MSI_990FXA-GD65_ATX_AM3_990FX_DDR3MSI 990FXA-GD65 is proposed as high-end motherboard for AMD AM3+ CPU, so compatible with the upcoming AMD Bulldozer. Powered by the AMD 990FX chipset, it has nice features, that we will discuss during this review.

SATA 6Gb/s Test

The SB950 Southbridge is the evolution of the previous SB850, the first AMD chipset to integrate the 6Gb/s SATA standard. The evolution would have permitted an improvement in performance, needed to ensure good performance with 6Gb/s SATA drives becoming increasingly prevalent. We tested the MSI 990FXA-GD65 with an Intel SSD 510 of 250GB. We compared its performance with the one detected on Z68 Intel chipset and on a 9128 Marvell controller of a Gigabyte X58A-UD7.

The ATTO test shows an abnormality with the Intel SSD 510: with files larger than 512k, performance dropped dramatically. The same decrease in performance can be seen from the low values ​​obtained in sequential tests. The causes of this decline are not very clear since the drive showed no problems on other motherboards. At the same time, the board has performed well with other SSDs, as we shall see in a moment. We suppose then a possible "incompatibility" between the SB950 and the Intel SSD 510, or a non-optimal behavior of the two controllers.

Beyond of this little problem the other tests have shown good behavior in tests with sequential files up to 512k, and a small drop in performance on the 4k. Good behavior using the NCQ technology. Once again however we highlight the limitation of the Marvell controller, especially with regard to bandwidth, which is able to provide.

Vertex 3 60GB

Given the problems outlined above, we have carried out tests with a drive equipped with SandForce SF-2200 controller, in particular the OCZ 60GB Vertex 3. The tests showed a linear behavior and normal performance, demonstrating the goodness of the 6Gb/s SATA controller of the SB950.
