As we already said, this is the UD4 series' big brother, so you get three PCIe x16 slots, which run either at 2x16 speeds or 1x16 and 2x8 speeds. The PCIe x1 slot is blocked by the massive heatsink, so only small cards will fit. The PCIe x4 slot is open, so even bigger cards will fit in nicely.

This board does also not feature native eSATA ports, you need to use the bracket. If you do really use a triple SLI setup you can forget about putting the bracket in, because some compoents will hinder you to do so. So it's time Gigabyte changes its mind and does the smart thing by putting them on the backpanel.

Gigabyte was the only vendor not considering a debug-LED, but yes, this board does have one. But of course Gigabyte forgot the code to activate the CPU temperature after booting into an OS. The BIOS settings are also very crude. Besides, nobody wants to boot from a floppy, also to disable USB keyboard support is one of the most stupid things we saw. 

For some reason this board is heavily factory overclocked, and we don't like that.






Overclocking:

The UD5 is the same story as with the UD4, auto-settings for overclocking is not an good idea. Lowering the VCore for the i7 920 to 1.2750V and reducing the VCore of the i7 975 to 1.2625V again.
