The heart of the mainboard is based on VIA (KT333/8235) chipsets. Support for DDR-400 memory, ATA-133 and 266MHz FSB with excellent performance honestly are the keywords here. The North- and Southbridge (KT333/8235) performance is awesome as we will demonstrate in benchmarks later on.

The board is equipped with 3 DIMM sockets for up to 3GB of memory.

As stated this is a DDR400 compatible mainboard .. to be honest that's a little deceiving as it truly supports 333MHz out of the box. You will not find BIOS settings that enable your memory to work at 400 MHz. It does support it though, when you for example overclock the FSB the memory frequency will rise along with it resulting in a higher clocked memory frequency. This really is something that needs to be fixed or taken out of their marketing strategy.
 

The layout that Albatron has used is a 1/6/1 (AGP/PCI/Riser) that a lot of other vendors are producing.

Layout wise certain things can be improved a little. The space surrounding the CPU needs to be a bit bigger in size, you will not be able to place the somewhat larger heatsinks on this mainboard as the capacitators are to close to the CPU Socket. For example I was not able to place a large silver Orb onto the Socket A.
 

Not a lot of space around the CPU socket prohibits large cooling units to be mounted.

There is another slight flaw in design though, just in front of the mainboards power connector there is a jumper to set the FSB to 100/133/166 MHz. That jumper is too close to the connector once it's hooked up you will not be able to switch the jumper or pull out the connector easily. Take a look at the images and see for yourself.
 

That jumper is too close to the power connector.

A very interesting function of the KX400+ Pro is that is that it includes a "Bios Mirror" feature, which in all honesty is very similar to Gigabyte's "Dual Bios". "Bios Mirror" is always nice for the people that tweak their bios and like to flash it often, having a backup will save you the time you'd have to wait for your motherboard manufacturer to send you a new one. It works rather simple, if your BIOS somehow got corrupted you move a switch and your system boots from the backup BIOS. I actually prefer the switch over Gigabyte's solution which needs the system to post.

Integrated Dolby Digital 6-Channel sound
The KX400+ has integrated sound through the6-Channel AC’97 Audio via the Realtek 6ch controller. In all honestly, not bad at all. Sound was peachy fine and in games we heard no problems. It fully supports EAX and EAX2.

Overclocking can be done from the BIOS. I must state that Albatron managed to do a pretty good job here. Overclocking is easy and flexible. It lacks a few options for the hardcore overclocker like AGP/PCI dividers though.
