The BIOS
As far as integrated peripherals and storage options go, the SY-P4I875P is loaded, but what about its BIOS?

In the overclocking department, the SY-P4I875P is both well- and poorly-equipped, depending on where you look. The board's BIOS offers front-side bus speeds up to a whopping 511MHz, which can theoretically power a quad-pumped front-side bus beyond 2GHz. Front-side bus speeds that high shouldn't be a problem for the board's AGP and PCI busses since they can be locked down to 33/66MHz, 36/73MHz, or 40/80MHz for AGP/PCI, respectively. However, users will likely run into problems since the board only offers memory bus multipliers of 0.8, 1.25 and 1.33.

The most glaring overclocking-specific shortcoming in the SY-P4I875P's BIOS is a processor core voltage limit of only 1.6V. Since the board's manual clearly states that core voltages beyond 1.6V are not supported, I wouldn't expect a future BIOS revision to bump up that ceiling, but the current BIOS release will let users drop the core voltage in 0.05V increments down to as little as 1.3V. DRAM voltages can be set between 2.7 and 2.9V, and AGP voltages range from 1.6 to 1.8V, both in 0.1V increments.

A standard set of memory and AGP tweaking options appears in the SY-P4I875P's BIOS, but safety features are unfortunately quite lacking.

The SY-P4I875P's BIOS features no fan speed, failure, or even temperature-triggered shutdown or alarm conditions, which is quite disappointing. For mainstream users, such safety features may not be as important, but they're all but essential for overclocking enthusiasts who push system cooling to its limits. With the SY-P4I875P, users will have to rely on the Pentium 4's internal clock-throttling to save the day in the event of a catastrophic cooling failure.
