Zotac GT 430 PCI slot GPU info

[Crazybob's Son]

Disabling the onboard in the device manager did the trick. Was a little newvous at first, when it didn't post to either adapter. The n I noticed machine was accessing network, so tried the new card again and there it was. Thanks DP! Thought I was going to be SOL on this one.

Yep! between his computer and mine we put up an additional 175,160 credit. Looks like they are getting 8,758 credit/wu and taking roughly 3hrs per wu.

Sweet! That's a nice chunk o' credits for the team. Great increase!

added the second card to my 6 core. Already has a GTX460 in it. Device manager recognizes it. GPU-Z says it is under 99% load, but the CUDA check box is not checked and BOINC says the box is only running 1 instance of PG. I have a CC_Config file to tell it to use all GPU's. Didn't see anything at PG to tell it to do the same. If I pull up the box at PG, it only lists the 460. Any clues?

Not sure. I would hazard a guess that the the nVidia driver needs to be reinstalled and or project needs to be reset. In that order. And remember to use Driver Sweeper.

Edit: Try extending your desktop first. Normally not required for nVidia but in rare cases it helps.

Yeah i've had to reinstall drivers when adding a second card, even though it's the same driver. It's like it sets itself up only for the exact number of cards in the system at the time of installation.

Still screwing with this thing without any luck. I disabled the 460 and rebooted. Boot-up was to the 460 and then switched to the 430, so it does work. GPU-Z says both cards are under 99% load. 1 Instance of PG running. Attached to Dirt to see if maybe the 430 wouldn't crunch PG. Restarted BOINC. Wouldn't connect to DIRT. Re-enabled 460. Rebooted. BOINC had acquired a SL of DIRT, but was only crunching 1 DIRT WU and no PG. Clicked on NVIDIA icon ib systray. Says the 430 is for display 2, and 460 for display 1, is this significant? Running out of patience with this.

What doe BOINC say about the card in the Event Log? Is it recognized as existing since everything else sees it?

[Crazybob]

It says Nvidia gpu 430 not used, Not sure why?

Add the following to your cc_config.xml file

<use_all_gpus>1</use_all_gpus>

<use_all_gpus>
If set, use GPUs even if they're not equivalent to the most capable one. New in 6.6.25

Note: 1 = Enabled, 0 = Disabled

I KNOW you should have to do this with Nvidia...but I swear I had to do it once when I added a 2nd 570. Plug both cards into a monitor or use a dummy plug. Yeah, yeah, I know, but humor me. It sounds like you covered all the other bases. I came in late on this so sorry if I missed it..you did extend the monitor onto the 430? Sorry if everyone thinks I'm crazy, but this truly worked for me once. I haven't had to do it since. What do you have to lose, but a couple of minutes.
