A limit is something different than a problem.

The limit IS the problem, A bad overclocker or a locked card is the same if theres no way around.

2.8GHz doesn't mean anything if it can't produce commiserate performance for that clock (see record BD clocks). Could be why they didn't show any bench performance at that speed. Or they could be sandbagging for some reason? At any rate, everything I've read says that ln2 drops off a cliff at 2.5GHz and that nobody should be expecting real world air/water clocks beyond 2.2GHz on any 1080 (which, let's face it, is still pretty amazing performance).

I don't understand the whole 1.25V limit...Is this some theoretical number that people are throwing around as the max for Pascal? None of the current offerings even come close to this. Are we talking about shunt modded cards? My card only ever pulls 1.05V with Afterburner and 1.09V with EVGA precision XOC. I have non OC version thought I was stuck with 1.05VDDC and I notice that the OC version in reviews is showing 1.093VDDC which I assumed was how they reached the 1936Mhz boost clock and that it was bios related.

I wasn't able with MSI Afterburner -my normal go-to software, to get stable above 1974Mhz Boost with 120% power, 92C Temp limit at ~60C but switching to EVGA PrecisionXOC got me up to 2050 same temps and 1.09V Max VDDC. Interesting that one program will allow more Voltage than another...I thought it bios locked.

I bought the card due to the extra power as I will have it on water shortly I"m just waiting on the block, If someone could please tell me how they are getting 1.25V I would be very greatful:) Has anyone successfully flashed an OC bios to the non OC Strix? I would love to know how.

The 1.25v limit came from a single person who was/is a decently respected overclocker saying they volt modded their card and it would crash if the voltage was set anywhere above 1.25v. Since then the community who thinks they are the smartest people on earth have decided there is a complete limit at 1.25v no matter what, despite other overclockers not having any issue with going above that voltage. It is just people keep saying the same stupid thing over and over and over and deciding it is truth because they heard it so many times.
For 99.9% of people who will own a Pascal GPU it doesnt matter at all one way or the other because the architecture, just like Maxwell, doesnt scale well with voltage anyway and the new, more dense node has even more of a heat problem if you raise voltage. So really everyone on air and water is limited to about 1.15v~ or so as the practical limit for what their cooling can cope with.

All Strix products are voltage locked on the GPU side.
post #126 of 128
Thank you, I thought it must be something like that. Meanwhile I hope being as this card seems to be the only one that has flooded stores without problems of availability more OCers will buy them and we can get a guide on voltage mods. I personally would try liquid metal but my card sits vertical. I do have plans to cut the PCI slots in the case out and turning it then using riser card to turn sideways...just a custom look mainly but anyway, thank you for the thorough response. Much appreciated!

Voltage mods here:
https://xdevs.com/guide/pascal_oc/

And I have a guide in the Nvidia section for doing CLU over the resistors, but as you said with a vertical oriented card you have to be a lot more careful. CallsignVega, Criminal, and others have done CLU to their cards and they run vertical and have had no issues. You just have to use a very, very light layer over the resistors. Of course, then the mod doesn't help as much with it being so thin, but at least it gets you another 10-15% power target limit so that's something.

Awesome!thank you so much!! My wife will be gone all week, so its modding time. Couldnt be more perfect;)
