My last five WUs were SANTIs. Four gave errors. I wasted 25 hours of electricity.

Until someone fixes this, I will now abort immediately any SANTI I get. Sorry...

I can "only" see 3 failed WUs in your account, with 1 of them also failing for others.

Could be as simple as a machine needing a cold-boot.

I have had 5 SANTI's fail in the last couple of day's. 8 in total if I go back 4-5 day's.
I have shut down the computer completely and restared twice now.
Yes, 1 or 2 have completed but the fail rate is unacceptable.
I have changed nothing regarding system setup so it's starting to look like these SANTI's are faulty ??...and yes it is a waste of electricity...

Hm i didnt wanted to write my single failure down about santi, but as i see here in this thread....on a 1GB 560TI (384 cores) i had a santi long fail too i immediate switched it back to short because after POEM GPU Stopped i need every credit i can get to "hold" the OverallRAC. But i have still 310.70 drivers on it.

I had to set my third computer so far to No New Work because of the SANTI work units causing BSODs. So far the systems I have had them on Windows 7 premium and professional x64. The cards were GT430, 650Ti, and 660Ti. From what I could see, it has been caused after the drivers crashing many times in a very short period of time. These devices have run GPUGrid for a while and still run solid on other GPU projects. The BSODs only happen when running GPU Grid SANTI work.

Drivers version on these machines:

Another SANTI just wasted five hours of electric; here.

"The simulation has become unstable. Terminating to avoid lock-up".

Different WU types need different GPU (electrical) power (at a given GPU frequency). This kind of error could be caused when the processing of the WU tricks the GPU's power scheme, and it gives slightly lower voltage for the GPU than it needs (or slightly higher frequency it can run at). It can be fixed either lowering the GPU frequency, or raising the voltage. Sometimes it's not easy to do on a Kepler (i.e. MSI Afterburner). I had to use the Kepler BIOS tweaker utility to permanently fix this kind of errors on my overclocked ASUS GTX 670DC2OC. This is a very useful tool. If you put nvflash to it's working directory, it can directly flash the modified BIOS to the card.

Another Santi errored out today. That's five in five days out of a total of 10.

That's 36 hours of wasted electricity.

No comment here from the scientist...

Just had the same thing happen with a SANTI_bax2 WU on one machine. It BSODed everytime BOINC started the SANTI WU. Even caused disk corruption once. 650ti GPU. If I suspended the WU the machine ran fine. Finally aborted the WU and DLed another SANTI_bax2 which is so far running OK. Before that WU the box in question had run for a VERY long time without a single crash. I've run 18 other SANTI_bax2 WUs without an issue. Wonder if perhaps some WUs got released with bad parameters? Maybe a corrupted DL?

Also as I mentioned the error rate is around 6%

I noticed that most of my failed WU's occured on 1 of my 2 cards. Upon investigation I noticed that the card with the WU failures was running at a slightly lower voltage.Rather than mess with the voltage ( up till now both cards have worked well) I lowered the GPU clocks by 10mhz and so far all WU's have completed successfully..... finger's crossed...

Also as I mentioned the error rate is around 6%

For me, right now, it's 50%...

Impossible for me to find out if there's a relation, but I had 98% processor usage. Changued to 100% and got 2 Santi Errors...
May be just luck?? Or the continuos interruptions I had before made these units go better. I think someone should have a look... I simple test I see would be put forced interruptions and send the same units to the same computer.
Maybe just hazarous, or Santiago doesn't get on well with the GPUs. :p

I lowered the GPU clocks by 10mhz and so far all WU's have completed successfully..... finger's crossed...

Please try the same, Tomba. Lower the clock speed of the offending GPU by 13 or 26 MHz and see if it helps too.

MrS

If you check my posts you can see that I am nagging about the Santi WU's LR and SR since summer. All problems on the GTX660.
I got 770 in Augusts and that worked error free for 33 days consecutive. I built a new system to accommodate a GTX780Ti and put two 660's in the other system. That give error after 2 days running both Santi's. I replaced (on advise here) the 600Watt PSU to a 750Watt PUS and since then it is crunching error free for 4 days in a row.
It could be that Santi's and 660's don't work well together on a weak system (older MOBO, older BIOS) or a PSU with less overhead. I have no proof of this, but it is what I am seeing now.

@Tomba. If you have your new system ready with two 660's in and they run the Santi's smooth, then that would be little proof as you then have the same CPU and MOBO as I have my two 660's in running. Exciting.

Dear MrS,

You are recommending I downgrade the performance of my "offending" GPU to accommodate Santi WUs.

In the past month my "offending" GPU has processed 28 Nathans without one single error, vs. 31 Santis, seven of which stopped with errors that cost me 45 hours of wasted, expensive electricity.

Why do you want me to penalize Natans, that give 10% more credit than Santis?

Why don't you fix the Santi problem??

Some work units are easy, some are hard. You have to live with it; I actually like the harder ones better, since they exercise my card more and may do more challenging science(?). At any rate, I have just "downgraded" a GTX 660 to a base clock of 967 MHz (with corresponding reductions in the boost and maximum clocks), but also boosted the voltage on the core up from 1.162 volts to 1.175 volts to get it stable, and increased the upper power limit to 115% max. If that is what needs to be done, OK with me; I don't expect the scientists to design their experiments for the weakest cards out there.

I don't expect the scientists to design their experiments for the weakest cards out there.

Yes, it would be convenient if they had a "worst case" work unit we could run, to see if our cards are stable on it. Then we could adjust the cards as necessary, or just accept the error rate for whatever it is. But I doubt that even the scientists know what the worst case really is, or what they will need in the future.

Many of the cards are way overclocked for the gamers, and just inherently have a higher error rate. But the ones they do complete successfully are valuable for the science. Only the scientists know the statistics for how many errors they are getting, and they have to decide whether it is good enough. You are right that they don't get any work done if everyone leaves the project, so they have to set a happy medium that everyone can live with (or at least enough people to get the work done).

I am not a gamer myself, but perhaps they could set some warnings out that would alert new users to the possibility of problems. Then at least it wouldn't come as so much of a surprise when they inevitably happen.

You can change it back when the problematic Santi WUs are cleared from the queue.

I'm not caring about the points but rather stability of the systems involved. Until now, I didn't have to worry about running GPUGrid work units. I now have three boxes I have had to pull due to these work units. It isn't just 6xx series cards as I have pointed out. It also effects the GT430's as well. I run all of my cards at stock speeds and don't over clock my CPU's either.

I have more than enough over head on my Power Supplies. I don't believe someones work around by modifying each machine is a justifiable argument for everyone else to have to go tweak their systems just to run SANTI.

This is something that should be able to be fixed within the application.

Since this is a known error and it is happening to multiple people with different cards, it certainly should be looked at further.

Yep! And pigs should have wings so they can fly themselves to the slaughterhouse so I can stay at home and harvest money off my money tree.

Reading all this thread, I'm not sure if there's a problem with OC cards or complex units. I will stop my computer and read carefully the weekend to understand what's going on.
But I would like to point something.
Whats wrong if you want to be a "passive" cruncher? and you don't want to worry about Linux, scripts or whatever. what's wrong with this?

I think you can't expect to have every user on this proyect to be a geek on hardware.
Of course people with best machines are very familiar with this Project, but there's another profile of BOINC cruncher. People with multiple Project don't want to get in profound with technical specs. I think an easy solution should be proposed for these people.

Maybe "geeks" should help providing an script or whatever somepeople sugested. IMO

Dagorath, glad you are still trying to make a few suggestions and stick to that very narrow mindset. My reasoning for the app change rather than making users make tweaks locally for one sub project is more focused towards those machines that don't have easy access and can't be tweaked remotely on a day to day basis. As far as giving people the option to choose between SANTI and NATHAN adding more problems, that is yet to be seen. Until then, it is only opinion which really isn't worth arguing. In this case if the option was a choice, GPUGrid would still have 4 more GPU's from me crunching away. I'm sure others who are having difficulty would do the same. I have no idea the true numbers of people experiencing problems because not everyone posts in the forums. I don't even know if the techs here look at the work units I have aborted that were causing the BSOD's because they didn't get to "error out" and therefore would not show up that way. Instead it would show up as a user abort and someone else who didn't have BSOD issues could finish it. I'm not saying my cards might not be overclocked by the manufacturer. So, I can assure you that "point" was not missed. I just didn't address it in my above statement. I have made my choice in regards to tweaking my cards and have expressed my opinions (which is what they are regardless if you like them) on how I feel about the issue at hand. Please choose to ignore them if you don't like my approach.

To finish and not making it too long. Just the feeling of something being done or an explanation why there's nothing can be done could be fine, at least for me.

Have been crunching GPUGrid WU again since about a week ago with two machines, three since yesterday, and had no problems with SANTI, NATHAN, NOELIA or SDOERR. I had a BSOD today while crunching a Nathan WU. I thought it was a software problem and installed the new drivers (331.82), which didn´t solve the problem. After reading these posts decided to lower the core clock and so far so good.
Thanks for the suggestion

Wow they have really harder requirements on that SANTI Batch it seems. I run one successfully with 50mV overvoltage on the 560ti 384core. Until now, all cards run with +25mV and computed successfully with this setting, Santis too. But only this card needs more. But +50mV needs serious cooling.. im nearly at full fanspeed and over 80degress with open case and no extra heating in the flat.

After 17 days a Santi resulted in one 660 to down clock. And only 2 errors in 19 days. But today my rig with to 660's was booted when I found it. After logging in it booted immediately when BOINC started a few times, so I went to Windows in safe mode where I have some more time to abort the task. As I didn't know which one, I aborted both. Its now happily crunching again.

Just now I found my rig with two 660's frozen. No Idea when it happened, even ctrl-alt-del didn't work. After booting immediately message that the graphics drives has crashed and recovered, three times in a row and then it booted itself again. After three attempts I got BOINC to stop. I am now installing the latest beta driver but that should not be necessary and it ran for more then a month with the 331.82 driver.

I have not a lot of joy with the 660 since I bought two of them in summer.
I don't like these Santi's.

Again I found my rig with two 660's frozen.
After 5 boots I managed to get rid of all the Santi's and switch over to LR only.

It is or an AMD CPU has problems with Santi or GPU's lower tan 7XX have problems with Santi's or a combination of the two has problems with Santi's.
I guess none of the above as there a re many AMD rigs and many more rigs with 660 that does there terrible Santi's. But my RAC is rapidly falling this way.

Edit: another Santi crash, so will become 7 boots eventually. I start to hate these Santi's!

Edit 2: Yes I got two Nathan's on the 660's, so I can go sleep this night and not watch my system continuously.

Greetings from TJ

TJ, you should lower the GPU frequency of those 660s, or increase the GPU voltage by 12mV.

Boost the voltage and produce more heat or get crunching on Linux. Take a look at my results. I have errors but 99% of those are tasks I aborted because I played with stuff and ended up with too many tasks in my cache or other reasons. I have two 670 and one 660Ti on Linux and they almost never crash SANTI tasks. I'm running the stock clock speeds and if I keep the temps below 70C the clock boost thing kicks in regularly. They hardly ever crash on any task and if they do the OS doesn't hang, BOINC continues running, another GPUgrid task downloads and starts and life carries on.

Hi Guys,

Good advise. I lowered the clocks per Zoltans advise and will see what happens.
If not stable I will increase the voltage little.
Problem is that the rig was stable for 17 days continuously, that is wondering me.

I let them run at factory settings, at first months ago. They are both form EVGA. Their maximal fan speed is 74%.

Greetings from TJ

You can start a snowball effect with system freezes and BSOD's if you don't run checkdisk after getting those errors, too many orphaned files or wrong time stamps and such just causes more and more problems. If you don't do that, the errors your getting now could be related to it.

Your cracking me up TJ, you think your BSOD's and freezes are because you have an AMD system? I think the drought were having in California is because of the Intel CPU in my laptop (gotta put on my tin foil hat).

No BSOD but again a frozen system. This time by a Noelia on my 660's rig. I did manage to get the clocks down with Pricison X from EVGA, but after a while they boost automatically again. Trying to do it with MSI Afterburner, shows only one card, there is nowhere I click that I can see the settings of my second card.
Well from August these 660's are trouble some to me, so I will buy a second 780Ti as it, even in Windows7, does the same as two 660's is less time to replace the 660's.

Just had to move my 560ti onto the short runs

Even got the Dyson out expecting a GPU full of fluff but no it's the Work Unit's

Just 2 successful long runs since 24th Dec


There's a problem with the current batch. I'll just have to be patient.

Maybe this time next week

Your clocks are too high. Try 1644Mhz for the processor & 2004Mhz for the memory.

'GPUgrid stresses the parts other projects can't reach'

Probably would be useful if people having a problem with a self overclocked card would return it to stock clocks before reporting problems with WU.

These clocks arent oc on 560ti 384 O.o try +25mV first but it can fail then too anytime. Try to underclock then. But its not a must it works then ;(

It seems every type of task has its own tolerances too, am I right?

You can run NATHAN tasks at high clocks and lower voltage but SANTI tasks need lower clocks and/or higher voltage?
