Dummy plugs are weird It depends on the driver..

I am runnign a 7950 + a 5850 and my 7950 needs a dummy plug or needs to be plugged in at first or hashes suck....

12.6 beta drivers, cgminer 2.4.2, diakgcn kernel. and phatk kernel..

On my dedicated rig I am running older drivers and they do not require dummy plugs.

Hi, the dummy is required to avoid this:

I have both installed.... What would work better with the 7950 a 6870 or 5850?

Rigs with mixed 7 and 5 series cards will never be optimal Sad

Not true. You can, and should, install 2.1 SDK for the 5850 to mine on, and 2.6 for the 7950. 2.1 is a completely separate OpenCL platform and installs in a completely seperate path from 2.4+. It's VLIW4 hardware (69xx) that is pretty much screwed if you want to use it with GCN hardware, since 2.4/2.5 is fastest with VLIW4, but is incompatible for GCN, and 2.6 is slow as molasses with VLIW4 but is required for GCN.

I tried installing 2.1, but it wouldn't, stating a higher sdk is already installed, 2.5. It's very complicated if you ask me, from looking at the pm's we bounced back and forth.

What if your mixing cards.. I have one 7950 and one 5850 as my desktop card in this rig....

Can you run two SDK's Huh

Running the Catalyst 12.6 beta...

If I hit forward and back in Chrome, my text doesn't disappear and I don't have any addons. I just tested it with this post. What browser are you using?

Firefox, i believe because I have scripts blocked, just came to mind, beat tired.

*shrug* I use 11.12 and 12.1 for all my miners and none of them need dummy plugs.

I wonder if because I have in bios, graphics set to onboard "intel's graphics". But I have it set at this, as explained in op.

But other than that, I've got two cards mining away nicely.

Why would you need to use a dummy plug? Drivers 11.7 and greater dont need dummy plug.

I am using 12.1, for my situation, I pulled my dummy plug, the driver on my operating system spits out [you need ati/amd graphics card for driver to work] in some similarity of them lines. So, without the dummy plugin, the 5850 I have here is undetectable.

I recall last December, when I was mining with two 5830's, I didn't need a dummy plug. & I forgot how to use the function to bypass the dummy plug, I went to extend "i think extend" the card, but there is no extend option in the CCC.

Note: thank goodness for lazurus addon, I almost lost every I wrote above, accidentally hit back button. Such an awesome addon.

I was surprised it didn't work. I made the plug myself with resistors (I'm an engineer not a noob with this stuff) but no go.
Maybe I'll have another whack at it.

I never could get that setup working on my aging Dell. I've tried a plug on the video port and I've tried BIOS settings. But it still complains if I don't have the monitor plugged into the ATI mining GPU card no matter what. So I render on the ATI card and just live with it.

Well if it's Windows, you need a dummy plug on the ATI card.

It's Windows and the dummy plug doesn't work. It's OK I can live with it.

Hm, are you using the correct resisters and/or tried a different plug with the same resistors?

Here is a great guide, if you like to make sure everything is in place correctly.

As it should work.

With it installed, should I have Virtu On or Off? I do not want anything using the 5850 except GUIMiner, of course :p..

Edit:
Very interesting read indeed.

I believe I need it off for what I am doing for the next few months.

Lucid Virtu is also available on some Z75 motherboards.

Sure is available for my board. I was wondering what that lucid was for when I first got this board. Lucid virtu didn't really pop till I seen your last post and had to check the download section.

The only downfall using integrated graphics is that you're going to be consuming a little more power.

That's ok. I'd rather do it this way, so there isn't any interference with my mining
