an up close look
at the layout of the Gigabyte GA-P67A-UD4-B3 motherboard. First up,
two physical PCI Express 2.0 x16 slots. A single videocard will run in x16 mode
while two-way nVidia SLI or ATI CrossfireX configurations will split the
bandwidth equally and run both videocards in x8/x8 mode. Remaining expansion
slots include three PCI Express 2.0 x1 slots and two legacy PCI
Spacing between the two videocard PCI Express
2.0 x16 slots is good. Dual-slot videocards only block one PCIEx1 slot. If you
opt for SLI or CrossFireX, that will cost you a PCI slot as well. With either videocard scenario
there is lots of space for cooling and adding in extra PCIex1 cards.
The PCIe slots are clearly
marked with bandwidth values. Along the bottom of the Gigabyte GA-P67A-UD4-B3 motherboard you'll
find a COM port header, (3) USB 2.0 headers and (1) USB 3.0 header (no
bracket included though). There's a good amount of connectivity on the GA-P67A-UD4-B3
motherboard, particularly given that the board has two eSATA III
ports on the rear I/O.
front panel IO header and clear CMOS jumper are the boards' dual BIOS's (backup
and primary), four 3Gb/s SATA II ports (black) and two 6Gb/s SATA III jacks
(white). RAID 0/1/5/10 can be configured across any of these ports.
The Intel P67 Express
chipset doesn't produce that much heat so all it needs is a small, low profile
passive aluminum heatsink for cooling.

all the duties of the Northbridge (memory controller, integrated graphics, PCI Express lanes) has
been off loaded to the processor, the P67 is like a glorified ICH10R Southbridge.
motherboard supports DDR3-1066/1333/1600/1866/2133 memory in a dual channel
configuration. The largest memory density for 64-bit operating systems is 32GB,
for Windows 32-bit you're capped at 4GB max. The four 1.5v DIMMs support Extreme
Memory Profiles (XMP).
Like all Intel P67 platforms, the Gigabyte GA-P67A-UD4-B3 motherboard accommodates
32nm Intel socket LGA1155 2nd Generation 'Sandy Bridge' Core i3/i5/i7
2xxx-series processors and is not backwards compatible with socket LGA1156
The heatsink mounting holes are the same between LGA1156
and LGA1155 heatsinks. As long as aftermarket CPU coolers support one of those CPUs,
it will install on both. If in doubt, have a peek at
Frostytech's excellent Top 5 Heatsink chart.
has a power VRM design built around 'Driver MOSFETs' which combines the
functions of a driver, high MOSFET and low MOSFET into one
small power-efficient board mounted component (hidden below the passive heatpipe heatsinks that surround the
LGA1155 CPU socket).
Here we have the
NEC USB 3.0 controller. 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.
boosts the power capabilities of it's USB ports; USB2.0 from 500mA to
1500mA, and USB 3.0 from 900mA to a maximum 2700mA. Each USB port on this motherboard
is protected from damaging the rest of the system in the event
of a short by a high tolerance solid-state fuse.
