Gigabyte GA-890FXA-UD7, GA-880GMA-UD2H motherboard listing
Bit-Tech.Net has recently obtained two new motherboards of Gigabyte, model "GA-890FXA-UD7", "GA-880GMA-UD2H", based on AMD 890FX, 880G chipset. GA-890FXA-UD7 positioning high-end players, followed by the third UD7 masterboard after EX58A-UD7, GA-P55A-UD7, is also the first one on the AMD platform, although there is no exaggeration in the specification, but Also known as quite rich.
This motherboard supports the AMD AM3 series processor (including the upcoming six-core PHENOM II X6), while seeing a small problem in layout design: eight-needle secondary power supply interface is masked after the heat sink, it may be more compared Father.
The expansion slot has a PCI and up to six PCI-E X16, but the bandwidth is different. From the top, X16, X4, X8, X4, X16, X8 are respectively. Although the number of slots is much, the layout is reasonable and multi-double slot graphics card can be used. In addition, Gigabya is still very persistent to retain IDE and floppy-drive interface. I don't know how many high-end players need them. Be
The SB850 South Bridge used by the 890FX chipset supports the SATA 6Gbps standard, so six SATA 6Gbps interfaces (blue) are available on the motherboard and extended two SATA 3Gbps interfaces (white).
The memory slot is four standards, supports dual channel DDR3, with a frequency up to 1866 + MHz. There is also a boot and restart the shortcut button.
The back interface is very complete: PS / 2 (mouse), rays and coaxial S / PDIF, six USB 2.0, two USB 3.0 (blue), two ESATA / USB, two IEEE1394A, two RJ-45 (Realtek Gigabit NIC), six 7.1 channel audio ports.
Like the previous UD7 level motherboard, Gigabyte also installed a water cooler on the North Bridge, but basically only symbolic meaning, because it is not integrated, but two synthesis, the thickness is not enough one centimeter, Note that the red arrow is indicated, how much heat dissipation can be hanging up to the motherboard?
In addition, Gigabyte also provides a "Silent-Pipe" radiator, which can replace the water cold head on the North Bridge, but it seems that the heat dissipation effect does not seem to be too good, and it will not affect the first PCI-E X16 slot installation. The graphics card should also be able to undertake the heat from the graphics card.
GA-880GMA-UD2H is a Micro ATX small board motherboard, which is low-end, so the specifications are very inferior, but the cost and price will naturally be relatively low, and the overall looks like the 785G motherboard before Gigabyte.

The AMD 880G chipset integrates graphical core Radeon HD 4250, frequency 500-700MHz, basically and 785g Radeon HD 4200, which is also from RV620, support DX10.1, 40 flow processors.
The processor power supply design is 4 + 1 phase, and MOSFET has been upgraded, but because it is not the final retail version, the heat dissipation plan is not complete.
The expansion slot has a PCI-E x1, two PCI-E X16, a PCI, but the bandwidth of the second PCI-E X16 is only x4, and dual card crossfire is not supported, and the North Bridge radiator is designed, PCI-E There is no problem with a longer expansion card on the X1 slot.
The memory is also four dual-channel DDR3 slots, with a maximum frequency of 1800 + MHz.
Since it also matches the SB850 South Bridge, there is also a native SATA 6Gbps support, but the new interface is only arranged, and there is an ESATA assigned to the back. In addition, the IDE and floppy drive interfaces are also "the soul of the soul".
Back interface: PS / 2 (mouse), fiber S / PDIF, VGA, DVI, HDMI, four USB 2.0, two USB 3.0, IEEE1394A, ESATA 6GBPS, RJ-45, six audio ports. Technology area
