Thanks for the heads up. Bad cut n paste of URL on my part.

Nice read.

Nice read. The part that showed the difference in gaming between 2GB and 4GB was intriguing.

AN804 is also a good read as it is specifically for gaming. And, the playability aspect of minimum and average frame rates is much more important than max frame rate.

Have 1g with 2 512 ddr2-sdram (667 mhz).; want to at least double capacity.  How do i determine number of pins?

The fact that it's DDR2 is the determining factor mostly. If you have a laptop, go look for laptop memory, if you have a desktop, look for desktop memoy......that is DDR2 667

Make sure it has the same voltage and latencies as your so you won't run into any problems.
