Thinkpads Forum

I may get the opportunity to buy a 1gig memory stick that came out of a Toshiba that was purchased in September. My thinkpad currently had 1gig (2x512mb) of memory. Would there be any issues running a 1gig stick and a 512mb stick?

Eventually I would like to get 2gb in here.

There is no problem with using two different size memory modules.

There's no problem as long as they're compatible memory. You need DDR2 PC2-5300 memory (DDR2 PC2-6400 is also fine).

If you install two differently-sized modules, your system will no longer operate in symmetric dual-channel memory mode. However, The performance decrease is negligible.

Then I'll look into getting the 1gig stick of memory. I do game occasionally on the laptop, but when I do I usually run out of memory and then it would start paging.
