I have a laptop with a 256mb ram module in one of the two slots, is it OK to put a 512mb in the other. I'm sure I've heard with DDR2, you must only put same size ram in each slot. Does it just work faster in matched pairs? Thanks guys!

It depends on the chipset and OS you are running. If you are using a chipset that allows non-paired memory and Windows XP then yes you can. Although, you will experience some loss of performance by not having a matched pair. CRITICAL!!!: make sure you are using two memory chips that are running the same speed or this can cause other more drastic problems with your hardware interface.

It'll work only if the frequency of both modules match.
I mean,if you have 256 DDR2 RAM module with 667 MHz, you'll have to add module of 512 DDR2 RAM with 667 MHz only.
Other frequency modules such as 800 MHz or 533 MHz will not work.Just check that the frequencies match and you should not have any problem in putting 256 DDR2 with 512 DDR2.

DDR2 memory modules should be installed in pairs of matched memory size, speed, and technology.
If the DDR2 memory modules are not installed in matched pairs, the computer will continue to operate, but with a slight reduction in performance.

the ddr2 ram will in uncomplicated terms run on the gradual velocity of the ddr ram , your motherboard additionally needs to assist ddr2 with is maximum intel boards interior the the final 6 months. AMD motherboards dont help ddr2. however the hot AMD AM2 processor and board does help ddr2

you need the check your motherboards manual as you are correct,some boards you need to install 2 x 512mb modules or 2 x 256mb modules,it all depends on the board
its best to go directly to your boards website,you should be able to find your motherboards name under device manger,look under system underneath u.s.b devices
another good way of finding out is going to http://www.crucial.com/,and rub the system scanner
good luck

It will work better with matched pairs, but you can still install it and it WILL work.

They will work, though they will work at the slowest chips speed.
