EPoX BIOS
Looking at EPoX's BIOS now. This is usually one of their fortes and what's endeared them to enthusiasts worldwide.
The single most disappointing aspect of the BIOS is the relative lack of Vcore. I've manually inputted the highest settings available on Vcore, VDIMM, and VAGP respectively. The memory and AGP voltages are astounding. The VCore maximum voltage of 1.6v, however, is sadly lacking when compared to other EPoX boards and, more importantly, with its competition. We really cannot see why EPoX have limited the Vcore to just above default levels. Hopefully a BIOS release will solve this little problem. Other than that, the voltage and manipulation subscreen is excellent. Under-load voltage closely resembles what's set in BIOS; always a good thing.
CPU FSB can be tuned up to 350FSB. That's not as implausible as it first sounds, especially with an unlocked or lower multiplier P4 'C' CPU. EPoX allow you to manually key in the required settings, such that you don't have to scroll through each one. Memory dividers are simple enough. At 200FSB, you can run synchronous RAM or asynchronously at DDR-320 / DDR-266 speeds. The latter two options negate the performance advantage that the Canterwood can offer, unless you manage an amazing FSB.
Jumperless is the only way to go these days. A decent array of options.
Intel's ICH5/R offers some interesting combinations. S-ATA RAID0 allows you to use both primary and secondary P-ATA channels. Using S-ATA primary in single drive mode precludes the use of P-ATA primary and using S-ATA in secondary mode dictates that you cannot use P-ATA secondary. All of this of little concern when the EPoX features another 4 channels of IDE support.
