I'm noticing a trend that seems to suggest that there's something buggy with the 560ti card as a whole, or at least insofar as its interactions with SETI/Lunatics.

Please take a moment to fill out the information below so we can help the Lunatics builders hammer out this problem. The problem will likely become exaserbated eventually as the 560ti prices continue to become more affordable for more crunchers.

1. Please list your system specs. PSU, GPU's(their make and model), OS, CPU and so forth.
2. Which version of Lunatics are you running?
3. Are you experiencing errors or downclocking? If so, please explain/expand on what issues you are having. For example your cards downclock every 1 hour and in doing so, throw an error message.
4. At what temps are your cards running at full load?
5. What clocks/voltage are you running on your cards?
6. Have you set your NVIDIA power performance to 'max performance' rather than 'adaptive'?
7. Have you disabled hardware acceleration in your web browser?

Slavac try downclocking your cards.

85°C is to much.
You find always more spikes as your wingmen therefore get invalid results.
This has nothing to do with the app itself.

Use MSI afterburner and set regular non OC speed.
If you produce valid results only you can speed up step by step.

Superclocked cards are not always 100% usable 24/7.

I had the same problem with a 450 SC card i setup couple month ago.
As soon i downclocked the cards no more invalids was produced.

Slavac,

Download the EVGA Precision tool from their website. I have three EVGA cards on two machines and use the tool quite effectively. You can control fan speed automatically depending on the GPU temp, or manually. When on automatic the GPU temp controls the fan speed. The speed is adjusted in 5c steps, but you can override and adjust the steps if desired. Or you can use the slide control at the bottom of the tool to adjust manually.

On the A-SYS (EVGA GTX460 SE & GTS250), on the tool adjusts the speed on the GTX460 SE automatically with temps avg between 37-60c. The GTS250's speed is manually adjusted to keep it below 70c. The one tool controls both cards. On the B-SYS the tool automatically controls the speed on a EVGA GTX275/GTS250 card with the temp on the GTX275 side at approx 65c.

BY USING THIS TOOL, I HAVE NOT FOUND ANY REASON TO DOWNCLOCK ANY OF THE CARDS!!

I did, but the issue I have with it is that there is no voltage control.

I monkeyed around with MSI's fan speed controller and now have both cards around 80C at full load.

If you are trying to OC the cards, look at EVGA's OC SCANNER, it may give you what you want and still keep the temps below 80c.

At this point, I'm trying to unbork these cards (i.e. keep them from downclocking). Once that's all sorted, then I'll worry with OCing them.

Have you been able to get the cards completely back to the "stock" (as purchased) speeds and voltages? Did you still get downclocking?

Yep, especially with stock voltages.

Yep, especially with stock voltages.

What happens when you return the frequencies to stock nVIDIA spec's?

Quite a few people have found out that doing this with factory OC cards has eliminated errors. ;)

Sounds like a defective card on your part based on responses in the thread.

1. asus p5kpl-cm mainboard. intel e5200 stock 200x12.5 im @ 333x10.5 for 3.446ghz, ocz fatal1ty ddr-2 1100 6-6-6-15 ram. 2.25v btw. galaxy 560ti GC edition video card. psu is some junk antec 500w something or another thats going to be replaced in a few days because the 12v rail cant provide enough juice for this rig and i cant o/c past 3.4ghz AND o/c the video card without the pc turning its self off. i can do 1 or the other. not both. yet...


2. Which version of Lunatics are you running? newest
3. Are you experiencing errors or downclocking? only if i have the gpu run 1 wu at a time. as long as its set to 2 @ once, and i dont error out from 12v issues theres no downclocking issues.
4. At what temps are your cards running at full load? 50c
5. What clocks/voltage are you running on your cards? had to downclock just to get it to run. 734 core, 1468 shader, 1600 memory and 0.85V
6. Have you set your NVIDIA power performance to 'max performance' rather than 'adaptive'? no. that shouldnt matter, and from what i can tell by messing with it, it doesnt matter.
7. Have you disabled hardware acceleration in your web browser? y? no...



i feel i should explain better. my power supply doesnt have enough amps on the 12v rails to let me o/c both the fsb, cpu and video. only way i can do it is when i temporarily hooked up my lab power supply to the 12v rail to supplement the computers power supply with extra amps of 12v goodness. then i oc like mad and do whatever i want and its rock stable. but this was only a temp solution so i am stuck for now until payday when i can get a bigger better power supply. as it is rite now i am struggling to keep afloat using whatever i can get out of this supply. my 12v rail is at 11.65v and when it goes to 11.63 my pc shuts off. why do they use the 12v rail for video cards anyways the gpu and memory run at like 1v or something. they should just use the 3.3 or 5v rail...
all of the video cards made fairly recently use a huge mount of 12v power it seems. maybe i should hook up my jumper cables and see if that helps. freakin video card needs more power to run then my car does.

...

At 12v 75 watts is 6.25 amps, which can be supplied through reasonably small and flexible wires and simple connectors. At 5v heavier wiring and better connectors would be needed to supply the needed 15 amps.

                                                                Joe

That's interesting. I'll have to devise some theories how that could happen.

... all of the video cards made fairly recently use a huge mount of 12v power it seems. maybe i should hook up my jumper cables and see if that helps. freakin video card needs more power to run then my car does.

hehehe, yeah, I never thought I'd see the day when I installed a PSU capable of 100 Amps on the 12 Volt rail (which I did yesterday). I should have taken the hints from nVidia's naming scheme I guess.. Tesla & Fermi.

Separate but semi related issue: Anyone with a fast (high sampling rate) digital oscilloscope around ? My new PSU has ferrite chokes on the PCIe 12V connectors at the GPU end. I take that as a big warning sign that GPUs might be capable of trashing the 12V rails beyond load regulation limits of some power supplies, and wouldn't mind seeing comparisons of high-end Vs borderline PSUs, with & without chokes. If those things are there for good reasons, then it opens yet more cans of worms that'll need figuring out eventually.

Or it's just more advertising gimmickry.
Chokes down there will just stop electrical noise (of the appropriate frequency) from the video card making it's way back into the PSU. Or any noise picked up in the long power leads from getting into the video card.
Or most likely, it looks impressive.

In any case, it can't hurt....and Corsair must have had a reason for adding them other than looking cool. Ferrite is pretty cheap. Might have to do some Googleing on this to see if there is any other info out there.
