Question on memory configuration

[albertz]

I've been reading this forum for some time. And I'm about to place an order for an X61s (running Vista Business). But I'm confused by the memory configuration part.

I think I'd be getting 2.5GB of memory: a 512MB DIMM from Lenovo and buying a 2GB DIMM from Crucial, like this deal at buy.com

My question is this: is it a workable choice? why doesn't Crucial's memory advisor tool show it as a possible configuration? (It does show up when searching for product number 112803 though.)

Thanks in advance.

It is, however it won't work in dual channel mode.

Thanks so much for pointing it out!

My choice would be to replace the 512MB DIMM that comes with the X61s with a 2GB kit (2 DIMMs) from Crucial. The question is then, is the standard DIMM removable?

Thanks.

All RAM chips are removable.
