The KK266Plus is able to beat out it's older brother in almost every gaming benchmark. Also, the benefits at higher bus speeds are illustrated quite nicely.

I never thought it was possible that a SDR-based motherboard could be faster then my old KK266-R!

This very cool northbridge heatsink is not shipping with the KK266Plus, but can be ordered from IWill for $6 USD. I you want one, contact cooler@iwillusa.com

With the increase in speed, Iwill continues to offer excellent stability which seems to be a continuing trademark of theirs. However, not all things are rosy. My biggest qualm with this board is the placement of the ATX power connector. Like the floppy/hard drive connectors, I believe they were in the perfect spot on the KK266. Now the placement just impedes air flow.

Also, more of a minor detail, I don't really understand why they couldn't go that extra step and add some thermal material between the northbridge BGA chipset and the heatsink. During testing, it did get quite hot to the touch.

While overall, I am very pleased with the sheer speed of the board (it is ungodly fast), I have to wonder why IWill has decided to have another "go" at the KT133A chipset. The older KK266 didn't have any challengers for the speed tittle (in it's class) so why the rehash?

To summarize, anyone about to build a system really should consider going DDR, however if you are going to get a SDR setup, look no further then the IWill KK266Plus. It's the fastest KT133A board around that I've seen and it's stable enough for the most demanding tasks available. In short, this is simply one blisteringly fast, and totally sweet board!
