Gigabyte EP45-UD3L Motherboard
Slots
Contents
Unlike EP45C-DS3R, EP45-UD3L has only one PCI Express x16 2.0 slot, so it’s impossible to use SLI or CrossFireX setups. It also has two PCI slots and four PCI Express x1 slots.
Pay attention in Figure 3 and you will see serial and parallel ports headers. These ports aren’t present on the motherboard rear panel, however you can buy I/O brackets and install them in order to use these ports.
