I'm crunching with a 560-448 and have been doing the long runs in 10-14 hours.

. . . I'm now crunching 36 hours on one and barely 1/2 done.

Anyone else having experience with an apparent marathon?

No unusual run times for me with my 570 and the long queue. Which WU are you talking about?

Has your GPU downclocked? My GTX460 was completing the 3EKO units within 24Hrs.

I don't think so:

Finally finished in roughly 52 hours.

Going to Nvidia 301.42 WHQL driver.

. . . taking a break, will crunch Einstein for a while.

That definitely looks like your 560 downclocked after erroring out a WU. Sometimes a GPU clock will drop to around 405MHz if you suffer a ACEMD crash and it needs a reboot to get back to the correct speed.

If you open up GPU-Z again, click on the sensors tab.
take a screenshot and post that to the forum.
I'm certain that the other posters are correct and that your card
is running at half speed for some reason.

To simplify, Graphics cards have 3 'speeds'

1. idle - when they are doing nothing, generally around 50Hz
2. 2D - not to be confused with a 2D picture or anything. This is half speed, when under moderate load, or if the driver has crashed, it limits the top speed of the card to this - normally 405/450Mhz to protect it from damage
3. 3D - again, not to be confused with a 3D picture, this is maximum performance mode - for your card, that's 765Mhz.

If under the sensor tab, you see 405/450 next to the GPU core clock reading, you know your driver has crashed.
Easy fix, just re-boot your computer.

There is a bug with the current nVidia drivers that causes this. You need to go into your power profile in windows and disable the automatic screen shut-off. Just remember to turn your screen off manually and you should be good.

IF you need specific instructions, post back and I or someone else will be able to direct you.

Crunch on!

Seeing the screenshot ..... a thought .... the GPU has been running at a fair speed, but the graph alongside the 0% with the even on/off stop/start nature of the output graph could indicate the "while processor useage is less than" option in BOINC Local Preferences has returned to a 25% setting.

It should be set to zero percent to stop it kicking in. Worth a quick check.

Some of these PAOLA workunits take a long time. I have over clocked 570s and 580s and they take 40,000 seconds. Is your CPU distracted at all? I noticed my CPU based projects required far more time once these workunits started.

Can you check to see if anything other processes are consuming your CPU or if you CPU is maxed at 100% maybe you could overclock it a bit.

Please let us know what you discover.

Note: Please don't use driver version 295 or 296! Recommended versions are 266 - 285.

Treat my next comment with great caution, its a long while since I ran NVidia cards - however the GPU Memory load at 641Mb seems a hell of a lot for a WU, I didnt think they were that chunky .... needs verifying by an NVidia cruncher, dont do anything until you get similar comment from an experienced NVidia cruncher.

It does seem high though .... maybe worth checking to see if inadvertently there are other GPU tasks running, whilst you await confirmation or otherwise of the suspicion.

641Mb is fine for these tasks here, in fact it helps make them fast. Anyway that GPU has 1.2GB, and is a good GPU BTW.

Sid, I'm guessing what you are doing, but I suggest you stop crunching on the CPU (or just use 1 core), and see if that changes the choppy graph; that's still a decent CPU but your GPU is relatively massive.

If that's not it then look at your advanced Power settings.

No issue with 7.0.25 as far as i know. Would highly, highly recommend increasing your fan speed though for starters.

Sid, or you using multiple log in's on your PC?

Whenever I timeshare my Windows 7 Ultimate, Core i3 530, GTX 480; with my grandson, and he logs into this PC with his account name and password, and then later on logs back out, I always have to do a reboot on this machine, for it will never ever revert back to it's full GPU speed. However, if he uses my default log in, then everything is fine, and the GTX 480 remains at full speed, multitasking GPUGRID, while still playing his games on line.

If it was a pcie issue I would expect einstein to look worse, not better, since Einstein uses more cpu than gpugrid. Dusting may help. At a loss honestly, give me some time to wake up and I'll post again.

Dusting may help.

Wow. If all you did was dust. Your temps dropped quite a bit!! Looking better.

Not sure on your technical background. but if you were trying to download those tools to increase your fan speed here's a link for EVGA Precision http://downloads.guru3d.com/downloadget.php?id=2611&file=4&evp=0a465c6080d2aa1be0bdf995f597acbb

Really easy to use. Once downloaded, just open up the program de-select "Auto" fan speed, and increase it yourself until you hit, as skgiven stated max 70C. I prefer to stay under this, around 60-65C. Depending on your tolerance for noise I guess. Don't crank it up all the way though, since you want to make sure your fan lasts as long as possible.

Anymore questions, just ask.

Cheers.

Did you dust the CPU too? How many cores are you using now?
82°C is a bit high for long term crunching.

That GPU load bouncing around is not right.

In your Boinc Manager, go to Advanced -> Preferences

down the bottom there is the option

Use At Most {100%} CPU time

Make sure the number is 100%.
I think it's at a lower number and that is why the usage is
bouncing.
Bad for your GPU and bad for your CPU doing that.

If it isn't 100%, change it to 100%.
Check your temps after you do - especially your CPU and it will apply a bit more load on it.

Good Luck

The permissions are set for using 100% of CPU time.

Currently running some Einstein with the GPU downclocked about 20%.

. . . temps just fine with fan on auto, GPU load in the mid 60s flatline.

Son played BF3 with it as is and didn't notice much difference.

Beginning to wonder if the CPU [C2D6700] just isn't up to this GPU.



After the SIMAP Scramble, will come back to GPUGrid and give an update.

CPU throttling makes sense actually, especially if you are running other projects at the same time.

try running GPUGrid on it's own with no other projects running - allow it full use of the CPU. If that GPU usage graph changes, you'll know it's the cpu that is crippling the GPU.

The NATHAN long runs typically take 20 to 40 hours on my GTX 260s, with most taking about 25 hours. Occasionally I get one that takes 40 to 50 hours.
