Eight P35-DDR2 Motherboards Compared

BIOS And Overclocking

CPU and DRAM voltage settings go way beyond anything needed to extract the highest possible clock speed from an Intel Core 2 series processor and DDR2 memory. A wide range of bus frequency and DRAM ratios also allows you to push to get the most out of these parts.

The IP35 Pro took our aging 3.46 GHz capable Intel Core 2 Duo E6700 engineering sample to an adequate 3.44 GHz at 1.50 volts core and its stock 10X multiplier. Dropping the CPU multiplier to 6X allowed a stable 457 MHz FSB clock (FSB1828) to be reached in this bus-speed-resistant processor.

Abit includes the basic cable kit needed to build a typical upper-range system, with four SATA cables being only two fewer than the six SATA ports.

Abit also puts two IEEE-1394 FireWire connectors and two USB 2.0 ports on the same plate, which saves a slot compared to using separate ones.

The Abit IP35 Pro is available from around $185 at various web stores.
