The X58A-UD9 is a big board, as we mentioned before. It is actually too big to fit on our old High Speed PC workbench. We had to move it back quite a bit to ensure that it would fit properly. It is also a rather heavy board and one that has a few surprises in store for anyone setting one of these up.
One of these we mentioned in the board layout section. If you are looking to use the extra power headers then you will more than likely not be able to use the SilentPipe II cooling and will either have to let the Northbridge try and stay cool as-is or you will need to run some water cooling to it. Thankfully it can do a pretty good job of keeping cool on its own without the SilentPipe, but it would be nice to have this option available.
Other items of interest relate to booting and installing software. If you are using a USB KVM (Keyboard, Video, Mouse) switch, you might not be able to boot from a USB thumb drive or from a USB DVD/CD-ROM drive. We ran into this and found that our model of KVM was not compatible with the USB ports on the UD9. As long as our KVM was plugged in we were not able to boot from any USB device. Fortunately this issue is not common; it is just something we felt you should be aware of.
After these minor issues things went very smoothly and we had the X58A-UD9 humming along fairly quickly.
