IRQ Usage

  • Allows user to individually set IRQs for each Legacy ISA card

  • Allows user to reserve IRQ/DMA Channels if necessary

  • Auto-detects PnP Cards after HDD Detection

 


BIOS Settings

Here are my Recommended BIOS Settings for those of you who have been having problems with the TXP4-X and higher bus speeds, I'm not sure why though since it was very stable when I tested it. Below are my recommended settings for bus speeds < 66MHz, and 75MHz. If you are using Non-EDO RAM, then use the settings the in the 2nd (Non - EDO) column, if you are using SDRAM/EDO RAM with a 50/60/66MHz bus speed use the 3rd (66MHz Setting) column. The next column should be used if you are using the 75MHz bus speed and EDO/SDRAM. Finally, if you are looking for the safest and most stable setting, use the last column. There are more Chipset Features Setup options than those I have listed here, but they pertain to HDD settings as well as Serial/Parallel Ports and have nothing to do with memory timings so I left them out intentionally.

Recommended SDRAM

This little addition to my review layout was put in here just so you all can have an idea of what brand of SDRAM I recommend and have tested with the board, just to avoid problems in the future if you decide to purchase the board.

Recommended SDRAM: Advanced Megatrends SDRAM; Corsair SDRAM; SmarTech SDRAM
SDRAM Tested: 2 x 32MB Advanced Megatrends SDRAM DIMMs; 2 x 32MB SmarTech SDRAM DIMMs; 2 x 32MB Corsair SDRAM DIMMs

Manufacturer: Advanced Megatrends

The Test

In recent times, choosing a motherboard cannot be completely determined by a Winstone score. Now, many boards come within one Winstone point of each other and therefore the need to benchmark boards against each other falls. Therefore you shouldn't base your decision entirely on the benchmarks you see here, but also on the technical features and advantages of this particular board, seeing as that will probably make the greatest difference in your overall experience.

Test Configuration

Hard Drive(s): Western Digital Caviar AC21600H
Video Card: Matrox Millennium (2MB WRAM)
Busmaster EIDE Drivers: Intel 3.01
Video Card Drivers: MGA Millennium 4.03.00.3410
OS: Windows 95 Service Release 2
System Cooling: 1" Heatsink/Fan Combo
2 Case Fans
Generic OEM Mid Tower Case

It isn't the world's best performer, and sometimes it can give you a few problems when overclocking, however the TXP4-X offers performance that is true to the ASUS name =)

 


The Final Decision

This one is your call, if you just want a TX board, without any really special features, just an average TX board based on the ATX form factor which offers great performance and the backing of a great company...then the TXP4-X is for you, otherwise, I would consider the TX97 series instead
