Abit KN9 Ultra
Starting with the DDR2 system memory in the upper right hand corner, the KN9 Ultra supports four 240-pin DDR2 DIMM sockets up to DDR2-800 speeds. The maximum memory capacity supported is 8GB. These memory slots are colored similarly to those found on the Abit AW8 and AW8-MAX. Running along the edge of the PCB is the 24-pin power connector and IDE ATA-133. Beneath the memory sockets is the MCP55 Ultra Chipset.
Since it had premiered on the Abit IC7-MAX3 back in the Canterwood days, Abit's OTES has continued to expand beyond the original design found on the MAX3. With the Abit IC7-MAX3, OTES had cooled the MOSFETs as well as the i875P Chipset. Since that legendary motherboard, Abit had revised the design with Silent Q-OTES, which uses heatpipes for transferring the heat to the rear of the computer. With the KN9 Ultra, Silent OTES begins at the NVIDIA Chipset with a small passive heatsink and a single heatpipe that loops its way around the motherboard until nearing the I/O panel. This larger heatsink removes the heat from the heatpipe, and the heatsink is placed on additional power circuitry. Since Abit had initially launched OTES we have seen other manufacturers follow suit with various motherboard-cooling adaptations.
