Identify memory type

Is there any way of finding out what type of memory i have installed on my pc i.e. pc2100 or pc2700? I bought some no name brand about two years ago.

If it turns out i have pc 2100 and i install another stick of pc2700 will it automatically run at the lower speed?

Or is it all dependant on the fsb of the cpu?


Im running an Athlon xp 1800 with an Asus motherboard.

Thanks!!

This is a good place to start for identifying DIMMs, but it is a little old. It will most likely get you the chip's manufacturer (the chips on the stick, not the memory board itself). After that, the serial number break-down's *may* be a little helpful, but probably not.

But finding the manufacturer will get you half way there. With that, you can try to search for the serial number schemes for that manufacturer, and if all else fails, e-mail them and ask if they can send you that information (include the serial number, just in case they'd be nice enough to look it up for you).


Right now I'm trying to figure out what I have in 4 old DIMMs. Using that site, I found out two were Micron (128mb PC100 and 32mb PC66), one was Hitachi (no luck yet with deciphering the numbers), but I can't figure out the manufacturer of the 4th (though a sticker says it's 256mb PC133). Three out of four for manufacturers and fifty/fifty on the full specs isn't that bad... all things considered.

Also, I'm not sure, but with your newer mobo (newer than the celeron 400 I'm trying to get this RAM together for) you may have some BIOS detection methods, so check for that.


Good Luck.
