ASRock 939Dual-SATA2 Review

Packaging »


I would like to thank ASRock for supplying the tested motherboard.

The ASRock 939Dual-SATA2 is built around the ULi M1695 Northbridge. As Southbridge the ULi 1567 is used.

What is unique about the ULi M1695 is that it has native support for AGP 8x and PCI-Express x16. Other boards which have both AGP and PCI-E, implement the AGP port via a PCI-to-AGP bridge, which means that all special performance enhancing features of AGP are lost. On these boards AGP performance is quite sluggish.

You can also use both AGP and PCI-Express at the same time to connect multiple displays. It is not possible to run Crossfire or SLI.

In addition to the two SATA ports of the ULi chipset, ASRock has added another SATA-II capable port via an additional SATA controller chip.

The integrated network port is only 100 Megabits capable, but this should be fine for most users of this value oriented board.
