feel a little adventurous. I kind of want to try something on my card beings it is not quite the normal 680. Just about every other card out there will actaully boost past it's set boost speed (like getting >1100mhz boost speed instead of the 1058mhz on a stock card). My card will only boost up to what I set it to. So, as stock my boost is 1124mhz. It will not boost higher. If it OC so my boost it 1200mhz, it will not boost past 1200mhz. Not saying a different BIOS will in fact make it boost higher, but I still think it is wierd that my card is about the only one out there that I know of that boosts to exactly what I set it to. It does make it easier to OC though beings I know exactly what it will go to.

Thats because it wasnt at 1.21vc before the flash, it was 1175 regardless of what certain know it all's around here would have you to believe.

I knew you'd respond with this type of stuff. Of course i'm lying. Obviously you could easily test this stuff with a voltmeter or ask the creators of GPU-z. They have a forum. thumb.gif And obviously i'm making up the bit about other users who tested this months ago on his gtx 680 and found 1.21V. Whatever dude whatever.

Now whether this is limited only to certain GTX 680 ref boards -- that i'm not certain of. Seems unlikely since nvidia manufactures all gtx 680 reference boards.

I'm happy that others are getting better overclocks, good on them, whatever the cause is thumb.gif
