QDI KuDoz 7E/333-A (VIA KT333) Mainboard

Products of this company are not widely spread, but at present QDI carries out a policy of expansion. You can read more about the history of the company, its development and peculiarities of production in our article on Legend QDI.


  • Package of a low-key but pleasant design;
  • Documentation: a user manual in English;
  • Cables: 1 ATA66/100/133 and 1 FDD;
  • Bracket for the rear computer panel;
  • CD with software including:
    • drivers;
    • user manual in PDF;
    • Adobe Acrobat Reader;
    • Norton Antivirus 2002;
    • Q-Flash (for flashing BIOS from Windows);
    • CBLogo (to add logos/images into the flash BIOS file, works under the DOS);
    • DirectX 8.1.

The layout is typical and has some typical flaws: audio-ins are put in between the PCI slots, and a power connector is between the rear panel's unit and a processor's socket. It's not difficult to reach jumpers and switches even when the board is already installed. Their functions are shown on the textolite.

The 3-channel switching voltage regulator incorporates 7 capacitors of 2200 uF.

The following controllers are integrated:

  • audio controller based on the Avance Logic ALC650 AC'97 codec with a connector for front audio-outs and supporting acoustic systems 5.1.

The board supports the following proprietary technologies: BIOS ProtectEasy (for protection from recording into flash memory of the BIOS chip), LogoEasy II (to display your own images during booting), RecoveryEasy II (for data backup into a hidden area on the same hard drive), StepEasy II (to change a processor's frequency from Windows) and BootEasy (for quicker booting) - you can read more about some of these technologies in the article mentioned above.

Non-unsoldered connectors: audio adapter based on the Creative CT5880.

The system monitoring is supported by the ITE IT8705F chip. What is controlled:

  • voltage of processor, +3.3, +5 and +/-12 V, VBAT and +5 B Standby;
  • speed of 2 fans;
  • temperatures of the processor (thermodiod in processor socket) and the board (a built-in sensor).

There are 2 connectors for adjustable connection of fans and 1 for non-adjustable connection.

Brief characteristics of the board: memory slots - 3 DDR SDRAM; expansion slots - AGP/ 5 PCI/ ACR; I/O ports - 2 COM/ LPT/ 2 PS/2/ 4 USB 1.1; dimensions - 305x220 mm.

Adjustment can be carried out with:

jumpers and switches Jumper to clear up the CMOS
Jumper to choose a FSB frequency 100/133 MHz
Switches to change a CPU multiplier Auto, x5-x12.5
Jumpers to set processor voltage 1.65-1.85 V in 0.025 V steps
Jumper to protect Flash EEPROM from writing
Jumper to start up computer with a USB keyboard
Jumper to start up computer with a PS/2 keyboard
Jumper to enable/disable the audio codec
BIOS based on the ver.6.00PG from Award Setup of memory timings + CAS Latency, Bank Interleave, Precharge to Active, Active to Precharge, Active to CMD, DRAM Queue Depth, DRAM Command Rate
Setup of memory frequency + 100, 133 and 166 MHz
Setup of AGP bus +
Setup of PCI bus +
Changeable scaler of AGP and PCI buses -
Manual assignment of interrupts -
Changeable FSB frequency + 100, 105, 110, 115, 120, 125, 133, 138, 142, 144, 150 and 154 MHz
Changeable CPU multiplier -
Changeable core voltage -
Changeable memory voltage -
Changeable chipset voltage -
Changeable AGP bus voltage -

We used the latest available version of the BIOS - 3.2.

This is an ordinary board without an extraordinary speed or capabilities of precise adjustment or overclocking. The only pleasant thing is that it supports the proprietary technologies.
