In order to find out whether your 5VGM mainboard is an 5VGM0 or an 5VGM1, you will have to look at the PCB markings, which are located between the PCI slots on the board.

5VGM M101 or 5VGM M102 indicates an 5VGM0.

5VGM M201 or 5VGM M202 indicates an 5VGM1.

If you want to find the latest BIOS update for your mainboard or report a problem that cannot be solved by any of the answers in this Q&A section, then you will need to distinguish between the 5VGM0 and 5VGM1, since their BIOS code is different.

Does my 5VGM0 support MMX CPU`s ?

The 5VGM0 (PCB 5VGM M101 or M102) only supports the Intel MMX 166Mhz CPU. Please use a recent BIOS update when using this processor, which is the best performing processor for this mainboard. The AMD K6 Series or Cyrix M2 processors are not supported by this mainboard.

Which MMX CPU`s does the 5VGM1 support ?

The 5VGM1 (PCB 5VGM M201 or M202) was released later than the 5VGM0 and fully supports the following MMX CPU`s:

Intel MMX (also called P55C) at 166Mhz, 200Mhz and 233Mhz. The 233Mhz is obtained by using the same frequency settings as for the Pentium 100Mhz= 66 x 1.5, the 233Mhz MMX processor uses the 1.5 factor as 3.5 internally.

The AMD K6 series is supported at 166Mhz and 200Mhz. However, the 200Mhz version is not recommended, because of the limitations of the linear regulators on the 5VGM board. If you do want to use a 200Mhz on your 5VGM1 board, then please make sure that you are using a high quality fan (ball bearing), point the airflow of the fan at the regulators, make sure the case is ventilated sufficiently and do not expose your system to temperatures of more than 30 degrees Celsius.

After testing the new Cyrix M2 or 6x86MX processors on the 5VGM1 mainboard we have found that the overheating problems when using this processor are the same as with the AMD K6 CPU. Besides these problems, there are also timing related issues which prevent the board from being able to use this processor type.

The 5VGM1  therefore does not support this CPU series !

After installing the Matrox Millennium II card, the system cannot startup

The older BIOS versions do not support the Matrox Millennium II. Please download the latest BIOS update for your 5VGM mainboard and update your BIOS to solve this problem.
