Get the sticks from companies that send you the right sticks. Crucial.com does this quite well.
HOWEVER I see so little payback from 2 to 4GB that you won't find me doing such an upgrade unless I could skip a cheap meal.
I got some question please...
The story in short: I got a Dell Vostro 1000 laptop,what i would like to upgrade by changing my old pair of 2Gb (original 2x 1GB)memory to a new pair of 4Gb higher speed 800MHz (PC2-6400 / 4GB / 800Mhz / DDR2 / 200pin SODIMM / Computer Memory) if that possible. Now the reason, why i am asking you guys, because i have spoken to the Dell customer support, and they said is possible, but i have to remove the old memories, and install a new pair. that would not be a problem, but i have trouble to find the best memory for my laptop, because all the test what i read on forums, they said my laptop is NOT capable more than 2Gb. Therefore, i got so confused.(Confused.com would not be the best option ) so i thought, i know, i ask You guys instead , for a more sensible professional opinion.
Q1: is my laptop capable the above mentioned memory (4Gb etc)
Q2: what is the best memory what i can choose out of the memories what is on the market?
Q3: where can i find it out, is my laptop take 200 pin SODIMM? or is 240 pin?
Thank you for your time and help
