Quick question about adding RAM

[Milhouse]

Quick question; can I add a Kingston 1Gigabyte block of RAM to a T42p which is equipped with 512 megs?

The last computer I upgraded with more RAM was a old IBM desktop and only specific constellations of block sizes were allowed. I assume this is a thin gof the past?

Yes, you can do this. No requirement here for adding RAM of same size. From the Crucial website FAQ:

"Do I have to buy the same size upgrade as the memory module currently installed in my computer or can I mix different sizes? In newer systems using SDRAM or DDR SDRAM memory, you can use modules of different densities with no problem. For example, if your computer came with a 128MB memory module, you can add a 256MB module for a total of 384MB of RAM. However, if you have a "dual-channel" system and want to take advantage of that technology, you will need to ensure that the modules in each memory slot are the same density. "

I don't think the Thinkpad motherboard runs dual channel.

Thanks for the quick help!

I tryed a google search but couldn't fin dout if the mainboard runs dual channel, does anybody know this?
