Seven 650i SLI Motherboards Compared

BIOS And Overclocking

One might expect the P6N-SLI to have similar overclocking to its "Platinum" sibling, and it certainly has all the same frequency and voltage options.

While the P6N-SLI pushed the same 3460 MHz limit so often found on the tested E6700 at 1.50V, dropping the CPU multiplier to 6x only resulted in a maximum achievable bus speed of 375 MHz (FSB1500). Buyers with relatively high-multiplier processors probably won’t need a higher bus speed, but this low-cost board certainly wouldn’t drive most low-speed Core 2 Duos to their limits.

Once again we see a barely-there accessory kit similar to that of the ECS NF650iSLIT-A, but it seems appropriate since the P6N-SLI can be found for the same $115 online price.
