..:: Introduction ::..

In the world of motherboards, few names come to mind when you think of overclocking, stability, and quality. Asus is one manufacturer that has been known in the past, and present, to represent those three ideals. Today, I will be taking a look at the KT266A offering from Asus. The A7V266-E is nearly identical to the previous A7V266. Due to the fact the KT266A is pin-compatible with the KT266, the only necessary update is to the BIOS. To get you better acquainted with the board, here are the official specifications as listed by Asus.
