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.

BIOS Frequency and Voltage settings (for overclocking)
FSB Frequency 100 - 625 MHz (1 MHz)
Clock Multiplier Adjustment Yes
DRAM Frequency 400-1400 MHz Data Rate
PCIe Clock 100-200 MHz (1 MHz)
CPU Vcore Default - +0.3875 Volts (0.0125 Volts)
CPU FSB Voltage Default, +2%, 4%, 6%, 8%, 12%, 16%, 20%
Northbridge (SPP) 1.20 - 1.35 - 1.50 Volts (0.025/0.05 Volts)
Southbridge (MCP) 1.50 - 1.70 Volts (0.10 Volts)
DRAM Voltage 1.800 - 2.800 Volts (0.05 Volts)
CAS Latency Range
tCAS : 1-6 ; tRCD : 1-7 ; tRP : 1-7 ; tRAS : 1-31 ; Command Rate : 1T/2T

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.


Documentation & Software Motherboard Manual
Motherboard Driver CD
Hardware 1x 80-conductor Ultra ATA cable
1x SATA Data Cable
1x 4-Pin to SATA power adapter cable
1x I/O Panel Shield
1x SLI Bridge
1x SLI Bridge Clamp

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.
