I had a gtx295 running gpugrid with only the occasional w/u that errors.

Something changed on the 18th and now i get nearly constant errors.
I'm running boinc 6.6.28 with NV 185.85 drivers on Vista HP 64bit.

I cant work out what changed as all automatic updates are turned off and i update everything manually every weekend.Any suggestions after looking through my task history would be much appreciated.

I've just gone back to basics :) un-installed everything nvidia and boinc related. Restarted and cleaned out all traces of nvidia anywhere. Fresh download of 185.85 and fresh download of boinc client.
Reattached to project and now running first 2 W/U. Fingers crossed it was just a bit of corruption somewhere amongst all the files i just replaced.

2 hours into the W/u so far and all looks good.

Will update when they finish.

And there goes the first error

Try going back to the 182.50 driver....

Consciousness: That annoying time between naps......

Experience is a wonderful thing: it enables you to recognize a mistake every time you repeat it.

Since the re-install the errors are only on GPU1 (meaning the second GPU of the 295)
Make sure you've got it configured correctly.

Try going back to the 182.50 driver....

The new drivers for some people made the need for a dummy plug/monitor on the second GPU unnecessary. As long as phyisx is enabled on the second GPU it should detect it. Others have found out they still need the dummy plug/monitor on the card.
The desktop still needs to be extended onto the second GPU.

The new drivers have changed the rules for cuda and has caught a few people off guard. Of course for some the new drivers wouldn't work either.

Bob

I never needed a plug and have never had to extend the desktop onto 2nd GPU.
No drivers or settings changed between it working and it not working.
In the NVIDIA control panel Physx is enabled and the SLI is set to not use multiple gpu mode as it always has been.

The amazing thing is about the drivers is that sometimes they change their mind...

For this next batch of work please dont abort any as you keep aborting the work on card 0 (the first of the 2 in the 295) and we haven't seen if it will error out or not.

I'm sure its not the card.
I see the new host (37017)
currently 4 errors all on the second GPU of the 295.
Nothing yet from the first GPU...
Sounding more like a config issue as there would be errors from the first GPU as well if something was wrong...

Bob

I was thinking the fault might be on the 2nd gpu only hence thats why it is failing.

might try 2 seti w/u and see if both finish.

I have reinstalled everything including vista so everything was clean instal with fresh driver downloads.
Seeing as both gpu's get configured with same setting how can it be a setting issue. If i plug monitor into 2nd gpu instead of first and it still fails it must be card. However if first gpu starts failing tasks then it must be settings. If thats how it works anyway.

ok tasks are still failing on the 2nd gpu regardless of which socket monitor is plugged into.
I'm going to get in touch with vendor of card on tuesday and see what they say as i refuse to overclock something that cost so much in the first place lmao. So at least my warranty is valid still.
EDIT 1
in the meantime im going to run seti enhanced w/u as they dont fail it seems.

Edit 2: Seti enhanced w/u for cuda fly through without a problem on both cores. I'm still going to try for a replacement as it worked then stopped working within a few weeks of use. I might even be inside the ole 28 day mark :)

Did you watch the temperatures on both projects? I suppose they're rather similar at automatic fan control?

MrS

So its quite clear there is something wrong somewhere with the second GPU

A list of things to try

1) plug monitors into both monitor sockets (if you have a second monitor)If not you could try and switch the monitor over while the PC is running (that sometimes tricks it into seeing 2 GPU's)
2) Ensure the desktop is extended onto the second GPU
3) Try disabling PhysX on the first card while enabling it on the second (I think thats possible)
4) Try disabling PhysX on both

5) Run Cuda memory tester (see sticky) on the second GPU

Bob

P.S. If they'll replace it that may/may not work. Its worth a try if they'll go for it.

My temps for running the gtx have never been over 80 while crunching. I have the fan set to 75% which keeps it down around 72 degrees.

I've tried without physx on both cards.
My system doesn't need to be tricked into "seeing 2 gpu's" there are 2 or it couldn't be failing or starting on the second one.

Are you copy and pasting this from elsewhere cos you've said the same thing repeatedly with the same advice time and time again.
Thats not me having a go, i apreciate everyones help its just you keep telling me to do stuff so the second gpu is detected!! thats the same one that must be detected cos its failing work units.

Cuda mem test i have run a couple times but in the readme it states that "In our
testing, we have found that even "problematic" cards may only fail sporadically
(e.g., once every 50,000 test iterations). Like other stress testing tools,
to properly verify stability MemtestG80 should be run for an extended period of
time."

This test throws up no errors when i run it.

As a by note to fixing this maybe it means something who knows but under windows 7 my gtx 295 shows only 1 gpu to boinc no matter how i configure it. 2 monitors plugged in desktops extended and not. Any driver or version all only let boinc see the single gpu.

Just had a fun afternoon anyway playing quickly with W7 :)

Well, I have 3 systems all with 2 or more GPUs running and my error rate is vanishingly small. I mean in almost all cases of error it has turned out to be a bad task or some event where I have caused an issue.

To put it another way, I don't see a problem here ...

how can you not see a problem with the 2nd gpu always erroring w/u Paul. Just because your system is not erroring constantly then all systems are ok? i dont understand that statement.I had the same errors as you to start, the occasional w/u here and there. Then bang, all w/u that 2nd gpu does fail everytime.

Look through my tasks and try to find the last completed w/u on gpu 1.


Popandbob. I salute you for your suggestions i dont mean to be grumpy honest. I can only see the one way of changing sli config. There is no bios option for it and nvidia control panel just has the 2 important ones, SLI and Physx.

I'm nearly back to where i started again with no light at end of tunnel yet but am about to try fresh instal of 64 vista and 182.50 drivers first. Just doing the last updates before i instal boinc again.

OK i'm 2hours 46 minutes into running 2 tasks on it.
723126
723205
Fingers crossed and they both finish so i can sleep easy.

May sound silly but its always failed by now...........

The difference.........

Turned Aero interface off........

I'm just running on the vista basic theme so all the fancy graphic card utilising bumf is off

Could it be that simple for my problem!

SLI is off?

I don't know how W7 handles SLI but there is an internal SLI mode on the 295 cards IIRC, XP Does not do that ... or at least none of my installs have done that (yet) ... then again, I have not had the courage to try Vista or W7 ...

THough I seem to increasingly hit the upper bound in memory which in XP is 2.something G ...

I'm sure its not the card.

Its in a parcel at the post office atm :) will update as it pans out

My problem started very suddenly and nothing i did changed anything in the slightest, drivers, O/S, whole different pc which has none of the problems this card gave me and i still get the same result.

Before this started the GTX295 was running both w/u with just the occasional fail on either core so either something is wrong enough with the gpu to fail w/u which it does in 2 different systems or who knows. the other system i tried it in is running 2 w/u on its own without a problem until i put this card in then it also fails on GPU 1.

I want to state with facts that many WUs processed in any GPU assigned #1 fails, mainly with the newest units.

I begun to have this kind of problems some time ago with Folding. But NO with GpuGrid/SETI. Now I have this problem with GpuGrid too. SETI works fine.

It's Gainward card??? I have ONE GTX 295 from Gainward - one GPU works fine GPUGrid and the other crashed after a few seconds. But its ok for short WUs like SaH. And this not a problem from XP, Vista, Linux or the driver/Boinc version or an unused monitorport, it's the card... Perhaps you can chance it to another...

ok, you are getting the same errors as I was.

I tried mine in 2 computers (with different OS's) and errored on both.

I suspected I had a Bad card but I can run benchmarks with no errors.

I'm just waiting for the argument with customer support when they say they can find nothing wrong. I have a feeling they wont like my answer that its not fit for the purpose i bought it for, namely gpugrid.

Cant be long now till they get back in touch with me, they have had it since Thursday afternoon :(

Check what kind of slots you have your cards plugged into on the motherboard. Not all PCI-E slots are the same. Some run at x16, some at X8, some at X4, etc. I searched hard when shopping for my motherboard to find one that had 3 full speed x16 slots and that was also capable for triple SLI (though you need SLI disabled when running CUDA like GPUgrid). Then, I made sure to use the x16 slots for my cards. Oh, and the x16 slots have to be spaced correctly too since the newer GTX200 series cards are double thick, or they won't fit. Then, of course, the case has to have room for that setup. Check for motherboard BIOS and chipset driver updates as well. Anyway, just a thought.

I'm getting a ton of errors with my gtx 295 as well. =[
I just started gpugrid, and this doesn't make me very happy.
I gave up on using the 2nd gpu and just tried using the first.... and the 1st gpu errors out everything... some within second and some after 20 minutes.
My card is not overclocked, and the temps are in a very good range.

Win7, 185.55, 6.6.31

Annoying to say the least.

The product GX-191-AS on RMA RMA****** has been replaced, this will be sent on a new order with order number *******.

This will be despatched as soon as possible, subject to stock availability.

Well thats that sorted....they tested the card and the 2nd gpu was indeed faulty. It was ok for a bit then the fault showed under load.

Pharg my slots are both PCIe 2.0 16x so that wasn't the problem.

My system ran ok for 2 weeks till the fault showed itself. There where no system/driver changes to blame between working and not working.

Thanks to you all for keeping me sane while i waited for their decision.

:) cant wait to take my emergency EAX800 XT out and slide a 295 back in. It will be a lot quieter believe it or not :)

It's Gainward card??? I have ONE GTX 295 from Gainward - one GPU works fine GPUGrid and the other crashed after a few seconds. But its ok for short WUs like SaH. And this not a problem from XP, Vista, Linux or the driver/Boinc version or an unused monitorport, it's the card... Perhaps you can chance it to another...

Well its here and installed and running its first w/u. New Gainward card.

Faulty one was an Asus GTX295

Hopefully thats my woes sorted out :) will know tomorrow morning :)

Ahhhhhhh lovely 4 tasks done nicely :)
