a question to those that have watercooled their reference 680s: how much of an core increase did you guys get? i'm quite curious. I can't go through 400 pages of the thread sorry frown.gif

I believe very few if any people are getting an increase in core clock from water on these cards. If you find a max core clock and can keep it under 70c on air then that is what you will get from water. Only advantage is extra cool and extra quiet. If you can still push your card but it keeps downclocking due to heat then you will see more gains.

I gained 753 points in 3dmark, thats much more then 1% (But this is only one example). But I for sure see what you mean Hokies83, it is risky and you can kill your card. The crazy few of us that are doing it and keeping it are the lab rats, if something goes wrong done the road, we will tell people to sway from it. But until then you and no one else has proof that it can kill your card. Sure past examples of other cards and architectures have shown that heavy volt modding can kill a card, but a little? I doubt this. And many others can say how they still are running 480's, 570's 580's 6950's 6970's 7970's etc with increased voltage running just fine.

Typically, most reference BIOS' report 1175 as that max even though they may go higher (and they have been tested to go higher with multimeters.
The only way to see max voltage is with a digital multimeter. Software does not report proper max voltage on the GTX 600 kepler in all cases, especially with over voltage.

MSI lightning owners have software reporting 1.175 or 1.21V when they're running at 1.4V. Same with the EVGA classified. Reference boards can and do run 1.21V but software will report either 1.175V or 1.21V depending on which BIOS you're using, FYI. Like I said this has been tested a long time ago, reference boards reporting 1.175V when they're running 1.2
have a feeling the reason overclocks go up is because this new BIOS raises the core voltage and thus the effective GPU Boost voltage that Kepler adds dynamically in the background (that GPU-Z, MSI Afterburner and other software programs can't detect). Let's say the stock card goes from 1.175V to 1.20V with GPU Boost active in the game as blackened23 mentioned. The new BIOS puts the core at 1.21V and suddenly Kepler dynamic GPU voltage boost might be pushing the card to 1.23-1.24V in the real world. The problem is without a multi-meter this is undetected and people think their card is only using 1.21V. This is why overvolting Kepler can be so dangerous on air. You might apply 1.23-1.24 and end up with 1.25-1.27V.
For example, HardOCP's MSI Lightning had a default voltage of 1206 mV and they applied a GPU voltage offset of +93mV. That means at most this card should be using up 1299mV, but in games with a volt-meter that went to 1318mV. It seems Kepler is adding a little bit of extra GPU voltage for GPU boost but it's just not showing up in software.
.
Stock these cards are doing 1.21 Software is just not showing it this has been confirmed with a volt meter..
I did not see the post but they said somebody reported the use with a volt meter and reported 1.23 volts.. I do not know if this was the volts with the max boost clock are not.
When it comes to overvolting a Gpu 00.1 to the core can kill them.. Volt modding a card that has it locked for a reason is very risky.. and from what the people are reporting 20mhz-50mhz at the max some are not getting anything at all. it is really not worth the risk imo.
Then Again it is your Gpu and your risk so if you feel the need for that 1% performance have at it. thumb.gif

Thanks for the info! thumb.gif I never knew kepler was so complicated! Why won't they just go back to the old fermi style of overclocking frown.gif If these digital voltmeters aren't expensive, i'll go ahead and purchase myself one and tinker. I'm using the 1.212 bios on my 680 DCII. DCII has a beefier overall design. Is it safe on my DCII?

also, would it be reasonable to assume that overvolting reference 680s on water is safe? Snorkle.gif

that sounds reasonable. but i heard some stories of people getting more than 50+ mhz increase after slapping a block on it. i wonder if any of it is true.

Actually it is pretty much all gpus, I don't think I've ever seen any card that has the same voltage showing in software & on multimeter at the same time.

Might be some gain, on a 680 lightning going from air to water gained me 20mhz. Not worth buying a block just for the extra 20Mhz unless you have an old one around (I did), or plan on getting one anyway.

The ref 680s were not built to take much Abuse id be very concerned with touching voltage on them.

Now some of the non Ref designs Asus Dc II Gaaxy soc HoF The lightings and the GB SoC should be fine there built better and built to take the abuse.

Remeber guys about the nonreference cards that have beefier pcb, components ect. The actual gpu chip isn't beefier than reference and can easily degrade if pushed too hard.
