Reply With QuoteSometimes, the actual ram chips need to be on both or one side of the board, try to find a chip that is opposite of what you have (and still 512mb). This is from my experience with older boards, but not VIA EPIA specifically.
via epia 800 - 512MB RAM
I recently bought a used via epia 800 since my plans for my carpc don't require any more power than that. The specs and instruction manual for the board clearly say that it supports up to 512MB RAM in either slot, for a total of 1GB. I made sure of that before I purchased. I pulled a single 512MB stick out of an older computer which originally had 1GB and installed in my new epia800. However, it only reports 256MB. It seems to be running fine other than that, but I can't seem to find a way to make it recognize the other 256MB available on the chip.
Has anyone else run into this problem on this board?
Also, I've looked for bios updates and haven't been able to find any for this particular board. If anyone has any suggestions it would be much appreciated.

Thanks for the suggestion. I'll try adding the second chip or swapping them around when I get home from work. It still seems weird, the memory works fine in the other computer and the documents say this board should be able to handle it just fine.
No go. Same problem with the other chip or with both chips. Except that with a gig installed I actually get 512 back. Does anyone know of any bios upgrades available for this motherboard?
Try clearing the CMOS? Maybe some bad settings is causing the problem? Just a guess...
Was the RAM from an Athlon system? If so, it's probably a chip density problem, as Athlon boards added support for higher-density chips that were cheaper. Most other systems will see half of RAM like this.
How many chips are on the DIMM?
The ram is from an Athlon system. Each DIMM has 8 chips on either side for a total of 16 chips per DIMM. I've never heard that there was any difference between AMDs SDRAM and Intel's SDRAM before. But the explanation makes sense.
