Asus A7V333 VIA KT333

Monday, May 27, 2002


The roundup of VIA KT333-based motherboards continues today with our review of the Asus A7V333. The first thing most users will notice about the A7V333, is that it stays true to the Asus tradition of offering a full range of Overclocking features. As is usually the case with Asus boards, these features can be accessed either through the plethora of PCB jumpers and Dip-switches, or through the more sophisticated and familiar BIOS system. As for features, well, the A7V333 comes with plenty of those as well: a RAID 0-1 controller, a six-channel sound-card, an IEEE-1394 "Firewire" controller, and USB 2.0 ports, to name but a few.

So, with all that in mind, lets say we take a closer look, shall we?

Characteristics of the Asus A7V333
Socket A for AMD Athlon XP/ Athlon/ Duron 600MHz ~ 2GHz+
VIA KT333 + VT8233A
Form factor
ATX - 30.5cm X 24.5cm
5 PCI - 0 CNR - 1 AGP Pro - 4 USB 1.1 + 4 USB 2.0
3X 184-pin DIMM up to 3Gb DDR SDRAM PC2700
100Mhz to 227Mhz in steps of 1Mhz
Vcore adj.
1.75 to 1.85v in steps of 0.025v
Vio/DDR Vadj.
Audio chipset
C-Media CMI 8738


The Asus A7V333's sound capabilities are provided by an integrated C-Media CMI8738 audio-chip. The CMI8738 supports 5.1 speaker-configurations, with 4 to 6 lines-out, including a central bass channel.

As we've mentioned before, the CMI8738 is head and shoulders above the audio circuitry that is typically included as part of most VIA chipsets, and its sound reproduction is simply excellent. Whether you're playing MP3s, CDs, or 3D games, the CMI8738's sound quality will often surprise you with its fidelity.
Please note that while SPDIF ports are present on the printed circuit board, the proper bracket and connectors are not included in the satndard package.


Configuration of the Asus A7V333 is a bit more complex than is the case with most other mainboards, due primarily to large number of jumpers, and BIOS functions.

On the board itself, users will find an array of Dip switches that can be used to Overclock the CPU, alter the Vcore voltage, or simply set the system to take its cues from the BIOS settings.

Most of the BIOS's Overclocking features can be found within the "Advanced" menu.

The foremost of the available options is the ability to set the FSB frequency to between 100Mhz and 248Mhz in 1Mhz increments.

Next, we have the ability to set the clock-multiplier value to between 6.5X and 14X.

The Vcore voltage can also be altered to match any of the values indicated in the table above, but, unfortunately, no options are given for the DDR, AGP, or Vio voltages.

As expected, a number of memory-timing related settings are also available for tweaking, and can be accessed via the "Chipset Configuration" sub-menu, within the "Advanced" menu. Available options include the ability to set the memory bus to a ration of 4:1, 5:1, or SPD (Serial Presence Detect) which allows the system to determine a proper setting automatically.
