The Features

A feature-rich Intel board is hard to come by but with the D845PEBT2, all will soon change and it may be the start of a very exciting line of Intel boards. As some of you may have known by now, Intel is a strong supporter of Serial ATA and it's not a mistake that Intel is integrating a third-party Serial ATA solution in the D845PEBT2. Since the ICH4 does not come with native support for Serial ATA, Intel used the pretty well-known Silicon Image Sil3112a controller to give users Serial ATA connectivity. With this controller, you can expect to perform either RAID 0 or 1 on the drives that's connected to the Serial ATA ports. Offering only two ports, it gives users two extra hard disk ports in addition to the four Ultra ATA-100 ports offered by the ICH4.

For digital video enthusiasts, they will welcome the inclusion of IEEE-1394a FireWire support in the D845PEBT2 motherboard. Although the ICH4 does not come built-in with any IEEE-1394a MAC unlike most third party chipsets, Intel used a third party FireWire solution which is based on Agere's FW323 one chip controller that gives you up to three ports. One of the ports have been integrated to the back panel while two additional ports are found as headers on the board. Unfortunately, no bracket is provided to take advantage of the other two ports.

For overclockers, they'll find a little more tweaks on the D845PEBT2 than the usual run-of-the-mill Intel motherboard. Here, users can expect to tweak memory settings to increase performance and at the same time, there's a Burn-In mode that allows one to overclock the processor for faster performance. What? Intel is allowing overclocking features on their motherboard? Yes, that's right. By allowing users to tweak the front side bus frequencies, users can expect to gain more performance out of the standard processor. Of course, before one gets down to the overclocking, Intel has a whole lot of disclaimers to warn users of such practice. Still, it's rather unusual to find overclocking features in an original Intel board. Does this mean Intel is approving users to overclock the processor for more performance? Well, whatever it is, we think it's one positive step towards the right direction.

Memory timings are now available for adjustments via the BIOS setup menu.


The Burn-In Mode allows one to overclock up to 4% of the default FSB frequency.
