Common memory offset I can use in SLI is +500MHz, on individual cards I could use +550 or +575 respectively.
I use water cooling blocks on both cards as I 'm fed up with annoying fans noise and those mounted on GPUs are VERY annoying. with my hot ambient room (27C on average), both GPUs stay below 50C during daily gaming, below 55C during stress testing. yes they do get throttled down under severe stress, it's not temperature related, it's throttling related to Power Target levels, that's how Keplers work - when they reach certain area below Max specified Power Target, they will throttle the clocks temporarily.

Yeah I have to say, the stock fan on these reference cards is unbearable in terms of noise. But shouldn't the cards stop throttling if you raise the power limit and keep temperatures in check?

Anyway thanks for the heads up. I'm lucky enough to have a lot of hardware passing through my hands, so I'll try a few cards more just for the hell of it... It should be reasonable to expect at least a 1300MHz+ chip at some point or another. Wish me luck!

yeah, exactly what I mean ... 1 person ... among how many? a few hundreds at least wink.gif

it depends... on stock BIOS and latest 4B revision, both cards can do clocks near 122% Power Target and no throttling in benchmarks or gaming, while with vmodded BIOS (same 4B revision) and PT set to 150% they WILL start throttling down above 140% actual in benchmarks (e.g. Heaven 3.0). in both instances both BIOSes will cause power throttling under severe stress, e.g. Furmark with Dynamic Camera and FXAA enabled at max full screen resolution (1920x1200 @ 60Hz in my case).

either way, those 670 cards are very strong as they are even on stock BIOS biggrin.gif .. in older games they run at half whistle in SLI since there is not much to do for them wink.gif

good luck with binning! biggrin.gif

Under stock BIOS I'd also end up around the 122%. Got pissed at how low it was and considered moving to AMD before I stumbled upon this thread. Thank god nVidia overclocking isn't dead yet biggrin.gif It's a shame there's no voltage control, but I'm pretty sure 1,3V+ is gonna have people kill their GPU's. The software limit was already at 1,2V during the Fermi days and those were still made on a more robust 40nm process...

What BIOS did you flash to end up near the power target limit? The one that I flashed raises it so much that the card hobbles around 98-99% power limit at 1254MHz. Doesn't stop me from dragging the slider to 112 but it seems pointless. And now that you mention it, the card runs at completely different (lower) clocks in Furmark than it does in game. I'm using Heaven now to tune the clocks while the card is being stressed, then try some 3DMark 11 and Far Cry to confirm they work for extended periods of time.

Most drivers nowadays detect Furmark as a danger to your GPU and will throttle them. thumb.gif

Well this is strange guys there must be something wrong on my card the gigabyte 670 windforce, i see even on first page there's a screenshot with gpu-z/precision etc and the guy has 1300 mhz with 129% of power or so.
My card even after moded bios stays at the same 70-80% even if voltage increased,im ussually running Unigine and BF3 at around 70% stock and with bios mod + 500 mem my power was hovering around 80% could this be the reason why it doesnt OC more than factory 1170 mhz?? if so how do i unlock it , if the moded bios doesnt do it and i tried increasing it with afterburner but the same result.So whats going on here.


Edit: Forgot to mention i have a poor PSU but with OC cpu/and gpu testing it never even overheated or make problems at all.PSU is Recom M500 watts:o
Could it be that is has enough power but the Psu rail voltages are too low when i try to increase power/OC and the card doesnt allow it to go further??im not very good at this.I was actually planing to change the psu soon after i bought 670, but then i saw its rock solid and not overheating during tests just a bit warm so i kept it.

1.3v here, still going strong! smile.gif

Monitor your TDP in Far Cry, i assure you it will be higher than in Heaven (given you are using demanding graphics settings). Just crank it to the max, no reason not to.

Your PSU could very well be the cause of your problems. A cheapass Recom brick is not going to enjoy your overclocked 670 for long, and the risk of it overheating has nothing to do with a simple matter of capacity! I'd definitely recommend you to invest in a proper PSU upgrade before you put your expensive hardware at risk like this. I just don't get why so many people run 400 dollar graphics cards with cheap power supply units, be sensible please. You wouldn't go around trying to make a Lamborghini run on crude oil then complain when it's giving you issues, right?

Got it. And how did you hardmod your card? What type is it and how are you cooling?

I have to say my EVGA GTX580 started to degrade running at 1,23V after seeing only 3 or 4 months of use, despite being liquid cooled and never seeing temperatures above 40°C. It ran 1000MHz 24/7 at first but I ended up having to settle for 950 to stop getting driver crashes that I previously wasn't having.

No hardware mod, the Power Edition card supports overvolting tongue.gif However, i decided to only overvolt to 1.26, since the temps went mad (and so did the noise) at 1.3.

Ah, cool. Too bad the PE cards are non-ref, my waterblock won't fit them mad.gif
