Hi there.
I have overclocked the shaders on my 9500GT card but I keep getting computing errors. I have now reset my card back to default values but the errors are still occuring. To date I think its up to around 20. Anyone have any ideas how I might fix this. I have tried a reset of the project and a detach but nothing works yet.
Thanks.

Eric

Check the fan and the air path around the card to make sure that it can be cooled. Use one of the monitroing tools to get the card temps ...

ONe other thing to try is to run a few SaH tasks to see if they complete (though you will have to wait for them to validate and be paired up with a wingman) ...

These are the first things that come to my mind ... weak as it is ...

Thanks for the info. I found the fans and air vents were ok. I then did a complete re install of my operating system as it was unstable. Re did all the drivers and re did Bionc. All is fine now.
Once again thanks for repling.

Eric,

It is what we are here for ... I help you ... others are trying to help me with my issues ... all to the betterment of the universe ... :)

One of the lessons I learned when I was writing documentation for BOINC is none of us knows it all ... or can do it all ... there is always more to learn ...

Just because I can't get Linux beat into submission at the moment does not make me an idiot, nor does your difficulties ... I am just glad that you found the problem. *MY* experience with windows is that I would have to do a clean install about every 6 months to keep the systems running stably. When I only run BOINC and don't use the system for much of anything else it seems to last longer ... YMMV ...

Kodak, what are you trying to say? Do you have "Continual computing errors", as the thread title implies? I can only see one error for the host you linked to. And I see his 9600GSO is overclocked quite a bit, so an error every nwo and then might well be within expectations.

I think he's talking about his other computer, which is throwing a ton of errors. Here's one: http://www.gpugrid.net/result.php?resultid=569330

Want to find one of the largest known primes? Try PrimeGrid. Or help cure disease at WCG.

Kodak, your 9600GSO is overclocked by ~350 MHz. If you run such a high OC and at some point it starts to fail the first thing you should try is to lower the OC and see if it helps.

i about http://www.gpugrid.net/show_host_detail.php?hostid=31714
in it only one overclocked by shaders from 13xx to 1734
second is asus top shaders =1674 OC to 1734
today low OC to 1674 same errors(((
cards not hot ~ 56-60 C
--info
1s WU run's ok ( no more WU) -> update
+3 WU
start 2nd run->ok BUT
start's 3rd wu run-> fail OND start's 4s wu run-> fail !!!
and return run 2nd wu and ok
Whay start's 3 and 4 (deadline is almost same!!!) ??????

and ?
what better use 2 GPU in one PC or 1gpu+pc +1gpu+pc ?????

what better use 2 GPU in one PC or 1gpu+pc +1gpu+pc ?????

That's hard to say, but right now, I'd go with 1+1 and 1+1. GPU computing is relatively new to BOINC, and the BOINC scheduling software is far from perfect. It seems to have issues with propper scheduling when there's more than one GPU (especially when there's different GPUs in the same computer).

Once the scheduling issues are eventually resolved, things might change. But for right now, I'd put each GPU in a separate computer. It's also easier on the power supplies and the cooling (summer is coming, after all.)

1s WU run's ok ( no more WU) -> update
+3 WU
start 2nd run->ok BUT
start's 3rd wu run-> fail OND start's 4s wu run-> fail !!!

IT is only 2xGPU (

You started at a reported shader clock of ~1730 MHz, then you went to ~1715 MHz and still get errors and now you're running 1693 and 1700 MHz and still get errors.

Do you know that the clock speed on current nVidia GPUs is nto continous (i.e. 1 MHz steps), but discrete with much larger steps? For the shader the step size is about 54 MHz (can't remember the exact value) and changes smaller than this likely don't change anything. Most tools (also the GPU-Grid task output) only report the requested clock speed, but not the real one.

So back off to 1600 MHz shader or so and see if it helps. Also don't forget the chip and memory clocks.. if they're also overclocked you should reduce them as well. It could also be a too tight OC on the CPU and/or memory.

OC only shader \ chip and memory - is default

will be fine work
9800GTX+ VS 250GTS ? (it is only diff name , shader - 128 )

Hi. I have an overclocked 9800GTX which was running very smoothly. Until 3/4 days ago, when I behgan to obtain a long list of "computation error". Nothing has changed when that problem has begun (for example, I haven't installed any new driver).
This is a typical error:
<core_client_version>6.6.20</core_client_version>

Can you help me?
Thank you in advance.

You are running in device emulation, no card is being used:

# Using CUDA device 0
# Device 0: "Device Emulation (CPU)"

Your last success result 566035 shows right config:

# Using CUDA device 0
# Device 0: "GeForce 9800 GTX/9800 GTX+"

Re-install?

I have to reinstall the video drivers, or BOINC? Or both?
Thank for your answer.

9800GTX+ VS 250GTS ? (it is only diff name , shader - 128 )

What are you trying to say?

9800GTX+ and GTS250 are the same speed, but the GTS250 can have a lower power consumption.

Thank for your answer.

I'd try BOINC first, try with version 6.5.0 though...
Although folks here in the forum may give you better idea on what client version is "safer".
