DD, Look at the link in post 342

DD-you would still need a dummy plug with the new drivers (SLI enabled works now). With the dummy installed, go to your display properties and you should see two monitors (one is your main). With Win7 once you install the dummy plug, it automatically detects it.

This is what your display properties should look like

Sorry bog, BBB's linked post worked PERFECTLY. No diabling SLI, and no dummy plug! w00t!

Edit: Now that FahMon has caught up:

Mighty fine PPD if I may say so myself.

 

[El Fiendo]

Mighty fine indeed! That's good enough for around 12th place in daily production, and all the prestige therein. Pretty damn good for someone who joined up 2 days ago.

 

[thebluebumblebee]

DD, Crank those fans up! Was it "-forcegpu nvidia_g80" that got it to work?

This question has come up several times. I wish someone could explore this further and write a sticky. One of the posts that I just read said that this works for up to 2 cards, but not beyond.

 

[DanishDevil]

Well I don't have the ability to test over 2 cards, but that did the trick

I may be getting a different mobo soon, and I can add my Geforce 210 to the mix and try the trick on 3 cards.

I cranked them to 70% for the time being. You think they need to be spinning faster? 82C should be fine for these cards in the long run I think. Or am I wrong?

 

[El Fiendo]

80C is fine, and I believe what they're designed to be kept around. My fans on auto don't ramp up till just before that, and then usually keep just enough to maintain that temp. However, I pump my fans up to 100% as do most folders. It's a preference thing really.

As for the multi GPU thing and not more than 2 cards, I'd test it for you Blue but I don't have enough SLi bridges (or bridge ports) to test it out. I'm looking at getting a Tri-SLI hard bridge for my i7 rig, so I'll report back when I've tested it out.

 

[DanishDevil]

If I could stand studying with these at 100%, I would

Those same posts talked about SLI now working WITHOUT bridges!! Just uses the PCI-E bus. It complains about the bridges not being there, but works anyway.

So close, but so far from pie

But it's a "white" noise, no?

Oh? So they do. I completely overlooked that. I've put this on the to do list, I'll try and get to it within a week.

 

[bogmali]

Did not know that you could get away without a dummy plug however I've yet to prove the SLI portion is true because none of my cards work without it.

I've put together a system with the following specs:

GIGABYTE GA-MA790X-UD4P
AMD Athlon II X4 630
Team Xtreem 2GB DDR2 800
OCZ GameXStream 700W PSU
EVGA 9800 GTX+
Windows 7 RC

I was able to install Windows 7, video driver, etc and the above system works. I next wanted to install the following GPU before I installed either the WCG or F@H clients:

XFX 9800 GTX+

Now when I start Windows the monitor goes black. I have to remove the GPU before I get the video back. Any ideas?

ps: the PCIE cables are installed on both video cards.

I had that problem once, on a 790 also....there should be a setting in the bios to allow the use of the card. I cant remember what it was called.

After more thought, my issue with the 790 was that I couldn't get two cards to run....sorry

WCG or F@H clients not installed.

As original reported when I added a 2nd card, a XFX 9800 GTX+, I would loose video.

I removed all video cards. I then installed the XFX 9800 GTX+ card in slot 1 and had no problems.

I then added the EVGA 9800 GTX+ card to the 2nd pcie slot. I lost video after I entered my password. The monitor flashed a couple of times then went blank.

If someone asked me this question I'd probably say it's the PSU! Any other ideas?

 

[thebluebumblebee]

Are you sure your monitor is attached to the video card in the "primary" slot? Do you have an extra monitor that you could plug into the second card to see what happens?

 

[bogmali]

Msgclb-I doubt that it is the PSU since it has enough wattage. Try this though, Power up the rig. When screen goes blank unplug your DVI/VGA out put cable and start playing with it by plugging it in the other DVI outputs to see if the video defaulted to the second card. If that is not it then yeah I would check that PSU.

I am running 2 9800 gtx+ with a Coolermaster 500 watt PS and have had no problems with them since I picked em up from Boggy. So might be your PS but its definitely better than what Im using. Good Luck man your PPD has jumped again.

I have to shutdown and move it so I can access the DVI/VGA cable. I'll try that next.

 

[bogmali]

I just had that same problem with my 2nd GX2 when I installed it. The only difference is that I fried a 750W PSU in the process so now that I have Fit's 1KW PSU, no issues. Mine defaulted to the 2nd card when I installed it so I was left pondering what happened to my screen

 

[mx500torid]

I got a problem with 2- 9600 gso i just started. When I run them both Falmon shows both getting about 1900 ppd each, but when i shut one off Falmon shows 3800 ppd on 1 card. Any ideas?

Are you running prifinity? Do you have the GPU flags set correctly?

Virtually identical to what happened when I got my two up recently. It runs both clients on one GPU! Try ""-forcegpu nvidia_g80" with 191.07 or latter. Also, you may want to look at the link in post 342.

 

[msgclb]

I give up!
I also tried two 250 GTS cards and got the same results.
I sent a help message to Gigabyte.
Thanks for any advise given.

I have no idea what prifinity is but i did check the targets and had -gpu 0 and -gpu 1. Thought i set em up the same as the others but I musta done something wrong.
