DFI has earned its reputation of the maker of high-quality overclocker-friendly products with its mainboards for AMD processors. Each new product from this brand is now received with high expectations by the overclocking community. We are trying to do our best to keep up with DFI's product range and review the worthiest samples.

A couple of months ago we got a DFI Infinity 975X/G mainboard based on the Intel 975X Express chipset and compatible with Core 2 series CPUs. Expecting to find it worthy of an overclocker's interest, we put it into our testbed right away but were bitterly disappointed. Created by DFI's best engineers, the mainboard didn't do well at overclocking. Frankly speaking, it provided mediocre overclocking opportunities, obviously insufficient for us to recommend it to true overclockers.

Luckily, DFI doesn't stop to work on a product after its release as some other manufacturers do. When we returned to the mainboard later, we found it greatly changed. The developer had managed to considerably improve its overclockability by issuing a few BIOS updates. Right now, the DFI Infinity 975X/G is surely a worthy product to be tested in our labs, especially as it is one of the cheapest i975X-based mainboards that supports the full range of Core 2 Duo, Core 2 Quad and Core 2 Extreme processors as well as ATI CrossFire technology.
