A-Trend ATC6240 Slot1 Intel 440BX motherboard

Thursday, May 27, 1999

Introduction

Founded in 1990, A-Trend Technology is a 570 employees company with an annual revenue of $246 million and a 52% growth rate. The name of this motherboard manufacturer may tell's you nothing but it is nonetheless a well recognized motherboard manufacturer by the connoisseurs. This new product from A-Trend, the ATC6240 Slot1 based on the Intel 440BX chipset, is a good proof that these peoples are experienced manufacturers. Adopting the 5/2/1 design and a very clean look, the ATC6240 is really giving the feeling that it has been designed for the serious users.

Let's forget the blah blah and follow me for a more detailed look at this motherboard in the following review.



The Features

As mentioned in the introduction, there are 5 PCI slots, 2 ISA slots, 1 AGP port and 4 DIMM slots like it can be found on most of the motherboards nowadays. The ATC6240 can therefore allow up to 1Gb on memory for a very comfortable operation. Most of the PCI and ISA connectors can use full length cards as only the second ISA slot shared with the fist PCI slots could refrain the use of full length cards because of the front panel accessory connectors.

The clock frequencies offered on the ATC6240 are rather limited and you can only choose between 66Mhz and 100Mhz. This is what I said until I had a message from one of the visitors named Majuran who sent me the following message " in the BIOS there is an option called "software clock control" under "Chipset Features", and if enabled, a hidden item pops up called "CPU Clock Frequency". As I have a 100MHz Chip, it will only show me the frequencies over 100 which were 100, 103, 112, 124 and 133 as far as i remember, but there must be a similiar variety between 66 and 100". Grrrrreat thanks to Majuran Manohasandra as I completely missed this feature but shame on me....

The FSB frequency is selected by jumper JP11. When you use the 100Mhz setting, there apparently is a SEL66/100# option enabled has I could easily Overclock my PII 350Mhz to 400Mhz with this setting by using a 100Mhs FSB frequency and a 4X multiplier instead of the 3.5X default setting even if this processor has a built-in multiplier lock enabled by default. The clock multipliers can be set from 3X to 6X in steps of .5X. There is no processor core voltage adjustment on this motherboard as this parameter is automatically adjusted to corresponds to the processor detected. By the way, contrarily to what can be found on many other motherboards, there are no Turbo setting option on this motherboard. In other words, you can't give to this motherboard a little push to further enhance its performances.

Additional features such as: Wake up on LAN, PS2 mouse and keyboard connectors, USB connectors, Irda TX/RX header, SB-Link header, Keyboard power-on, Wake up on modem ring, CPU Over Voltage Protection and hardware monitoring (as an option) are all supported.

Installation

The installation of this motherboard is a quite straight forward procedure. The only steps required are to decide if you wish to set the FSB to 100Mhz or to the Auto setting and then set the Dip switch multiplier value to match the processor frequency.



The Software Bundle

The software bundle included with the ATC6240 includes: Intel PIIX4 Bus master drivers, BIOS flashing program, an Intel Microcode updating program and LCDM (as an option).
