The Iwill KK266Plus KT133A Motherboard
Its Nice, but DDR is here...

Recently, we were presented with the opportunity to review one of Iwill's Socket-A motherboards.  We haven't had much experience with Iwill's products here at HotHardware, so we jumped at the opportunity to get their KK266Plus in our lab.  There is no denying that Iwill has made quite a splash lately, releasing a string of high performing, well equipped motherboards targeted directly at the enthusiast market.

The board we'll be taking a look at today, the KK266Plus is a "revamped" version of their original KK266R, based on the VIA KT133A chipset.  The KT133A has been very popular among the overclocking community, but has been overshadowed by the wide variety of DDR capable chipsets available today.  Let's dig into the KK266Plus and see what it's capable of, and find out whether or not there is a place for this mobo in your rigs...

The Iwill KK266Plus ships with a "standard" bundle.  With nothing to truly differentiate it from competing products.

In the box you'll find a driver / installation CD, an 80-Conductor UDMA/100 IDE cable, a floppy cable, an above average user's manual and the 2-port audio bracket and connector cable necessary to fully utilize the on-board audio. The KK266Plus also has headers for additional USB connectors, but unfortunately the necessary hardware needed to take advantage of these connectors is not included.


Installation of the KK266Plus is very straight forward.  There are only three jumpers that may need to be set...one to enable or disable the on-board audio, and another to set the default FSB of your CPU.  Although FSBs can be altered in the system BIOS, their range and divider is affected by the setting of the jumper.  If the default FSB is set to 100MHz., FSBs from 100MHz. to 132MHz. will be selectable.  If the jumper is set to 133MHz., the FSB can be cranked all the way up to 166MHz. The third jumper allows users to adjust the Vio voltage to either +5 or +10%.

Because the KK266Plus complies to the ATX standard, physical installation is as easy as lining up a few stand-offs, tightening a few screws and plugging in the power supply and switches...just like virtually every other motherboard currently available...
