6. Install DIMM Modules

This motherboard has three 168 -pin DIMM sockets that allow you to install PC100 or PC133 memory up to 1.5GB. This motherboard supports not only SDRAM but also VCM and Registered DRAM.

Tip: The driving capability of new generation chipset is limited due to the lack of a memory buffer (to improve performance). This makes DRAM chip count an important factor to take into consideration when you install DIMMs.

8. Connecting Redundant SPS Connector

This motherboard implements Redundant SPS connector to provide better expansibility on superior server. It is feasible to install an additional 337-watts power supply module (optional) in a hot-swappable redundant configuration, which enables a fully-configure system to continue running even if one power module fails.

7. Connecting ATX and AGP Pro Power Connector

The DX34 / DX34Plus uses Intel® SSI (Server System Infrastructure) type 24-pin ATX power connector. The 6-pin AGP Pro Power connector provides extra +5V and +3.3V power for AGP Pro VGA card. Make sure you plug in the right direction.

9. Connecting IDE & FDD Cable

Connect 34-pin floppy cable and 40-pin ATA66 or ATA33 IDE cable to floppy connector FDC and IDE connector IDE1, IDE2. Pin1 of cable is normally marked with red color. Be careful of the pin1 orientation. Wrong orientation may cause system damage.

AOpen DX34 PLUS Install Dimm Modules, Connecting Redundant SPS Connector, Connecting ATX and AGP Pro Power Connector

DX34 PLUS, DX34 specifications

The AOpen DX34 and DX34 Plus are notable examples of early computer motherboards designed for the Intel Pentium processors. Launched in the mid-1990s, these motherboards catered to the growing demand for robust and versatile PC platforms, emphasizing compatibility, performance, and expandability.

One of the primary features of the AOpen DX34 is its support for Intel’s Socket 5, which was designed for the Pentium series of CPUs. This allowed users to harness the power of early Pentium processors with clock speeds initially ranging from 60MHz to 120MHz. The DX34 Plus model further enhanced this capability, supporting faster processors and offering better thermal management solutions.

The DX34 series is built upon the Intel 440FX chipset, widely praised for its stability and performance at the time. This chipset provided essential features such as integrated support for Level 2 cache, which significantly improved data processing speeds by storing frequently accessed information closer to the CPU. The inclusion of the PCI (Peripheral Component Interconnect) bus provided compatibility with a range of expansion cards, allowing users to configure their systems according to their needs.

Another noteworthy characteristic of the AOpen DX34 and DX34 Plus is their memory support. The motherboards accommodated up to 512MB of EDO (Extended Data Out) DRAM, utilizing three DIMM slots. This made the boards suitable for numerous applications, from gaming to business tasks, ensuring optimal performance as software demands increased.

In terms of connectivity, the AOpen DX34 series featured several expansion slots, including PCI, ISA, and a few ISA bus slots, allowing users to add sound cards, network cards, and more. These expansions offered flexibility and customization, making it easier to upgrade systems as technology evolved.

Overall, the AOpen DX34 and DX34 Plus represent a significant step in the evolution of computer technology during their era. With their focus on processor support, robust memory options, and versatile expansion capabilities, these motherboards laid the groundwork for more advanced computing solutions in the years that followed. They exemplify the innovation and engineering that helped shape the modern PC landscape, and their influence can still be felt in contemporary hardware designs.
