Thread: ASRock 890GX strong Motherboard

AMD 890GX graphics engine has the similar essential specs as AMD 790GX’s, but being a DirectX 10.1 part, not a pure DirectX 10 part as its older companion. The main diversity on AMD 890GX is the utilizing of a new south bridge chip, identify as SB850. This south bridge chip natively holds SATA-600 ports (“SATA 6 G”) and actually this is the first chipset to arrive on the market with this feature. At present on motherboards based on other chipsets featuring SATA-600 ports an outer controller chip must be used.

The 890GX Extreme 4 motherboard is an improved edition of the 890GX Extreme 3 motherboard, with two extra USB 3.0 ports. The number of interior SATA-600 ports was reduced from six to five, since the sixth SATA-600 port was routed to the rear panel of the motherboard to become an eSATA-600 port (on the Extreme3 the eSATA port is SATA-300).

The audio codec was altered from VIA VT2020 to Realtek ALC892 the manufacturers of both chips don’t publish technical information about these products at their website. All three have 128 MB “Side Port” memory, other than while the Extreme3 and Pro3 models use a DDR-1333 part, the new Extreme4 uses a DDR3-1666 chip (but still running at 1,333 MHz). This motherboard has 128 MB video memory soldered on the motherboard. In Figure 2, you can see the 1 Gbit GDDR3-1666 chip (1 Gbit = 128 MB) in charge of this characteristic.
