Message 25232 - Posted: 25 May 2012 | 14:00:33 UTC


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?

Yeah, I've run a few of those PAOLA's but none took longer than about 15 hours (Task 5416553). The researcher introduces them in her thread "3EKObis another conformation". A couple of recent messages in "New task on long queue, significantly longer than traditional tasks" mention results.

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

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!

It might have downclocked to ~100MHz, going by the GPU run time.
Prefer Maximum performance from NVidia control panel is recommended.

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.

It was at the 25% setting, reset it to 0. ..

The choppy nature of the GPU load graph remains:



Currently running Name 31zx54-MJHARVEY_MJH120523-0-5-RND3527_0
Workunit 3447296

Progress 57% at 17:45, to go est. 14:53.

. . . better, but still apparently running with the handbrake on. BTW enjoying learning these things. . . .

Please, any other ideas?

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.

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.

Checking Task Manager/Processes, the CPU load from the acmd.win.2352 is almost non-existent.

No sign that I can see of anything else running on the GPU.

This might help diagnose this issue:

I time share this with my game playing son, is there anything he could have done with the permissions, etc. that would screw this up?

I have crunched about 20 long GPUGrids in normal timeframes in the past month and now it seems like I'm winding out in second gear. . .

I went to the Nvidia control panel and tried to set back to defaults, but I might have missed something.

I have been to power management and overridden auto display.

Could there be some issue with M$ Vista?

. . . or with BOINC client version 7.0.25 for windows_intelx86?

Went to the Nvidia site and downloaded System Tools with ESA Support 6.05 but have it hung up with Data Execution Prevention.

Got to the Turn on DEP for all programs and services except those I select:

I can't seem to find how to get the NTUNE, NVMonitor and System Update added to the list.

Help anyone?

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.

Yes, and he suspends activity to make his BF3 run better.

Right now, I'm running Einstein, and this is my GPUZ:



. . .the GPU Load is fuller, but still choppy.

My next move is to do a dustout.

Is it really a PCIE1.1 motherboard?
Perhaps it's just not up to the rigors of feeding a GTX570, though it should be a bit better than that. Guess it depends what else is plugged in.
Anything not installed in device manager?
Maybe there is a chipset update for the motherboard or a Bios update to make that board work better with a Fermi.
Have you got Aero installed/enabled per chance?
Does the GPU crunch when the user is active?
- Also look in task manager to see if some process is starting and stopping repeatedly, search engine or antivirus...

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.

Looks like a good dustout has helped much. [running a long GPUGrid - roughly 3% in 20 minutes]

Your earlier posts show GPU temp at 66°C.
I would still suggest you increase the GPU fan speed so that the GPU temps are no more than 70°C. 82°C is a bit high for long term crunching.

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.

I am only an advanced beginner as far as the tech goes, but the download was slick and easy, set fan speed at 65% to get the GPU temp in the mid '60s.

Currently running I2R60-NATHAN_RPS1120528-0-166-RND5857_0 Workunit 3457153

so far, almost 22% in 2:50. . . on track for about 12 hours.

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.
