Introduction, Features

Intel has recently launched their first 533 MHz system bus CPU, the Pentium 4 Northwood “B” line with currently 2.26, 2.4, and 2.53 GHz processors. At the same time they upgraded their 845 and 850 chipsets to accommodate the new 533 MHz system bus processors. The Intel 845 chipset comes in 2 new flavors: the 845E and the 845G, the later one featuring an integrated graphic core. Both chipsets share the same Southbridge. The new Pentium 4 Northwood 533 MHz “B” line has become immediately an attractive choice and is obviously causing many AMD fans to reconsider their options. Naturally mainboard manufacturers rushed out their boards for this new promising CPU line. ABIT for example, the Taiwanese manufacturer is offering several platforms for the 533 MHz Pentium 4: an 845G based board, the BG7, and several 845E based boards, the IT7, the IT7-Max, and the BD7-II. The IT7 is a non-legacy board packed with features like 4-channel RAID, whereas the BD7-II is plain vanilla legacy. Today we have closer look at the BD7-II. We will in particular examine how far the BD7-II can be overclocked and how it is performing under such conditions.

The feature list shows that the BD7-II RAID has nothing much to offer above standard. USB 2.0 is already a standard feature and the same goes for the LAN controller. The 6-channel AC97 audio works sufficiently. It is naturally not providing concert hall atmosphere, but who is listening to Beethoven or Rimski-Korsakoff with his PC speakers? We want to hear the bad guys approaching from behind when playing “Soldier of Fortune”, and that is what we hear indeed. In case the BD7-II user wants to utilize the chip's 6-channel function, the line-in and MIC-in ports have to be reverted to line-out channels to get a signal for the rear and center speakers. This is done via Realtech’s propriety software provided by the BD7-II installation CD.

The BD7-II RAID comes with the Highpoint 372 on-board 2-channel RAID controller. We have tested this controller on other boards with various HDD and found it to be a fast and reliable solution. We clearly prefer the HPT372 to the Promise onboard controller used by Asus and Gigabyte. The HPT 372 offers RAID 0, RAID 1 and RAID 0+1 (requiring 4 disks). The on-board Promise controller is intentionally crippled and does not offer RAID 0+1.

The BD7-II is based on Intel’s updated 845E chipset, which comprises the 845 “Memory Controller Hub” (MCH) commonly called “Northbridge” and the “I/O Controller Hub 4” (ICH4) commonly called “Southbridge”. More details are available here.
