Well, at last the mainboards based on NVIDIA nForce started selling worldwide. The first product on this chipset, which managed to elbow its way into the market appeared MSI K7N420 Pro mainboard. At present, it is the only available solution based on nForce. However, there is not so much waiting left before ASUS offers us something cool as well.
On November 19 ASUS officially announced two new Socket A mainboards based on NVIDIA nForce 420 chipset. As it followed from the press-release, these mainboards called A7N266 and A7N266-E correspondingly, differed only by the audio implementation. It was true, A7N266 was equipped with an external 6-channel C-media CMI8738 sound controller, and A7N266-E used MCP-D Dolby Digital 5.1 APU integrated into the chipset South Bridge. This way, A7N266-E simply boasted enhanced audio features. All the other specs of the boards are as like as two peas. They are even built on one and the same PCB. However, as A7N266 doesn’t use the integrated APU it received a cheaper MCP South Bridge instead of MCP-D supporting Dolby Digital 5.1.
Let’s take a look at the details specs and pics of the two products:
