Gigabyte GA-MA785G-UD3H: Specifications

The second Gigabyte 785G board we have in the lab is the GA-MA785G-UD3H. Unlike the UD2H, the UD3H is a full ATX form factor board with a full set of expansion slots including dual PCI-E x16 slots which can be linked together in a variety of CrossFire configurations, with and without the IGP.

The Gigabyte GA-MA785G-UD3H is quite different from the two previous 785G boards we checked out. It's the only one of the three to support AM2 processors and implement DDR2 instead of DDR3. It's also the only board out of the three to not include any SidePort memory and not have an eSATA port. However, to its credit, it's also the only board of the three to boast two FireWire internal headers which in conjunction with the port on the rear I/O allows for up to three IEEE 1394a connectors. While the UD3H lacks an eSATA port, it gets an extra internal SATA port for a total of six.

Other than these differences, it is identical to its stablemate, the UD2H.  Even the bundle is the same, which is somewhat unfortunate since 2 SATA cables is enough for an mATX board, but might come up short for full ATX builds.
