	Help, there is a outstanding performance on cuda fermi wus, but there is a noise comming out of the graphics card. And there are malfunctions in my display over vga output on the GTX 670 from asus. Can u fix that, or what have i to do to make it funcionaly right ? Using nvidia 301.42 WHQL drivers under XP. Got u the same failures / errors on ur card ? Greetings from germany ____________

	at this time theres no damage to the card, i stopped processing the cuda_fermi wus. But when i start them, there are heavy power and usage differences continuasly. They stop when i stop the wu. Temperatures are fine at 68-70 °C. ____________

Temperatures are fine at 68-70 °C. How big/new is your power supply? The GTX 670 will draw about 170 watts. Get GPU-Z (or similar) and use it to look at your card's voltage, then start a SETI WU and see if there's any difference. If it drops, you probably need a new power supply. ____________

	450W Cougar at 360watts out of the wall, must be 1 year old. Using nvida inspector. ok, its POWER (%) and GPU usage that have heavy differences, but theres nothing change on the voltage. Dont want to blow up the card, GPU Grid and Milkyway running fine, but there is the same effect on cuda_32 wus on project "Collatz Conjecture". So i stopped them all too. ____________

	Hmmm.... EVGA recommends a MINIMUM of 500 watts with min. 30a/12rail. for their GTX670. You may be a bit underpowered? ____________ Now a proud GPU Users Group 10.1 percenter. Yes Tron, all your base are belong to us! Volunteer idiot. ********CAUTION! competitive jerk************

	Maybe thats the point, http://www.cougar-world.de/produkte/netzteile/cougar-a.html i got only 20 to 22 Ampere per rail. hm think on that. I´ll try my 750 Watt Corsair then. ____________

	S@H certainly stresses all components of a system. If you have a 450W PSU then that will be sitting at the very top of its capacity much of the time - its not just total power, but you need enough power on the 12v rail as well. As Rus says, 500W is the minimum for a 570, and then only one that is capable of giving a solid 30-35A on the 12v rail - I went through several PSUs with my gtx460 until I learnt that lesson :-( As for the sounds and visual artefacts - if the GPU is a bit short on power they can make some strange sounds, and will produce some interesting visual effects (my "best" event was a green and purple 60/70s psychedelic rendition of the Mona Lisa.... - moments before the PSU let its smoke out.) ____________ Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe?

	So i will change the PSU thinking on that, as soon as possible. Dont wana loose the 450W Cougar. So i am better stop crunshing and do this first. ____________

	cuda fermi ... GTX 670 ... Using nvidia 301.42 WHQL drivers under XP. On a separate, but related note - make sure you stick with that combination for the time being. The next generation of drivers, at least in their Beta test form, cause the stock cuda_fermi application to fail on Kepler (6xx) cards. You're fine for now, but check again here before upgrading any software. GTX 680, NVIDIA drivers 304.48 (beta), CUDA 5.0 lead to Computation Error

	ok i changed the power supply , now there are 62A on one Rail i think. hm, pressing all my thumbs i have , will now continue crunshing. Wait a wihle and then getting some cuda_fermi wus up again. Hope it wont blew up. Edit: I AM HAPPY NOW ! No more noise , no display errors so far. The man with the guess on the PSU were right. THX , happy crunshing :))))) ____________

	The reason you need to over-spec the PSU is that it's power rating is the total of ALL the supply rails. So maybe it could produce 450W IF you were drawing the max amount of power from ALL the rails. But under normal use things aren't balanced this evenly, every different combo of hardware will draw different levels of power, with those big graphics cards drawing heavily on the 12V rail. Doesn't matter if you are only drawing 50% of the rated power on the 3.3 and 5V rails, if you are at 101% on the 12V (or any one of the rails), bad things happen. Ian

The cheap ones often fail to provide a fraction of their claimed rating even if they could provide the maximum for all rails at the same time. ____________ Grant Darwin NT.

	<automatic door> Glad to be of service! </ad> ...another of those self-satisfied doors. Don't get me started... We had a new lift installed this summer, supposed to take seven weeks but it was twelve weeks of me walking up and down three flights of stairs several times a day before it was available. All blue LEDs, bings and bongs and a female voice: Going up The doors are now closing Please mind the doors Third floor Doors opening Please mind the doors Doors closing... etc. I'm tempted to make a video of her/it calling at all four floors. I've asked for the voice to be replaced by Marvin the paranoid android, but no luck yet. ____________

	The quality brands will provide what they claim, and often more. The cheap ones often fail to provide a fraction of their claimed rating even if they could provide the maximum for all rails at the same time. Even the good PSU's will have separate max ratings on each rail. The difference is that they will actually produce what the label claims. But that 650w supply may only be able to supply 400w on the 12v rail. Try and run 2 of those cards and you get up around that 400w on the one rail, and even though the whole rig is only drawing 500w, the power supply dips out. I agree totally on the cheapo supplies though. The ratings can vary between "optimistic" and "total work of fiction" :-) Ian

	This thread explains why I had these problems with a Nvidia 560 a few months back... it failed with the garbled display as mentioned by the OP and my first thought was "oh no, the graphics card has failed" but then when checking things out it worked in another computer... and the strange thing was that the 560ti that I swapped it with didn't have that problem... I guess the PSU is coping ok with the 560ti. Rule of thumb: If you are crunching on a GPU, then invest in a decent PSU and pay attention to the 12V rails... some cheap PSUs that claim a high/reasonable wattage are actually quite low on the 12V rails. ____________ Brian.
