Is that link a go for ordering my 1GB stick, and when i put it in my new 9300 ought I add it to the 256k stick that Dell is shipping it with or replace it? Thanks for your help!
No no. First, while it may be technically possible to run mis-matched memory sizes it is never a good idea - it destroys throughput.
Second, these are dual-channel machines. What this means is you need a pair of sticks (sodimms) that match in terms of size and speed, preferably the exact same type. The memory works in pairs - with only one stick, you give up on dual channel capabilities and thus speed. You don't want to gimp a nice laptop like the 9300 like that.
If you want a TOTAL of 1gb in your 9300 then you need to buy two 512mb DDR2 PC4200 sodimms, remove the 256mb in your laptop (actually, I am betting it is 2 128mb sticks) and install those in their place. Then sell the stock memory on ebay or something, although I am guessing there isn't much of a demand for 256mb of DDR2 laptop memory right now.
The 1gb stick listed in the link is if you want 2gb in your system, like me, or the original poster. Do you need 2gb? Depends what you use it for, but probably not. I've always tried to stay ahead of the memory "curve" and 2gb does reduce disk caching during certain games or when I am editing in Photoshop, but I would probably do just fine with 1gb if I had to. I think the price right now for 2gb is good and so I'll get ahead of the game now.
