DFI NB70-SC i845D socket 478

Monday, January 21, 2002


DFI, a manufacturer that most of our readers are familiar with by now, has always stood as a top-tier OEM manufacturer, particularly in the eyes of systems assemblers. Of course, this reputation didn't develop out of thin-air, DFI has worked long and hard to establish a pattern of quality in its product-line. The DFI NB70-SC is the latest addition to their catalog, and is expected to stand as yet another shining example of DFI's technical ability.

Though sober in design and appearance, the NB70-SC is in fact one of the fastest Pentium 4 boards we've tested to data. It is based on the Intel i845D chipset, and thus implements DDR-SDRAM in its memory sub-system.

That's just the slightest overview though, so let's say we skip the formalities, and get right down to the thick of things...

Characteristics of the DFI NB70-SC
-Supports Intel® Pentium® 4 processor in the 478 pin package.
Intel® 845D (593 FC-BGA) Chipset
Form factor

100MHz to 132MHz in steps of 1MHz
Vcore adj.
Vio adj./Dram
Audio chipset
integrated into chipset


Configuration of the NB70-SC is a simple affair. Asides from JP2, which can be used to set the FSB to 100MHz or 133MHz, there are no on-board jumpers to speak-of. In short, all neccessary or desirable adjustments are performed from within the BIOS.

From within the "Frequency/Voltage Control" menu, for instance, it is possible to adjust the clock multiplier, and the FSB frequency.

The "Advanced Chipset features" menu, on the other hand, is used to tweak various memory parameters, and little else.

Clearly though, this board was not designed specifically for Overclockers. That fact is readily evidenced by the lack of options for tweaking the Vio and Vcore voltages, or other features of that nature.
