TweakTown have posted a review of the ECS K7VZA KT133A motherboard. Normally ECS are known for producing OEM based motherboards, however this mothrboard is certainly very different; it was the fastest KT133A motherboard tested in the review! Here is a snippit:
The ECS K7VZA is rather lacking when it comes to the overclocking side of things. No CPU multiplier adjustments, no Vcore or VIO adjustments. The only overclocking feature is the ability to change the FSB and even that was limited. In settings we weren't able to get the ESC to go past 133MHz FSB (266 DDR).
