What We Like

As with most 845G boards, features and integrated devices are normally lacking. However, this is not the case with EPoX’s EP-4G4A+. Unlike most of the other 845G boards we’ve seen so far, this is one that deserves a mention for being one of the most highly integrated motherboards around.

First, you’ll notice that the board comes with an ATA-133 IDE RAID controller. Based on the HighPoint HPT372 controller, the board offers you the ability to add another four hard disk drives configured for high performance storage. Unlike the on-board RAID solution provided by Promise Technology, HighPoint allows one to configure RAID 0, 1 and 0+1. The RAID 0+1 capability is what a lot of the power users want, since it is able to perform Stripe and Mirroring on four hard disk drives. That gives you both performance and redundancy.

The HighPoint HPT372 offers RAID 0, 1 and 0+1 on four ATA-133 hard disk drives.

The board also comes with an integrated LAN controller. The 10/100Mbps Fast Ethernet controller is based on the Realtek RTL8100B one-chip solution. Although the ICH4 south bridge has an integrated Media Access Controller (MAC), EPoX decided to use a much simpler one-chip solution for its built-in Fast Ethernet.

The Fast Ethernet LAN is driven by Realtek's RTL8100B one-chip Ethernet controller.

Besides that, you'll be getting up to six PCI slots with the EP-4G4A+, giving you total control of what you PCI peripherals you want to install. Judging from what's offered, there's a lot you can do with this board and the expandability options are good.

For those who wants only audio, EPoX offers the ALC650 AC'97 audio codec. Providing users with 5.1-channels of audio, you can comfortably play 5.1-channel movies on the system.

The Realtek ALC650 is a rather popular codec for 5.1-channel audio.

The power requirements on the 4G4A+ seems to be rather low. Unlike some of the other 845G boards we've tested, this one did not need the extra 12V connector. This is good news to upgraders since they need not buy a new Pentium 4 approved power supply. Of course, one needs to be sure that the re-used power supply has enough current to drive the Pentium 4.

The EP-4G4A+ uses only one ATX power connector to power up.

Overclockers would also like the EPoX 4G4A+ especially with its complete range of tweaks available to push the performance of the system to the max. Some of the settings available in the BIOS includes :-

  • System bus settings - 90MHz to 200MHz (1MHz steps)
  • Core voltage settings - +0.025V to +0.350V (in 25mV steps) and -0.025 to -0.100V (in 25mV steps)
  • AGP voltage settings - 1.5V to 1.9V (in 0.1V steps)
  • DIMM voltage settings - 2.5V to 3.2V (in 0.1V steps)

    Besides these settings, we were also quite pleased with the fact that the board is able to fix the AGP and PCI speeds to 66MHz and 33MHz respectively. Thus, there's no need to worry that overclocking the system bus would change any of these speeds which could be harmful to other devices.

    The rear I/O panel offers the user four USB 2.0 ports.
