More Than Just a 'Paper Launch': 680i Motherboard Comparison, Part 1

Overclocking

It's manual overclocking all-the-way for BFG's nForce 680i SLI, but not that we mind. Clocked at a perfect 266.6 MHz at default settings, BIOS supports up to a 625 MHz FSB clock (FSB2500) speed, plus the full range of memory speeds and timings.

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)
SPP-MCP HT Link Clock 200-500 MHz (1 MHz)
CPU Vcore 0.50000 - 1.80000V (0.00625V)
DRAM Voltage 1.800 - 2.500V (0.025V)
Northbridge (SPP) 1.20 - 1.455V (0.05V)
Southbridge (MCP) 1.500 - 1.750V (0.025V)
CAS Latency Range
tCAS: 1-6; tRCD: 1-7; tRP: 1-7; tRAS: 1-31; Command Rate: 1T/2T

Our Take

Other testers have found bus speeds in excess of 500 MHz using reference-design boards, but this was not possible using our hardware and Nvidia's recommended settings for everything except CPU core voltage, which we set at a hopefully-safe 1.50V. Perfectly stable at our CPU's max 3.46 GHz clock speed, it failed to go beyond 374 MHz FSB clock rate when we dropped to a low 6x multiplier. Chipset voltages beyond Nvidia's recommended settings did not help, and we even tried adding the active chipset fan and CPU fan draft together.

Special Features

BFG's greatest feature has to be its 24/7 toll free telephone and email tech support hotlines. The company also includes the Ulead VideoStudio 9 SE DVD authoring software, Nvidia's add-on chipset sink cooling fan and the game Ghost Recon Advanced Warfighter.

Most unique of the included components is the two-port FireWire break out cable, while the board only has one breakout connector!
