Overclocking

As most first-generation motherboards of a new chipset, there are minimal overclocking options available to the user. Primarily, there is the ability to modify the FSB of the CPU clock. The following frequencies are available: 95, 100.7, 100.9, 103, 105, 110, 115, 133 MHz. With only 8 available settings, the user does not have a wide range of FSB with which to find their systems peak. In other words, if you can get a 105 MHz, FSB to work, but not a 110 MHz, you don’t have any options to try 106, 107 MHz, etc.

There are two major drawbacks for overclockers: the lack of voltage selections and the lack of multiplier adjustments. Unlike the latest KT133 motherboards such as the Asus A7V and the Abit KT7, as well as the MSI K7T Pro 2-A, which have multiplier jumpers or BIOS settings, the Gigabyte 7DXC does not. However, without the ability to adjust the voltage of the processor, the multiplier and FSB settings will not be as useful anyway.

One other feature that I wish was included, but is a lack of the AMD 760 chipset, is the memory speed differential (the FSB + 33 setting). This would have allowed users of the 100 MHz FSB Athlon processors to fully utilize the PC2100/DDR266 DDR memory. As of now, unless you can find one of the 133 MHz FSB Athlon processors, PC1600/DDR200 memory is all that is necessary. Buying PC2100 for future upgrades is of course always recommended.

Well, lets see how this motherboard performs now, shall we? Here are the system specs for the test system we used on all the benchmarks:
