help with 5870 + 2x 5830

[Lightspeed]

hey everyone

5870 is hashing away as we speak no problems

as title says, first problem is I cant overclock the 5830s in msi afterburner

second is I cant see my 5830s in GUIMiner do I need to go back to individual batch files again ?

thanks

do you have a monitor or dummy plug in each card?

if not cards without a display or dummy plug attached will not be usable in windows.
the windows drivers disable cards not plugged into anything and will not be listed on GUIMiner

If you do not have a monitor to plug into the GPU's Bitclockers has a guide on how to make Dummy Plugs

You may need to restart the PC to reload video drivers after plugging in the 5830's
