The overclocking features in the 8K5A2+ BIOS make this a pretty good overclocker.
Before even discussing the overclock features, take a look at the picture of the POST screen and notice how Epox thoughtfully placed all this information on the bottom quarter of the screen.

First in the Frequency/Voltage control screen you have the ability to change your CPU clock speed from 0-255Mhz in 1Mhz increments. There you can find a very flexible Vcore tuning control that gives you from 1.400-1.850V in 0.25 increments, and beyond 1.850 all the way to 2.2000 in 0.50V increments. We found this extremely useful compared to the relatively restrictive settings allowed in the KT4 Ultra. In fact, the same locked 2100XP chip that wouldnt POST past 142Mhz core clock speed on the KT4 Ultra was stable in Windows up to 143Mhz on the 8K5A2+ by bumping the Vcore up to 1.750, and would post beyond that (though with stability issues). Also, one thing to note is that the board will allow much higher FSB settings, even those that are unstable, before it finally locks up with a black screen instead of a proper POST.

DIMM voltage can be incremented up to 0.70V in 0.10V increments. And all the adjustments made in the Frequency/Voltage screen are supplemented with info such as the resultant AGP/PCI clock speeds, and the total deviation from default Vcore, I find this to be a very nice visual reminder of just how much youre pushing your overclock, compared to BIOS screens that dont show ANYTHING.
The only thing missing is the ability to either lock your PCI/AGP bus speeds or control your PCI/AGP clock divider manually. The PCI divider is determined by your core clock setting. 1/3 divider at 100Mhz, ¼ Divider at 133Mhz and 1/5 Divider at 166Mhz. The much needed 1/6 divider is absent, meaning that if you plan on your clock speed to pushing 200Mhz, be prepared for a 40Mhz PCI and 80Mhz AGP clock. Imagine trying the boards 255Mhz FSB limit and running your PCI at 51Mhz!
A separate screen allows you to adjust your DRAM settings to your delight. Clock speeds allowed are 133(DDR266) and 166Mhz(DDR333). We had no stability issues with the DDR333 setting.
