When I tried to hook it up, I noticed that the DVI connectors on the R9 290 do not have the 4 holes for the analog VGA signal so my dummy plugs do not fit.
Now I'm testing it with the monitor hooked up to it but eventually I want to install 2 of those cards and run the monitor off the integrated onboard GPU (if I use a monitor at all).
If I do not install the dummy plugs or a monitor, I can mine on the R9 290 but it will not let me read the temps, fan settings etc.
Any suggstions how to get this working?
Check your motherboard, most motherboard have slot which you do not need dummy plug and some needed... So you should be able to run 2 with only 1 monitor....
