Gigabyte GA-P55M-UD4 Micro-ATX Motherboard Detailed

btarunr · Jul 13, 2009

One of Gigabyte's first LGA-1156 motherboards in the micro-ATX form-factor, the GA-P55M-UD4 was previewed by CPU3D.com, revealing an upper-mainstream motherboard sporting all the essentials and a little more. The CPU socket is powered by a lavish 14-phase circuit, cooled by independent VRM heatsinks. The CPU is wired to four DDR3 DIMM slots for dual-channel memory. The expansion slots on this board include two PCI-E x16 slots (electrically x8, x8 when both are populated), one open-ended PCI-E x4 slot, and a legacy PCI slot. The P55 PCH provides five internal SATA II ports (blue), and one eSATA port on the rear-panel. An additional controller provides two SATA II ports (white) and the legacy IDE connector. 8-channel HD audio driven by Realtek ALC889A codec, one gigabit Ethernet interface, two Firewire ports in all, and 14 USB 2.0 ports make for the rest of the feature-set. It makes use of Gigabyte's Ultra Durable 3 construction. The GA-P55M-UD4 will be part of Gigabyte's first wave of LGA-1156 motherboards.

Looks promising, Mr. Blurrycam II (who is slightly more focused than his father). Odd looking heatsinks. I can't wait to see a UD5 or UD6 mATX board from them!

It lacks the ONFI port which can be seen here:

it seems whenever they use the orange slots it means the cheaper (value) one? I just notice on both platforms. Maybe theres another Micro 55 too.

DanishDevil · Jul 13, 2009

The easiest way to tell with Gigabyte is by the ending. UD4 is Ultra Durable 4. They have released UD5 and UD6 versions of their boards, and the higher the number, the higher-end board.

yeah i figured something like that too i just didnt post it

but if u look also u will ntice all the lower vers have an orange slot (atleast that marketing is consistant and not all over the place)

well, the orange (and red) slots for RAM is about the DDR that you can use... the combination red/orange is for DDR2, and white/light-blue is for DDR3... i see this in AMD Mainboards with 790X chipset...

in the PCI-E, the orange means 8x and light-blue means 16x (CF 8x-8x)

PD: i don't speak to much english, that's why i don't know how said the right colors

, forgive me :'(

my_name_is_earl · Jul 13, 2009

Awesome, no NB heat to worried about. But I'll wait for Larrabee to show up because everything you buy these day seem to be obsolete pretty soon.

Kitkat · Jul 13, 2009

so its the cheaper one.

DanishDevil · Jul 13, 2009

Yeah, but because it's mATX, they may never release a UD5 or UD6 version. But they will if they know what's good for 'em!

phanbuey · Jul 14, 2009

is this SLI compatible as well? or is that only for the 1366?

DanishDevil · Jul 14, 2009

Good question.

DanishDevil said:

No... wait... its not. Just read the SLI/Crossfire stamped next to the second PCI-e slot :slap:

.

Sweeeeeet... may be getting one of these if the LGA 1156 can OC to 4.2 or so on water. Otherwise new GFX cards for meeeeee.

DanishDevil · Jul 14, 2009

LOL we fail.

Whats with all these newer motherboards and the retarded board heatsinks??? Wouldn't something like Asus P5Q-Deluxe copper fin design be the best? or at least Al fin for cheaper boards? Seems strange that they make weird thick heatsink designs to me..
