Oh you can? Alright might update my precision X then. Yeah 1.213 is VERY tempting. Just a little scared of having a $500 paperweight with 3 fans and a heatsink attached to it. hehe, we'll see. Might try to squeeze the most out of my stock BIOS and see if I decide to get the modded one. Think I might start from scratch with 0 offset and raise mem clock to highest, followed by core clock, that way I get the most mem clock. Seems to be more important for this Kepler card than core clock.

Mem clock IS a big thing cause we're limited by our 256bit bus, so you need more mhz to compete with a 384bit 7970 for example...I run it at 7800mhz cause I'll be using a 1440p monitor soon and I'll need more memory bandwidth for gaming. So far it works great.

As for the voltmodd, I wouldn't run at 1.213v for daily use, but that's me personally. I only run my overclocked settings for benching...Also, the no boost thing, not sure if it'll be good for the card (at least for a reference model) in the long term. I love that feature cause it increases benchmark scores a lot.
For me is at close to stock volts and speeds as possible, or the max possible oc using stock voltage, but only cause I'm really fund limited.
There's plenty of people here that use 1.21v regularly with no prob whatsoever, so ymmv.

Definitely fund limited if we're talking $500. And I don't really bench, I really just enjoy overclocking for more frames, even if it means 5-7fps only. I get your point with the 256 bus. Will probably see more fps by improving mem clocks than core since the core is more than enough for the limited bus.

Guess my next question is what would the lowest "acceptable" core speed be before seeing a negative effect on frames? 1205MHz minimum probably or should go higher/lower? I feel you can get higher mem clocks with less core, but IDK how low my core speed can go before having negative effects performance wise.

Also I think I read somewhere that NVIDIA clearly stated that overvolting beyond their stock voltage would drastically reduce the life span of the GPU. Think it was in this thread.

Yep, I wouldn't push it more than enough...1.213v is not terribad either, as long as it's running cool.
1200mhz core is plenty, try to get 1250mhz core and 7ghz vram, that sounds doable.
Thing is Nvidia apparently launched their intended mid range gpu as the flagship this gen, and it makes sense cause of the naming scheme, that the gk104 gpu is an overvolted and overclocked mid range part. (That would explain nvidias's concern too)

Maybe with a modded BIOS I can do 1250/7000, but right now I'm at 1205-1215/7000. Also gonna disable boost once I update EVGA Precision. 70 degrees at full load right now so I guess that's not all that bad, honestly it does feel like the chip can handle 1.213v easy, I can maybe give it a try when I get some free time.

Yeah, you can always flash and run it with stock volts, but you'll get a higher boost clock from scratch so you can dial back the offset and lock boost at say 1202mhz.

I just unlocked my Gigabyte Windforce x3 card and i was able to squeeze 40mHz more out of it. I have some questions:

My memory is set to +765, and it's stable. Is this safe? most people put it around +400

When I unlocked my card, the power target in MSI afterburner would only go to 125%, not the 145% everyone else has.
Should I use the "mod.rom" from this video and flash it with the OP'ers method?

BTW i have a full cover waterblock if that helps.

Give us the actual clocks shown in Precision X's or AB's graphs...
I'd reccomend you to try Precision X 3.0.4 or something, it has a cool lock boost freq function. Useful to determine your max stable oc and benching wink.gif

I switched to PrecisionX and ran another Heaven 3.0 at those same clocks, got 1309. Here is a screenshot of GPU-z and PrecisionX
