The last 2 WU have had a wall clock time of 25 & 30 hr.

They used to be around 8 to 9 hr

Running XP-Pro 64
Boinc 6.10.6
GTX-260
Cuda 2.3
Drivers 190.38

Is this what you are getting?

The next two that I have Downloaded are doing the sane thing

it looks like that power managment is kicking in.
A board is clocked at 0.60Ghz. Not quite what it should be.
Maybe updating the driver would solve this.

Also you have a linux machine with an old driver which you should update to a more recent one. At least 185.xx

I have just received one unit with an expected time of 25:40 hours:min. Normally 8-9 hours in this computer ("IQS").

for the expected time you should not worry about.
We have increased the expected flops to be closer to the real value, so the client thinks it will takes longer. It will adjust in a week or so.

Note: Moved the GPU from a Linux box to a XP Box

So I upgraded drivers from 190.38 to 190.62

Wall Time 24:06
Run Time 25 min

I suspended the current WU and started This WU with the upgraded Drivers

http://www.gpugrid.net/result.php?resultid=1306052

What else can I do to get back to the 8-9 hr wall clock Time?

Thanks Steve

Wall Time 27+ hr

Driver 190.38 for 1st 18hr
Driver 190.62 for the rest

To bring the Wall Clock Time down Should I roll back to a Driver 185.xx ?

I am Lost as to I should do?

Thanks for your help.

Message 12919 - Posted: 29 Sep 2009 | 18:40:55 UTC

My first thought is that you are getting the down-clock bug as noted by PoorBoy...

Second, that the 6.6.20 extended run time bug is back ...

Or both ...

Is it happening consistenly? or just once in awhile?

The first may be solved by lowering the driver version to the lowest acceptable. I have lost track of what that is sadly ...

The second usually can be "cured" at least momentarily by stopping BOINC completely and starting it up again. I do *NOT* know that this is a hidden manefestation of 6.10.6 but that is a known bad version for other problems. So my FIRST suggestion is to up to 6.10.7 (leave the later versions alone they won't help with what we do on GPU Grid (yet)).

Last 4 WU

I have tried that..... No help at all

I do *NOT* know that this is a hidden manefestation of 6.10.6 but that is a known bad version for other problems. So my FIRST suggestion is to up to 6.10.7 (leave the later versions alone they won't help with what we do on GPU Grid (yet)).


How would I do that ....... setup different directorys for 6.10.7 or just uninstall boinc 6.10.6 and install 6.10.7 ?


And what about cuda keep 2.3 or should I go back to 2.2 or 2.1?


I have a bunch of Colatz-Conjecture WU to finish fist then will try GPUGRID again

Thank for your advise Steve

Try one thing at a time. First I would install 6.10.7, I never uninstall, but, if that makes it better for you sure...

If that changes nothing, then look at the drivers. I am running 190.38 and 190.62 I think on XP 32 ... but everyone seems to have different luck with the drivers so it is hard to say what is the best idea there ...

WU http://www.gpugrid.net/workunit.php?wuid=824961

Wall Time about 8 hr

8-9 hr wall time is what I started out with. Then it jumped up to 25 - 30 hr after upgrading. With GDF & Paul's help I am back to 8+ hr on the first WU.

My current setup is:

CPU: Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz (2 cores)
GPU: NVIDIA GeForce GTX-260 (895MB)
Drivers: 190.62
Cuda: 2.3
OS: XP-Pro_64 SP2
Memory: 8181.18 MB
Boinc 6.10.7

I hope the above setup will Help others.


Again, Thanks for your Help

Thank you for your help ..... Paul D. Buck & GDF

You're welcome ... :)

Good news is what we live for ...

Keep an eye on it, sometimes there are other things going on. Some cards start down-clocking or going into power saving modes ... so there could still be issues.

But, slow changes is usually the best thing.

If you watch you can see I usually will make a comment when I am about to try a new version that I think has sufficient changes to make it worth while to risk ... then a week or so later I will say that it may be worth the risk if you have certain known problems to upgrade ... and it is usually a month before I will start to say that this is a stable version ...

Slow changes ... :)

And upgrading for the sake of upgrading is rarely worth the risk...
