Introduction

Intel's Pentium 4 processors seemed to have a hard time selling at first because of the lack of choices for its chipsets. People who use Intel processors would generally want an Intel-based board to go with them. At first, there was only the i850 + RDRAM combination which proved to be a very fast and stable solution but was pretty expensive. Intel wanted to bring the Pentium 4 to the masses by making a PC133 chipset which was the i845. But the i845 proved to be the worst thing that the Pentium 4 could have since its architecture required a high memory bandwidth...the i845 only provided a measly 1.05GB/sec peak bandwidth. DDR chipsets from VIA and SiS proved to be a threat to Intel because of the price difference between DDR-based chipsets and Intel's own i850. Intel released, for the first time their DDR chipset for the Pentium 4 which is basically a DDR version of the i845. It was called i845D. Benchmarks showed that the i845D could keep up with the i850 and VIA's and SiS' offerings. Add that to the reliability of Intel chipsets and Intel once again had things going well for them. Many board makers started making boards based on the i845D chipset and it did prove to be a very good and reliable solution.

Epox's 845D: 4BDA

Like Abit, Asus and MSI, Epox is also experimenting on their products by providing a pretty versatile lineup, composed of different variations of different chipsets. The 4BDA can probably be described as very straightforward motherboard. It only carries with it the bare essentials but does have some pretty good punch in it.

In typical Epox-style, the board comes in the army green color. One thing worth mentioning is the very nice box that Epox made for the 4BDA. First glance, the board has a neat layout and provides ample space for the different peripherals. The 4BDA only has 2 DDR DIMM slots but this follows Intel's reference design for the 845D. 6 PCI slots are no longer new today and Epox threw in a CNR slot. The common problem with most motherboards is the space from the DDR DIMM slot and the AGP slot but it's a good thing that the AGP slot is spaced away nicely from the DDR DIMM slots. The northbridge is cooled by a small green heatsink which resembles those used on most 440BX motherboards.

The northbridge heatsink is small but it is good enough to keep the whole system stable and running. As seen at the picture at the right, there's not much problem with the layout. The ATX power connector might cause some problems since it may need to go over the fan of the heatsink.

Like most Epox boards, the 4BDA has a RAID version which can be seen from the layout. There are traces for an onboard RAID chip as well as traces for additional IDE ports. The board lacks Epox's usual onboard debugger which does help in diagnosing the board when there are some problems. Overall, the layout is very nice but as always, does have a flaw at least. The flaw is minor though and won't really pose a problem.
