Seven 650i SLI Motherboards Compared

BIOS And Overclocking

BIOS frequency selections are far more realistic than those found in several competing products, but still go beyond component capabilities. CPU core voltage selection, for example, can push a 1.30V core to 1.6875V, but users who don't know their core voltage will need to recheck the results of any new settings they make. Northbridge voltage range is adequate but far from extreme, while a DRAM voltage limit of 2.800V is far more than what's required to overclock most modules to stability limits.

The P6N SLI Platinum pushed an E6700 previously know for its 3460 MHz stability limit at 1.50V to that same limit, and dropping the multiplier to 6x allowed the bus speed to be pushed way up to 448 MHz.

MSI throws in every potentially needed internal cable except for a second Ultra ATA, and adds an eSATA-to-SATA data cable for external use of internal drives. Round ATA and floppy cables appear impressive at a glance, but are of the low-cost folded variety.

Unique to the P6N SLI Platinum are a USB 2.0 breakout cable features four diagnostic LEDs and a fan kit for the passive Northbridge cooler.

The P6N SLI Platinum can be found for around $150 at various online retailers.
