Introduction

The KT133A still seems to be the best performing chipset for AMD thanks to the excellent price/performance ratio. AMD Processors gain a lot from high fsbs than a higher memory bandwidth. A DDR board running PC2100 DDR-SDRAM but runs on a 200/100MHz fsb would still seem slow. The C-Type Athlons really got a big boost in performance thanks to the higher front side bus speed. The KT133A also gave life to fsb overclocking which was clearly embraced by the market.

The Iwill KK266 now makes its way into the Planet Savage labs. The motherboard's layout looks similar to the Abit KT7A. The expansion configuration is very much ok for hobbyists and normal users. The 1/6/1/0 AGP/PCI/ISA/CNR expansion configuration won't pose any problems for those people who have many PCI devices or use an ISA expansion card. Northbridge active cooling has pretty much been evident in some KT133A boards but the KK266 only uses a small "greenie" heatsink to cool the northbridge. Keep in mind that the VT8363A northbridge can get quite hot at high bus speeds so active cooling really helps. Space around the CPU socket was pretty fair. The small capacitors seem to keep a good distance from the ZIF socket but still could use more space. The location of the socket may not be good for those who use only a mid-tower ATX case since the cpu would seem to be too close to the power supply and removing the heatsink would require removing the PSU sometimes.

Just like the the Epox 8KTA3 and MSI K7T Turbo, the Iwill KK266 also has a RAID version. You can see the traces for the additional IDE ports and the RAID controller on the motherboard. The RAID version is named KK266-R. Jumpers are present on the motherboard to change some settings. There is a jumper to enable/disable onboard sound, a jumper to set the default fsb from 100 to 133 and a jumper to adjust VIO voltage. Iwill also uses their one-of-a-kind jumpers...they use extended jumpers which make them much easier to remove or reposition. While these jumpers are easy to use, it would still be better if all cpu parameters could be set in the bios.

Features

VIA KT133A Chipset
Support for AMD Athlon and Duron
3 DIMM Slots, 1.5GB Max
1 Universal AGP4X Slot
6 Bus Master PCI Slots
1 Legacy ISA Slot
OnBoard C-Media CMI-8738 3D Hardware Sound 4.1
4 Fan Headers
OnBoard AMI ATA33/66/100/RAID Controller, Supports RAID 1, 0, 0+1 (Optional)

The one thing that makes the KK266 stand out from the crowd is the usage of an onboard hardware sound solution. While many still say that onboard sound is crap, there's really no problem with having it on the board since it can always be disabled.

Bios

Out of the box, the Iwill's bios is boring. Memory tweaks are very much weak in the bios. Of course, with the proper bios updates, the KK266's bios really improved drastically and completed the memory tweaks that users look for under Advanced Chipset Features. What's good is that the settings are visible to the user. Fastest would display (5-2-2), Faster would display (6-2-2). Basically, the bios has all the tweaks that are needed to maximize the performance of the motherboard. Overclocking is done under Iwill Smart Setting. FSB's are available from 100-132 and 133-200 in 1MHz incriments. CPU voltage adjustments are absolute and can be adjusted in 0.025v incriments, just what overclockers need. The maximum voltage supported is 1.85v. The VIO voltage adjustment is done through jumpers which give a +5% or +10% to the VIO. Apparently, the voltages are only 3.3V, 3.4V and 3.45V which seems pretty much lacking.

The motherboard doesn't have active cooling on the northbridge but how high does the motherboard overclock?
