Gigabyte GA-890FXA-UD7 AMD 890FX Motherboard - FIRST LOOK

Gigabyte GA-890FXA-UD7 AMD 890FX Motherboard - FIRST LOOK - PCSTATS
Abstract: We're excited to see what the Gigabyte GA-890FXA-UD7 motherboard is capable of with a 6-core Phenom II X6 1090T chip locked into its AM3 socket....but this article is all about a first look at everything Gigabyte's squeezed in.

Motherboard Walk Around

Multi-videocard Crossfire gaming systems are what the AMD 890FX is built for. The six physical PCI Express 2.0 x16 slots can be run in a variety of configurations depending on the number of videocards installed. Dual Crossfire runs at (x16/x16), triple Crossfire runs at (x16/x16/x8) and quad Crossfire runs at (x16/x16/x8/x8) modes.

In this corner of the Gigabyte GA-890FXA-UD7 motherboard are the six 6Gb/s SATA III ports and the Port 80 card for debugging.

The Gigabyte GA-890FXA-UD7 motherboard comes with this water block attached. We'll talk about this waterblock and the other passive Silent-Pipe heatsink shown below that can be used instead in more detail on the next page.

Gigabyte have another interesting feature that plays off the rear I/O USB ports - it's called USB3x Power Boost. USB 2.0 and USB 3.0 ports natively supply electricity to power external peripherals, but if too many devices or power intensive devices are attached this can cause the USB bus to shut down. Standard USB 2.0 ports are limited to 500mA maximum load, and the USB 3.0 specification increases this to 900mA. On the Gigabyte GA-890FXA-UD7 motherboard both of these voltage potentials are increased, so more devices or things like external hard drives can be powered by the USB ports alone.

USB2.0 power levels increase from 500mA to 1500mA, and USB 3.0 power levels are bumped up from 900mA to a maximum 2700mA. This isn't going to change the performance of any USB device, but it will stop some especially power hungry things like external 2.5 inch hard drive enclosures from conking out unexpectedly and increase overall system stability if you use a lot of USB devices (and who doesn't?).

Now, lets go in for a closer look at that northbridge waterblock and the large passive northbridge heatsink also included with this motherboard.
