The MSI MS-6339 with its multicolored status LEDs makes for an unusual design. The mini-diodes have been placed next to the COM interfaces so that they can also be seen from behind. The board earns a few points with its well-placed special P4 bus bar. There won't be any problems here with power cables that are too short for a spacious PC housing! On the other hand, there doesn't seem to be any purpose in supplying the board with a CNR slot. It has no business being on an expensive Pentium 4 board. Why would anyone who uses or buys a Pentium 4 with 1300 or 1500 MHz ever stoop to using a low-cost solution like a CNR modem or a network card?

Our testers came up with inconsistent performance results when using the BIOS of two different vendors. After the results with AMI-BIOS had been so terrible, the manufacturer reacted promptly, supplying us with a BIOS version from Award. When using this BIOS, the board managed to catch up with its competitors. Despite the fact that the differences between the separate boards are minimal, MSI ranked very low, even with the new BIOS. Overclocking fans aren't going to be all that excited about this MSI board - It lacks any possibility for overclocking.
