![]() ![]() The service manuals for your system is found here: Opens a new window ** Please remove the AC power cord before removing any components and take anti-static precautions. ** These steps involve removing components from your system. ![]() In this situation, I would advise you to follow these steps: If you've removed the video card and are still seeing the solid amber power button LED then it is possible that there is a hardware failure causing this issue. So, long story short - if you pop a dual-head card into that second PCI-e slot, you will be able to float 4 monitors (I've got 3 right now). This is supposedly enough bandwidth to run across-the-bus SLI, as the monitors are supposed to be connected to the first card in an SLI setup. The minor drawback is that the second x16 slot is not a real x16 it is only connected as an x4. If you pop your video card into the second x16 slot, your onboard video does not get shut down. Most current Optiplex machines have two x16 slots. Radeons don't have a lot of support for GPU encoding, so I really wanted that HD4000 active and usable, if not driving a monitor.Īfter a bunch of testing and digging through manuals, I found that the motherboard will always disable the onboard video if you jam a video card into the first PCIe x16. This was not always the case, as the machine arrived with dual ATI Radeon cards. I do video transcoding on my work machine (Optiplex 7010), and the onboard Intel HD4000 GPU rips through h.264 encoding at an impressive rate. This is an older post, but I thought I'd throw some info into the pot for anyone still looking. ![]()
