AMD A85X Mobo Roundup: ASRock, Gigabyte, Asus

ASRock FM2A85X Extreme4-M

The Asrock FM2A85X Extreme4-M is the only micro-ATX motherboard in this roundup, and at $90 it’s much cheaper than the other two boards we tested. Despite this, the board looks great, with a black PCB and black plastic bits. The southbridge cooler has a subtle gunmetal grey color with gold ASrock logo.

It has many of the same features as the other boards, but only two PCIe x16 slots. The second physical x16 slot only operates at x4 speeds, so this is not a board to use if you want a high-powered CrossFireX setup--even though the board “supports” up to Quad CrossFireX. Since Virgo is meant for builds with integrated graphics, this isn’t a big loss, but it’s worth mentioning, especially since FM2 is supposed to default to x8/x8 if both x16 PCIe slots are populated. The board also has seven 6Gb/s SATA ports--the eighth is an eSATA port in the mobo’s I/O panel. The only rear panel outputs missing from the ASRock board are DisplayPort and a second pair of USB 3.0 ports. 

Asrock bundles the board with plenty of additional software, including a program called “XFast RAM,” designed for 32-bit systems with more than 4GB of RAM, to allow the unused memory to be used as a RAMdisk. It also has XFast LAN--designed to optimize Web traffic--and XFast USB. Overclocking tasks are handled in the OS by Asrock’s Extreme Tuning Utility.
