Introduction

This content was originally featured on Amdmb.com and has been converted to PC Perspective's website. Some color changes and flaws may appear.

In the Amdmb.com test lab, we have reviewed lots of motherboards, Gigabyte included. This is our first review of their product in some time and in this form, the GA-7ZXR (2.2), we are looking at a KT133A chipset motherboard with support for 266 MHz FSB processors.


Unlike most motherboards, the revision number on the 7ZXR is very important. Not merely some minor design changes took place between 1.0 and 2.2; in fact, they changed entire chipsets. The first 7ZXR motherboard used the original 686A south bridge chipset. So, instead of creating an entirely new motherboard and model of motherboard, and selling both, Gigabyte chose to have only one KT133A chipset motherboard with the 686B south bridge. Not a bad idea with the costs being merely the same and having the advantages of revision 2.2 being available to everyone.
