Happy that helps. You will notice an increase in your host RAC (after tommorrow outage of course) and a better video response in windows.

But be aware, when V7 starts you will probabily need to change to 2 (not sure now) but that is another history we all need to wait until the end of the week to make tests and be sure about that, at least all previous beta tests shows that.

Mike Davis switch to 3 WUs. You win

3 will be best on a 670 as someone else previously said. You can do 5, but it works out fastest for 3 at a time

---

I made manually test. You right. It is not very urgent or very needed. I use 5WUs and lucky. I think it is better for me.

Fred could give you a better hand with his program and results, did you made the test manualy? Or try 4 WU at a time? You could made a table and check the times on each option. Something like this (an example from this host that have a 580):

WU GPU Usage

1 80%
2 92%
3 99%
4 99%
5 99%

So the best number is 3 WU in this host too.

But don´t waste your time too hard on this, with the soon release of V7 all this will change, the number of WU per GPU will reduce to 2 or 3 to be the optimum anyway. Why i don´t know just the the warming on the forum, something related to the way it works.

I think Fred performance test not accuracy
It tell me that 3 WUs best for me and stop (in automatic mode). I try run it for 5 WUs. See pix

That is why I use 5 WUs. Or I did some mistake?

And I need your help again. As you know I make BOING Monitor gadget
http://www.myfavoritegadgets.info/monitors/BOINCMonitor/BOINCMonitor.html

I know sthat S@H run on ATI cards too. I need separate ATI. Can you post me client_state.xml file when ATI task active. And of course, tell me about slon number. My mail is shvaika[at]yandex.ua
Thanks.

Thank you for good help Guys.
I'm lucky now.

Can you post me direct link to Fred performance test?

This message has the link for download. I run either 3 or 4 on my 670. The performance test said they were about the same, and my observations confirm that. I get a 98%+ gpu utilization either way.

As for http://jgopt.org
I must just copy appropriate files to here
C:\ProgramData\BOINC\projects\setiathome.berkeley.edu

Or/and do something else, e.g. change any files like MBCuda.aistub ?

You might just want to wait. The project is probably going to release Version 7 this week, and x41zc will become the new stock application. Timing and the availability of a new Lunatics installer are uncertain. So, if you install today, you may have to undo it in 2 or 3 days. To make the install, copy the files to the project directory you named, and then copy / paste the contents of the aistub file into the app_info.xml file replacing the current section for 6.10. Don't include the first and last line (<app_info> and </app_info>). I'd back it all up first and I usually suspend network communications until I'm sure the change is okay.

Looks like your fixes worked. I was glad to hear you did a reinstall for the video driver - I suspect that driver was the cause, though it is hard to tell with the messages you were getting.

juan BFB thank you
I use here http://www.myfavoritegadgets.info/monitors/GPUMonitor/GPUMonitor.html
For control temperature and GPU load. If I use 5 WUs my GPU load 97/98%
Temperature normal no more than 75 deg Celsius
I think nomber of WUs not depends from CPU/MB/OS. From GPU only.I use ASUS GTX 670 with 2GB memory

Can you post me direct link to Fred performance test?
Thanks

You could crunch 5 or more WU on a 670 (the actual max is the memory avaiable on the gPU) but the overhead to do that makes the total producton worst than with 3. The trick is: use a program that show you the GPU usage (Gpu-z for example) then increase the number of WU until the GPU usage reaches 98/99%, that is the optimal number, more make your entire sistem slower. Or you could use a program like the Fred performance test, it make the test for you automaticaly and indicate the optimal number. On my hosts that number is 3 on the 670, maybe that number is diferent in your host due your particular CPU/MB/GPU/OC combination but you need to test to be sure about that.

juan BFB long time I crunch 5 WUs any time on my GTX670. Works perfect.
I try 6 WUs - not good. My PC freeze periodically. Can you tell me best number. Why you don't try 4 or 5 WUs. Maybe I don't understand something

I think now all OK. I have GPU WUs and no error.
I do follow:
1. Uninstall Lunatics.
2. Uninstall BOINC.
3. Clean all BOINC's folders.
4. Uninstall NVIDIA drivers (usind Driver Cleaner)
5. Install NVIDIA drivers.
6. Install BOINC.
7. Install Lunatics

Still no GPU WUs

You errored out your GPU Wu's from this morning:

Computer 6753440

And you're now down to 11 tasks per day for the SETI@home Enhanced (anonymous platform, nvidia GPU) app version, once a new day occurs (it's ramdomised across hosts), you'll get some more tasks to try.

Claggy

You set your computers to ‘’hidden’’ again.

We can’t help you like that. Don’t worry we will not steal anything.

Tim

And there's nothing of consequence that we can learn from them by them not being hidden, with them hidden we can't alert you to problems if you're our wingman.

Yes with the 670 the best one is the cuda50, you could run 2 or 3 WU at a time, in my 670 i run 3 WU at a time and works perfect.

PSU - very goog. Enough. Be sure. SeaSonic X-660 (Gold)
GPU temperature - normal. Always control it.
Reinstall driver. Waiting for GPU WU. If error still occur maybe rollback to previous version. All began when I install new version.

Tell me I need to install http://jgopt.org ??
I'm advanced in PC and know how manual install.
Thanks

I would definitely go with the CUDA 5.0 version as your card and OS will support it and run quite well.

Can anyone help on this? The app is x41g.

Looks like serious driver/OS crashes, which could be due to a long list of possible issues, just some:
- Some driver installation problem. Could even be the ms-update induced one. Remove driver in safe mode, Clean install (custom option) new driver.
- GPU temperatures, check with a tool like eVGA precision, or msi afterburner
- Card needs reseating
- Power supply failing or insufficient
- system memory failing or needs reseating, or Bios settings
- Application DLLs become somehow corrupted ? Check hard drive integrity and reinstall app
- Some motherboard utility for software monitoring or OC interfering.

Some worst cases that come to mind:
- Motherboard failing
- GPU failing

Probably more basic & worst case scenarios than this. Some diagnostics with other tools might help narrow down the culprit.
