yea and i kept raising vcore far past what i needed to be folding and prime stable but dirt works fine lol.

Been folding on 6 cores while running dirt @5ghz and not 1 reboot whatever poem does it hates my pc lol.

So, many many thanks to those who helped me figure out the app info for my Gigabyte windforce GTX 670 2GB OC.

Now that I kinda know whats going on im going to post my results below:
Code:
<avg_ncpus>0.66</avg_ncpus>
<max_ncpus>2</max_ncpus>
<count>0.33</count>
3 work units with 0.66 cpu usage and 87% gpu usage
1322.36 sec = 22.04 minutes
2925.23 credits x 3 = 8775.69 credits
or an estimated 23890 per hour / 573366 per day.
Code:
<avg_ncpus>0.5</avg_ncpus>
<max_ncpus>4</max_ncpus>
<count>0.25</count>
4 work units with 0.5 cpu usage and 87% gpu usage
1,594 sec = 26.56 min
2925.23 credits x 4 = 11700.92 credits
or an estimated 26432 per hour / 634387 per day
Code:
<avg_ncpus>0.5</avg_ncpus>
<max_ncpus>4</max_ncpus>
<count>0.20</count>
5 work units with 0.5 cpu usage and 91% gpu usage
1970 sec = 32.8 minutes
2925.23 credits x 5 = 14625 credits
or an estimated 26753 per hour / 642073 per day

It seems to have peaked here at 5 WU's per GPU although I was watching a tv show during this last test which would have slowed things down some (but more accurately shows how it will perform when you are actually using your pc at the same time).

Hope this helps, please let me know if anyone has any further tips to improve upon this.

So I've run into another issue. I installed a GTX 480 under my 670 and POEM@HOME throws a fit. Now my 670 wont crunch WU's, its just starting them, the count gets up to 1-2 secs and then it starts again. It tries this quite a few times on each unit (5 at a time as im trying to run 5 per gpu) then reports computational error.

Is there something else I need to add to my app_info to specify ram for each gpu or is this just an nvidia flaw in poem that's yet to be addressed?

Till it's fixed I've created exclusions for poem with the 480 so it'll just run primegrid. EDIT - nope that didn't even work, 670 still not crunching... might have to take out the 480 all together

I couldn't feed two cards efficiently, both were strangled by the CPU. Unless you have a 5GHz CPU or a 6C/12T CPU then one card is enough.

I have had to swap my GTX 480 into my HTPC to heat the room and make too much noise biggrin.gif

My HD7950 is way faster on it's own.

But it did work with the app_info sorted.

Hey Jim. It seems that POEM cannot handle 2 Nvidia cards in the same system. It always throws a fit. Even with matched cards like my SLI config. The only thing I found to do, was to disable POEM on one of the GPUs with the cc_config file, and then force poem WU to crunch only on card 0. That is the only way I could get it to work.


However, it seems like sometimes, when the other GPU was working on a different project, the PEOM WUs would hang and not complete. Other times, the single card would finish all the WUs and not pull any more down... Not sure if that is because of 2 cards or shortage of nvidia WUs, but it is annoying.

Seems to me GPU is the best best for Nvidia cards. Decent PPD and no shortage of work

I think NVidia WU's aren't as "common" as we'd like, my BOINC box has had none all day...
