KT266 Vs. KT266A: Which Is Which?

KT266 boards have been out for a while now. KT266A boards are just beginning to come out.

What’s the difference? Essentially, the North Bridge has been revised to improve memory performance. You definitely want a KT266A board rather than a KT266 board.

As you will see, most mobo manufacturers and/or retailers with current KT266 boards aren’t exactly making it easy to figure out which is which.

So we will.

Abit

KR7A: 266A

AOpen

AK77: 266

Asus

A7V266: 266
A7V266-E: 266A

This one is particular important to note. Both of these are just becoming available. The A7V266 is starting at about $135, which is more expensive than most of the KT266A boards out there. The
A7V266E, which is the one with the KT266A chipset, is available at just one place for $180.

Don’t buy an A7V266 thinking you’re getting the latest for your money, you’re not.
