That's almost certainly true in this case. Remember the GTX470 only comes with two 6-pins, which means it's rated for a max of 225W. Yet the card draws substantially more power than that, thus if the PCIe ports are power-limited, the card is being underpowered, which will cause it to artifact.
They can provide 150W. They could provide 1000W before they melted. But they're rated for 75W. I'm well aware they don't have any more conducting rails than the 8-pins, but there's a reason both connectors still exist, they're to fix limits on how much power a graphics card draws by specification. The power draw limit won't be at the PSU end, but what if it's on the graphics card itself?

I know GPUs aren't exactly ohmic, but an 11% increase in volts to an ohmic device increases power draw by 23.5%, and that's quite a lot. If you use 250W to start with (which the 470s can use, and exceed at a push), then add that 23.5% increase and you get 309W, or in excess of. That's a lot.
Unfortunately it's an older Abit IP35-E which only has options to change the PCI-E frequency. Given your suggestion, would a glitch such as the one above be caused by a flaky or old PSU?
wow i read this tread a while back but dismissed it because you know how people are.... if it's not happening to you, it's not your problem. but I think i encountered the exact same thing with my sli 580s last night after pulling my cpu from my computer to change TIM (that's it no other change). The bios detects it as a new CPU (even though it was the same) but I had my profile saved. reload it, sucessful post... boot in to windows and the system just hard locks every time at the welcome screen like WTF?! The screen goes slightly dim for a second when it locks and eventually the hard drive spins down. When it's in this locked stated, I can power off the PC with just a quick jab of the power button, not needing the 4 second hold like it should be. Change back the mobo bios to default settings with no OC, doesn't help!.
Definitely feels like a driver issue (possibly power states as earlier described) because booting in to safe mode and uninstalling the driver allows me back in windows 7. I can reinstall the driver in normal mode but it starts locking up again. After hours of trouble shooting, I got it to work (so i thought), I go to Nvidia Control Panel and enable SLI aand boom, driver crash and then lock. Reboot and it's the repeat of the exact same issue I originally described in now allowing me back in to windows!! I'm going in circles here for hours trying to trouble shoot this shit. Then finally after suspecting one of my cards as bad, I uninistall the driver, boot back up with just one card installed. Everything seems to work fine! I'm afraid to reinstall my other 580 but I bet there's nothing physically wrong with it after reading this. But I'll try anyways.
Nvidia has let me down. I can't stand ATI CCC and how they handle custom resolutions so my only solution is to find a work around until nvidia fixes this.

Perhasps we should go back to Matrox and Voodoo cards
Well low and behold, it was exactly that! I changed the PCI-E Frequency to103 and wallah, here I am posting this message to ya'll.
Does that disable a spread spectrum clock possibly?
In that thread, there's complaints on Asus P7P55D and a EVGA GTX 460, I've got that same Asus motherboard and Asus GTX 460, no problems here. I actually see that several people there report problems with the P7P55D board and various GTX cards, 460, 470. But since I've got no problems, it's obviously not a given thing, seems random, or faulty cards.
Very troubling. A friend of mine bought an EVGA gtx 570 to put on an Intel p45 based Asus P5Q-E. Latest BIOS.
Is he screwed?
Is the silence speaking volumes here or is this just one of those stray random issues?
amd7674 in this thread had this issue with a MSI 570, while an EVGA 570 worked. I don't think its given whether the card works or not with the same MB. I've tried my Gainward GTX 570 on a p5n-D motherboard, which is supposed to have issues according to that list and my card worked fine. Your friend should just try it, since he already bought it. Only way to know for sure I think.
Haven't had any issues with my 480, then again I don't install the nVidia audio drivers or the 3d stereo driver. I install PhysX and the graphics driver only. Best wishes to people having problems. Hope it gets worked out.
Indeed.
I did some calling around about this issue. I called Maingear and I called several of the other outlets like that and I was encouraged by the fact that to a man and place no one was telling me about any serious blowback on this issue which you would think they would if this was a REALLY large scale and big time issue.
Odds favor things being just fine.
