What is the best RAM for a Laptop?

[Inphinity]

i am trying to figure out the best type of RAM to put into my IBM T21 and would like to know your guys opinions.

PS... can i use PC133 ram even though my systems bus is only 100 MHz, or do i just have to use PC100

PC133 ram is backward compatible with PC100 even on laptops..
I beleve that the same rules apply to Laptop memory that apply to PC memory..

some pc100 notebooks will not boot with pc133, so be careful

I don't know if it's the "best" or cheapest ram you can get for a laptop, but you could use an online vendor like www.18004memory.com that guarantees compatability if you use their memory configuration utility to select the right ram. In my case I used their configurator and it turned out to be the wrong kind, so they gave me a refund. I ended up finding the correct type of ram cheaper from kahlon.com which also uses a configuration utility (but I'm not sure if they guarantee compatibility). You can start at pricewatch and just use trial and error to check prices from different ram vendors, and hopefully find a good price and a guarantee.
