Period (in milliseconds) to check for scene updates 2000 Change how fast the view randomly moves around 1 Make particles bigger or smaller 250 Make particles bigger or smaller when using uglier particles 40 These are values that I have right now. I have a hunch that apps instability started when I changed these values. Thanks
2) Message boards : Number crunching : 5970 validate errors (20% ~30% WU's) (Message 56707) Posted 3 Jan 2013 by popo666 Post: New info: sometimes I get message from system, that GPU driver stopped responding and was successfully recovered. In that case, each running milkyway WU fails imediately, or computation will continue indefinetley, until I recognize it and manually abort WUs. After this accident, validation errors or computation errors will ocure higher rate than before the accident. Strange is, that to fix this issue I dont have to reboot PC, I just have to wake on monitor (move mouse, hit keyboard). I have disabled monitor timeout in windows AND in EPU control panel provided by Asus (motherboard ventor). TJ: 92+ Celsius seems to me like pretty high temperature. Mine 5970 runs at 82 to 85 Celsius max (ambient temp is arount 20 this time of a year) EDIT: Now I have found, that something enablet display timeout in windows power manager to 20 minutes. I have disabled it and will monitor it if its still disabled.
3) Message boards : Number crunching : 5970 validate errors (20% ~30% WU's) (Message 56660) Posted 28 Dec 2012 by popo666 Post: But nothing mentioned here explains, why just one of mine cards produces invalid results, and just under this project. Can someone tell us, how is validity measured? I know that there is some difference in output numbers for each run, but how big this difference has to be, to mark WU as invalid? Thanks. TJ: I'm thinking, that memmory on our cards is suffering from extra heat and some errors occure in it. Because I have just stock cooler, I'm not willing to rise up voltage. Nor can I underclock memmory, in catalyst control center 1000 MHz is minimum allowed and also, this is stock for 5790. Another to TJ: How many PCIe slots does your MoBo have? In what number (from top) is your 5870 that produces errors? I may try to swap 5870 and 5970 to see, if its some PCIe related error.

And no I do not think you can separate the internal cards from each other. But one thing you might try is downgrading your drive a notch or two, sometimes the latest and greatest is not the ideal one for crunching. As for turning OFF your a/v I would not do that, but I WOULD exclude the Boinc directories from scanning though. IF Boinc gets a REAL virus, as opposed to a false positive, it should try to infect the rest of your system and get caught then. IF it is a false positive, who cares and IF if it a REAL virus but never leaves the Boinc directories who cares then either! That just means the projects have to deal with it and if they don't have protection from the thousands of users that are sending files back and forth to them, shame on them! I do not use Steam but my Flash crashes too and the units still crunch and finish up just fine, so I am not sure that is an issue for Boinc. Are you overclocking by chance? How about the gpu, are you oc'ing it? - Older drivers allowed users with 4970 cards to turn off internal crossfire, I hoped that it can still be done. - Ill downgrade drivers as a last option, because I heared that no newer driver will be made for HD5xxx cards, just bugfixes for this one. As there was no bugfix for this driver, I assume, that its pretty stable. Dont forget that 5870 in this system chrunches without problems and other projects does not suffer with validity issue (SETI, WCG). - card is not overclocked, after UNDERclocking the card the error rate of all WUs didnt change, so I dont find temperatures, or HW stability as an issue here. I'm now on stock clocks. - Mine motherboard has some energy control unit (EPU). I had it on auto mode, now turned it to HIGH PERFORMANCE mode, hopefully this will help. Has anyone experienced any problems with EPU?
5) Message boards : Number crunching : 5970 validate errors (20% ~30% WU's) (Message 56618) Posted 23 Dec 2012 by popo666 Post: 1: No games or other SW is turned on while errors occure. Errors are produced even after clean boot of system. Antivirus soft is turned off, I'll turn autostart of Steam just to be sure. Steam uses flash plugin as long as I know and it already crashed few times. In my system there is integrated GPU in CPU, display is connected directly to it, so AMD cards have no cable attachet to them and should not be used by system for other than BOINC. 2: As long as I know, 5970 has internal crossfire. Is there a way how to disable it? 3: What are acceptable temperatures for 5970? to TJ: strange is, that mine 5870 works without errors, just 5970 produces them.
6) Message boards : Number crunching : 5970 validate errors (20% ~30% WU's) (Message 56614) Posted 22 Dec 2012 by popo666 Post: I have obtained EAH5970 and started crunching this project on that card. Problem is, that on some days more than 30% WUs results in validation error. Card is not overclocked, after underclocking the card made aproximately same amount of invalid ressults. I have most up to date drivers. No anonymous platform. EAH5870 in same machine works flawlessly. I tryed some other projects too, World Comunity Grid, SETI@Home, and just two from 900 WUs ended with validity error (that is less than 0,2%). Any sugestions?
7) Message boards : News : sending out some more workunits (Message 47454) Posted 10 Apr 2011 by popo666 Post: Milkyway@home 0.57 ATI app is behaving like this on my server (2,7ghz dualcore AMD, ATI 5870 and GTX260) : sometimes it runs smoothly, sometimes it does not use my 5870 at all (progress is 1% after 5 minutes, GPU load is 0%), after reboot same WU crounches well. Second thing is finishing of the task. When progress is 100%, some WU stay in this state for more than 30 seconds. No errors so far, all WU are validated, with no errors and I have 16 task cached.
8) Message boards : News : bypassing server set cache limits (Message 46099) Posted 9 Feb 2011 by popo666 Post: I agree that this project requres a new population every few hours, but there is a great gap betweet GPUs and I have 5870 that runs out of work in less than 18 minutes (if no work is sent). I dont want to participate in math projects, so my card is idle in last month for 70% of time. Some projects have ability to chose a longer WUs, but I didnt find this feature in settings What can I do to reduce this idle time of my card? I cant find any suggestion here on forums.
9) Message boards : Number crunching : GPU disabled when I connect to machine remotely (Message 42062) Posted 12 Sep 2010 by popo666 Post: Hi all I have a little problem. Runing Windows 7 32bit machine with 280GTX. When I connect remotely to the machine via mstsc (microsoft remote desktop), VGA becomes disabled, becomes disabled and CUDA crounching stops. If I'm away from home for a week, this is a problem. Under device manager, card is still active, not disabled. Any idea what to do?
