The Gigabyte GA-A75M-UD2H motherboard has a pair of PCI
Express 2.0 x16 slots that operate at x16 and x4 mode respectively, or 8GB/s and
2GB/s per direction. A single PCI Express x1 and PCI slot complete the list of
Along the bottom edge of the board we find headers for
the following ports: front panel audio, Firewire, (2) USB 2.0, USB 3.0, COM port
and front panel connectors. The GA-A75M-UD2H comes with two 4-pin PWM fan
headers spread evenly around the mATX board. While USB
2.0's 480Mb/s maximum bandwidth was enough for many years, USB 3.0 expands the
bandwidth to a whopping 4.8Gb/s (4800Mb/s) which is more appropriate for today's
large mass storage devices.
Gigabyte has boosted the electrical capabilities of the second USB
2.0 header to support charging requirements of peripherals like the Apple iPad/iPhone while the rest
of the computer is off. This board supports USB 2.0 power demands up
to 1500mA via 'On/Off Charge'.
Six native 6Gb/s SATA III
ports (RAID 0,1,10,JBOD) are supplied via the AMD A75 chipset, five are present
on the board and one is located at the rear I/O for eSATA devices. The
white connector by the main ATX power connector is a printer port header - I
guess the assumption is there are still more than a few parallel port based
printers or scanners in the world.
The AMD A75 chipset is cooled
by a small passive aluminum heatsink, this chipset communicates with the AMD A8
Fusion APU over a Unified Media Interface (UMI) interface at 2GB/s.
motherboard has four 1.5v DIMMs which supports up to 32GB of
DDR3-1066/1333/1600/1866 memory in a dual channel configuration. If used, the
AMD Radeon HD 6550D IGP will allocate up to 512MB from system memory to
A simple passive heatsink cooling the boards' VRM
circuitry and power MOSFETs. Only solid state capacitors are used to
manufacturer motherboards these days.
This Gigabyte motherboard uses Ultra Durable 3 components. With the
upcoming AMD A85 chipset Gigabyte has upgraded this technology collection to Ultra Durable
5. The changes are pretty interesting, if you want to read about
