I am tryting to upgrade a system whose motherboard's only visible ID is 5I VX1C. I have no idea who manufactures it.
The board has 4 EDO memory slots and 1 SDRAM memory slot. It already contains two double-sided 8MB EDO chips. I tried to insert a PC-100 64MB chip into the SDRAM slot. Extra memory was not counted at startup.
I then removed the original 16 MB EDO, and since then the computer will not even display the VIDEA BIOS information.
I have checked the output voltage from the power supply - appears to be right.
I have changed the PCI video card to another and then to an ISA video card - same results.
The system appears to start properly, lights on the devices all show properly, but the screen remains blank.
I have also connectedthe moptherboard to a different power supply, same results.

Any idea?

You have a: Intel VX Chipset with DIMM slot. MMX CPU, AMD K6 and Cyrix P200+ CPU supported

Looks like your motherboard is supported here:

Here is the product page:

Here is the picture of your board:

Here is the BIOS update page:

You cannot mix two different types of memory with this board, it's either you use ALL EDO or ALL SDRAM (not both).

I hope this helps you.

gdctek found some good resources for you.

I would add that many of these "first generation" DIMM boards are not compatible with the current DIMM configuration.
Many also have a very low limit on the maximum DIMM size that they can address.
BothKingston and Intel have papers on this problem.

You should be able to check what memory is compatible at Kingstons or Crucials web site.

You can probably have more memory using the SIMM sockets alone than from adding the correct DIMM.

The last time I checked, the used part sellers were selling 16MB SIMMs for under $9 each.
