How to find the Bus Speed in the Ram
Trying to add more RAM in addition to the one it already has on a friends computer and I would like to determined the amount of Bus speed in that RAM. All I know, is that it's a DDR 256MB RAM. I already took out the RAM to inspect it to see if I can find anything written that may say either PC2700/333B or PC2100/233B but had no luck. Does anyone know how to check the bus speed on a RAM chip?

Thanks, but those websites don't appear to give the particular information that I'm looking for.

Thanks StillLearnin'
I was looking for a benchmark that can show me the bus speed of a RAM. Your example make's it much clearer what Aida32 can read and print out, unlike the website info. I wanted to determine the bus speed of the RAM so I can match it with the new one I'm going to install. Even though I know it's not necessary to match the bus speed, but why buy a PC2700/333B Ram if it can only run at PC2100/233B if the old one is PC2100/233B.

Download the Enterprise edition and run it. The program is invaluable. PC2100 would run at 266 not 233. "Usually" PC2700 is backwards compatible with the PC2100/266. If your mobo doesn't support the 333 bus then it should run at the 2100/266 speed. Lately the PC2700 has been cheaper than the PC2100. If/when you upgrade to a mobo that can run 333/400 bus speeds, the PC2700 will still work whereas the PC 2100 may not.
