I've been using Mailwasher (because it has a nifty Bounce option) to filter,

Bouncing emails should be banned. All it does is increase network traffic- it doesn't have any effect on the amount of spam that is sent.

I know the activation emails go through fast. As soon as I clicked submit, Outlook chimed at me. It was nearly instantaneous.

I trigger each bounce manually. I only bogus-bounce 4 or 5 messages each week, and my name seems to fall off the list and not get propagated to more lists. I'm a convert. Spam near zero. Very good for network traffic.

If you mean to say some software bounces all possible spam, yes, that would be bad. That should be banned.

Sorry about the tangent.

I have problem with app V6! you can read all on lunatics.
My computer was very slow, and even in 2 hours the app was unable to process the WU.
You have to install a script to monitor the progress. everything explains here.

I'm back to app V5b!

App Raistmer's_opt_package_V6 is very capable of processing mid and high AR. In VLAR I had problems. I'm gona leave this V6 app. Even the server don't send WU's with VLAR, for now! Good for me!!

A teammate use BOINC V6.6.0 and crunch simultanously MB/AP on CPU and MB on GPU. (stock apps)

He made something 'wrong' or is this possible in BOINC V6.6.0?

It would be possible also with app_info.xml ?

By using different preferences I am at present running MB 6.03 AP 5.00 and MB 6.08 (cuda) over at beta.

Look under My preferences on your account page

You have a choice of four default Home School and Work .

Choose MB enhanced, AP Astropulse Other work and Use GPU

BOINC 6.6.0

Same applies over here using different HOME set to MB AP NO NO
and WORK set to MB AP NO YES

Or you can write your own.

Hi.

I think I remember reading that you had 2 nvidia cards. I could be wrong.
Just wondering if you're running your 9800 as secondary display.
If you were, the results from that configuration would be quite useful in
tracking down vlar wu errors, since a a secondary display card configuration
for the Cuda Gpu has fewer limitations on "GPU task instance duration errors" and
would narrow the the search down to the real cause of vlar errors more quickly.
I do believe the problem is in errant algorithmic conversion to cuda code.


How do I know when the "GPU task instance duration errors" kicks in? I searched thru the cuda forum at nvidia but did not get any hits on "task duration" or "task instance". I did get some hits on google when I substituted cpu for gpu but not in the context of this post.

Anyway, I would be interested in knowing more about this. Also, my mombo has built in intel graphics I am not useing, but I assume I could use it as my primary display and free up the gtx280 if that is useful and IF I had a WU that produce the error.
Yesterday, I had a "6.08 seti beta cuda" wu fail, generating an nvidia fault, but when I ran it in standalone mode it ran fine. Let me know if there is something I can do.

Not yet. As far as I know, the present BOINC versions still have a bug where when they detect that the primary video card is not CUDA capable, it'll stop trying to find any next one. This ought to be fixed in a future version, although I can't tell you in which one that'll be. You'll have to test that. (Seeing you're running 6.6.0, it may have the fix in it already)

I forwarded that one to the developers. Thanks.
Any more of those around?

I attempted to boot using the builtin intel graphics but this mombo (D965WH with latest bios) seems to allow either PCIe or Internal but not both. Only one showed up in the device manager under display ie: the one selected in the bios. However, a tyan s2892d mombo at work shows both ATI internal graphics and the 9800gtx and it is also running 6.6.0 and vista 64 so I will try that one the next chance I get. BTW, the gtx280 would not fit in the tyan on account of a capacitor blocking the seating. Tech support (xfxforce) advised against using a dremmel to remove part of the plastic housing on the gtx280 board that was causing the problem.

Hi there;

In great sadness I have to report that I uninstalled the latest Boinc Version
off my PC.. It was overheating my GPU and causing my computer to shut down and restart at random. I uninstall boinc no more restarts. Also to try something else to see if my theory may be correct. I did a "Stress Test" to test my system. The program was available through the NVidia control panel. During the stress test program test the GPU as well as the CPU. During the test my PC shut down and restarted. SO sadly i took off the program after running it 3 years straight. Any recommendations or thoughts on this.

My 8800GT (1gb) has a huge plastic housing cover on it, and it was also in the way of a capacitor. Fortunately for me, the plastic housing is held on by 4 screws, so I just took the screws out and the housing came off just fine. No "warranty void" stickers anywhere on it, and now it plays nice with capacitors.

Just a thought.

I have been reading allot about errors with running cuda.... I found that nvidia simply does not provide enough support with their drivers to increase fan speeds when under these extreme loads. As a matter of fact my fan will not go above 10%, my second gpu fan will not go above 1%. After a while both my cards started to error out every task, until I restarted the pc.... I searched everywhere online to find an app that will control the gpu fan speed as ntune does not do this for both gpu's.... it will only correctly change my primary gpu fan speed..... Nvidia now supports 2 non sli cards, one to run graphics and the other to run physx for gaming purposes.
So for anyone needing help, open that nvidia control panel and change your single gpu fan speed to 50% at a minimum, you can set a profile to load when windows starts.
Anyone using multiple gpu's as I am, download Riva Tuner, it was able to change both fan speeds and seems stable on my rig, im running both gpu's now at a temp of 143 F for my 8800gts g92 and 154 F for my 8600gtoc. Both fans have been set to run at 75%.

My machines have Intel graphics built-in. I simply put the nvidia card in (mine is a 9800GT) and it took over the video. I didn't change any BIOS settings or jumpers. It uses the first DVI connector. After that it comes up in standard (640x480) VGA mode until you install the drivers, after which you can select the monitor resolution, etc. I updated the driver to 180.48, as the CD had older ones. Plugging the monitor into the mobo's video results in no video signal.

I could be mistaken, but I think only the CPU temps are capable of shuttdown a system. What were your temps, both CPU and GPU? What does speedfan show for idle and full load?

full load should look like this


idle should be about 15c less for all cpu's, something like this:


Make sure the HSF on your CPU is down tight. I added a fan to the case side immediately above the nvidia board. But I was lucky there were air vents there and I didnt have to cut anything. I would not recommend anything like this

@ wandering willie

O.K., but this is only a temporarily solution.
And only with user activity.. not automatically..

I would like to have a BOINC-client which can manage simultanously MB/AP on CPU and MB (soon AP also) on GPU.
They work on this and I thought BOINC V6.6.0 could do this.
