I have an old Shuttle board (AK32V2.1) and the specs state that the max speed of ram it handles is 2100.

I just acquired two sticks (512 each; PC2700) of RAM. When I install one, it tells me that I only have 256MB installed. When I put both in, it only recognizes 512MB. Seems to be halving the amount. It's probably due to the speed incompatibility. If you have an answer to this, great, but that's not really my MAIN question.

Knowing that the two sticks are running at 2700 and the board only supports 2100, will they cause harm to my mobo. I them in right now and I don't see any immediate problems.

Thanks in advance.

The speed shouldn't hurt anything, there may be an issue with the size of the DIMMS, maybe the mobo is limited to 256mb/ea.

Edit: Just looked it up on crucial and the board will take two 1gb DIMMS.

Usually- The RAM will just run at the slower speed. Same thing with PC 100 / PC 133.

Are you sure they're 512s?

The RAM is probably not running at 2700 but is running at 2100.

I have seen double sided DIMMS show up at half size in a MB before, or as stated above it could be the MB.

Downlaod a copy of Memtest386 and test the memory if it passes I would not sweat it.

Thanks guys. It's been on here for almost a day now and nothing has happened. I finally got one of my favorite games going and been playing it all day. Superbike 2000.

ram is backwards compatible, you most likely need a to update your bios to get the ram to work correctly.. or you have really crappy ram

I have seen many motherboards that the slots can only read a certain amount in each slot. So if it can take upto 1gig and has four slots, thats 256mb per slot.... Its only reading what its designed to read.
