I have 4 LR from Santi erroring in a row, after 32000, 34000 and 40600 seconds.
But there are more errors from Santi LR, most wingman have errors too and some already more then 4. If I compare this with the my error rate from Noelia's then are the Noelia's absolutely not bad. I would like Noelia's WU now, as after two days of continuous crunching during a heatwave none LR have finished normal.
This is no fun at all.

Hello: I see your GTX770 performance is very low, it took more than twice mine.

The difference from Windows to Linux is not warranted, at most 5% + - looking at his PC also see that the CPU performance is low, possibly penalized as fast GPU.

You are correct, looking at my BoincTasks history log for all my machines combined, there have been quite a few (at least 27) SANTI errored in the past few days. Except all of my errored units are the short SANTI runs. Not just a single machine, it happened on all machines and windows xp as well as windows 7.

So it's the short ones that are the problem? Because I'm not experiencing any issues wight the long runs.

Dont have issues too on both short and long santis

My last LR that finished is from 21 July. I see that all LR from Santi and Nathan only use around 25% of memory, while that was 48% a few weeks ago.

Looking close at the systems I see that after a Santi SR finished without error or a Santi SR errored out, that the GPU clock is down clocked and I need to reboot to get the clock running at around 1024MHz again. That's no problem if I am with the PC's but at home I cannot boot my rigs at work.
This explains why some of my SR run so long.

As I have more errors than valid results and the heatwave is now official in the Netherlands and continuing I will power some rigs down for the time being.

To provide some counterpoint, my machines have completed 18 (and 3 more nearing completion) SANTI long WUs with no failures, no problems at all. This includes GTX 670, GTX 560, GTX 650 Ti and even GTX 460/768mb GPUs. The ones that are showstoppers here are the NOELIA RUN WUs which won't RUN properly on anything but the GTX 670.

I've crunched a couple of that NOELIAs on my GTX480 properly.
I'm quite sure, that the GTX 660 Ti is capable of crunching these workunits, but it needs an older driver (v307.90~v314.22) to do that.

Strange how different hardware/OS systems handle things. My 660Ti crunches NOELIIA and NATHAN tasks without any problems with the 320:18 drivers and XP but it chokes on the SANTI_RAP74 tasks. Maybe I should drop down to the 314:22 driver and see if the SANTI_RAP74 tasks play nicer.

I have again 3 Santi errors in a row on my GTX660 with 314.22 drivers after 60-70% of the WU finished. I have set this host to SR´s in the hope to finish WU´s without error. All the errors are not helping science.

Have you tried the 310.90 drivers? MY GTX 670, GTX 560, GTX 650 Ti and GTX 460/768mb GPUs are now at 44 SANTI_RAP74 WUs completed with no errors. I'm using 310.90 drivers (like your machine, running Win7-64).

Looking at your GTX 660:

http://www.gpugrid.net/results.php?hostid=153284&offset=0&show_names=1&state=0&appid=

It looks like a lot of NATHANs and NOELIAs are erroring too. If it's not OCed try slowing it down below stock specs or move it to a known good machine. If it still errors, RMA it.

The specs on the box are not always good for all tasks from GPUGrid. None of my cards would run @ boxedspecs errorfree ^^ Since Fermi&Kepler changes are needed sometimes. 2xx and lower run all at original specs longer time ago ^^

Looks like switching to the 310.90 drivers may have solved my error issue with the SANTI_RAP74 WUs. Just completed 1 with no errors. Have 1 now running and 1 more in cache. Fingers crossed.

I went back to 310.90 drivers to for the 660, but still errors on the SR. One LR Santi did finish same did Nathan and Noelia WU.

My AMD PC with a 770 and driver 320.49 had nil errors yet and did all types of tasks.
It looks to me that the 660 and Santi WU's need a special set up. The PC is now running a Santi_bax1 and I see the Kernel times slightly rising. When a Noelia ran this morning, the kernel times where very flat, almost not visible.

TJ, have you ever tried installing the drivers without the stuff you don't need; sound, 3D vision, updater?

There is definitely something going on. :)
My main cruncher restarted two times while crunching this 23x15-SANTI_RAP74wt-7-34-RND0953_0.
Later on, this 13x10-SANTI_RAP74wt-8-34-RND8572_0 run into an error, the subsequent 84-NOELIA_005p_express-2-3-RND1913_0 also run into an error (on 3 other host too), and the following 9x0-SANTI_RAP74wt-6-34-RND5647_1 had a stuck progress indicator, so I've aborted it, but the following WU showed the same symptom, so I've restarted the host (the WU finished fine then).

My other host (with a new CPU and MB) had similar computation errors and two WTF-type SANTI LR:

47x9-SANTI_RAP74wt-8-34-RND9533_0

One LR Santi errored after 21000 seconds, but one finished okay. But I had a system crash overnight as well. The course seems to be a Noelia. After a restart I got a Santi SR and that failed after 1419 seconds. Thankfully I have a Noelia LR now! However I had a Noelia failed and caused the nVidia driver to crash, they do that within seconds.
If I am at my rigs and I see a Santi I will abort it for the time being. They error way to many. I don't care about the credits, but for the energy though. The GPU could do another project than, to help science.

MY GTX 670, GTX 560, GTX 650 Ti and GTX 460/768mb GPUs are now at 84 SANTI_RAP74 WUs completed with with only 1 WU that errored after a bit over an hour. Again, I'm using 310.90 drivers in Win7-64. The only WUs that are a problem here are the NOELIA_RUN and the new 290... NOELIAs, but that's because they need > 1GB memory or they slow to a crawl. Personally I wish all the WUs were SANTIs.

My own recent experience is that Santis are fine if you don't overclock. But they are very particular. I have had to recently reduce the clocks on my GTX 660s from 993 MHz (a factory overclock of less than 1 percent) to 980 MHz, the Nvidia specified rate. I have also tweaked up the core voltage a small amount for some additional overhead. That had not been necessary on any of the other longs, but with the Santis they work fine, until you get a hard one, and then they fail.

That is OK; I want the science to use my cards to the maximum extent, and don't want them to slow down the science just to accommodate some card's overclock, but we need to be aware of it. And I have not found that the driver version makes a difference; it may just be a slight difference in the difficulties of the work units themselves that matter. You can go for weeks at a time with no problems, and then they lower the boom on you.

Hi, Beyond:

I too wish all WUs behaved as well as the SANTIs!! :)

I don't want Santi's any more again 4 fail in a row LR and SR on the 660. I have also 310.19 drivers, in fact I have tried all drivers from 3xx.xx until latest beta, and no OC. With Noelia and Nathan with every driver good results.
Thankfully my 660 has a Noelia now for the next 14 hours. So I can safely leave the PC alone.
My AMD with GTX770 and the latest official driver, does all WU, including Santi okay. So I will only buy 690 and higher cards. They are more expensive, but 30 or more errors after 60% running costs a lot of energy that was complete spoiled.

TJ, the SANTIs run better on low end cards than any other WUs. They even run on my GTX 460/768MB. There's something wrong either with your system setup or your GTX 660. Looking at your computer it reports:

NVIDIA GeForce GTX 660 (2048MB) driver: 311.6

The 311.6 driver is bad. When I tested it I had many errors. Returned to 310.90 and the errors disappeared. I think you need to use driver sweeper to totally remove the traces of all the drivers you've tried. Then install 310.90 and see what happens. If you swap the 660 into a known good system and it still fails, return it or send it to the manufacturer for repair.

Your right Beyond, if I check BOINC first page I see indeed 311.6 however I am absolutely sure I downloaded and installed 310.90. I have even saved the file for just in case, here it is: 310.90-desktop-win8-win7-winvista-64bit-english-whql.

Thanks Jim,

I have it set to not update drivers by MS, but forgot to do that on this particular system. I will let Noelia's finish and then start working on this one.
But I see you have great results on your 660's with 314 drivers, so the 310 are not necessary.

Greetings from TJ

I think the 314 drivers are fine, but it doesn't really matter in my case, since I use a dedicated PC for GPUGrid and don't need the card for display purposes. My only suggestion is if you do upgrade, do a clean uninstall with Driver Sweeper or Driver Fusion; it solves a lot of problems.

Okay, 310.90 drivers are in affect now and system was cleaned with driver sweeper as well. To test it I let it now do SR and no tasks at first on the CPU.
