so I dont have a resister to make the computer think 2 monitors are attached yet.  (windows 7)

I am now up and running with guiminer at default clocks.

How do I control clocks/fans of each card independently?

I've heard that msi afterburner controls the card that is currently plugged in.  So I should find a stable OC on the first card then switch to the other card and repeat?

How does that work once I have a dummy plug?

It is pitch black. You are likely to be eaten by a grue.

MSI afterburner appears to control same GPU no matter which I plug into.

I want to up the fan speed on the hotter card and I cant.

MSI Afterburner allows you to select each card, and make changes to that particular card independent of other card's settings.

I'm running a 5850 and 5830 on Win 7 64 bit and have no problems setting each card independently.

You will need either a dummy plug, run both cards in crossfire, or connect both cards to a monitor in order for Windows to recognize each card as active.  On my particular miner with this setup, I have one monitor with both VGA and DVI inputs, and just have each card going to each input.

Hope that helps.

OH its in the settings.  Thank you!

Cant seem to change the settings on the 5850 except fan speed.  Core and memory sliders show no value.  GPU-Z shows stock values.

edit: I adjusted the 5850 with sapphire trixx.  both cards running 925.  think I'll leave it here for stability test before pushing any further.

600Mh woohoo!
